    DTC descriptions (LNF)

    I'm trying to adjust the DTCs on an TC SS cobalt. We are running a highflow cat and it's tripping the O2 codes, unlike all the LSx/L67/4.3 etc. I've tuned, the DTCs are totally different (i'm used to three options here there are over 12). Is there a descriptive anywhere explaining what each one does? I've tried three different options now......without results.

    My help section in HPT only shows the three usual ones - as I'm used to - and does not show these new ones.
