Question Need help with me S-AFC settings???

I need to know the recommended settings for a MY99 with Minnam Intake, Zex Nitrous, N1 muffler with 2 1/4 piping, Zex spark plugs, and a Unothrodox Racing Pulley....

I also need to know the recommend settings for a MY99 without the aftermarket intake and nitrous...

Do a search for how to tune with the S-AFC and make your own settings. This will be the only accurate way of properly fueling your engine.

Yep, there's no AFC settings that apply to all cars. You need to tune it yourself, especially since you have NOS.

Not for nothing, but EVERY time, since the S-AFC came to this forum, that the subject of tuning comes up - a search is advised, but I've seen most if not all of the previous AFC posts, and the info isn't there. I have mine tuned for a progressive richening from 4000rpm - >, peaking at +10-15%, depending on the grade of fuel I'm using. I don't think anyone has any dyno pulls with the AFC - at least not that they're talking about. The problem was/is that Shiv Pathak talked about the AFC when SCC's Impreza was N/A, and the lean-run caused by a tube intake was what needed correction. There was no tuning done with a stock intake, stock plumbing/Cone filter, etc. Then TECII came along, and the AFC/ITC fell into poor favor - unless you already sank $700 into them,and were kinda stuck...Guess where I am? I am getting pretty good results with a K&N cone filter running into the stock plumbing, and a 60mm cat-back, among other things. But exactly how well, and how far I am from the ideal is a whole other thing. If you learn anything new, share the wealth.
