No current DTC's (there are some permanent DTC's I cannot clear) , DTC settings changed to mirror GMPP LT crate motor calibration settings.
I did just recently compare all the DTC settings to a manual trans GMPP cal and mirror those settings. This made no improvement in the drivability.
@kras007 , can you provide an update on this topic, were you successful ? I have the same setup and am looking for manual gearbox OS options.
Curious if anyone ever resolved this issue, same situation, rock crawler , TH350, no speed sensor. Initially it behaved the same as OP described , would start and idle occasionally ok, throttle would...
Hello, I've had no luck trying to get the torque control to work as desired on a 2014 LV3 using a E92 controller installed in an off road buggy with a non-electronic controlled transmission. Yes,...
Please check your PM's.
Looking at your log and tune here is my suggestions to start with:
1. Change your log template to remove: battery volts, desired charging voltage, mil, add: vehicle speed, tps voltage, nv ratio if...
So, I realize you have been around in circles but start with the basics. It may not fix your drivability issues but if your minimum air flow is too low it certainly won?t help. You are looking for a...
Have you and how have you set you base or minimum air flow ?

Idle error vs. steps, i.e. target idle = 800 , actual idle = 880, ecu will subtract 8 steps from the iac. In this function the left column is idle speed error, the right column is the amount of steps...
Idle error vs. steps.
They all vary, saying it?s a stroker does not really help. Stoker combination, deck height, fuel, CR, cam timing, cam specs , etc.. My general experience on mild stroker is that they often need less...
If you need help please PM me, I can help you with this.
Because they did not have Sentry key, they had VTA.
Magnum engines had chronic issues with spark knock due to carbon deposits in the combustion chamber as well as from the actual burning of oil vapors due to the plenum gasket failing. Chrysler?s fix...
If your computer has four connector locations it is NGC, three = JTEC
You only made changes to the last load column in the fuel map, there are no changes in the area that the engine actually runs in.

The pulse width should directly translate to what you put in the map. Basically under normal (idle and light throttle) conditions injector pulse-width = fuel table + battery offset + injector...
Default baro and min valid baro.
jasond29, I have to disagree with your last post. Certainly if you are satisfied with your end result that's fine. I only want to clarify this point so that other people are not confused or...
It learns baro at key on and then relearns when map exceeds baro or if you are going down in altitude, past a specific throttle angle. Problem is, this only works with a one bar map sensor. You will...
Although that student workbook is full of a lot of useful information and insights into the operation of the JTEC engine controller, the block diagram is definitely not good information . This...
Maybe HPT can add TORR as the native unit for map as well.
