I have a big problem to do a good launch with my new setup, I have some lag but just in the launch, after the launch the car is awesome, no lag between gears.

I opened the Thread to help me set a good launch, I see that there is another similar topic on the launch control and antilag but only see maps with stock turbos evos.

I would like to see the launch and main maps in large turbo setups, I hope that the guys that have larger turbos projects here in the forum do not be selfish with their success they have had on this topic and that they can share it with us.

In advance thanks very much

 

Launch from a higher RPM

 

My launch is set up to 6500rpm and sucks, my car does not go well.

 

Are you slipping the clutch enough?

 

Yeap, I have tried almost everything I need is a good launch maps to make boost at the launch.

 

How much boost are you building on the 2step

 

6psi max maybe less

 

I was not entirely happy with the stock ecu launch control setup. I was never able to build enough boost to get a great launch. For what it's worth, on a 35r type setup, i was launching at 7300rpm.

Here my maps, maybe I have something wrong:

 

Jon, you should be able to go to -10 or even -15 degrees on your 2-step, that may help spool a bit more. Maybe try adding a bit more fuel as well?

 

Also keep in mind when you transition maps during launch you have to smooth that transition. Especially if your going from -10 to -15 deg block right into your positive timing on your regular ign map.

 

I don't understand how to do a good transition, I heard about this and want to learn how to do well.

Can you explain me better how to do a good transition???

 

Just make things smoother. Use alt+G in ecuflash to open the graph, that will help.

For example, instead of going from 30 to 15 between 4750 and 5000 rpm, start decreasing at 4000 instead and make it more gradual. Like 30, 25, 20, 15.

 

Thanks dude!!! understood

I'll try increasing the rpm cut to 7k and make another maps.

 

How looks this new maps??? I made a good transition??? to see if I get it.
