r/HPtuners

Went to flash a “race” file on my truck, 2024 GMC 2500 HD. This all went all good up until the “erasing” portion. It completed “erasing” than hard crashed. Now the truck has no file and will not start up. Every-time I try to write a file now, It says “connecting” for about 10 seconds. RTD4 controller goes from solid green to flashing yellow and crashes. I have tried deleting the app, resyncing, deleting all files and redownloading, and even plugged the controller to my desktop and resynced it there through there vcm suite… nothing is working. I even disabled all Bluetooth devices to make sure there were no issues there. I had just flashed this race tune last Friday and put it back into tow Sunday evening going into the weekdays. I need some help here, having a hard time getting in contact with my tuner and HPTuners.

Recently bought a MPVI4 and a laptop any other accessories or gadgets that are worth investing?

I’ve been working the last almost two-three months straight and have been planning to do this build the entire time from front to back. Stacking up parts throughout all the time I was working and bought a truck right after I got off for the summer. Got a borla muffler, long tube headers, chopocabra with the full head kit/ lifters, melling hp oil pump, injectors, aem wide and, and even bought hp tuners, just trying to give you scope on how deep into this I’ve gotten in a matter of weeks and not a damn thing is installled yet performance wise lmao.

Just been doing repairs to make it sound enough to throw parts at while I fix my sleep schedule, nothing engine-wise all suspension & brake stuff ( it’s a rust bucket I’ve been having to do some grinder intervention ) and I have to paint it & do body work.
Been doing literally nothing but studying the process of tuning with hp tuners inside and out from as found file to smoothing out SD for weeks (which I won’t be doing because I’m NA).

Really to encapsulate all of this I need someone experienced to tell me what order in which to do all of this in. Should I pull an as found file before I start giving it parts? How do I start it for the first time after rebuild and how quickly do I have to tune it before it sends a valve to meet the piston? It’s getting all the ones I have at once it’s really just an exhaust, cam kit, hp oil pump, wideband and full exhaust + 50 lb gm injectors. Kinda realized I’ve overwhelmed myself for my first tuning venture having so many mods I’ve added

Honestly I don’t even care what power it makes anymore I just want to put it together and see it run lol, please send hate

Edit: it’s a 2000 single cab Silverado 5.3 with 0 engine codes except for vapor purge wiring harness or something along those lines I haven’t gotten to yet

Hey yall, I got a 22’ RAM 2500 with the 6.7L, I saw lately that HP tuners have gotten past the security for the 22-24 ECM’s. Has anyone tried it out? What kits did you buy? Any advice about the products?
