Hi,
We have a problems with EFILive on a Chevrolet Silverado Duramax (LMM) 2500HD 2008. The truck is not drivable due to fault codes set by the ECM after the transmission pressures (TAP) exceed factory values.
The truck was upgraded with EFILive a few years ago. Autocal V2 with +40 to +100hp maps is installed and locked by a local tuner.
We have requested the stock file from the tuner as well as assistance with the problem, but he shows little interest in helping us.
When we run a live recording and diagnosis using our Autel MS 908 pro, we see that fault codes P0756 and P0848 are caused by the pressure over the shift solenoid 1-2 exceeding the standard limits of 0-510kpa (TAP), which is normal when tuning the engine.
Exceeding the TAP-values will normally generate a fault signal to the ECM but with EFILive installed it, as we understand, should "block" further activation of the MIL function.
We can not get the stock file from the tuner and not able to access and edit any values in the installed tune for ther ECM or the TCM and now we don
