How does she feel Noogles? Can you tell a difference? I would think 22 degrees timing would be a lil much on pump gas but if you are not seeing any knock thats great.

I agree as well. If Colby, Jason, and the bunch arent charging for the program that they've dedicated the past 6 or so months and have another 6 or so to go, what gives you the right to benefit off of their generosity? Plus im pretty sure that advertising a service without vendor status goes against forum rules.

I don't know if it gained any power, but I would no longer get knock events that I might a year before. Now, this could be due to several things, but I found it interesting.
Like Opinions, Tuning a car is like a butthole, everyone has one and most stink..

You know i was thinking the same thing except the pumps around here say "may contain ethanol" so i don't know if it actually does.

The car pulls like a 100 times better even than the first 280 map i posted. It's my opinion that the reason that i'm runninng so much timing without knock up top is all because of my FMIC, i'm showing only 3-5 degrees over ambiant thats 21 psi @ 8000 rpm.
When ever i tune i have always added fuel at peak torque (peak cylinder pressure) and with 8 degrees across the board fromm 3k-5500 rpm i'm making insane torque. After that i just gradualy lean it out keeping a close eye on EGT's.
FYI the reason that after 7k i faten it up is actually because i'm compensating for my injectors being At 115% duty cycle (they are just open they dont pulse much)

hey, it seems to be working well for you. PM me your mods if you don' feel like posting them here. I'm curious to see your combo. Do you have any dyno plots with A/F charts? or even better 1/4mile times, what kind of MPH are you trapping.

hks rs intake, ams upper and lower ic pipe, buschur race fmic, hand ported throttle body, comp 280+ cams, ported 10.5 hotside, buschur tbe w/ old style muffler & random technologies 3" spiral wound hfc, forge mbc 23psi spike 21 psi to redline,
I have a crap load of AF datalogs
i'll be on the dyno wed or thursday of this week, no 1/4 times but in the i ran a best 7.0 @ 98 in the 1/8 friday night.

all depends i would only raise it 2-3 degrees max, the biggest gain is going to be raise in boost.
C16 has a lower specific gravity than pump gas so it will naturally be leaner.
