Hi guys,

I need your help, my launch map was missing in my new tune, so I copied that part from my last tune, but I think something is missing.

With this maps the car makes 10psi with the 2 step, but when I launch, its bouncing all the time , I try to fix it rising the stationery rpm, but I cant fix it.

I really appreciate your help with this issue, thanks!

Here are the maps, and the video of the launch:

Do you have a top an bottom clutch switch? Why is the stationary limit at 7000?

Because I try to fix rising it, at 6000 is worst the launch, thanks!

Looks like you're just dropping the clutch too fast...

No really, I try a lot of times with the same result, also I had my car 7 years ago , but with this new setup I cant make a good launch

Looks like less of a ecu launch problem, and more of a driver launch problem. Looks as though you are just dumping the clutch. That bounce you are getting is because of the shock you're putting on the drivetrain, as well as a less than optimal suspension setup.

Can you stay on launch control a little bit longer? Also you need to log and see whats going on. Check to see if you logged any old launches to compare.

That's definitely a driver error.... Record with a go pro or something we can assist based one that video and logs of course would help. 7K and you can't launch "jumping" sounds like a for sure driver error.

Sounds like you need to ride the clutch slightly more when launching to load the suspension/drivetrain up. You will know when you do a good launch, the car will sit and go. You shouldn't need to adjust your 2 step.

Toekneee!

Try smoothing out the launch map as well...Once you pass the threshold from launch map to main map, it's going from -20 timing to whatever your main timing is as well as fuel.
