Guessing there is still silence on the JTEC/JTEC+ issues, isn't there?

It really depends on your use. HPT is amazing on GM. My experience with Dodge has been less than ideal, but I primarily work on GM vehicles.

Don't get your hopes up, my MPVI3 effectively erased a JTEC+ PCM and the quickest solution was buying a used PCM to get the vehicle going so I could get my truck back that I had loaned them in the...

HPT as a company has liabilities in providing the functionality their devices give us. The emissions test is them covering their rear end so that they can tell the friendly employees of the...

No clue, but if the solution is paying someone else to fix the issue that HPT created, you can bet I won't be using or recommending HPT for anything but GM.

Has anyone with a no-start vehicle been able to get this to work? Mine gives a baud rate timeout and after communication with support was told to have the PCM reprogrammed elsewhere and then try HPT...

Same issue here on a 1999 Ram JTEC+. I was told after reporting it that I'd need to have it reflashed with another tool and then try using HPT again.

what I would like, is to have a working PCM at...

Bill, understood on the scramble to get things moving. No worries, appreciate the extra effort to get things fixed. I'll try to resync again later and see if the firmware pushes by then

I sent the message to support as requested, and received a reply (Ticket #70255) with instructions to update the firmware via the Beta version of VCM Suite. After following the procedure, no firmware...

Thank you for the reply, Bill! I'll get right on that.

Be careful with the MPVI3, several of the "supported vehicles" aren't actually supported, and it'll let you write your way into a dead vehicle. JTEC/JTEC+ and one of the Ford PCMs, if I recall.

This is what I see when I view it on my end.

Not sure what effect this would have or if I'm completely off base here, but your gear ratios in VCM Editor>Trans>General are set to

1st: 2.48
2nd: 1.48
3rd: 1
4th: 0.75
R: 2.08

Those are...

There are also issues with a couple Dodge and Ford PCMs with the MPVI3. I'm sure whoever handles their R&D has their hands full with all these fixes, I know of quite a few people with vehicles in...

I laughed way too hard at this.

Well that was a lot simpler than I imagined. Good catch

I spent several hours looking last night, and couldn't find anything at all anywhere on the internet. Plenty of challenger and 200 files, but nothing about the Ram. Sorry, I'll keep my eyes open

can you upload the stock file you have for review? I have a few stock files for 2003 5.3s and tach output is present in all of them.

Let me go take a look at my computer and see what I've got. Don't hold your breath

Did you get the privileges linked to the computer you're using for the scanner? You have to link it to your account here and then once generated, enter the device code in VCM Editor:...

Thanks, I think. :yay:

Good luck. It doesn't seem to be that anyone really has a good idea as to which fault class types mean what, I spent a good bit of time searching similar topics around the internet the other night.

Sorta begs the question as to just how much testing occurred BEFORE releasing the MPVI3.

I understand the process is detailed and tedious, but when we're sitting on vehicles that were stated to be...

Gosh I wish I'd have seen this earlier. Used my MPVI3 yesterday to read, make minor modifications, and then it erased and failed to re-write a 99 Ram JTEC+ resulting in a no-start situation for the...
