Celica Forums General Discussion Engine and Performance JET Performance ECU Chip

Wow... I got my ECU back a couple days ago. Here are the stats before and after!
Before - After
HP: 180 - 204
0-60: 7.3 - 6.9
Top Speed: 140 - 156
The chip isn't cheap it set me back about $360.00... I think it is worth every penny! My next $250 will go towards getting the V-Force Power Control Module. Which is a 20mhz RISC microprocessor that optimizes the ignition spark advance and recalibrates the fuel map for optimum horsepower and acceleration. Also made by JET. With those two parts plus after I upgrade my fuel pump and ignition set up from stock to street I will ball park it at around 225 - 245 horsepower.

now watch in a week as your results disappear...poof! your ecu has detected something wrong and has re-set your settings to stock


btw-we need to see a dyno.

sweet ass... Jet might be the only chip that will work for the Celicas.

those are nice gains and seems to be more legit than the "chips" you can buy from ebay

Do you feel a big diff?

I didn't Dyno I used my friends thing. It plugs into your grit lighter and mounts on the dash. It's like a 200 and some odd dollar thing he has. Very nifty! Also tells you your G-force durring turns and shit!

so you used a jet chip and a g-tech to figure out your hp gains?

Oh my god yes! That's a hell yeah! I drove home normally and when I left again that night I romped on it durring the on-ramp. I felt it pull a lot harder! I really wanna see what it will do if I upgrade my stock fuel and ignition set up!

please let us know if you still have the same performance in a week or two...

I'm hoping to have faith in the JET ECU, if it does in fact work, so hope you can dyno your car. That's the only true way to determine if you gained anything.

Using the GTECH for HP readings sucks. But you said your 0-60 went down from 7.3 to 6.9, which is almost 1/2 sec faster. Did you test it on the same road and launched exactly the same? Otherwise you can't count on that being accurate either.

I didn't use the "chip" to figure out anything. Just my friends appliance thing. I don't know the name but i'd be happy to let you know when he gets back from work.

No prob! It's been 6 days now so i'd say around day 14 i'll check the stats again and let you know where i'm at! If i can dyno it i will!

right...

oh with a turbo?

The PFC is the best and even with the best tuning and upgrades available so far, N/A people have not seen 225 hp at the crank. That may be possible with cams. But certainly not with what you listed.

No way... i disagree and i guess the only way to prove it is when i dyno... ::sigh:: ...But then at least i will prove you wrong! MWHAHAHA! I will dyno with, JET ECU Chip, TRD Exhaust, DC Headers, Injen CAI, and Upgraded fuel and ignition! I will prove to the world that all motor celi's can get over 225! OVER 225 I TELLZ YA!

everyone knows this...but i want to give him a fair shake and see what happens.

OH THANK YOU! And btw it was a G-Force Pro Performance Meter RR.

^^^ well, no one has tested the Jet Chip before, so we cant say for sure. yes i do know that most "chips" will be overridden by the ECU but you would think NOPI knows better than to sells things that will not work.

But I do agree that without a turbo, he might not be able to reach or break the 225hp range. most likely if the jet chip and other product that is suggested works he can get to at least 210hp. we'll just have to see what happens.

Is the unit just plug and play? Is there any tuning involved?

No it is soldered on to my ECU. The V-Force Power Control Module is wired in some way considering it is a what it is.

let us know as soon as you dyno

NOPI knows it works on certain cars...but i doubt it workd for ours. Check new celica...people were disappointed

anyone want to put money down?

first you need a real dyno
then you gotta tell us if the factory ECU slaps what you did outta the way and just goes back to normal

DYNO that bitch already!

jet repalces some of the ecu chips so it will not reprogram it self like it will with a safc or other piggy back unit

very nice

THANK YOU! I thought so too but i didn't say anything cause i thought if i was wrong CT would eat me alive like his freaking cat stuffing his face.
>>>Just playin' CT love the icon!<<<
Anywho yeah i'm going to run the celi again for stat changes a week from now right before i install the control module and my fuel & ignition set up. After that is all outa the way i'ma dyno it. I might spring for flywheel and clutch before the dyno cause the shit ain't cheap and i don't wanna have to be back in there a month from then scartching my head wondering if the clutch did anything. Oh! Can't forget the AEM true power pulley!

how's the clutch gunna improve your hp

I guess with all these extra buys I am springing for in a hurry cause I wanna break 225hp now, Santa is coming late this year!

