Ok so here is a little back ground on my setup so that anyone that can help me locate the correct input to use has an idea of why I am going this route.

my car is an 02, v2 ems, gt42r, built th350 with trans brake, built race motor, ect

my dilemma is this, I want to use anti lag alt funtion but I no longer have a speed sensor which is what most people have it activate and deactivate off of. My idea is to have it activate when the brake pedal is down and the brake switch is sending power to activate and deactivate the anti lag/2 step. If i remember right it is pin a32 on the harness but in the switch list on the tune it doesn't specify which option is which pin on the ecu.

How do I find out which switch option is which, and how do I locate the brake switch option for the anti lag? I think it would work well since I use the foot brake to stage the car anyway since its auto now and I don't have to wire up anything else, I just use the stock switch and signal that is already there.

any help is appreciated thanks is advance

 

you can use any LS/hs input to activate the anti lag...

Dont you have a transbrake? Anti Lag kills torque and will make it hard to bring the car up on the stall.. There is a fine line between pulling enough timing to spool the turbo and keeping the car up on the stall. You may find out that you need a much higher stall than you would expect.

 

yes I have a trans brake, but it doesn't stall high enough on just the brake. There is only a little more adjustment left in the converter and I dont think its going to be enough to get it into the power range I need to launch on. right now it builds 7lbs at 4200 rpms but I need it more in the 10lb range at 5500rpm minimum, preferable closer to 6000rpms. I am pulling the converter this weekend and sending it back to be adjusted but like I said there is only a little adjustment left before its starts counteracting the car running through. We had 2 step working before on my old v1 aem ems and it was ran off the regular foot brake which was nice and it worked but now with the aem v2 and my tuner no longer wants to tune on my car I have to figure it out by myself which makes it difficult.

and I absolutely refuse to spray the car, I don't like double power adding unless absolutely necessary and every other possible option has been tested first and failed. the first adjustment to the converter made a huge different but there isn't much left but maybe it will make a big enough difference.

anyway, still looking for which input is the foot brake switch

 

A32 is "Switch 1" in AEMTuner.

To check to make sure it's working just open up the AntiLag Tab and it will be listed under the channels.

 

Ok I'll try that thanks!
