Celica Forums General Discussion Engine and Performance AEM EMS4 7th Gen Auto

I found this on MonkeyWrenchRacing and it seems that the map they have for this one product works for the 2000 Toyota Celica GTS automatic. Is the AEM EMS4 Standalone able to keep the tune from anybodys experience? This might be the first step to a possible method of modding an auto 7th gen 2zz. Here is the product link AEM EMS4 Standalone+Wiring [monkeywrenchracing.com] costs 1350. If anybody has tried this already or has experience and knows it doesn't work please comment here. If nobody has I might try the route and get a professional tuner for this.

Edit: The only things I've got done in my car performance wise is a custom exhaust system and a short ram intake+fresh lift bolts+tune up
