Launch Control/Anti-lag help

[TwIzTeD_3kGt]

I'm unable to figure out why the launch control/anti-lag causes my engine to flood. The only thing I haven't attempted is to further retard the timing. Is it safe to try to do?

The original settings work OK, builds 8psi on average for me. Being on L-wheel 19T's I need the rev limiter to be higher to be where the turbos can actually spool up. I played around with it for a while but everything I touched seemed to make things worse. It always floods the cylinders. Setting the anti-lag AFR 12.0 from 9.0 didn't even change that. Any help here?

how long are your trying to build boost for?

its only supposed to be for a second or 2 then u go

A second or 2 gives me the 8psi at 4k, but it's not enough. I just want to up the RPM limit to 5k and see how that works, but just changing the rev limit and anti-lag start values doesn't work. It builds more boost but also floods worse, to the point I can't take off. At one point I had it build 20psi with 2 bounces off the limiter, but it was totally flooded after that.

I just don't get the flooding part of it. I get that the spark is happening when the exhaust valve is open so the combustion blasts out the manifold into the turbo, but why does it flood? Is it because the fuel injector is firing at it's normal time and the spark is way late leaving all kinds of unburnt fuel in the cylinder? Would leaning the anti-lag AFR way out be a solution for that?

Also, what happens when you place the rev limit and and anti-lag start RPM's closer together? Or further apart?

Set afr at 11.0, timing at -10. Should be 12 - 14 psi. I have my rpm set at 5000 but you can set it at whatever you like.

The engine is flooding because a target afr of 9.0 (if I remember right that's what it is set at when you get chrome) is fine on 360cc injectors but when you get bigger injectors it is too much fuel.

Which timing value are you referring to?

I'll give it a shot but I had the afr at 12.0 at one point and it still flooded.

Then you have something else wrong.

I don't have a computer in front of me to reference the timing stuff so I can't remember what I set them each to. I think start was -5 going to -10

sorry to bring this back from the dead, but I'm having the same issue. Did you ever figure out your problem?
