hey guys. I am trying to get into the VCM of an 09 LMM Duramax. having issues reading the VCM/TCM. It scans complete, but when it gets to the "Validating Integrity" it says it fails?

is there an update/beta patch available to support the new trucks?

I may have made a mistake by intalling the exhaust first(+3 sensors from the exhaust). THEN, I attempted to tune it. does this make a difference?

I performed the exact same task (exh then tune) on my father's 07.5 LMM and had no issues? so...???

what's going on here?

UPDATE:

turns out Hptuners 2.22 doesn't support 09 LMM Duramax trucks.

thought i would let you all know, foranyone having issues tuning LMM Duramax trucks (07.5-up) consult support@hptuners.com with your VCM suite Info and log and they will give you a Version 2.23 beta software that will fix all the issues. (disclaimer:with any beta, there will be some minor bugs)


PM me or post here if you have questions about trouble tuning your LMM.

Hptuners 2.23 is an great upgrade to 2.22.

Thats great to hear that you were able to release something within a few days of us, yes our read times should be in the 2-4 minute range for them.

I Love the hpt... I just wish we had the switchable tune deal