Read up about all the people having their oil pumps fail catastrophically while using aftermarket pullies before getting one yourself.

Well gee i wonder... a lot of HP get lost in the drive train and tranny and never makes it to the black top. I'm try to help make sure all my ponys get to where they need to be!

read up on how AEM pulley isn't like the other pullies noob

so wait, this won't make the ECU go back to normal?
hmmmm

LOL! WOW! Yeah might wanna look into that huh?

yea you get a little torque outta it and hp
best to do it with a lightened flywheel also.

DAMN SHOT DOWN! Owch i felt that one... I can work on Black Hawks but i guess a Celica is out of my league?! Yeah i always read on shit before i buy it. So, i'm sure i would have caught myself on that one anyway. But thanks for the info!

That was the plan.

well i hope it works despite the criticism. the PFC cost too much anyway.

and PFC don't work with 03 up GTS

This thread is worthless without a dyno...

^^^

well, RYO told me that he sent his ECU to Jet where they soldered the chip onto the ECU. If the improved conditions last, they prolly did something else to the ECU.

BTW, I plan on making some Chips for the Celica, anyone interested?

we'll see...

if you got a dyno (not a g-tech) and/or a timeslip (on a real track) in around 2 weeks then i'll believe it. too many people have tried this at new celica.org and it's been beaten to death...

Damn you're giving me two weeks to do all of this? In a week i'll post if the ECU is still pushing. Give me 2-4 weeks for the purchase and install of the other parts and dyno. Shit i'm not superman... My wallet isn't that deep...

Thank you i'll be sure to thank you when all is over with!

just wondering, but how did it know your top speed?

no...i meant do it after two weeks...and a run at the track shouldn't be too expensive...plus some dyno places go for around 45-65 bucks

if you mees with the air/fuel ratio you'd want to dyno anyway rather than just put a chip and leave it be...

I'll bump this thread in a month if I don't see it around.

2am + 4.5 mile stretch + Celica = Finding Top Speed

^^^ Honestly i'm not trying to sound cool nor would i recomend anyone to try driving at those speeds. The only reason i knew i could go it safely and get away with it is b/c i grew up in my town. I know it like the back of my hand. DON'T BE A DUMBASS AND TRY GOING 140 EITHER. Unless you have the driving exp and you know what your doing. No, watching TF&TF or 2F2F doesn't count as knowing how to drive.
STAY SAFE! DRIVE SMART!

from a stop? or a roll?...

I agree

to have 225 hp you'd have to be around 192whp. thats NOT likely

also the g-tech is highly reliant on vehicle weight. and it gives you whp #'s NOT crank hp. so what did you use for weight?

also if that is 204 bhp then you're at 174 whp assuming a 15% loss. thats average for most people having I/E only.

so tell me again why this "chip" is so special????? I myself dynoed 170 whp with I/E and 185 WHP after the power fc.


but hey if you're happy, that all that matters I guess.

but until you get real dynos don't try posting all over the boards that this is the greatest mod ever. cause from what you've shown so far it's not worth $1 let alone $360

i wish my celica did 0-60 in 5 seconds

I wish mine did 0-60 in 4.5 seconds instead of 4.7

You need TPR

you got yourself a nice expensive 360 dollar sticker.

I feel bad for you once you dyno 160-170whp.

ah poop on you

When you say 180 hp and 7.3 0-60, did you get that on the g-tech or did you just take that from somewhere. Because obviously like lucky said, you have to enter your cars weight and it is only accurate if you put in the correct weight etc and that wouldnt be comparing anything if you didnt use the g-tech before the chip. I mean obviously you did not gain that much horsepower. What would be helpful is knowing if it does work without getting overrode though.

haha i poop on mike too...lol...i wish my auto gt was that fast.

gtech is very accurate

Yes it is. However, it is only as accurate as the numbers you put into it. If you went to a weigh station and got your actual weight with you in the car then its one thing. But just punching some number in doesnt work too great.

accurate and precise aren't the same thing.

so are we still waiting for the dynos

Whats your point? Precise just means reproducible. If its accurate everytime (close to the actual value) then its going to be precise.

that is my point. you assume it is close to the actual value of say a dynojet. show me the proof.

