s-afc setting

[1FASTRICE]

ok heres the deal, i had tuned my s-afc to my 98 gs-t and the car ran a lil on the rich side but it ran great.. i just finished a motor swap (94 laser rs)..mine blew... anyways, now i have the 1g intake manifold 2g exhaust manifold, same 550 injectors, same 18g turbo, same greddy fmic all my bolt-on's are the same except the intake manifold... now the car is running extremely rich (floods out the plugs once in a while) and the a/f gauge is pegged at the last rich light... any ideas where to set the percentages at.. maybe just to get an idea where to tune?

You sure you don't have any boost leaks?

What are your settings like?

not sure how to tell if i have boost leaks, but say i dont.... my settings are according to the road race engineering website for a setup closest to my mods

You shouldnt go by those settings, every car is differant! you need a logger and you need to set the lo thro, and hi thro to 0 across and log it then you can tune it, dont go by those. Also if you want to do a leak test, heres a link to the how 2

Agreed, make sure you have no boost leaks, and your timing is dead on. Then get the logger out and start tuning with that. Guessing just doesn't cut it.

Also would like to add that the tech article for tuning helped when I tuned my gsx. I always start at 0 and then tune according to the car as needed.
