Manifold glows red while running Rich??
My buddy just got his setup done it's a 93 prelude h23, td05 turbo, jonny racecar fmic, vafc hack, and msd 6 btm.
Well the first problem was too much boost. So he got a t3 wastegate from a chrysler, that was supposed to open around 4psi, and we checked that with a boost pump. But the car still made around 10 psi at higher rpms, and was hitting fuel cutout ie the ecu was seeing boost. so the only way to limit the boost to around 5-6 psi has the wastegate open at idle, so now it spools slow as hell. But we can deal with that when he gets cash for an external wastegate.
But what I don't understand is his a/f gauge is reading pretty rich (I know they're not perfect) but after about 6-7 minutes of moderately hard driving, the manifold (log style) and turbo center section is glowing red. I thought that meant you were way lean.
Any help you guys could give would be greatly appreciated.
