I tried to read the pcm in my new truck today without success.
[2010 chev vmax 6.2 6 speed]
it would read the vin and some sectors but reported the vehicle as a 2006 and wouldn't finish the copy.
i have ver 2.22
do i need a an update???

 

Yep, 2.22 has a security issue reading/writing the 09's on up....email HPTuners support and they will send a time sensitive link to the latest beta version...I hade the same issue reading my buddies 09'..

 

thanx again.
gotta get hpt sorted out so i can turn off codes headers will set.
by the way it only took gm a short time to build and ship my truck.
built on jan 4th, delivered on 19 th
you may get yours sooner than you think

 

What codes surfaced after adding headers?

Hopefully she comes in sooner... You would think they have folks in Detroit trying to keep busy...

 

i forget the code #'s , hpt is one my laptop at work.
1120/1 1133/4 maybe
related to rear o2's and convertor flow out of range
i just set them to report no error

 

Send the guys at hptuners support an email stating you need the latest beta,Bill will get you taken care of!!

 

Thanx Charlie.
