Vg30e Launch Control

Post by tht_z31 »

What’s up everyone, I’ve been playing around with the launch control and got a couple question to get some more boost. I had limit at 3500, retard at 3300, and retard at 0, this got me 1psi.The cycle on the limiter is very slow, about a 1000rpm drop between each cycle. I raised the limit to 4000 and retard to 3800 and still super slow. Kinda sounds like fuel cut with no ignition retard, are the vg30e ecu capable of ignition retard for launch control? Is there any way to speed up the limiter?
Thank you in advance

You can try adjusting the rev limit count. What the LC does is effectively temporarily set the soft limiter to this RPM when it is 'engaged' and same with the ignition timing

When testing on my cars, I think I had it lower, to try and get the PSI up faster

You’re the man Matt, appreciate it
I can’t seem to find the rev limit count.

Unfortunately there is a reason for that. In the RB30 which is very similar, it is adjustable. However Nissan hard coded it to 200 for Z31 as you can see. So we can't adjust it
