Default How To Add Step 2 Launch Control

I am trying to make my own step 2 launch control but don't know how with the program ECUFLASH. I know Enginuity has a feature for it but their site is down and I know noone who has the program. My brother did it to his EVO VIII but attempted on mines and became clueless. Help?

Teacups has said quite clearly, and I quote:
"There's no version of Enginuity that comes with launch control."

He did mention that it had been tested, and I quote:
"We've tested it, however no ETA at this time and it is not planned for the next release."

So for the time being, if you want 2-step rev limit (launch control) you will need to buy the Bee*R Limiter, or get a COBB AP, or an aftermarket ECU that has it.

The Bee*R is what I will be using, and it is fairly cheap.

the Bee*R is launch control? i thought it was a misfiring system more like anti-lag. or is there even a difference?

I don't even know what a Bee*R is. But the Cobb kills ignition so I don't think I want to try anymore.

A company called gizmo also makes a launch control module and it also allows flat foot shifting. According to the website, it cuts ignition like most other units to achieve the result. It goes for $149 on eBay but I think you have to have the tach they sell to use the LC interface.

Cool, cheers for that. I didn't know of any others apart from the Bee*R limiter that were only ignition cut

I had a squiz at the Gizzmo website, and it said you need the "Gizzmo Tach Recall" shiftlight to operate the "Gizzmo Launch Interface". Basically the tach/shiftlight has the dials required to actualy set the rev limit you want to enforce

I also had a look for places to purchase and found that Apexi USA sell the Gizzmo range of products (see here)

I run the Gizzmo LC and 2 stage shiftlight on my car... keep in mind this is ignition cut 2-step so if your'e shim over bucket still you could potentially run into problems with cracked shims... I never had any problems on my stage 2 ej205, but that's no guarantee you won't!! Also, someone posted above that cobb was ignition cut... to the best of my knowledge cobb is actually fuel cut (which is safer, although way less fun )


Hope that helps

you can get a used UTEC for the same price as those 2 items and have launch control AND flat-foot shifting. i'm actually thinking about doing it for the launch control myself.

yeah, unless you buy the light and launch control interface used... which is what I did. I'd buy Utec though simply because it offers fuel cut if you decide to run that instead of ignition cut

Found a new one almost by accident and it looks great. Cuts both Fuel and spark, is pretty cheap compared to the others and it's less crap to install meaning a more stealth/factory look. I think it allows flat footed shifting as well seeing as how it uses the clutch switch like almost every other type. I may just pick one up.

That is one really nice 2-step launch control unit

I'm sure it will be fine as a a rev limiter - but it will not offer the advantages of an ignition-cut only limiter.

With an ignition-cut only limiter, you have the added bonus of a simple anti-lag system when the excess fuel ignites in the exhaust

This is generally what most are seeking in a two-step, so when they are hitting the lower limiter ready to launch, they start to build boost.

It doesn't work like those proper anti-lag systems, but it does a good enough job of assisting to build a few pounds of boost while stationary - a bonus at the track for sure

Check out THIS youtube video, it shows the Cobb AP ignition-cut launch control on a wrx which is building about 6psi while stationary :P

That's fuel cut launch control actually and it's on my friends 2005 sti, not a wrx... Both ignition and fuel cut will build boost at idle but ignition cut tend to build a touch more...

Basically the trade off is as follows:



Fuel cut: safe for valvetrain but builds marginally less boost

Ignition cut: builds marginally more boost, shoots sweet fireballs, can damage the valvetrain/crack shims



(I personally have had good luck with my ignition cut system and am very happy with it.. however this is not everyone's experience...)

Maybe COBB will develop (if they haven't started it already) a new software version that would allow one to run whichever type of LC or FFS they choose... Ignition cut, fuel cut, or both. I am a APv1 owner and have been debating over if I should pick up a used APv2 or not. I'm not sure if there are any huge benefits of the APv2 as far as OTS maps go but if COBB continues to develop new features such as LC, FFS, and a type of Anti-Lag, that may push me more towards getting one.

Looks like FFS stands for something completely different on this forum compared to the Australian WRX forum I spend my time on.

I'm not sure exactly what approach Ecutek use for LC but I was seeing up to 10 psi boost with the engine under zero load. It was quite a soft limiter with no backfiring so I assume it was both fuel and ignition cut. Worked pretty well.

....then I got fed up with ridiculous retuning charges so I got a new ECU and a Tactrix cable.

BTW you guys are spoiled for choice over there. I'm very jealous.

I haven't bothered yet. I'm running a VF34 as an interim setup. Once I get all the twin-scroll bits together then I'll start concentrating on getting the tune just right. I'm getting some good help from a guy who helped out with the STis that won Targa Tasmania.

Cheers,
Ben

Actually it's part of an internet tuning or tuning package that can be purchased from me. You have the option of $60 to cover 30 days of internet tuning and support to follow, which, yes does include the flat foot shifting.

There isn't one big secret, there are quite a few parameters that have to be set-up correctly in order to achieve this.

So is that only for the "no lift shift" or can you also do launch control via internet tuning?

launch control is not something that is available with open source as of right now, no lift shift is the only addition I can put on your tune. My honest opinion on launch control is that it's not something that is needed until you get into cars with GT35's, GT40's and big turbos of that nature. At that point I feel it can be a benefit.

I've found that most of the time I can launch better myself than a car running a launch control system.
