Hi all, 

I have bought a Bee R rev limiter ( I know they break engines, its just for a one off event)  and I'm having some serious troubles wiring it into my R34 Gt (NA). So far I have my my yellow wire connected to pin 44 and 45 (tried both) Green is Connected to 46 and my power and ground wires are correct. The car starts and Runs with this set up but does not limit revs regardless of gain or rev 1/2 settings. Ive tried switching the the green and yellow wire and the car would only start if gain was set to 0 and as soon as gain was 1 or more it would stall. Has anyone else had this problem? if so how did you over come it.

Edit; I have just noticed Pin 44 and 45 join a little brown box further down the loom. does this have anything to do with it?

Thanks

  1. Chuck in bin
  2. OR:
  3. Bee-R Website instructions are wrong - they know, Brooksie has told them they're sorting it
  4. Takakaira Website is also wrong - they copied the Bee-R website
These are the correct wiring instructions

WIRING

Yellow Wire - 120' pin on ECU

Green Wire - 1' pin on ECU

Red Wire - 12V IGN pin on ECU

Black Wire - Ground (On PowerFC's you may need to add an extra earth from this pin to the PowerFC chassis for extra earthing).

White Wire - Attaches to the Handbrake On wire that goes to the dash if you want to activate the Launch Control feature

ECU pin outs


R34GTT

Yellow - 44 or 45
Green - 46
Red - 67
Black - 25

R34GTR - I don't have an ECU pinout for this so I can't tell you, hopefully this'll be sorted fairly soon

CONTROL BOX WIRING

White Wire Loop - This activates the 2nd white dial which allows you to set a secondary rev limit which only comes on when the handbrake is on and is mostly used as Launch Control. Cut the loop if you don't want to use it

Grey Wire Loop - Leave this alone, only cut for 4 cylinder cars

Brown Loop - Leave this alone, only cut if you have a rotary engine

CONTROL UNIT

Red Dial - sets normal Engine Rev Limit (see below)

White Dial - sets Handbrake/Launch Control Rev Limit (see Below)

Yellow Dial - Sets the Gain or how big the Bang is (0 = off, 1 = very quiet & F = WW3 image.gif.f8bb9cf6deedcdd2c917f24b3f85ebc4.gif - try a middle setting and adjust to your peference)

The 0-F settings match upto these Revs

0 2500
1 3000
2 3500
3 4000
4 4500
5 5000
6 5500
7 6000
8 6500
9 7000
A 7500
B 8000
C 8500
D 9000
E 9500
F 10000

TESTING & PROBLEMS

Normal Test - With the car warmed up (very important) set the Red Dial to 5, the gain at 9 and the white dial to 3 (only if using the handbrake option). Now without the handbrake on gently rev the car and at 5000rpm the car should start back-firing and the red light on the control unit should flash

Handbrake/Launch Control Test - Put the handbrake on and gently rev the car and at 4000rpm the car should start back-firing and the red light on the control unit should flash.

If it does then everything is set up and you can now adjust the dials to your own preference.

Problems - Car doesn't start - swap the Yellow and Green around (shouldn't happen now the instructions are right)

Hope that sorts everything out..........................................IanH

    • Not sure if you're being serious? I, and all the car people i know, ALWAYS use a torque wrench for wheel nuts. I assumed any car person, apart from tyre centre monkeys with rattle gun in hand, would do it properly.  Anyway, no further reply from me on this unless legit discussion from OP or his query so, over to you, knock yerself out.
    • I was wondering about this. I'll do some research.
    • Why not? Since mines been built, I've used low boost maybe 5 times.
    • Yeah, so widen your search to any Nissan speedo first, then go wider if needed. I will say though, that there is a better than even chance that what I said first will likely come into play. They quite possibly won't come apart without damage. I tried to disassemble a stepper gauge that I wanted to repair. There was no way that needle was coming off the spindle, and I could not see how the spindle would come out of the mechanism behind. Assembled once, never to be disassembled, was my conclusion. Could be the same on the R34 cluster. Failing that - take the cluster to a workshop that specialises in automotive instrument work. There's usually at least one in every Australian city. They'll either be able to do it for you for small cost, or tell you it can't be done. It might be that "it can't be done" unless you follow some arcane procedure, including trickiness to glue it back together or something, that only experienced techs know.
    • Well, given that I, an engineer, almost never bring out the torque wrench to tighten up chassis bolts, despite fully knowing the theory, and instead rely on feel, which I happen to know is exactly how the majority of mechanics do things, should tell you the level of actual peril that exists from not achieving exactly 88 Nm of torque. How about if I just say then that 88Nm is at the lower end of the correct wheel nut torque range? Everyone knows how to tighten a wheel nut, right? And almost no-one ever brings out the torque wrench for that task
