Best, most versatile tuner tool for crank sensor relearn?
Hi guys,
I just went ahead and ordered a new CKP sensor and will most probably require a CKP relearn procedure. I figure I will kill two birds with one stone and get myself a proper tuner/scan tool. Since the GM Tech 2 is basically out of the question due to the high cost, I am looking at the following:
EFI live
HP Tuners
I am assuming that both should be able to perform the CKP relearn without a problem, correct? Which is considered the better option for long term tuning/diagnostics possibilities? Are there any others that I should consider? Is there a cheaper option?
Thanks in advance for your comments.

I didn't need a relearn when I put my new one in. I had to replace it because the wires melted. Most Vette specialist should be able to do it with a tech 2 for 30 to 50 bucks its a 5min job if even that. By live or tuners for tuning if all you need is that I wouldn't waste the money.

I was combing the internet for CKP relearn information and came across the attached procedure. Supposedly, the CKP relearn process can be performed without needing a scantool. Has anyone ever done it on a C5? Is it applicable to our cars?

I should have included the whole document. Here it is. It's on page 4. It also contains other useful information.

Relearn is not accessible through
your scan tool (some truck
applications 1998 & later), perform
the relearn in the following
manner..
That reads to me it's for some Trucks and that's all but maybe I am wrong. Did you ever get it replaced? Why where you replacing it? Like I said when I got a new one I didn't need a relearn. But each car is different.

Yes, I just completed the job yesterday. I replaced the CKP sensor because of intermittent engine shutdowns without any codes being thrown. I've been chasing this issue down for months and went by process of elimination. There is nothing left to replace.....
Here's my post on the journey I've gone through:http://forums.corvetteforum.com/c5-t...dm-u1016h.html
Anyway, the car started right up and ran beautifully without the relearn sooooo............I'm hoping nothing pops up down the road telling me my CKP sensor is out of calibration.

It could be for trucks only but then again, I read some posts on other sites saying that it's applicable to all LS1 engines. That's why I was asking the question.

I installed a SPEC Dual disk clutch with a lightened fly wheel in my 02 ZO6. It also has a pretty big cam. After the clutch replacement, the engine idled horrible and low speed RPM under load resulted in a LOT of bucking and engine complaining.
I used the GM Tech 2 and did a case relearn and that resolved 90% of the induced issues. I think tuning will take care of the rest.
The articles are very cool. Where did you find them?? Some interesting stuff BUT,,,,,,,,,, some of the procedures are for OTHER platforms and do not cross over to C5. You have to be careful. Even I don't know what procedures can cross over. I'm not sure that case learn will work but, I also can not say that it wont.
Some early C5s (97 & 98) do not require a case learn. The early C5 also do not require a EFI Live tuning license to tune the PCM!
So, not all C5 are created equal. Its tough to keep track of all the ins and outs and differences.
