how can i create more boost at the two step...currently at 6k i only get about 6 psi. ive read some ppl get as high as 15

 

raise the stationary rev limit, or decrease timing in the two step load areas.

 

log while using the limiter. Pull some timing in that load/RPM area. Usually 120% to 180%.

 

TB - you're seriously the only person i've seen do this.

 

Lol ... maybe. I'm a trailblazer man ...

How do others do it? Or do you mean that I'm the only one that raises the boost? I honestly haven't had much luck with more boost ... I've been bumping mine down ...

 

Hmmm prolly just raise the rev limit in the 2 step.. what do u want to launch at full boost! bye bye t-case!

 

its usually the crazy ones who blaze trails!

but yeah - you're the only one i know of that actually goes through the trouble of using timing to raise boost on the 2 step.

I never bothered because the track prep is so bad I have a hard enough time finding traction.

edit: my 2 step is set around 5600 and i get around 7psi.

boost on.

 

ive gotten like 10 on mine... dunno how jus flashed it and poof... but then again i did have some one provide me a tune :

 

Same here ... I'll dial it in based on prep. For instance, at Steele I'll spin through second some times if there are no big HP cars there. But, in Montgomery they actually prep for T&T and I dial it up to get a little spin.

Right now I'm at around 10 psi. I went to 13 at Montgomery the last time I was there but my clutch couldn't take it. Time for something grippy ...

 

im pretty sure my clutch can hold it. I have a twin carbon. But my question is if i lean out the load cells in the two step would..WOT pulls in every other gear be effected

 

I've been doing the same thing as TouringBubble for a long time too, and the DSMLink folks have done this for even longer; it's a fairly standard "software antilag" trick. The load and RPM combination you're likely to hit while sitting on the stationary rev limiter isn't really something you're going to touch normally; the load is generally too low and the RPM generally too high.

Just pick the RPM you want to launch at, log the car while sitting on the stationary rev limiter, and lower timing in those cells a few degrees. Hilarity ensues.

 

yeah - i knew the theory behind it, but didn't realize it was a common practice. TB is the only one i've seen post his timing maps with the funny two step block of timing. And it is convenient that you would rarely hit those cells during normal driving.



now is their an advantage to using a lower rpm 2 step, with more boost, as opposed to a higher rpm two step?

ideally it should give you a little more of 1st gear to wind out - but in practice does it really make a difference?

 

I'm leaving at ~ 15psi with the HTA 35R...haven't tried for more yet.

 

Good question IMO. It seems logical that if you can get the car moving by slipping the clutch with the same results, it'd be better to have more top end power available. Not sure though. Its all about the big ol' bog factor.

 

is there any chance someone can post a standard map and map with "launch settings" ?
