Ok so in my previous post I spoke about the button problems, now I can get the lauch control to work with the laptop plugged in and can set all the settings ok, but what seem to be failing at is building boost...... so without setting the rev limiter at something silly, 5k plus I am only able to get about 3 ish pound of boost?

these are my current settings

R33 Rb25det = 249awkw @ 15psi

LC Rev limit cut = 4500
LC rev limit retard = 4500
LC Ign retard = 20

I have played with different combinations but can't get any more boost?

Hope someone can help

The ECU doesn't do negative retard, so set it low (say around 0 BDTC)

With RPM limit cut, start low and work your way up until you start getting some boost. Retard only set slightly before the cut as you won't need it after that point.

You can only build so much boost up depending on size of the turbo, how quickly it spools up and boost control

Thanks Matt, will give that a try tomorrow

Matt you Legend......... been playing with the settings and now can build about 8psi on launch and wow so good, just working out the correct speed to cut it back off again

Cheers, James

Good stuff!
