[Cesarpty]

hp tuners detect protocol failed

[Cesarpty]

Could someone with a good heart help me or give me some explanation?

[LilSick]

I do not have a good heart and i have no idea maybe Jim P does?

I read all of Jim P's posts and nothing

I even sent a report to support and I'm waiting for an answer... but what I've read. about support is not encouraging in the forums. And what a coincidence that it is my first car that I want to modify and this happens

[Jim P]

Could have happened just from the instability that comes with HP Tuners. Could potentially need a bench flash to recover the ecm, hard to say. My personal advice is spend the money on a stable platform. Don?t use HP Tuners on the premise of it being low dollar cost interface, the platform really is not that great on these trucks.

HP Tunners staff contacted me. I managed to reflash the equipment to its original state with witech and it worked perfectly.. only now I read it again with hp tuners and the same problem continues as soon as it reaches 50% and dies there..

[Cesarpty]

I'm just trying to do a reading.. and it dies

[Jim P]

Yea HP Tuners sucks. Try doing a read with zero internet connection, should generate a stock file for you.

had this happen a few weeks ago on an 11even tried with newest beta. debated on not doing the key cycle it asked for but didnt want to keep trying
luckily i had a stock file for efi live flashed it and it was fine. i beleive it puts it into boot loader when it shouldnt?

[Jim P]

It needs to go into rom boot to read/write, the boot loader contains instruction sets needed to perform the read/write. The issues lie elsewhere with HP Tuners. Using EFILive to recover won?t always work. It?s hit and miss, lots of times a bench flash in rom boot with EFILive would be required.

I am going to update them.. yesterday, talking to support, they told me that I should put it on the bench and since there is the possibility that there is some problem in the wiring or that the truck was previously tuned, which I don't think so.. but hey, I'm going to do I go to the bank, what happens if I put the truck as a paper weight?

[Cesarpty]

I think that at the end of the story I am going to buy efi live for this class of pcm

[Powerstrokecustoms]

what year is this truck??

[Jim P]

Believe it says it right in the title, 2012

[Cesarpty]

2012 ram 3500.. still haven't benched it yet.. kind of tangled up with another truck

[Francuzzz]

I had the same problem with RAM 2500 6.7 diesel 2011 year, tried to read it and it died... Recovered it with witech 2.0, I have update ecu with the last software from mopar. But did not try to read it again

I've experienced this issue as well. I grabbed a bunch of bench units and tested on the latest build. Seems to be fixed. I haven't tried in the truck yet. I have one lined up next week.

Bench reading and bench flashing is not the same as when it is on the truck, issues occur on the truck, unless trying to read an EFILive CSP tune, then you?ll have issues no matter what, in that case the file will be incomplete and since HP Tuners does not use the EFILive CSP OS number, it just won?t be useable.

Have you tried with the latest beta? It returned a stock file, from a tuned truck... I also understand the bench behaved differently than a truck, but it can still be a useful tool.
