dunno if you need any of these in the dataviewer or not, but here...


IS - Injector Slope
PE - Power Enrichment
FT - Fuel Trim (i see you already have the LT and ST)
COT - Catalytic Over Temp (protection)
TB - throttle body
CTP - Commanded Throttle Position
KR - Knock Retard
IAT - Intake Air Temperature

Really? Do you work on cars or something? You know alot about vehicle tuning. Seems like a FT job.

hahaha.. I agree, it does seem like a full time jobs sometimes... :lol:

but nope... this is my 2nd job - been doing it for just about 5 years now... it's my "hobby"... ok, so maybe I'm a little more obsessed with it than most hobbyists :lol:

hey, Kind of super old thread. if it matters 2016 f150 2.7l eb

on the trinity 2...

Des Boost

Lambda B1

Lambda CMmd


Thanks :crashing:

Boost Abs this is actual boost at the manifold

Des Boost this is how much boost the pcm is asking for.

Lambda B1 this is actual Air/Fuel ratio at bank 1 wideband

Lambda CMmd this is the AFR the pcm is commanding
