One question. Do you need change ECU from automatic to manual after swap manual tranny in to the ST Celica? I did not do that. No problems with that, but when I try take off really fast, it will drop rpm and lose a power for a split second and I have to play with a clutch get it roll. I thing that is a ECU problem. What do you guys think????

when you let the clutch out the RPMs drop a few hundred and you have to compensate for it using the gas pedal. thats just what happens with manual transmissions.

maybe I'm just not reading your question right?

I know that. It is something with the car. I just gonna change a ECU and will see.

how did you wire your auto ECU? you didn't get a CEL?

I used a m/t ECU from a 96. different part number but works fine.
