Antilag launch control
Hi all, I'm wondering if anyone here is using 2 step antilag/launch antilag?

I'm after a few rough ideas on Timing Retard and Fuel enrichment tables.

I'm running a GTX3076R, forged/built SR20, etc.

any help??

I tend to work with around 60 degrees ATDC timing which is a good place to start. Usually I don't add much if any fuel above the norm. Not that it matters, but this was on a GT3076R RWD SR20.

I'm only pulling about 10 degrees of timing and building boost just fine at the line on 5 degrees...

Pulling 6 out of 10 sparks iirc.

I was running 40 degrees retarded and 1.40 fuel enrichment. Made 7-8psi on the line. I may have an exterior video I could show (unfortunately, none of the boost gauge, sorry )

I only modified the settings a few times over, so not sure how even more timing retard and fuel enrichment would work however.

I'm certainly not super confident in my recommended settings. There could be much better ways to do this.

Running 5 degrees nets me about 5psi at the line

@nsusammyeb , what your fuel correction value??

cheers for the info, does anyone have a photo of their fuel/timing table?

I have mine ready to post but unsure how to attach an image.

I currently have 15% enrichment across the table,

rev cut is 5000rpm, with ignition cut 1000rpm prior, the timing starts at -2% @ 5000rpm @ 100% throttle up to -10% at 8000rpm @100% throttle.

haven't tried this setup on the car yet, but if I can upload a pic it will be easy to see if its somewhat correct.

I'm running Megasquirt. It's not set up that way. I can cut spark to richen up the mixture in the exhaust. I can cut "x" number of sparks for every ten. I set my LC to the rpm I want with a soft and hard cut and set the absolute timing.
