Cobb AP has the rev limiter already on it where it builds boost. Put in 1st gear , push clutch in and floor it. i tested it for a couple seconds and it builds boost. So this is for people with out the Cobb AP?

Yeah but how much boost? Couple of lbs? Typically LC don't build much boost like this will.

I guess ill try it. I am on SD with a Gm IAT welded to the Sti tmic. I unplugged it completely and the IAT temp read -0 so I think I need to just "interrupt" one of the wires rather than completly disconnect the sensor all together. Next I will change the values (-40 -20 or what ever the default value is once the signal is interrupted) to ~-27 as a starting point. And see if that works.

It made about 8-9 lbs in just a few seconds.

Yes with just launch control you will build boost, but with this type of setup you will build much more and do it faster...
so no "/thread"

Ok so I finnished up the wiring today, I interrupted one of the signal wires from the IAT to a "normally closed" momentary push button. Set the IAT comps to -32 disabled the p0111-p0113 codes. Set the 2 step to 4300 cut and 4290 resume. Fired it up. Ran normal. Hit the 2 step it built a little bit of boost and pressed the button the timing dropped to -10 lots of pops etc and it built about 13-15psi (too many things to watch like dam and fbkc!) it seemed pretty slow to rise. My IAT fuel comps in that range are +30% it's super rich. I'd like to compair settings to what you guys are running
Ps the roll on anti lag is pretty sweet

how much boost do you really need to launch? 9 -10 psi is plenty to get it off the hole any more and you will prob just spin.

What makes one "better"?

Must have a ton of power or really bad tires if you can spin them. :P

This wasn't intended to replace launch control, it was intended to aid launch control.

My VF43 will make 10psi on LC. But a larger rotated turbo won't spool up as easily. I personally have found my LC to produce a slower 60' time than launching without it. I did the "hack" but have not played with it all that much. It works great so far for roll races, but off the line it is worse than useless on my car.

Also, if you think spending 350-600 for an AP is justified just to have launch control... Then you should be nominated for noob of the month. Most open source roms can be patched or modded to have lc/ffs. I know mine does.


Merp SD w/NFSW LC/FFS.

This isn't my first Rodeo. . My last car i had a gt35r that spooled up 15 psi with launch control.. And I never said buying the ap would be just for launch control. I'm just saying this mod is useless and your a dumb ass for doing this for a roll race any way. .. That's even more retarded , have u not heard of Brake boosting? And using a hacked up way to build boost is so not safe for your engine, in for next thread " oh **** I just blew my motor ".

My open source Rom also sets basic launch control by setting rpm and you're done.

What did you have that spooled a gt35r off regular launch control to 15psi? Unless you were redlining at that 15psi spool :P

You like brake boosting? I absolutely hate it!
By your earlier logic, better = easier.
Therefore, it's easier to press a button to get full spool faster than brake boosting. So would that not mean that rolling anti-lag is better? :P

I don't even understand what your first statement and question is. Better = I didn't hack up my car for nothing. Are you not coordinated enough to press the brake and gas at the same time??. Being to lazy to brake boost your causing a lot of stress on your motor building boost in that manner and will most likely have engine problems/failure from it.

my last car was a rsx drag car and was the fastest rsx in the state.

Any how I'm done with this thread.. I'll be waiting for the Oh **** I blew my motor thread..

Hacking up the car?! Where's that coming from?

Are you the one that blew your motor on valentines day? *Or was that the other fastest rsx in nevada? *Seems you got all motor blowing knowledge.
I'll be waiting for ANOTHER blown motor from you.

You might as well leave. You aren't helping a single person in this thread.

My last car was a Trans Am and the fastest Trans Am on my block.
My current car is a Wrx and the fastest WRX on my street.
My future car is unknown but will undoubtedly be the fastest car in my garage.

Yea I blew my motor on valentines day. It was my stock motor that I drove for 3 years making 440hp . Then I installed my built motor.

Don't hate cuz your to stupid to realize this mod is useless... My contribution to this thread is to make people think about doing this before they go and potentially blow their motor..

If people want to roll race without worrying about engine failure just brake boost . And for those who don't know brake boost = put in gear you want to start race in ex. 4th gear step on gas , car will build boost mean while hit brake just enough to keep mph at desired start mph and hold. . Honk three times and at third honk floor it and release brake.

So you admit that your judgement is thoroughly flawed. Great.

Now you also don't tune your own cars. So you don't know how this mod even works.

Your fallback rant is about brake boosting. But this was conceptualized for launch control. Can't brake boost from a stop or have you got a magic car? I'd say no since your last magic car blew up.

Just let it go about this mod. It can be proven very useful and very effective. User error will blow motors, NOT this "hack." Just like your turbo kit didn't blow your motor. You did.

Serious question:
Did you really part that thing out? Or did you put it back to stock to sell? Or what happened to it?

I didn't blow the motor , the stock motor wasn't built to handle the amount of power I was putting down. That's all.

I had launch control setup on last car with tuning software. The right way of doing things.

I sold the shell to guy in Washington , built block to guy in AZ I think and misc stuff to others. . So yes I parted it out and regret it now. .
