How do you go about hooking up the clutch switch to the anti lag system?

You are going for 2-step by those settings it looks like?

Yeah pretty much...just for launching when I'm drag racing....I'm building boost just fine when I'm sitting still, the car just falls on its face when I let out on the clutch, unless I ride the clutch out a good ways...

Fuel cut should be at your normal rpm limit(7~8k?).
Ign Cut and Rev retard should be the same. Try to lower it to the point where you are max boost building.
Max VSS: 2

Ok I'll give that a try and see where it gets me....thanks for the suggestions...

Hey Briou, If you email me a data log of launching (with "tuning" tab opened) and the map used for the log i'll do your first revision is free

Little testing on my s13Rally style anti lag tuning and system set up explained.
This car is using the secondary air injection kit I found this particular set up doesn't need much keep the turbo boost happy. On ignition cut set up at the track or under heavier use you do start to get a good bit more noise and flame. I like the ignition cut option as it helps keep heat/stress off the exhaust valves.

Throttle bypass ALS on the Galant, tuning it down a bit for the snow/ice.

Seems like you're running pretty small turbos tunermt. Ever set this up on a car with something like a gtx3576 or Borg S300 series?

yep have also ran similar als on s400 and large frame garretts. (of course those are normally on drag cars or large displacement engines.

some launch control with "drag style AL" and the same car with no lift to shift set up (actually works VERY similar to a throttle bypass style ALS).

This stuff's neat, but it's also neat to clutch kick a laggy car a bunch. That driving style can be very exciting.

I am planning the following system.

- Evo SAS valve.
- Vacuum canister / check valve
- PWM solenoid on VAV canister to SAS valve.

I have a couple questions. I assume the injection ports must be at a 90* angle to the manifold runners (to induce suction from charge pipe). Will the exhaust overpower the charge pipe or will the SAS valve act as a check valve? Also, can I utilize cyclic timing cut and add fuel or must I retard timing to ensure fuel gets to manifold?

you might get something like that to work but it seems you have some confusion on how air makes it way into the exhaust. (pre turbo exhaust is under pressure, the exhaust manifold will never "suck" any air in it will try to do the opposite.)

I was under the assumption that this was how the Mitsubishi system works? Charge pipe to SAS valve (actuated by ECU) and SAS valve to pre-turbo exhaust manifold?

Can you give me an explanation of how it is supposed to work?
