    Default How To RAFIG with Speed Density?

    I'm failing!!

    I'm trying to do the RAFIG process and I'm running into trouble. Here is what my options file looks like:

    PCM, ECT, -40:110:1:1:0
    PCM, MAP
    PCM, RPM, 0:6500:2:1:0
    PCM, SPARKADV
    PCM, TP
    PCM, AFR
    PCM, KR
    PCM, IAC
    PCM, AD1
    PCM, IBPW1
    -, IAC_STD_M
    -, IAC_LTD_M
    -, DYNCYLAIR_M
    -, DYNAIR
    -, CALC.BEN_LC11
    -, CALC.AFR_LC11

    I'm getting no data from the IAC_STD_M and IAC_LTD_M so I'm guessing they are looking for a MAF signal. Can you show me what I'm supposed to be logging the the flashscan V2?

    Along with the ECT pid you need to log the idle air trim pids.
    GM.IAC_LTD_DMA, GM.IAC_STD_DMA & CALC.RAFIG.

    going by your sig i`d say...
    IAC - Long term correction, in P/N, A/C Off {GM.IAC_LTPN_DMA}
    and
    IAC - Short term correction, in P/N, A/C Off {GM.IAC_STPN_DMA}
    and
    Idle Airflow Correction AC Off, P/N {CALC.RAFPN}

    exclude data where you are overly lean and rich.

    I was told that in the options.ini file you do not type out the _DMA just the _M and delete the GM_ part, this is what I did but doesnt work.

    I also just hooked up the laptop and recorded right from there and the 2 PIDS did NOT record any data.

    I enclosed a short log file so you can see...

    Do you have B4108 (STFT Idle) enabled?

    I believe you have to have them enabled and run the stock O2's... Cause Idle fuel trims still utilize the stock O2's to work... I run COS3, no MAF and no stock O2's... But I still have them installed and just enable the idle portion and I have no problems doing the RAFIG and RAFPN.....

    your sig says you have a 3600 stall, so i assume you have an auto trans......
    right?
    you had the in gear PIDs selected try the P/N PIDs.

    Yes, it's a powerglide trans. I'll try the P/N PIDS in the morning.

    Thanks.
