Questions about interpreting LTRIM & O2 data in Atap
1) When you look at your Ltrim data in Atap should you only look at full cells 1 thru 19? or should you also look at fuel cell 0?
2} When monitoring the O2 readings to tune at WOT do you only look at data when the TPS = 100? Or should you also make sure the fuel cell = 22?
Periodically I get TPS = 100 and fuel cell = 13 for an )2 value.
Thanks,
Jim

Re: Questions about interpreting LTRIM & O2 data in Atap
0-15 are part throttle cells.
16 is idle in park AC on
17 is idle in park AC off
18 is idle in gear AC on
19 is idle in gear AC off
20 is idle in open loop
21 is coast down
22 is wide open throttle
just my observations.

4 - 16 are the one's to monitor on a '01 or newer LS1.
18 A/C on at idle stop.
19 A/C off at idle stop.
22 still WOT though

You can get a 22 cell reading out of 100% TPS if you're shifting an M6.
