Just picked up my R33 S2 on the weekend from a long distance purchase and the seller did not mention this item was in the car at all, I was all for ripping it out thinking it was only for people who could not change gears at the right time, untill I read this thread :whistling:

What a cool device.....

Unfortunately for me it did not come with any destructions, can anyone point me to a Website that has a downloadable User manual? If not, can anyone upload a scanned copy of there's? That would be appreciated, or even a basic instruction of use? I'd really like to get the launch control sussed.

Cheers

Its pretty simple to use dude. You have the two settings, REV1 and REV2. REV1 is your normal rev limiter so you set that to what you want it to be and leave it (obviously this needs to be a few hundred RPM less than your factory limiter). As its a pretty basic design you will need to use trial and error to find the correct adjustment for the setting. REV2 is your launch rev limiter (ie only active when your handbrake is up, assuming they connected the switch) so you set this to a nice sweet torquey spot in the rev range.

Gain is just the frequency of the cuts...no idea which way is which but one will be long loud bangs and the other short sweet pops.

ps, Im not 100% if I got the two settings the right way away, ie REV1 could be launch limiter and REV2 could be normal...you will figure it out.

I'm currently getting one of these fitted in my car and of course no instruction so i've done a bit of research for the r33 rb25

i'm about 95% sure i've got it figured

okay here goes:

ECU ____________________ Bee*R

pin 41(green/black) - yellow wire cas 120 signal

pin 42(green/yellow) - green wire cas 1 signal

pin 49(white) - red wire 12v

pin 50(black) - black wire (earth)

the white wire is for the second limiter and is commonly put to the hand brake

Red wire: 12V+

Black wire: Earth

Yellow wire: RPM Signal

Green wire: Ignition signal

now I've concluded to this from scrolling through the several japanese instructions and comparing it back to the r33 rb25 workshop

now if i've got anything wrong please let me know

cheers

I'll be hooking up a switch to the clutch pedal to allow launch control and flat shift ability.

IE. When you hit the clutch, the Rev-Limiter drops spark to attempt to go back to say 4500rpm......

Keep right foot on loud pedal.

Change gear, drop clutch and bang, off you go again.

I've driven an R34 GTR with this set up through the Motec and the changes are so smooth you wouldn't believe it. and Lightening fast.

Has anybody actually had theirs fitted and is it working?

I had a look at the little dials, and it has numbers around the base, and the dial keeps clicking around.

How accurate can you get the rev limit point?

How many RPM between each click..... ?

    • Yeah they charge a little extra for mods , last year I noted no mods but I did have an exhaust fitted after that so  better to let them know cause these kinds of things can cause the policy to be void if you ever need to claim.
    • Hello, just just bought an 1999 enr34 with a stock rb25neo and I'm looking to upgrade the engine to 500whp I know some basic things but wondering if there are things I'll need to do to upgrade the stock block and all the bits and pieces to achieve this.
    • Thanks everyone for the replies and suggestions. Got the seats out (hoping I could find some existing grommets but no such luck). By tapping and measuring etc. I could figure out where I could drill through if needed. But first I borrowed an inspection camera and managed to go through factory holes in the chassis rail and could see that the captive nut was holding steady which is why it could retighten. So it was indeed a stripped section of thread, so I applied downforce by levering the bolt head with a screwdriver and went slowly back and forth until it came out. Camera helped a lot cos I could monitor that the captive nut was holding tight. Now I just have one very seized main subframe nut to tackle 馃槄
    • BOVs do have a purpose, if you ever log pressure before and after the throttle body, you will see a spike pre throttle on lift off from a WOT condition. Enough to bend throttle blades / damage e-throttle motors or simple assist in blowing off cooler pipes. FWIW, the above on really applies to those running at least 2 bar of boost. OP shouldn't have an issue, on the other hand, here are some videos of my shit box over a decade ago with some succulent dose with the airbox on and off. That shit box is unrecognisable these days 馃珷    
    • I've tried all different combinations of BOVs/ no BOV and stock bypass valves over the years, on gear changes the stock bypass valve seems to get the car back on boost quicker because in part the turbos wheel speed isn't being slowed down by reversion, although they have issues holding boost much over the stock setting. Most aftermarket BOVs you can adjust the spring, tighter will make it open later and close sooner, but in my experience it'll cause a bit of flutter at low load/rpm anyway. I've also got some input into this whole no bov causing turbo wear, never had an issue on any on my turbos HOWEVER, I got my R33 GTST with 200k kms on it, with from what I can see still has the original turbo, no lateral shaft play but has about 4-5mm of play in and out which to me seems like a worn thrust bearing from years (100-150k kms?) of turbo flutter running no bov, so maybe there is some truth to it in the long run. But that'll never stop me loving the Stutututu while I have the car.   OP just wants to know if he can run a atmo vented BOV with no major issues and the answer is YES, plenty of people do it, there's no harm in installing it and seeing how it runs before spending $$$ on an aftermarket ecu, last time I bought a Nistune it was $2400 for install and a tune , unsure of todays prices but you get me. Crazy money to spend just to fix the minor inconvenience of stalling that can be overcome by letting the revs come down to near idle before putting the clutch in or a little bit of throttle to avoid it. You're better off leaving the ecu and tune for after a bigger turbo/injectors have been installed to take full advantage of the tune and get your moneys worth.   Let OP have his Whoosh sound without trying to break his bank haha
