Sort of worked...

Aaron and I went for a squirt today, he looked at the gauges while I drove. We found my ecu definitely opens the throttle 100% at launch, but only if the brake was off for a second or two beforehand.

I looked at the ECU diagram and found the brake pedal input wire, not knowing if it would put the car in limp mode or if the brake lights would work, I snipped the wire and backed the car out.

The brake lights worked, and now I had 100% throttle at stall. A drive told me the abs still operated and the takeoff was much better, with the car hitting the 4000 rpm stall limit off the line with little effort.

I will let you know how the car drives over the next few days and if there are any side effects but for now it looks like Pipster pointed us toward the holy grail. :cheers:

Yep and can't believe how simple It really was obviously scotts is running off a built box which means I'm also testing it out for the next few day on the stock box to see if it handles. Scott now has an advantage with the high stall.. On my gbox it's improved a little but because I have a 2000rpm stall I can't do much ATM. But In saying that I can now boost up to 8-9psi on stall with 100% throttle and launch the bastard much better than before. I cant believe we did it, hopefully this will save us over $1000 each by not having To go gzone or nismo anymore!

Woohooo, that's brilliant !

I'll give that a go myself. Will do the before & after tests under same conditions of course, to try & take the 'subjectiveness' out of the equation.

I love low (or zero) cost solutions that give great results. No one can be dissapointed hey

If you want to try it, its pin 55 on the ecu. Its a pink wire with a blue line.(around the middle of the plug.) Just make sure you tape up both snipped ends well. :thumbsup:

(Dont hold me responsible if you damage anything please.) lol.

i rekon the nismo already has this out of the box thats probably why we have better throttle response........

but this is a shit loads cheaper lol

can you confirm this by getting hold of an informeter and stalling it up, before chopping the wire?

would be interesting to know, as i know andys impul is only doing 36% on stall as standard

his is KNOWN to have the throttle limit.

are you guys 100% sure there IS a performance increase?

heres my theory, the informeter is reading the throttle input from your foot. the ECU limits THAT signal to 38% (or whatever) due to its programming.

i have an informeter mate, ill be driving to work tomorrow so ill check it out in the back streets. wont be chopping any wires yet

yeh because before when scott would stall, it would hold him at 2000ish RPM,, now it limits him to his high stall converter.. which means the extra opening has increased, i also noticed a 5psi increase from where it was before for mee..

im sure he did lol

im glad we all worked together to get past this problem :)

now craig and i cant son of rajab our nismo all over you guys :(

Does that mean if this works out everyone gets membership to the awesome forum? :nyaanyaa:

im sure he did lol

Nismo awesome is still awesome; but free awesome is the awesomest kind of awesome.:thumbsup:

'Cept for boobies...:thumbsup:

    • It would be different if the sealant hadn't started to peel up with gaps in the glue about ~6cm and bigger in some areas. I would much prefer not having to do the work take them off the car . However, the filler the owner put in the roof rack mount cavities has shrunk and begun to crack on the rail delete panels. I cant trust that to hold off moisture ingress especially where I live. Not only that but I have faded paint on as well as on either side of these panels, so they would need to come off to give the roofline a proper respray. My goal is to get in there and put a healthy amount of epoxy instead of panel filler/bog and potentially skin with carbon fiber. I have 2 spare rolls from an old motorcycle fairing project from a few years back and I think it'd be a nice touch on a black stag.  I've seen some threads where people replace their roof rack delete with a welded in sheet metal part. But has anyone re-worked the roof rails themselves? It seems like there is a lot of volume there to add in some threads and maybe a keyway for a quick(er) release roof rack system. Not afraid to mill something out if I have to. It would be cool to have a cross bar only setup. That way I can keep the sleek roofline that would accept a couple bolts to gain back that extra utility  3D print some snazzy covers to hide the threaded section to be thorough and keep things covered when not using the rack. 
    • Probably not. A workshop grade scantool is my go to for proper Consult interrogation. Any workshop grade tool should do it. Just go to a workshop.
    • In my head it does make sense to be a fuel problem since that is what I touched when cleaning the system. When I was testing with the fuel pressure gauge, the pressure was constantly 2.5 bar with the FPR vacuum removed. When stalling, the pressure was going up to 3.0 bar (which is how it should be on ignition).
    • ECUtalk pages don't mention they support the ABS computer (consult port has more than one CAN), so you might just need a different scan tool. But, I would expect ABS is a different light to the brake warning/handbrake light, do you see an ABS light come on for a few seconds when you turn the key from ACC to IGN? But since you said: I'd have a look at the ABS sensors in the rear hubs to make sure they are not damaged, disconnected etc.
    • OK, if it idles at 1000+ with the AAC, its not an idle airflow problem. The cold start valve just gives extra air when the engine is cold, but you have enough air without it to idle at 1000. I think you are back to a fuel problem, sorry. Can you see the fuel pressure staying constant or does it drop as the revs drop to a stall?
