CASE Relearn after Flash

[GMPX]

Hi All,

We have had two Diesel users now ask us about how to get the CASE re-learn to work on the Duramax, simple answer, you cannot.

The next update of EFILive will have this warning suppressed for Diesel motors, until then, please ignore it if you are tuning a Duramax.

Thanks,
Ross

what is the case relearn is it like block learn?

[GMPX]

LS1 PCM uses it for misfire diagnostics.

It is used to measure the variation in the crankshaft timing in relation to the camshaft timing. According to GM anyhow.
