Yeah, the only positive is it forced me to get 3.6 gears

My launches were **** and i kept bogging, but ran 14.2's @ 120's Then i blew the rear end with wheel hop in the water box.

I think what i would like to do on the K swap car is build a tubular brace out of DOM to connect the factory 6 point brace mounts into the PPF and rear end mount. That along with the solid diff mounts should help a lot with wheel hop.
I always do the burnout in 2nd gear above 7K to prevent wheel hope, sometimes 3rd gear but that's hell on the tires and harder to roll out of the box with a turbo that's too laggy. 1st gear is wheel hop city though. Basically 2nd gear and redline should keep wheel hop to almost nothing during the burnout.

I gotta try launching in 2nd, never did it with a big turbo but might work great with new SC setup. That I need to go work on...

Tried launch control at 6k with a clutch drop in second. A bit of wheel spin, then bog, then clutch smell

Vlad use launch control, launch timed from boost (both ms3 features), and your right foot and that thing will launch. Last auto-x I would clutch drop then feather the gas to keep the wheel spin from getting out of control. It worked pretty well.

Aidan, I know of those features but I am curious as to how you had your settings? Timed from launch? What were you trying to do exactly? Can you post screenshots of your launch/boost settings?

/\ Yeah I'm curious about this too. Once I get logs to Matt Cramer to figure out my VSS not playing nice with the MS I'll be setting up my LC too.

So far I tried regular spark-cut LC at 3k, it absolutely gangraped my tires in 1st gear, uncontrollable spin. I'm going to try 2nd gear launches when LC is figured out

I'd also be interested in some of the tech behind setting up a good launch control timing point. Say at 3k rpm my timing is at 10 degrees BTDC (just for argument's sake). Should I be raising my target timing (>10) or lowering it (<10)? I have heard people talk about using timing to build boost and I have seen videos of people using launch control but I don't know what direction to go in order to duplicate those efforts or even if they are safe.

For example - what is going on here? Is this safe for the turbo?


Let alone how i'd like to get my flat-shift set up properly at some point.

They retard the timing to throw a ton of gasses and unburnt or burning fuel at the turbo and spool it to kingdom come. Safe? lol I dont think so

My other concern is for my shiny/pretty FM exhaust getting nuked by something like this. I might unbolt the muffler for the next track outing.

I retard to -5 degrees. And add some fuel. It gets rid of the absurd backfiring and muffler blowing. Spools a little bit. The issue with launching with boost is that unless your on drag slicks or AWD most of the time your will just smoke the tire.

So you just add the fuel in the fuel map of where it bounces around on LC?

What happens when you're going through that area in normal driving (if it even goes through that area)?

Nope, ms3 has an add fuel option in the launch control settings. I'm using both banks 2.0ms.

You can also time boost from launch. So I have it ramp from 30 percent of max boost up to 100 percent over a couple seconds.

Yeah that stuff looks really really cool, I'm so excited to try it
So it times it regardless of gear/speed right? just a regular timer? So you basically figure out how long on average it takes you to get to whatever speed where you won't spin, and ramp it back up from there?

Pretty much. It would be more precise if I had a setup with more grip. Really right now any amount of boost blows off the tires so I have to drop the clutch and then feather the throttle to keep wheel spin from getting away from me.

Using the default timing retard after launch settings I can launch at 7psi and it is incredible. Chirps the tires all the way through first but never loses traction. It's loud as **** to pull enough timing to build that much boost though. WATATATATATATATATATATAT

I have no idea how you aren't losing traction. I almost do standing burnouts.

How many degrees of timing are you retarding after launch, and over what period of time is it being fed back in?
