Hello all i have a 2001 suburban with module P01, pulled my stock file, updated the speed density OS, did some data logging so far. Right now my fuel system #1 is at CL-fault, I am wondering if fuel system #1 and #2 on data log channels correlates to the B1 and B2 or oxygen sensors
until you post up your tune and log we cant do anything to help you at all.Quote:

you paint the picture for us to help you.
and why are you messing with SD os?
My exact question, why would the first thing you do be adding the speed density OS?
Will add log file in the morning, and I try to update all the OS before doing any tuning
Figure it’s best to keep things up to date, then again I am new to this, tuned my cummins once after an engine swap to the best of my ability now trying to learn gas :)
Some of the early SD OS's keep the MAF from ever working even if you have it setup to do so.
I think you'll see CL fault if there is a MAF failure.. which might be related to the SD OS
Changing to a COS doesn’t keep things up to date. It changes it to a different type.Quote:

I since have made a better channel list but for that first test was seeing what was available and logging
Gen 3 can only handle so many channels at one time.
