Celica Forums General Discussion Engine and Performance Will 2zz injectors work in a 1zz with stock a ecu

Hi iv only just joined but have been using this site all the time for your expert knowledge on these cars.

My question is I don't want to spend so much money on a power fc ecu upgrade and keep using the stock ecu. So can the stock ecu cope with 2zz injectors as it should be under 20% increase with the spray amount or will it just be far to Rich. Some one has no doubt coverd this before but can't seem to find the answer.

Thanks

Did you make the swap of the injectors? I want to do the same and have the same doubt.
