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...

HP Tuners doesn’t update vehicle calibrations it will use on your vehicle, it uses whatever calibration was in the vehicle when the calibration was read with the software. That’s Chrysler or in the...

basically all it's doing is looking at some configuration settings, throttle angle, turbine speed, current gear, current TCC state, TCC state request, it scans through the tables till it finds a...

here's code out of a 2018 68RFE

void FUN_003bbee0(void)

{
undefined uVar1;
byte bVar2;

bVar2 = GENFGA;
if (((~bVar2 & 1) == 0) && (bVar2 = DAT_600024e0, (bVar2 & 1) == 0)) {

Chrysler does weird things with table lookup and stuff too compared to how Cummins does it

The only real resources out there I’ve found for tutorials is for shit like Nintendo gameboy game mods and stuff, not of any real help. It’s kind of a figure it out on your own kinda thing. ...

I’ll share some code for tcc lockup later

Need to learn PowerPC to really begin to understand what’s in the ECM’s and TCM’s on these trucks

Pretty challenging to incorporate TCC schedules in an excel sheet because on these things it’s based on turbine speed and throttle angle and slip that occurs is difficult to account for, ends up...

HO tuner software updates just include access to new parameter definitions for many many many vehicles, if it tells you there are updated definitions when you open your tune file and to update for...

Me either when it came to industrial injection

I’ve heard horror stories of piss poor quality control at industrial injection, their injector pumps full of metal shavings and filings, myself I’ve made better and cleaner power off of a slightly...

Lol unfortunately

My 2012 68RFE has well over 3000 parameters on the transmission end of the calibration

If you don’t know what you are looking at it could potentially be a dangerous rabbit hole lol. That xdf file contains some configuration bits for shift scheduling and lockup that isn’t mapped by hp...

Enjoy.

I'll share a user defined parameter file here shortly for that power wagon tune file

some instruction sets aren't getting recognized either leaving many functions in the code incomplete and unviewable.

One thing suppose could be done is full parameter mapping between a 65RFE and 66RFE and see what’s set differently as far as parameters go but it would be more challenging without pulling data from...

Same deal, lots of code modifications would need to be made to make that work in a different calibration. One key difference I notice between the transmission code in these gas calibrations the...

Struggle to keep bills paid is a harsh reality for real. I’ll take a peak at it this evening sometime, due to the nature of how things are structured within the coding of these things I would expect...

Anti tune theft. Highly unlikely of you did track down the original tuner of what is in the ecm will they just give it away unlocked. Businesses bread and butter we are talking there. If wanting...

Your injectors are leaking into the cylinders I’m willing to bet. First step, send back the industrial injection parts, second step buy good parts from S&S, step three redo installation

Just a few irons in the fire lol. Some have been on hiatus for like a year as I just didn’t have the time at all for them. Now I do kinda have some time I can put towards things I put on pause. ...

with enough time i could analyze it all deeper and whatnot but it would take me awhile to get to and to get through. At later time. I got other stuff on the go I'm trying to pile through and can...
