Hi guys,
I gut a really simple question that I still can't seem to figure out: How do I set idle to Open Loop in TunerPro? With the one switch I found (Min Temperature for Closed Loop) I am unsure whether it only affects Idle Mode...

Grateful for any pointers!

This may take some trial and error but you could start by comparing these values from the ASDU disassembly with your calibration:


; OPEN LOOP IDLE CALIBRATIONS
; L05
;
;----------------------------------------------
LD29E FCB 4 ; 4 MPH, OPN LP IDLE THRESH
LD29F FCB 5 ; 2%, OPN LP IDLE THRESH TPS
LD2A0 FCB 1 ; 25 RPM, Open loop RPM thresh IDLE OFF
LD2A1 FCB 2 ; 50 RPM, Open loop RPM thresh IDLE ON
LD2A2 FCB 160 ; 8 Sec's, Open loop IDLE AFR Ratio enable TIME DELAY
LD2A3 FCB 100 ; 5 Sec's, Open loop IDLE AFR Ratio TIME DELAY
LD2A4 FCB 137 ; 13.7 Open loop AFR MAX AT IDLE
