ECU's PLUG AND PLAY?

[2jzget]

Will the OBDI Supra auto ecu work in an OBDI auto SC300. will it work without mods to the wire harness

[Bean]

Yes, as long as the Supra auto ecu is from a nonturbo supra...

[2jzget]

Great! So it's a plug and go affair.
I have been told that Supra nonturbo auto ecu has a higher rev limiter than the sc300 auto ecu and that the programing is a bit more agressive.
I can get a Supra ecu for about $75 and would like to try it on my SC300. If nothing else I still want the higher rev limiter

[Bean]

Nah, they are the same... on my SC300 I dont hit the revlimit until 6800ish rpms... it shows up as 6400 on the tach, but on my AFC it always showed 6800

[Dramon]

wtf, my rev limit seems to be at like 6k in 1st gear and then after that at about 6200.

[Bean]

yeah but does it say that on your stock TACH or does it say that via an AFC? I think the stock tach responds slowly... When turbocharged I would frequently hit the revlimiter in 1st and sometimes in 2nd... it showed up as 6100-6200rpms on the stock tach because it got wound out fast

[Dramon]

it says about 6200-6250 on my safr.

[Bean]

I cant explain why that is. My SAFC always stated ~6800rpms on its tach and the tach itself always stated around 6200-6300