Incase you're spacing out those are the stock specs on a GTS and when i ran it before i got any upgrades with the g-tech guess what it said... 180hp 7.3 0-60.

bhp, whp?...don't need to say any more.

i wud say the 180 is from crank..

does a certain person see the issue then?

180hp = stock crank

How is the ecu going to override a new ROM that's been soldered onto the ECU in place of the factory one? Ever think of that? Yea, it'll override some piggybacks, but if you desolder the rom with the fuel maps and such, and replace it with a new one, there is no way in hell it's going to be overrided at all, you are essentially reprogramming the ecu altogether, you're not altering sensor signal voltage, you are changing the way the ecu itself operates.

If it was going to override, it would've done it already, but since many of you just post the typical response, without actually reading his posts (which state what he did) you would get this fact.

Problem is, chips have gotten a bad rep in the celica forums because of ebay jerkoffs selling resistors and selling them as "chips". This is not a true chip. A real chip refers to a new ROM with a new program, which replaces the factory ROM chip. ROM stands for "Read-Only Memory" which means it can NOT be overwritten by traditional means. You must use FlashROM for that, and only a specific piece of hardware called a "ROM burner" can clear and rewrite it. Most import ECU's do not incorporate the needed hardware to do this, so you need to physically remove the ROM, and either re-flash it on external hardware, or replace it with a new ROM with a different program.

So, you need to send the ECU in eh? that's handy to know, this means that there is no external port on the ECU to install an external ROM. The reason you need to send it in for the upgrade is simple, they need to de-solder the actual ROMs and replace them with a new one. Some roms can just be swapped out, since they use a socket, other ECU's (like the ones on most domestics) have an external port, you simply plug the new ROM into the ECU externally. Nowadays, most ECU's can can be "Re-flashed" through the ODBII port (Look at things for domestics like the Hypertech power programmer), overwriting the factory program on the ROM with a new one. However, since toyota isn't being forthcoming with ECU specs, the only method that would work would be to replace the ROM by desoldering, and putting a new one on the board/soldering it down.

This is clearly what has been done in this case.

The V-Force has gotten mixed reviews for the celica, most of them negative, but then again, I suspect it would work properly if you swap the ROM out for JET's beforehand. I suspect you should get decent results.

Only drawback is this: if you upgrade, say, add forced induction of some sort, you will need to change the ROM again, which means sending the ECU out again, to be desoldered, reprogrammed, and then re-soldered, unless of course JET had the foresight to solder a socket in place of the factory ROM, making future program changes easier.

PowerFC is a good option for those who would change their tuning frequently, it has flashROM, and includes the needed hardware to re-program the roms with an extenal device. While the JET upgrade may actually be effective, major upgrades will require you to send out the ECU, which means more downtime.

However, I would suggest to Ryo that he get an actual dyno run on the car, just to confirm the results.

Sounds interesting, keep us posted

Are you talking to me? I don't own a g-tech so I probably shouldnt talk about how accurate (or reproducible lol) it is. I am just going by what everyone has said. If you are talking to me, I think we have been agreeing about it anyways as to how what you input into it has to be accurate and you cant be on a slope etc.

What it comes down to is if you will believe that this chip that is only 360 dollars will peform just as good or perform better than the powerfc which is 1000 dollars. I will believe this when I see it. The powerfc is a standalone unit that is tuned for your car. The JET is just put onto the stock ecu. But yeah, get that dyno and if I am wrong I will gladly admit it.

I own a Vector performance meter, they're very accurate if set up correctly.

Of course, if you don't input a proper HP correction factor, it will usually give you the wheel HP, the base configuration on most performance meters usually doesn't account for parasitic loss from the drivetrain, aerodynanic drag, etc.

I have my meter calibrated to give me crank HP numbers personally, there's about a 15% drivetrain loss on an auto GTS, and about 8-10% loss on a manual tranny.

you definitely want to make runs on as level a surface as possible, but of course, most dynos don't include factors like rolling resistance, wind resistance, etc. So in some cases, a performance meter is more accurate, rather than less.

Some dynos are more accurate than others. You can always make a dyno run, and use the results to dial in a performance meter, which will help make readings more accurate.

Of course, the best thing to do is to make multiple runs, and average the difference. this is the best bet with either a dyno or performance meter.

