CLOSED LOOP Fuel Control using $12P
454 cu in/7.4L 4L80-E ECM = US 165 US TCM.
1 Bar Map MAP A and B flags unchecked.
Heated O2 - Denso - Flex set up to enable htr RPM vs Temp
No NVRAM. Using APU1 and/or PROM attempted for C Loop
Beginning cal was 5.7L posted with changes in VE, cold, Spark ect.
Wiring correct / Grd measured with DVOM from Bat N(earth) to ECM Earth back probe & engine running.
No Wideband functional at ECM yet. Wideband connected to pin @ ECM but Innovate controller not set up. ADX WB reads 7.30 and back probe ECM Pin = 6.3 V KeyOn, Eng stopped, heater ran 5 min on WB. (Brown wire from AF cntrl. Innovate WB gauge functional and recal done. Working well.)
No DTC/Codes set
The BLM/INT remain at 128. Same with STFT/LTFT.
Coolant temp at 90 C - C/L temp cal = 44 C
VE Learn Flag set On or OFF will not allow Closed Loop & Learn Control
Wide Band Learn Cntrl Flag is not set/unchecked
Have road speed on 1 hour drive
O2 threshold cals @ 0.40 low / 0.60 hi Volts
Can move fueling with VE Table MAP A.
O2 Ready flag = SET
O2 cross counts 1 to 7 or so. Higher on drive at steady TPS & Load when VE closer to 14.1, My Stoich = 14.1 - 10-14% Ethanol in Petrol here
Data reads:
LEARN CONTROL = Disabled
Closed Loop = Open
Closed Loop Idle = Set
BLM and INT read 128 with no movement. (STFT & LTFT same)
Innovate AF Gu reads 14.1 to 15.2 or where VE is moved. VE change tracks on O2 Volts and AF Gu.
Can use Mode 4 control to Force Closed Loop and Closed Loop will = Closed - Learn control = disabled. BLM & INT always at 128. (Force Closed Loop is not in the $12P ADX zip file. Added and other M-4 cntrls)
Is "Closed Loop" for fuel control/Trim as US OEM calibration? Modifying BLM/INT.
What am I missing to gain Closed Loop Fuel control?
I take it that Closed Loop Idle for spark control for idle stabilization vs IAC?
