Im getting ready to order a Tune from Jesse (Wait4Me) and have read on here that Crank Re-Learn is necessary?
1. Can someone shed some light on what this exactly means?
2. When is a Crank Re-Learn Necessary?
3. Why is this necessary?
4. Am I going to have to get it done if I get a new PCM from Jesse??

Thanks guys, I know someone can explain it to me.

1. The PCM needs to learn the position of the crank so that it can detect problems correctly.

2. Anytime you put in a non stock PCM.

3. See #1

4. If you have ordered a new PCM = Yes. If you had your pcm retuned = No.

I would highly suggest you get a custom dyno or street tune instead of a Mail Order!

Thanks.
Around these parts its almost impossible to find someone that does a dyno tune or a street tune. i would love to get one but for $158 i think its hard to beat jesse's tune. and i payed $260 for my hypercrapper. so if i could sell it and get jesse's i would be doin better IMO.?

Thanks for the input!!

Would NOT doing this make the Security Light come on?

Not the security light, but more than likely the check engine lt will come on.

I just did 4 computers from Jesse and none needed the relearn. They are well worth the money. It is possible and some do but not all.

I agree, there is more to be gained by doing this than a mail order tune can give ya.

With the proper tuning software or a scan tool that has the capability to do it, such as the GM TechII.
