Correct, it cuts spark and retards timing.
I’m hoping to get a good enough launch to not need the launch control as it is very hard on turbos…
OK here is my analysis from the launch data from the 11.7 run
It clearly shows the rpms were rising after movement occurred (movement did occur at the rpm saki said) bhut that the bog in rpms was caused by the throttle being cut.
Do you agree with my analysis saki?
I have a theory about what caused the throttle cut, I will test it on my way home and let you know.

Gotcha… Sorry, thought you were closer to Pitt. Either way good luck with the car!

Thanks!
Lol maybe your clutch switch is sticky or misaligned and at 5000 rpm your anti lag kicked in
Well the tune actually had both the antilag style launch control, plus the “throttle cut no boost building” style in there as well…
Now the antilag system was set lower than the throttle system, so it should never have activated.
But I removed the throttle based system from the tune, I will test it that way tonight and see if I can replicate the problem.
My 3rd (and last) run of the day I did launch at 5000rpm.
The problem with it was that I spun all through 1st gear due to no traction at the track that day… then bogged going into 2nd because the speed wasn’t there.

It’s setup exactly for that. I’m just not using it at the track until I hone the rest of my technique and find the limits with just boost 
BT, really I’d say spend the time trying to get all the tricks dialed in, there’s a lot going on and it all happens fast n furious with little or no time to react once the motor on the boil. At the very least the 2-step/antilag launch is a measure of consistency. IIRC it is ignition cut, no? Not full fuel flow, so is it really hard on the turbo (are you firing flames lol)
Looks like it spools really slow at first then between 5000 and 6000 the IM pressure basically doubles, must be fucking violent, based on the last log you sent. but still you are losing spool between shifts. Wasn’t, for some people, the antilag/flat shift also tripping the knock sensor between shifts and retarding heavily?
Can you post the log for the run, with ignition? I’m just curious.
Or just launch like that video, maybe that’s the method. Don’t forget to turn off ESP lol.
Actually I don’t have any good logs from the track as the laptop kept stopping logging at the top of 1st gear lol.
Need to check it’s anti vibration settings.
I can post some street log data though.
Please stop saying “Lol”.
Grown men don’t go around saying lol all damn day.
If your goal is to break records with your car, please do it and stop trying to get into the book of world records for saying lol in every damn post you make.
Thank you and please continue your forward advancements with your car.
You need a lesson in launching the b5. Immediately. You’re launching at far too low rpm with no spool. So it’s like you’re launching a 3600 lb Awd car with 180 hp and similar torque. Not going to do anything but bog. Needs more rpm and revs momentum.
Go watch this.
LOL!
LOL WTF FAW, smh
Damn you pt beat me to it
FAW is on to something though. I’ve noticed that over the past year. Virtually every single post BT has ever made has lol in it.
Man I want to lol at that… haha
it’s true…either a lol or the happy face drawn with characters. I noticed it on your build thread on AZ back when I started this thread.
p.s. my OP from this thread…jury is still out! 7 months later and you’re the 18th fastest B5 on our list.

Can you fill that in for me? Adding you to the list.
Lol is what I always say instead of “fuck you”. Read my replies to a lot of your posts and you’ll see a fair amount of “lol saki”.
Maybe you hear people let a little laugh as a first response when you’re talking to them too…same thing. Lol.
DIAF is literally all I have to say to you on this site jspunk.
