Hello,
I have Idaho Rob's tunes on my 07 since 2012 and have not really had any dramas. The tunes I have from him were back in the day where everything was shipped unlocked. (Lucky for me).
Recently I had some issues with my turbo, very visible over and under boost conditions and I never threw a code for it. Finding that Odd, I dug into the tunning and found C0802 and C0804 - C0806 effectively disabled (Won't let me attach a photo)
The Error time and max/min boost times mask any conditions where the truck can't track boost. This is linked to my DSP Tables for Desired Boost Levels EGR Off Low/Mid/High command high amounts of boost (relative) @ 0-5mm3 1600+ RPM.
Target VGT and Target Boost are increased 1600+ RPM between 0-5mm3. Seems "standard" for turbo brake application in tunes.
Also inherent miss-match on boost table and VGT table, but it appears to align with B2231 on ECM Boost Control enable @ 2mm3 & 1600rpm.
If I want (I do) to return my Boost Parameters table back to stock, I see two paths forward.
1) Attempt to massage B2204 - B2206 entries to match actual boost through all elevation ranges (ick)
2) Adjust B2231 and B2232 as such ECM Boost control does turn on until after 5mm3 of fuel.
I would like input for more experience tuners on how this managed. I don't like masking errors as was done here unless the sensor or the control loop is actually disabled. (EGR, cough cough). It would of highlighted my turbo issues MUCH sooner than I found, hence my digging into this more.
Thanks!
