Like the title says, is anyone running a 3rd gen ECU from an MR2. according to this diagram, the MR2 has more sensors than the ST205. will I be fighting a CEL?

yup, did it on jims 3rd gen in the alltrac. IIRC the extra pins are for things like the PS and stuff, nothing critical.

^^^ Thanks Manny!!!
it looks like the 3rd gen has the same signals like the 205 for intercooler? did you have to defeat code 54 the same way? This post has been edited by Smaay: Mar 14, 2016 - 10:08 AM -------------------- 2001 Celica GT-S Turbo

good to know. i wonder why people doing third gen swaps dont seek out these ECUs?
looking at the Engine control drawing for the 1993 All-Trac and the 3rd gen SW20 pinouts. I have to change 2 pins!!!! thats it 2 pins. Move FPR pin A-6 to C-16 Move PIM pin C-5 to C-2 It cant possibly be that easy This post has been edited by Smaay: Mar 15, 2016 - 11:11 AM -------------------- 2001 Celica GT-S Turbo

the 205 has far superior intercooling, therefore can run more timing.
