Has anyone been using launch control and anti lag for racing.

i would love to know if anti lag is any good for 1/4 mile racing as i need something to keep my boost up between gears.

any recomedations or where to get it would be excellnt.

Antilag is good for keeping boost up when you are off the throttle, but it does put tremendous amounts of stress on things such as exhaust, exhaust manifold, turbo, exhaust valves etc. Id tell you to talk to MRT as from memory they do Link ecu's which can do anti-lag.

i have a power fc but i dont think its the pro series. i might give mrt a call, but i dont need it only for the street runs. never use it any other time, that way i hope it wont put to much stress on my turbo and so forth.

yeah but you dont have to use anti lag all the time, plus some people have the cats hollow so more air can pass through, i just want to see if anyone has anti lag on there gtr casue i found out today that you need to have a motec computer or power fc pro to run it, i have an older power fc so im looking for something after marker to run.

u can't drive around the street with anti-lag, for the simple fact that anti lag is a function where car have to be driven with at or near WOT 100% of the time otherwise she'll bunny hops everywhere and it get worst if u back of abit and it kick on like a pendulum effect. So it's WOT or nothing for anti-lag and another thing is u need deep pockets, mine aren't deep enough, as turbos are replace every couple thousand of kays if ur lucky.

i already know all of what you wrote, but its only so i can get the time that i want, after that i wont use it, casue its to much of a hassle blowing things up and fixing them.

but thanks anyways.

I don't think antilag will be a major benefit to you on the strip. If you were doing rallying or circuit work it'd be more of a benefit to you.

But launch control will help get those 60' times down and more consistant.

The two cars I've been in with launch control, and both launched amazingly.

The GT4 (4wd) launched better than anything I've ever been in. So hard that you found it difficult to breath while launching and acclerating in first gear !! Mind you, it does have around 550hp :(

The other was a R33 GTS-t (PFC Pro), and it launched very well for a rwd car, far better than I could in my R33 GTS-t.

With both cars when launching with the launch control, when the launch control was activated and revs built up, so did boost (while you were stopped still).

It's weird seeing the boost gauge go up when your stationary...

antilag wont kill turbo's as quickyl as you think. i know of a subie thats been running the same vf22 for over two years and its only getting tired now, thats two years of mc type events.

you can wind the antilag back so its not so agressive (and so you still have brakes at low speeds)

link do it for line's i thought wolf did it as well?

The power fc doesnt support anti-lag, simple. You need a management system that can "cycle" the engine and purposely make it "miss" on certain cycles to get fuel into the exhaust manifold and then ignite in the exhaust manifold (while also keeping the throttle plate open a small amount to keep letting air into the engine).

The only way I could see of doing it with the power fc is by the old and crude "bang bang" method, which is injecting fuel and air straight into a burning hot exhaust.

If you want anti lag sell the power fc and buy a new computer-

Your options are:

*Motec (both the M48 and M800 have anti lag and Launch control as standard)

*Autronics (also has antilag as standard

*Wolf (not sure if its standard)

*Link (definately not standard you have to buy the addition chip which is about another

500 - thats the case on the wrx ecu anyway).

*Im not sure about the Haltec and microtec.

For simple ease of Antilag being turned on/off autronics is the only way to go - it can be turned on by simply flicking a switch - where as the motec an dlink the engine needs to be switched off and started agiain to engage it. So by that I mean if you driving normally and pull up at the lights - Autronics is the only one you can simply turn on without turning the car off.

