Do I need a Remap?? - 6G Celicas Forums

Topic #61967 2 posts Started by Rav4Race
Hi all. I have just swapped in a 3S-GTE (st-205) engine into my car. I got the whole engine with its ECU, wiring, gearbox, rear diff etc...
Ive heard that i need to do a remapping...Is it true? Have I lost power?
plz help
As long as you use the ECU supplied with the engine, providing it's the correct one, you will not lose any power, unless you're going to run it on anything but the highest octane petrol you can.

HTH
