As im not one for cutting up factory wires and get plug in parts. It has come time to bite the bullet and do the brake cut mod. I am looking at doing it another way than what has been discussed previously. As my car has cruise control im looking at finding the wires associated with the on off switch on steering wheel cutting and terminating wire on the body side of ecu and connecting ecu wire to whichever cruise control wire becomes active when switch is turned on. If that does not work i have a switch i can solder in and run it to glove box

Just did it with a normal switch. On thinking about cruise control on off switch i would be limited to 30% throttle for the whole duration if i used the cruise control on a long drive may have been good for fuel consumption but i will never know

So have you done a test launch yet?

Watched the mighty car mods episode 12 of the double unicorn build. It touched base about the throttle restriction due to the atessa system in the wc's. I wonder if it's the same for us as we use that system? It was along the lines of g sensor and voltage sending info to the atessa which would tell the ecu how much power to send to the tranny etc..

There may be a big smile on your face. There definitely was on mine. Takes a while to stall up but it does happen.

Till about 3 weeks ago I didn't bother stalling up for more than 1-2 seconds , have been and still am very happy with general pedal response coming of the brakes. However bout 3 weeks ago I was waiting at a very tricky roundabout and stalled up for longer with foot flat ...... damn!! the grin I had! back end lost traction front scrambled for grip and the darn thing shot off like never before.

Car is stock except constant high boost, brake mod and trans cooler. This of course has resulted in a special kitty being formed for serious mods to happen. It is (to me anyway) exceptional how well these things get off the line.

Yep well worth the back cramps leaning in to the firewall, cutting and connecting the wires.

It's surprising how lazy Nissan tuned this car given the weight of the thing.

At least they gave it decent factory boost.

Even my wife loves it more now after she drove it through the forests of Durras lakes with the brake cut switched off.

Good little spot here for a switch, in the passenger side utility compartment.

Towards the back of the compartment , there's plenty of clearance behind for the mech.

Very easy piece of trim to remove, 2 screws then jiggle out.

Better than glovebox I think , less chance of getting broken.

I think my tyres are wearing out quicker all a sudden ;)

Dragging an old topic up. 

FYI, I have an AR-X that is 100% standard and I can get it to stall up on the brake to 3200rpm no problems, to the point that the rears start to spin. To my knowledge the mod hasn't been done as there are no CEL codes. 

Not too sure on how much boost its making but it leaves hard off the brake with no hesitation.

    • Hi all, I need to get this HKS SLD attached to my stock ECU because I've now got the German autobahn and faster European circuits to contend with.  The car is a manual 2dr ER34 with an AT ECU and I've realised the AT ECU has two pins for speed sensor signals: Pin 29: Vehicle speed sensor signal (Vehicle speed sensor 2) Pin *58: Output shaft rotation sensor signal (Vehicle speed sensor 1) - *RB25DET A/T model only Before I go butchering this harness, is anyone sure of which pin is the correct one for signal adjustment? The attached document from HKS indicates pin 29 but I found this situation mentioned in the following thread on a different forum (R34 GTT Auto Trans Speed Cut Problem | Zerotohundred) mentioning pin 58 needing to be altered by member zephuros, albeit it seems to be for an RSM-GP and the info appears to be old.  R34_All_Workshop_Manual-pages-2.pdf R34_All_Workshop_Manual-pages-3.pdf R34_All_Workshop_Manual-pages-1.pdf HKS SLD Vehicle Pin out P59-P70 ER34-pages.pdf

    • What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
