^^^^ do you notice if the boost wavers? mine will hit 5psi and then dump...the car shakes(the mad power under the hood kind of shaking), and the BOV is constantly dumping. never seen LC before, so I don't know what it shoudl or shoudlnot be doing. i always invisioned a constant rpm and constant boost. maybe that us antilag, ha ha

I personally have mine set at 10 kilometers an hour and I can't remember my delta but it holds me right around 4150ish.... I generally can easily build 7-10 lbs of boost no problem. Even though it it kills my clutch, I still slip it out slightly, havent really had problems. Wheeler- my boost waivers slightly but nothing outragous, and my stock BOV doesn't seem to really release as it sounds like you talking |

A BPV/BOV only should open when there is a negative pressure differential between the intake manafold and the piping that the BOV is attached to (mani pressure is less than piping pressure). This should only happen if the throttle body is closed, which if you have your foot to the floor, shouldn't happen. If your BOV is venting, this means one of two things: You have a crappy BOV that can't hold bost, or you have a vacuum leak somewhere that's causing the BOV to see a constant low pressure in the manafold. If the BOV is constantly venting a small portion of boost, it's the former. If it's building boost, then dumping, then building boost again, it's the latter. |

Also check your rev limiter settings. Mine is currently set at on over 7100 and off under 7090. You get a smoother rev limit if there is only a 10 rpm window. Also, you may have a really large value in the rev limit ignition retard. Mine is set at -9.84 degrees. When I'm using launch control, I'm varying between about 4400 and 4500 rpm and boost is holding at 9.5-10psi. My BOV only vents if I let off the gas and it vents the 10psi.

Hehe, try a 5rpm window in your rev limit with -2* retardation. That'll be uber quick.

My rev limit is raised via UTEC, anyone know if this will interfere with the patch, or will I have to offset the delta in accordance to the utec value?

Don't quote me on this, but since the UTEC is an interupt/piggyback, I would guess that the launch control will still work. If it doesn't, you'll just need to get rid of it and transfer all of your maps to opensource.

It would definitely still work, but he's asking if he should reference the delta off of the ECU's rev limit, or the UTEC's rev limit. My guess is it would be off the ECU's limit. I imagine that the way the UTEC raises the rev limit is by simply making the ECU always think it's just below the stock rev limit, and since the UTEC is controlling all functions at that point anyway, it can continue to adjust boost/fuel/timing. Which means that any code in the ECU that references the rev limit would still see the stock rev limit.

I could, but the less I have to mess with wiring the better, especially since I am flashing along w/the utec anyways.

I wish this was available for those of us running the v1 AP on 2.0L cars. I just might pick up a utec if its cheap enough just to use for launch control.

yeah but I don't know if I can move my map over to it. I haven't really done much reading into the opensource stuff.
