AutoVE filter

[Gelf VXR]

I recently discovered a great additional filter for logs when doing AutoVE.

Log Fuel Trim Cell Number, if you exlude values 16 and above which are for idle, deceleration, dfco and other ??? conditions, leaving just on the gas values.

BEN values become very stable, I also filter engine temp <85 and >95, LC-1 sensor state values not = 1 and ETCTP CHANGING > 5%.


Sensor status values

0 "Unknown" "Unknown - possibly not connected"
1 "Lambda" "Valid Lambda and AFR data"
2 "%O2" "Free air detected"
3 "Cal" "Calibration in progress"
4 "NoCal" "Calibration required"
5 "Warmup" "Warming up"
6 "HCal" "Heater Calibration"
7 "Error" "Error"

EXT.WO2ST1 is a good PID to filter for RTACS so is RPM less than 400.
Filtering out a narrow range of ETC is also helpful, 5°F+/- of average is my target.
I personally wouldn't waste a precious channel on FTC but to each their own.

Some of us h ave found that DFCO doesn't show up in FTC21 or in STATE05.
