Here's a launch map I've been trying out. It's nothing too extreme since I'm on the stuck clutch anyway so it's useless for me to be launching with boatloads of boost. I've never actually launched the car with these settings, I just got on the 2-step a bit to see how it would work out.

Logs (ignore rpm, I had accidently changed the adresses in the MUT table. my 2-step is at 5k)

 

Thats nice, i might try your settings i cant get the car to knock less then 7, but im building like 18psi on the 2 step which i think is a little much,

Im also at -10 timing on 2 step which also could be a tad to much haha

 

Yea, like I said I'm not going too aggressive because I can't really take advantage of the extra power off the line, I'd just melt the clutch even faster

 

lol sweet ill try it out when i can and post back with results

 

widge... in the negative is partially your issue, you may also need to set your TPS to 60 or 70%

 

raptord... the issue isn't building the boost without knock, that part is easy .... its the actual launch process that is the issue because when you give the appropriate fueling for everything to yield no knock and the correct boost level, the car bogs off the line and sounds flooded really.

 

Ease into the launch map.. Mines is set to active @40% Tps.. So what I do is ease in at 40%Tps then mash the pedal.. See if that helps,,

 

This is my launch map.

It builds 10 psi at 5250rpm and doesn't knock or bog. The rest of the map is my normal map. I've found this integrates the best and produces good runs for me.

 

Some good info here

ive got my TPS 40%, ill try some of the above mentioned settings and see how i go

Cheers guys

 

Can you place another picture with your actual timing map

 

+1 and can you give us a few details on your setup? Have you tried this map at a 6k launch?

 

So here is my ignition map

I let out the clutch pedal until the car starts to move, then I push the pedal back in a bit, while I pretty much almost floor the gas.

I have my launch map tps value set at 50% +. Once I lay into the throttle more, you can hear the car start to pop and boost builds. The way it's set up right now I get about 10 psi out of the hole, and it's enough to spin the tires (stock size). If I launch any higher, it will just spin more. I don't bog at this rpm, and I can cut pretty consistent 1.6-1.7 60 foots with my street tires.

You can lower the timing at your launch rpm to increase how much boost you want. You want to keep it pretty rich, but not to the point where you are flooding the engine. around 10.0 works for me.

 

Something else to try here i guess...

Thanks for the input.
