dont hit the limiter?
Re: how can i stop the car from twitching when i hit redline
Don't red line it.

Reprogram the ECU to give you another 1000 rpm before the rev limiter.

this is actually something you could do yourself I suspect, I've only used the G4 software a couple of times and I could figure out how to do that
Re: how can i stop the car from twitching when i hit redline
Its not easy all the time to perfectly shift without hitting the limiter... whats this g4 software? How do you mapp it out? And rising the limiter i would love to do but would there be any problems after :$ car forged etc etc...

Do you have a dyno chart? You might not even need to go all the way round to the limiter (or just before) to get the most out of it.

Re: how can i stop the car from twitching when i hit redline
Looking at that graph, you don't need to rev it all the way to the red line - changing at around 7k should result in max acceleration as your power starts to drop off a little there, and you'll still be dropping it in that nice flat bit of the torque curve.

yeah defo try changing before 7krpm, no need to rev further than that since you're not making any more power up there.

it's the software used for mapping the link g4 ecu. you;d need to find out what software your ecu uses depending on what ecu you have
as already pointed out you could shift gear earlier though.

Of course it does!! You're going from 450bhp to zero in a split second, so I'd expect the LSD to lock up and the car to squirm
As others have said, either learn to drive better or increase your rev limit
Re: how can i stop the car from twitching when i hit redline
Thanks for the help guys... i gonna think about it.
Changing early is easy said then done when it hits full boost from 4000rpm you 0.10s of a seconds to change in 1st and 2nd gear im not that fast on changing gears if you guys know a special way let me know... lol
Right now im just comfortable in the spooling of the turbo power band otherwise things get a bit twitchy

Change back to standard LSD, i see no reason for a 2 way on a road car

I was thinking this would fix the issue... 1.5way lsd which is standard. I think this lsd can be adjusted to 1.5 way
