I am getting these error codes when I open the vcm scanner without being plugged in too truck, idk if that is from it "loading the last tune" or if its even doing that since I have never put a tune on the truck with hptuners.

Bill,
Why not just allow us to flash in a good known base file. Put the correct VIN in, and flash in the ecm that is giving the checksum error. Problem solved...
Thanks
Sam

Where are you guys located?? I'll bring in my truck. Had a smarty on it had it reset back to stock. Couldn't read file. Had it flashed by dealer still can't read file. This sucks.
03 cummins 6 speed, spending about 40% more in fuel towing stock and have dropped a lot on tuning to get nada
They are north of Chicago, I'm in Tn, little far for me.
I'm in northwestern Ohio. I would be glad to help if I can. My ticket number is 86823 if anyone would like to email me. I could drop my truck off for a while and ride the Harley.

I'm having the exact same issue as everyone else with my 2004.5 Cummins, check sum error. What are we supposed to do??? Someone needs to resolve the issue and quit beating around the bush, $500 for a tuning suite that doesn't work is a bunch of crap.
No its been 6 weeks and still nothing, HP needs to get their you now what together. Sending mine back and getting a refund.
I have an '05 auto with the same issue. Ticket 91929, been waiting a week. How bad do you need a truck? I wouldnt be thrilled about it, but I'm under 3 hours away.
Wow... this is great news... Mine just did the same thing. I'll be on the phone with visa tomorrow.
if you guys find a friendly dealer and have your truck "reflashed" at the dealer then this has fixed all checksum errors for me, or if you know someone handy with a laptop that has INSITE then they can reflash to factory for you i think i might have an extra pcm laying around if anyone wants it to swap out
and for everyone pissed off about the tuning suite not working, just be patient, I my experience, it works on a stock-virgin-never been touched ecm, not one that has been returned to "stock"... you guys do realize the this is about the cheapest licensed tuning device available with more adjustable options than most will ever need

I've had mine reflashed by dodge, still same problem. How do you hook up insite through the dodge dlc? I've tried that it it won't connect with an inline 7 or 6. My 04.5 doesn't have the data link connector on the engine harness, and I'm pretty sure other years do not have it either.
dont you guys remember the big stink with efi live and the cummins, they still specifically say that if another tuner has ever been used then it must be reflashed by dodge first or u risk bricking the ecm, its in the user notes i think, if i find the link ill post it
With efilive you can change the vin of a known good file and flash it in though. A file that has good checksum's and such. The issue with them initially was people reading out the ecm's that were returned to stock and having checksum issues. If you start with a good known file and flash over the garbage than there isn't an issue. It would solve a lot of problems to just be able to change a vin and flash.
agreed, but how hp licenses wont let us do that
