Tuning RAFIG and RAFPN NEED HELP PLEASE

[z28ls1818]

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.

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

I was referring to the above values. If that is your latest log, I meant -3 to -4 g/s is a lot (IMO).

Just puzzled by the amount of correction taking place.

I may be missing something, but I was referring to the above values. If that is your latest log, I meant -3 to -4 g/s is a lot (IMO). But, if you are getting different readings I may have missed it.

Sorry, not trying to sidetrack you. Just puzzled by the amount of correction taking place. Anybody else have a comment?

..WeathermanShawn..

well my cars tune isnt complete. mostly idle issues. this is why im trying to get the rafpn down first and the rafig. ass ssdemon says to do. then ill work on the idle dipping down to much. its funny cause right now when my idle dips down in park when the car is in operating temps, and if i play with the idle and raise the idle to 900 instead of 800 it wont dip anymore. but i dont believe this is the best way to fix this. this is why im trying ss demons writeup.
