I was messing around with the OP2 tonight and found that there are some combinations that won't allow the logger to work. Throttle position in conjunction with one of the other params (can't find it now) will not allow the log start to trigger.
There are also a few that have combinations that force the logger to record when the car is on and off. AF_Correction1 and AF_Learning1 in combo make the logger record as long as the ignition is on.
When using both MAF and MAF2 params the defogger switch start doesnt work; as well as when using both MAF Voltage and MAF params.
This is a short list of the ones I found that cause the logger to run with the ignition on.
; similar to STFT / 100
paramname = STFT_AF_Correction1
paramid = 0xFFF8A5EC
isfloat = 1
; same as LTFT / 100
paramname = LTFT_AF_Learning1
paramid = 0xFFF8A774
isfloat = 1
paramname = STFT
paramid = 0xFFF8DB74
isfloat = 1
paramname = LTFT
paramid = 0xFFF8DB78
isfloat = 1
paramname = Direct_Injector_PW
paramid = 0xFFF887E8
isfloat = 1
paramname = Direct_Injector_PW_Ram
paramid = 0xFFF887F0
isfloat = 1
*EDIT* I just realized that in previous logs I had these closer to the end and they worked just fine. When I put these to the front of the list it causes an issue.
