Discussion and questions related to the course Practical Diesel Tuning
(Stock PCM)When using a tuning module, example only SCT. Are you able to modify the module software in the truck with tuning software, so that you can match it to the truck. I ask this because it seems you have a known good base tuning platform to work from, wrather than starting from a stock pcm calibration.
It's rare that modules such as SCT allow modification of the existing operating system (exception SCT's custom tuning package). In most cases the handheld programmers force upload their own preferred operating system which is often based on an older OEM release.
