97 case relearn?
97 5.7 k1500, will I have to do a case relearn since I rebuilt the engine and had everything apart? If so is there a way to do it without a scanner? I read about this but its as clear as mud to me as to which years you have to do 1 on, I know the newer ls engines you have to but what about the obs? thanks in advance, getting ready to maybe finish this thing this weekend.

Re: 97 case relearn?
No if you did not change the PCM, you will not have to relearn.
You will have to do a cam offset retard adjustment and it does require a real time data scanner. You could have a dealer do it. Here's the service manual page on how to do it http://carphotos3.cardomain.com/imag...3430_large.jpg |

Re: 97 case relearn?
thanks speedy, I got the cam retard set, for those of you that don't know the new c-reader model ???123 has the live stream data that has the cmp retard, this scanner is about $300 off the tool truck, I know for awhile the only ones that would do it were the gm tech2 and snapon big scanner but this handheld c-reader will do it also.