How about we just get a dyno.. and settle this

the website looks legit, it may be true, if you think of how many chips they sell at 400 bucks each it must do something

no, so don't worry about it man. apparently he hasn't figured it out yet lol.

im really interested in just feeling a difference in power, but numbers would be sweet, the website shows numbers on a camry, but not sure if the ecu is similar, i know dude that had one on a 4.3 s10 and the difference was unreal

ok assuming 8-10% loss on manual tranny and he says he can at least get 225 hp at the crank with his original listing of upgrades...that means about 202.5 whp at worst.

Who wants to put $360 down that he doesn't hit 202.5 whp on a dynojet?

If he's right, he gets his JET paid for.
If he's wrong, JET means "Just Empty Talk" (from the company of course).

Any volunteers?

let's wait for a couple of weeks and see if the butt dyno picks up that extra 50 crank hp...

10 and ill buy one,

I want something like the PFC for an 03

No, actually what it comes down to is the quality of the tuning. The factory ecu is more than capable of doing almost anything the PFC can do, after all, it handles all the same functions on our perticular application from the factory.

The difference, other than price, is the fact that with JET and other major chip manufacturers, you need to fill out a worksheet telling them the engine specs, and they tune their ROM for the modifications you put down on the form, They'll ask abourt the cam profiles, compression, turbo/SC/nitrous settings, etc, and they tune based off of what you tell them, unless of course you take your car to their headquarters, in which case they'll tune the ROMs with the vehicle on hand. If you are off on the specs you submit to them, the tuning will not be optimal.

Don't sell JET short; they've been making and distributing their ecu upgrades for ages, way longer than the PFC has been around. Their street chips usually use a base map, like the pfc, but they change those maps based on the mods you have. They also don't limit to one base map, since, along with the engine specs, they go off the ECU model number. Because hardware revisions of the ecu usually differ, the GTS may have as many as 20 or more different ROM sets between all the model years. Also, if they don't have a map for your ECU on-hand, Jet, as well as many other similar companies, will make one for you for free, just so they can add that specific hardware revision to their available application list.

I'm definitely not knocking the PFC, it's a nice tool, the tuning is very flexible, and it has options for expansion beyond the factory ecu for additional sensors, injectors, etc. I am not disputing this fact, but some people do not need all the extra bells and whistles, and as far as I know, most people don't have a Dynometer in their garage, so the fact that it can be tuned by the end-user is lost on most people.

However, for most tuners, they can get identical results from a ROM upgrade if it's executed properly, and it may even be more reliable.

The one thing the Jet upgrade has over the PFC is that it's 100% ODBII compliant to the factory specifications, and is street legal in all 50 states.

Hoooo shit i'm pretty sure you just got served!

LOL. Actually NOT "quality of tuning". More like tuning in general. I don't call punching in numbers according to specs and descriptions tuning. You did say most people who get aftermarket ecu's won't get around to tuning, so even if they did bring their JET into headquarters to get tuned, I don't think these guys will spend hours on the dyno like Lucky and others have spent to get the numbers you claim you can get with JET.

something tells me JET doesn't tune the vvti with their number punching, and that according to Lucky is where he got the most gains with the PFC.

big deal on OBD-II. it's a 2 min swap between PFC and stock ecu. then wait a week or two and then go pass your smog test.

GReddy E-manage or Spilt Second is proven and clearly superior to JET, considering the method of operation/flexibility and also the similar price range.

Sure try it to be different. I wish I had money to burn just for the cause of being "different".

No SLVCELI did not get served. Quite the opposite in fact. You served yourself. What's the saying? oh yes: "Birds of feather flock together."

Nah, not serving anyone, just speaking on past experience with chip producers. The three big companies that do ROM upgrades are Superchips, Jet and Hypermotive. There are a couple other smaller comanies out there however, like Diablosport, that also make some decent ROM upgrades.

Far as I know, JET is the only company that can upgrade our factory ECUs. Superchips mostly does domestics, and Hypermotive has moved on to making Power Programmers (a tool that let's you program the factory ECU, similar to a datalogit, too bad they can't make one for our cars).

Diablosport may be able to upgrade our ECU's as well, but as far as I know, they haven't done anything with the ZZ family yet.

not really QT, there was no servage to myself, He indeed gave a good rebuttal to slvcelis remark, which was not entirely thought out first. So really...he still served him..and this thread should end anyways...
