so is this wire that youre all cuting coming directly from the brake switch?

similar to andy's theory, just hook the park brake line directly up to the ECU brake activation so the park brake activates it instead

This would work fine but harder to implement since you now have to find 2 wires & afaik the handbrake doesn't have a connection to the ECU. Also, the handbrake wire is prob an earth but what is the one we cut? It could well be a feed from the brake lights, ie 12V, so one of it's purposes is to let us know when the brake lights are out, not just kill our launching fun :P .

I think a simple switch to reconnect the circuit is simplest & possibly less problematic in long run. It can be mounted close to ECU (even in glovebox or top cubby near DVD) if you don't want to run wires across to driver's side.

+1 on that.....I ran the momentary switch down in the slot below the Cig lighter.

did you notice a difference in drivability at all though craig?

assuming mines shown a light i dont think ive noticed any change at all

nup....noticed nothing...nothing at all!....could still do a stall and launch at 20PSI bagging all 4's right through 1st!

yeh i dont think im gonna bother with a switch..

my AFR's seem fine, i havent noticed any drawbacks over the past few weeks ive had it.

i have noticed the car seems to be pulling alot harder, but thats probably coz i just serviced it.

meh...

whats your stall at?EDIT: actually whats everyones stall at? if they were to sit on the brake and accelerator, what to the revs read(before spinning)

at 3000rpm I cannot hold it any longer.....I have to let it go....that's at 19-20PSI.......if it's in 2WD I need to let it go a lot earlier!

yeh mines at around 2500-2700.. my tires wont spin up at stall even at 10 psi.

if its when or really cold we have another story but that might be the brake bias or the pzeros

Jethro, can you confirm and let me know.. i have a feeling all(some) the stall converters are varied now..

Yep, around 2700-3000rpm, mine is slowly churning both rear tyres and sliding the back end to one side in the lane. LSD FTW!

Let it go; solid chirp and it f**ks the f**k off out of there!:banana:

do you have four pot fronts?

do you have four pot fronts?

In a box under my workbench? Yes. On the car? Not yet.pinch.gif

Too many projects going on ATM, will have to get back to my Big Brake conversion soon. Do have to stand on them fairly hard too, and no wire snipping yet.

I'd certainly like a bit of Jetwreck's turning all 4 in first though...

Shouldn't make a difference from standstill should it?

yours wont because you have rears..

but the brake bias changes with the four pot fronts(mainly GTR32 conversion)

I think anyway.. im sure cam will come and correct me.

looks like it will make it easier to spin up the rears at stall as you dont have to stand on the brakes as much to hold the front.

Aaron try this.

Stall up in 2WD......when it starts spinning let it go and then flick your attessa back on and it should lock up the fronts launch like a mofo!

I did a couple of back to back tests with a mate the other night on a private road and this was by far the quickest way to launch my car.....sub 5's!

dont have a switch yet.. and surely thats not good for the attessa system right??

and as i said, these tyre will JUST start to slip but wont spin at stall, they're still new and really soft and sticky.. sometimes i wish i had nankangs lol..

i reckon i'll get em spinning once i do the brakes, i wont have to stand on em as much

      Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL

      Could be falling edge/rising edge is set wrong. Are you getting sync errors?

      Jacks that fit under GTR lips that can reach the subframe?

      By joshuaho96 · Posted

      On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.

      Mistakes were made, my R34 Story

      Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
