M43 idle control valve replacement

[reflex88]

Simple question, but I can't seem to find an answer anywhere.

When changing an idle control valve on an M43 powered car (and probably M40/42/44).. does the new valve need specifically coding/adapting to the ECU? Or, is it a learning part with out the need to tell the car it's had a new one? Just driving it will result in the ECU learning the new parameters?

Taa.

Some one must know?

To my knowledge if it's 2 pin no the car should adapt, 3 pin may need new parameters seeing as how that should signify a digitally controlled unit

I didn't have a problem on my M44- plug and play.

Hmm, it's 3 pin.

Guess it's time to research ebay cables and what software to buy.

Just look up others doing it. 3 pin could be power ground and trigger as well.

Do you have the on throttle body kind or separate tubing kind.

[reflex88]

It's the throttle body attached type.

Got some injector seals I'm gonna throw on and see it it's that.. if it's not I'll start looking at sensors... I know the o2 is ok because it reads fie at MOT time.
