2 Step systm not wired correctly?

[birel21y]

Hey guys,

I have a crane cams ignition with the 2 step feature. Ive always thought when the 2 step is activated that it would be killing spark, therefore running full rich on my a/f gauge. But when i activate mine, it goes full lean which tells me its killing fuel. I have it wired into the light brown wire comming out of the silver 3"x4" box that mounts on the passenger side inner fender by my CAI.

hey man, sorry I don't know the answer but definitely get that figured out. i dont think leaning out the engine is the primary intention on a 2 step lol.

anyways, bump for some help.

Paul knows those engines pretty well shoot him a PM and see what he has to say.

I never paid attention to my A/F ratio while on the two step but the reason it could be reading lean is b/c its pumping not only raw fuel into the exhaust BUT LOTS of unburnt oxygen or air as well. There is no way a crane ignition is going to cut fuel. Its tapped into the ignition system only. You're fine I'm sure
