What the table does
While anti-lag is active, this table adds a fuel correction on top of the normal fuel calculation. Extra fuel can help create more exhaust energy, which is what keeps the turbo spooled when you're off the throttle. Not every setup needs it, but many run better with some.
How it's usually mapped
The common axis is Anti-Lag Trigger Time Remaining. The shape looks like this:
- At the right side, when anti-lag has just been triggered and has the most time left, you have the most added fuel.
- Moving left, the correction tapers down.
- At 0 seconds remaining, there's no added fuel.
That taper means the extra fuel fades out as anti-lag ends, instead of dropping suddenly and causing a lean hiccup or a sudden change in engine behavior.
Our approach
Start with small amounts and add fuel only if logs show the turbo isn't holding speed. Too much fuel builds carbon, soot and exhaust temps. Anti-lag is hard on turbos, manifolds and exhaust parts, so log EGT and lambda and keep sessions short while tuning.
Set this alongside anti-lag ignition retard and the idle valve bypass. The main anti-lag article covers the rest of the function.
