dsmlink launch control on automatic

[britdog]

So i was wondering how the 2 step launch control is activated on an automatic car.WTF How do you engage it? and then set it to launch when you want it to? i know my buddeis is with the clutch but mine is automatic. thanks

I have a different ecu and manual 450cc injectors.

You need everything I listed in the last post for the tune to be correct. Manual ecu, manual fpr, 450's...

Keep the stock fpr and the injectors will flow 450cc's..But on 1g manuals even tho the injectors flow 450cc's the fuel pressure is lower..So they really only flow about 410cc's..

But you will run rich if you keep the stock auto fpr..Which is why the manual one is needed..

stock stall auto awd i can launch at 12 psi on a evo 3 16g *real* and roast all four on dry pavement.

if your gonna be racing your awd auto i suggest shift kit. full line pressure mod. racing atf "*no friction modifier* and a line lock placed on front and rear brakes.

With a 16g I can brake boost to about 2800-3000 with a stock tc and get 6-8 psi.(does take alil bit to build, its not the instant I get on gas by any means) 10-11 if its real cold out and then I spin all 4 everytime.

Most ive seen was just over 13 off the line and I never pulled through brakes.

I put it in neutral when going to launch and bring rpms to about 2000 and pump brake a couple times and stand on brake and drop rpm, put in gear and brake boost as long as I want (within reason, Ive seen reports that the fluid leaving the tc when your brake stalling it can increase as quickly as 80-100 degrees per second...note thats fluid leaving tc not all the fluid in your trans! not saying your overall trans temp would raise that quickly so be careful!)

No 2 step necessary for an auto. You launch with brakes and gas pedal. It's called brake boosting

Have you ever tried to hold back an auto at 20+ psi with the brakes and no 2-step? It's basically impossible, and it's very hard to back off the throttle the right amount.




If you can't get enough boost by brake boosting, enabling a 2-step will do you no good. If you can't get the RPMs up, why would you need to limit the RPMs? You must have some type of issue if you can't get a 16G to brake boost. Tuned too rich or wrong timing, bad compression, exhaust leak or wastegate issue, intake air temp too high, or you're just simply not waiting long enough.

If you're launching at 20psi, you better have upgraded brakes already.
