Forgive me if this has been covered, or if it works and I just don't know how to make it function, but...
I use HP Tuners for tuning GM gas vehicles, mainly my other truck. However, when I first bought my 02 LB7 Duramax and I still had version 2.24, my VCM Scanner would show me commanded vs. actual rail pressure, injector balance rates, and a few other key readings that are VERY helpful in diagnosing issues. I've been hoping that with every update something would get fixed, alas, that's not been the case. I just updated to 3.2.105 and still nothing. Now, it IS tuned with EFI Live, but that shouldn't matter if I'm just looking to use the Scanner function...it obviously won't read or write a tune locked ECM written with another software though.
So, is the case just me not knowing how to make these functions work properly or are they actually not supported? I figured it would be better to ask on the forums first rather than bothering Tech Support.
Thanks!
