Cm2200 bricked from just reading ecu?

[JtRenegade]

Is this the only model that has this issue?

I ask because I have a 2009 Ram 2500 6.7 with an unknown "tune" on it and I'd like to check it out if I could.

Don’t know, don’t have much in the way of experience on the 07.5-09 Cummins, 2010 and up it’s a definite yes you will run into the same thing. If it’s a locked tune or a tune that has a changed OS number then you could possibly run into issues

well, as many of you found out to late.....dont try to read a 2010and up dodge diesel......50% read and it freezes the ecu. turns out this is an epidemic, its happening constantly. now i have to pull the ecu and take it to the local performance diesel shop to have it reflashed. ( truck is to far away for tech to come there ) so, who pays for this? me i guess. why is this so maddening? because hp knows about this, and yet they just sit back and let there customers plug in knowing its going to brick it..... i am so mad. so unprofessional, all they had to do was take those trucks off the vehicle supported list till they figure it out. but no..

yes there are read issues with HP Tuners and a cummins ecm with stock calibration on it that needs to be addressed but for those attempting to read tunes and delete tunes that have been flashed to the ecm by another device like EFILive, MM3/RaceME, H&S, etc etc, not HP Tuners fault at all and its naive to think that to get others work, especially emissions deleted work is just as simple as reading with HP Tuners. The MADS products, the Smarty, MM3 and RaceME have got their stuff together to prevent being read/hacked, EFILive is meh in that department but if an EFILive CSP tune is written to the ecm, there is a specific change that gets made that will cause the failure of being read with HP Tuners. H&S, well that's just Bullydog trash that uses Brazilian specific calibrations that no one else uses and causes all sorts of issues besides read fails from HP Tuners. The only product I know that can and will automatically restore an ecm on a write fail is the MADS products. HP Tuners the ecms get stuck in bootloader and will no longer communicate to the HP Tuners device and I have seen completely destroyed ecm's from HP Tuners, somehow corrupted bootloaders and i know I'm not the only person to come across that. EFILive has a greater chance of recovery same with Witech.

Ultimately, do research first and weigh your options and accept that in the end it's your responsibility if you decide to use a product, this thread here is far from the first over failed reads/writes for the 2010+ Cummins

We had a similar experience last night when trying to read a Dodge Ram 2012 last night. Tried to read the ECU to save a the stock tune it the VCM suite aborted/timed out during the read. After the time out, the truck would not start. We first thought we bricked the truck, but when we looked closer, we found that the anti theft immobilize light was flashing and the radio was asking for a security code. From this, it looks like the anti theft was triggered during the read. Could this be the real problem that everyone is having while trying to read the ECUs? I confirmed with a Dodge mechanic that it was in fact in anti theft and it might need a reflash to get it out of immobilize mode.

I'm new to using HP tuners product, but I'm a bit concerned now that this happened and many others are too it seems. So in my mind, I'm asking myself, Did I make the right choice in this hp tuner investment? (Rhetorical, don't need a response). I did do the research before because I am very cautions and did see that others had this problem, but because everyone was blaming it on already tuned ecu by another tuner. So my conclusion is that I would not have a problem because it was a stock OEM tune. We live and we learn, sometimes the hard way. My intent to post this is to share my experience on what happened to me and that maybe HP tuners will look at this problem differently.

Luckily, I found a stock tune in the forums and did a write and the truck fired right up. I would have like to the original stock tune, but right now I'm glad to have a running truck.

That’s an extremely rare case, 99% of the time the ECM’s are stuck in rom boot mode and require a recovery flash that cannot be done with HP Tuners. Generally it is caused by trying to read an ECM that has tuning in it from a different tuning device. Could go into the whole calibration numbers and explain how they differ when you get into the realm of EFILive SOTF tuning, etc etc but that’s boring stuff.
