The AIH will set a soft code becuse the PCM is looking for it and it's obviously not there. I have been running a PMT1 for a year on my truck with great results.

 

Thanks! And the reason i ask is because that wont fly with the smog testing they are starting in CA. Thats what i wanted to know though. But i guess to get past that it would be easy enough to keep the stock PCM and swap it in for the testing. Does it matter if you have the stock PCM or PMT1 if you put a chip on it? Would there still be a difference between the two once its chipped?

 

I am sure you could build a fooler to make it think there is one there.

 

According to this diagram, pins 3 and 98 go from the PCM to the relay. I bet you could play around with a variable resister hooked to those pins and make the code disappear.

 

I am sick of Cali... LOL

Thanks for the Diagram Arisley, really appreciated!!! If I do get to mess with this E99, it wont be for a month or so. If I do and find anything, i will definitly be sure to share.
