just installed ottp stage 1 everything hooked up fine but car wont turn over, put old pcm in and car turns over, but wont with tuned one from ottp

 

Security light on dash light up?

 

I thought someone else just had this issue. It was the wrong year ecu i believe

 

yes security light was lite up. what can i do?????

 

try what sunburst_ss says in that link I gave you. if that doesn't work its either get in touch with ott or dealer time.

 

take put the key in turn to run wait exactly 10 mins turn off. then back to run 10 more mins. turn off turn to run 10 mins. take key out wait 1 min crank

 

u need to do the case relearn and security releearn . one is the key one which u can do your self but the other one needs to be done at the dealer as far as i know and heard

 

im a gm tech. that way should work. never let me down before

 

I wish you the best getting this taken care of! If this doesn't work contact sean/josh over at ottp and they will get it all straightened out. There good guys!

 

yes the key on for ten then off then on for ten then off then one last time worked fine. thanx so much for quick help fellas. got that done and went to install vibrant header and dp with catback and was almost done when the last section of pipe with muffler would not go over the pipe that was hanging there. gonna go back in morning and have pipe flared out and get case relearn done...

do i just tell the tech to do a case relearn and he"ll know what im talkin bout right?

 

he might just be prepared just incase. glad we could help
