I've been reading every thread I can, this site is a great resource.

I've never played with commodores before but have plenty of tuning/car experience so should pick it up pretty quick.

The car will be used for more than just burnouts although that's cheap fun for the kids. I'd say soon it will be at the drags and then we may need to look at making it quicker

a big big help for burnouts will also be to richen up the bottom end of WOT... (holden leaves it lean as under 3000rpm). makes it way easier to start spinning the wheels if you actually have power off the line.

for burnouts, I would suggest leaving the thermostat a bit more open than you need, then adjusting the fan ON temp in the memcal to 90 deg. that way on a static burnout the temp will still be regulated to 90 deg by the fan.
by default holden turn on the cooling fan at 103 degc and the high speed at 108 degc. that may have helped it overheat during your first burnouts...

also another thing to keep in mind with burnouts, bouncing off the limit cuts fuel and will help to make a motor run lean and over heat!

also bad for the valve train not to mention the bottom end.

I see there are 2 limits to set.

Does the lower limit initiate timing retard by any chance before a fuel cut? If so lowering that maybe be any effective way of not hitting the fuel cut so easy.

in the standard tune the lower number is when it re-applys fuelling.....

so 5500 and 5400 would mean at 5500rpm it will cut out, and once the rpm gets down to 5400 it would cut back in.

timing retard close to redline was added to 12p if you wanted it.

Except hes using a vs pcm which adds a whole lot of work to converting to 808 to use 12p lol

Oh yeah, when I think 'lexen' i always picture a VP

you mean VQ statesman? The one I think you are referring to used the VQ front end with toyota front bar?
