What additional wiring is required to enable and run anti-lag & launch control on my 2004 sti?
Currently running open-source so guessing a simple switch for each function and possible a clutch micro switch.
Any help appreciated.
Thanks.

As far as I know 2 additional wires for the AL through a switch

LC can me mapped in to a set rpm and doesn't need a switch, clutch in, put it in gear and foot down and it will hold at set limit

as above, if you want flat foot shifting then a clutch switch is needed. LC would be always "on" but you don't notice it until you try to use full throttle below the launch speed (at which point revs will hold at the launch value instead of banging the limiter).

Antilag would normally be on a switch and just knock it on/off as needed.

What rom are you using for the antilag?

carberry rom is most likely candidate for 16bit cars (bugs/blobs), older ones would be ESL with the motorsport pack.

Again thanks for the info. This rom availible at rom raider?

it is yes, but it's not plug and play - the default map is for a JDM group N car so nothing can be used, you have to set everything up to run your standard engine and properly tune the fuelling with a wideband o2. If it's your first attempt then better to spend £££ and get it professionally done.

Meaning all tables within the map are different ? As an example on evo tephra roms can be loaded and most of the critical tables can be copied and rescaled to suit obviously boost, fuel, knock checked afterwards

yes you'll have to check every table one by one - the default setup is MAP based but you can switch some of the tables back to load based and use the MAF sensor if you want (though the MAF scaling isn't the same so you need a wideband to tune it in).

sbn1979

Yes I have experience with retuning the maf on evos, that's quite good that you can select load based or map based from stock

Should of included a little more info really.
The engine is in this



Running an MDX321T amongst a few other mods to the motor.
It's been remapped by Duncan at RaceDynamix and is going for a tweak later on this year so would like to get anti lag and launch set up for a bit of drag racing.
Am I right in assuming a standard Subaru has a switch on the clutch pedal?

Thanks Ian.

2.5's have a clutch switch, 2.0's wouldn't but you can use a clutch switch off a 2.5 or a brake switch on top of the clutch pedal to get it wired in.

That looks pretty funky, any vids of it?

ianbott

Thanks for the reply. I really need to speak to Duncan but don't like bothering him as I know he's always snowed under.

I have a couple old Vids on YouTube but nothing recent.
Here's a little run down the strip with the old vf35 turbo.
