IACV resistor value, Auto to manual.

Post by **DaveyBa8** » Fri Jan 14, 2022 10:11 am

Been along time! My prelude is long gone but I have a question to ask for a mate.

Basically he has a 5th gen Sir Auto that has been converted to manual. I'm sure the whole engine and box has been replaced. Its left a mess of wires. Basically it has a 3 pin IACV and he has the loom for a 2 pin. Instead of connecting up a 2 pin IACV (which we don't have) and not plumbing it in. Is there a resistor value I can pin the plug with that will fool the ECU?. Also we are going to look at the Auto ECU and see if we can swap the 2 resistors over on the ECU to fool the car that its not auto.

Thanks lads in advance.

Argh that car sounds like a bit of a nightmare puzzle to pull together...

Would it really not just be easier to get hold of a used 2-pin IACV and just fit that?
