what are the chances of lucking out of doing this? 75 out of 100 dont need to do this?

 

my ses light didnt come on whth my w4me tune. till after teh third time I let someone else try it, then tried to start my truck with his PCM. But it did seem to run better after the relearn. BTW I dont know the percentage that get the ses light

 

Not to ***** the post but does Hp tuners software do a crank relearn?
I've been contemplating getting it anyway.

 

Brian @ PCMforless.com said that 1 out of 20 need it..

I need to get mine done..

We logged my truck with HPtuners and it was reading 8 degrees of timing... and Brian said he had it set at 16.8* of timing....

I havent figured out where to get mine done yet either..

I guess I will try the GM guy thing.....

thanks

 

isn't there some kind of procedure that would do the same trick...like disconnect your battery for 24hrs or something?
otherwise, good luck.

 

HPTuners Scanner VCM Control will do a CASE relearn.

 

i just got mine and i have to do this too. all the places i've been want a hour of labor 70$ to do it. wont the dealer void your warranty because you have an aftermarket pcm if you have them do it?

 

guess I got lucky... I just got my crank relearn done about half an hour ago... took about five minutes... didnt get charged a dime. Went to a local performance shop... same guy i had do my exhaust a while back. I'd suggest just calling around to some local performance shops and see what you can find... gotta be someone out there in your area that wont rip you off

 

do you know what scanner they used to do your relearn? Was it a tech 2 or something else?

 

Thats weird because every Nelson tuned PCM I've put in needed it done, including the one that is giving me an SES now. I think I'm on the fourth one now since the turbo install.
