2. DPF temperature. I assume this is a sensor internal to the DPF. It will read higher than the EGT under light loads when a Regen is in process, otherwise it reads lower than EGT and reacts slower.
3. CAT temperature. This is from a sensor in the catalytic converter and is the slowest to react. It will read nearly the same as DPF under regen but otherwise is the lowest of the 3 sensors since it is farthest from the manifold.
awesome, yeah it's freaky seeing the EGT number spike up to 1300 at times then immediately drop to 500. I'm guessing it's the temp of the air passing through, but I sure hope the metals surrounding the area can consistently deal with such huge sweeps in temps.
do you know what the max boost is on our cars? can't seem to find data on that. I've seen it go as high as 19 so far.
too much data and not enough information can be just as dangerous! LOL