    • I got the four AN10 fitting welded up to the cam covers and started up making the head to sump breather/drain lines. The front passenger side cover I used a 45 up top and a 90 at the bottom into the stock VCT head drain spot (3/4" BPST to AN10 adapter) thats unused on the RB25DET NEO with some speedflow flame shield to protect it from the manifolds heat.   back passenger side was a 90 up top with some flame shield and 45 at the sump end. The rear drivers is 45 at both ends   the front drivers fitting is capped off for now but ready to go if i want to try moving the breathers around. I was told by the fabricator to leave all the welds raw for now to make sure there are no pin hole leaks. A lot of cleaning up, re bundling looms and degreasing to go as well as final assembly on the cam cover baffles. The first real test will be 28th March at a Circuit event. added complexity and more spots for leaks but overall looks relatively neat imo
    • Yeah i think the dash needs to come out. To get the loom or maybe just climate control and radio cluster. My mirrors are done i think the motors don’t work so well after flood haha i need the ac fan, you said you wanted to keep it for your 31 and interior loom not including boot. The wiper motor. I’m not sure how good the window surrounds are on the exterior on the pintara.  I will message you to get your bank details shortly 
    • Just another barrier put up to stop cars being modified. When we're all driving Chinese sewing machines, you won't want to modify it anyway, and you'll likely already have slashed your wrists and be locked up in a padded room for your own protection.
    • Yes, but no. I wouldn't want an IC7, because I think they are ugly, cramped and most of the displays I've seen are garish (and granted the last bit can probably be avoided). I wouldn't want to pay for the UC10. Probably wouldn't want to pay for the IC7, for that matter. And, it's an R32. I have cable drive speedo. Although, thinking about it, that's not a big obstacle, because at least I can throw the electronic sender back into the R33 box and then find a way to emulate the original (R32 or R33) speedo head's conversion of the saw-tooth AC speed signal into the square wave that the ECU wants, without the 1990s approach of hiding a gutted speedo head behind the dash. (another Arduino project, no doubt). I like the technical aspects of the big digital dashes, but I aesthetically and just general originality and feel-wise, like the original dash enough. More? Yes, more. If I had a UC10 I'd want to make the dash look as close to the original one as possible most of the time, and only flash up "DANGER TO MANIFOLD" when it needed to. But the other aspect of the 3-DIN slot digi gauge that I'm contemplating is that I'm a tinkerer and can barely resist a project, even if I don't need to add another to the list of unfinished ones. And I think there's enough precedent of others out there that have proven which equipment works (ie, is not washed out, or slow, or prone to failure, or all the other problems that can afflict such a project). I'm not quite enough of a micro-controller tech head that I know the best way to approach all of these decisions, and so striking out on my own to achieve it years ago would have led to unhappiness. But now, it seems like a project that I can actually achieve on the first or second go, with only a few sleepless nights. And that's why I'm actively thinking about it now. I would much rather have a thing in my car that I made from more-or-less scratch that does what I want, rather than something that someone else made that does some of what I want, not other stuff I want, and/or annoys me in some fashion. If I'm going to be annoyed, I need it to be my fault, so I know who to blame, and who needs to fix it. As an example of that - I have surveillance cameras at home. No, I did not go buy a kit with a DVR and 4 or 8 or 16 off-the-shelf cameras in a kit. No, I did not want to use any sort of could service to record or access the feeds and recordings from outside the house. No, I bought my chosen cameras directly (from China, lol) and built the DVR myself using a couple of different (ie, this was attempt 1 and attempt 2 to get a system I liked) software packages, running on Linux, with the server being a virtual machine running Proxmox. I found a way to offload the image recognition part of the system to a dedicated AI processing board (a Coral TPU, for anyone who cares) with the hardware passed through to the server on the VM, motion detection offloaded to the GPU, all storage is local in the home network, accessible from outside via my own self-hosted VPN). All done so that I could seal off the Chinese cameras in their own network where they can't access the internet and dial home to the CCP and backdoor my network. All things that you can't have if you do what is commercially available. And even with all the f**king around it has still cost a fraction of what it would cost to buy commercially.
    • ..could be worse... but out here, renting private affords some luxuries ...we've even been told the Sept dateline isn't critical, and I'd rather move stuff in the cool of winter, than slogging it out in the heat. Recall we were talking about the million dollar view this place has?...that's what he got for it... (won't be so nice when the quarry happens at the back in the future...lol..)... ...cool, I'll stick the wiper motor in a wee box...umm.... the pinny is GLX trim ~ I think that's about as close as it gets to Silo spec when it comes to the S2 pinny...ie; electric mirrors etc etc...dunno about the trip computer/wiring...I do electronics repair, I'd be willing to take a look at it for you. As you saw, all the dash is there in that car..and thinking about it, it'd be easier to pull the whole center section out, rather than just the ashtray and rails, but your call...
