Ive been doing tons of research over the last few weeks on how to tune my truck like those guys on EFI live do it but through the hardware i already own with HP tuners. It seems that in the repository someone uploaded a DSP4 tune (switchable between 4 tunes on the fly) for a 2016 colorado. same engine and vcm as the canyon and ive been combing through the file to get information as to what is different from a standard one position tune. I cant seem to find it.
First off, how does a DSP4 switch work? Do you have to flash the computer for each setpoint? like the stock tune flashed when knob on the 1 position and a tow when knob in the 2 position so that it remembers what tune you set the knob in for later... or is it all within the E98 and this knob just tells it to view some different tables. not alot of info out there on this
secondly how do i write these tunes then if it just recognizes different tables which ones and how do i tell the ECU what to read and when.
I attached a stock so if your curious we can review them but dont want to put the DSP4 one on here so we keep from my thread being deleted
FYI im talking about the diesel here not a v6 gaser
Thanks!
