Ecu

[ilovecorollale]

I was wondering if you were to change the oem corolla ecu to the oem celica gt 00 01 02 ecu that there would be some kind of gains.If so were the years of the celica i mentioned correct but what about the celica gts...im guessing their ecu wont work?

I have read and searched somewhere but seem to lost the useful info i have read before so i wanted to ask again...something about the plugs of the celica ecu is differ from the corolla ecu...so what will i have to do then.

Have a read of this thread:

celica ecu

celica gt's are 1zzfe's. the celica gts's are 2zzge. the ecu could be tricked to work, but it would have a fit when it came time for lift to engage. the best option is the celica gt ecu. just have to swap ecu plug ends. once that is done it opens up the possibility for a power fc later on down the road. hehehe.

Well yes i know about the gt and gts but about the ecu...i have read and searched that it doesnt work at all...the car will still run but makes it even slower and have difficulties with the ecu.

I'm still trying to figure out the same thing, but I want to know it has been done and effective before I buy a celica ecu haha.

so if my car is manual then i get a manual celica ecu and if its auto then i get an auto celica ecu correct??Somehow i have looked on ebay and there are plenty but then there's a few couple that looks weird and differ.

Besides if the intake manifold and TB is from a 01 celica...is it okay if i get a 00 celica ecu or a 02 ecu?as long as it is identical right?

yes manual for manual and auto for auto. the 00-02 gt ecus are all drive by cable and to my knowledge interchange with each other, of course auto for auto and manual for manual. i think the 03-05 are drive by wire, so if someone got that by mistake i could see how the car would be slower and have problems. its looking for a servo motor that isnt there. and in the servo motor is the tps iirc.

I thought that toyota started making all the celicas 00-05 drive by wires only now and that theres no drive by cable....
