Quick ? S-afc Before Dyno

[rowland2004]

K well i know no car is the same iam just asking as ref.
But i have a 92 GSX
Big 16g
550c
FMIC
Apexi S-AFC
W. 255 pump

Iam getting the car on a dyno next week i hope if they have a opening, but the guy that had the car before me had it dynod to 300whp @ 22psi

But it would only run good WOT nothing good in between.

Here where the settings for the AFC when he had it tuned
LO THR. HI THR.
1,000 -3 1,000 -3
2,000 -5 2,000 -4
3,000 -5 3,000 -5
4,000 -5 4,000 -15
4,500 -5 4,500 -21
5,000 -5 5,000 -21
6,000 -7 6,000 -30
7,000 -8 7,000 -30

But like i said i know no 2 cars are the same but when tuned should the Fuel get Leaner as u go up in RPMs.

cause since ive richened them up a little it runs soooo much smoother.
Thanks

With 550's you really shouldn't have to be much farther then -20ish, looks to me like the settings you posted are for a car with a nice boost leak.

To get your low's properly set you need to watch your Fuel Trims on a Logger.

A wideband would help out a great deal it you don't you one.

Yea i have a LC-1 Wideband also,

But all iam wanting to do is just set it close to normal for now to drive untill the dyno.

So wasnt sure what a good setting across the board would be.

Thanks

Just watch the Wideband and shot for 11:1.

sorry pretty new to this, all that i see the wideband reads is 11.2-16's when iam a little pass 50% Throttle. IS that right or what should i be reading/and how much Throttle should i be giving it to check the readings thanks.
