Has anyone had problems doing the crank relearn on an Ls1 with v6 efi live. We connected and went thru the steps and the fuel cut off will not come on after 4000 rpms to complete the relearn. We went as far as putting the stock tune back in the car and still will not complete the relearn.
Thanks in advance for any help.

Versions as late as 6.2.x had problems with that,
supposedly this was fixed, you have the latest?
They're supposed to be releasing 6.3.4, a clean
(non-"beta") version, around this weekend.

Thanks for the reply. we have v 6.3.3 and we also tried it with a tech2 and it wouldnt take,I dont know if that had to do with a altered edit tune in it because the rev limiter was raised to 7000 rpms and with the tech 2 you have to hold it wot till fuel cut off and we didnt want to rev that high on a new motor.

One other thing, I read a little note somewhere about
how, if there are uncleared DTCs, the crank relearn
won't run. Have you checked/cleared them out? I
had my car refuse to learn, had to get the dealer to
do it, they ended up replacing some fuel tank pressure
sensor that they said was giving a code (though all
my Predator would show, was the crankshaft position
not learned code).
