Given up hope with my 97 uk turbo today! Went to put the prodrive ecu in and it ran but with a big fat CEL right from startup, code 24 idle speed malfunction, and a lumpy idle, clearly it wasnt operating the valve. This particular ecu is new to me but looks exactly the same as others I have seen. Luckily I have an understanding dealership who gives me free select monitor time otherwise I would be well hacked off. My question is are there different types of isv around the 97/98 years, or do you think my ecu is fried? All electrical connections were fine as far as I could tell. I think the ecu is a 98 and my car is a 97, does anyone know if thats the cause? I cant figure it out at the moment. The isv is fine BTW and is now running perfect back on old 8S ecu. Its a complete ****, a diy PPP shouldnt be this hard surely!

 

Arent ecu's from that era key coded?

 

yeah that why it was on the select monitor, to initialise the ecu and recode the keys. I am sure it should have worked so its either a bad connection or damaged ecu I reckon. Complete ****, I hate all this key recoding tosh, why with all the genius that resides within the subaru community does nobody know a way around that pesky immobiliser. Are we really saying it cant be beat! I can't really check for poor connections as I now don't have any keys to start the car on that ecu as I had them coded back to the working one. On the lookout for a simtek or pfc in earnest now, fed up with all this fannying about wasting my friendly dealers time.
