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?

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

cause the 205 has more agressive mapping, just like the 185 VS the mr2.

so the 205 ECU performs better than an MR2? interesting, i never heard of this.

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

nope sorry.
martin vernier on facebook is a reliable source for gen3/4 parts now a days. IIRC primemr2.com has em new for around 150 or so.
