    Default Tuning RAFIG and RAFPN NEED HELP PLEASE

    Well I'am a noob when it comes to tuning. I read the RAFIG and RAFPN how to's. My log file is included, after logging I don't know what to do. Meaning if my map says -.35 at 90 degrees F, I dont know how to translate that into adjusting the tuning file. By the way I'am running a roadrunner and I know my datat is lbs/min. Reason for this is that This is how my tunning software is showing the data. I converted everything to imperial. Please if anyone can help thanks.

    I believe there is a complete tutorial or thread of RAFIG. Since the tune files are normally logging in g/s would really help.

    http:////forum.efilive.com/showthread.php?t=4661&highlight=RAFIG

    That might get you straight on what pids, units, etc. I think you need logging your Short and Long-term Idle Trims vs ECT.

    I saw that thread already. All I did different was use lbs min. Idont see whats the big issue with using this. If I have to subtact or add in my tune file it will be in lbs min and not gms. Isnt the only difference the amount? since lbs and gms are diff. But the same concept. I need to know how you guys get the # to adjust in the tune file.

    I would PM Joecar, or wait until he reads the thread.

    He can explain in one or two sentences on how to get you straight.

    I believe I just selected metric units for RAFIG and logged ECT vs the Short and Long Term Idle Trims.

    ok i converted this is what i get this is the RAFPN MAP

    90 degrees F -.02 lbs/min = -0.151197
    111 degrees F -.47 lbs/min = -3.561
    133 degrees F -.59 lbs/min = -4.451843
    154 degrees F -.59 lbs/min = -4.135288
    176 degrees F -.52 lbs/min = -3.943789
    198 degrees F -.49 lbs/min = -3.678430
    219 degrees F -.45 lbs/min = -3.366041 (on this one the fans came on, i kept on recording for about 3mins more after they were on.)

    do the negs mean subtract that much?
    so if in my tune file reads as follows below(note i converted them to grms/sec already)
    this is the park and neutra RAFPN TABLE


    90 20.320939
    111 18.650207 do i have to subtract 3.561?
    133 17.070193 do i have to subtract -4.451843?
    154 15.709416
    176 14.658594
    198 13.978205
    219 13.607771


    is this how it works?

    another question when i log RAFIG do i have to put the car in gear? common sense would say yes since this is IN GEAR lol . Just let meknow if this is correct in putting into gear? Thanks again

    Here's what I use: http://www.onlineconversion.com/

    Goto Flowrate and then to Flowrate [mass].

    I'm not very practiced on RAFIG... I can't easily visualize the tables, I need to spend more time practicing (heads/cam will soon speed up my learning).

    I would use the same units as in SSpdDmon's tutorial (metric g/s for any flowrate)...

    Be sure your scantool (Data tab) and tunetool are using the same flowrate units and MAP units, and do the tutorial over again.

    ok back to adding and subtracting from the tables. if it says -4.45 for 133 degrees, does this mean this is what i subtract from the desired idle airflow for the PN position at 133?
