picked up a p28 last week with s300 already installed. finally picked up my laptop yesterday load up my map turn the car on get a code 14 almost instantly and car idles at low 550 450 rpm.target rpm is set at 850 I adjust the slider either way and I get no reaction from the iacv. im thinking the p28 iac drivers are toasted and the guy that sold me the p28 failed to mention it.


my reasoning for it is cause I plug in my p72 car runs fine idles fine. I tried to upload to a different map to the s300 and it does the same thing code 14 and rough low idle. im getting ready to order another s300 ready ecu from ha motorsports but before I spend the money I want to make sure infact the ecu is bad and not the s300 that is bad.


any thoughts??

Go in the sensors tab and see if the iac is working and see if any where in the settings f it has been disabled ... If not then u may have to buy the other Ecu

 

I looked thru the sensors tab and didn't see iacv count at all.
and in the idle tab its enabled.

 

bad p28 was the culprit. just thought I would add that to this for future reference.
