[QUOTE="JJackson515, post: 16688651, member: 170755"] There is a lot of misinformation in this post / thread. The E41 Duramax ECM is completely different than the powerstroke, and cummins ecm. The E41 has sha-256bit encryption on it which is impossible to crack, unless you have the seed key from GM (this is similar to the c8, which has GM global B on it). So hptuners removes the micro on it, places their own on it with their own bootloader. Updating one module, does not require every module update, as a IMMO relearn needs done with tuning the new duramax trucks for the anti theft and remote start to work. The Can bus on the new duramax is unique as there are only a few other like it (2.8L duramax, c7 zr1). The flash protocol for the 22 cummins has not be released by any company yet, it should be soon. It can be flashed with a mm3 tool connected to the obdII port and J port. Super easy. The newer trucks consume an incredible amount of def, compared to older trucks. tuning only will not fix this. Typically a bump in power is a by product of getting rid of parts, optimizing the trucks potential, and not needing so many injection events (which burns fuel). OP: Feel free to PM me if you want more information. [/QUOTE]
