Has anyone succefully installed a bee-r Rev Limiter on a vq30? The VQ30 is listed in the compatibility list, but I can't get it to kill ignition when limit is hit.

must be too JDM

did you change out ECUs ??? if so ... which ECU did you get

also ... you're a 99'r ... may make a difference

How did you wire it up?

..you dont have an OEM rev limiter? i thought the ECU had one... thats why people what the Jim Wolf ECU flash to get rid of it...

pmohr

No one completely gets rid of the rev limiter, just raise it up. Perhaps you're thinking of the speed limiter?

In any case, this is just a 2-step.

its a 2 stage launch limiter. idid wire it up according to 99 ecu pin out...i'm confused as to why it won't work.

The bee-r rev limiter cuts ignition as opposed to fuel and the 2 stage rev limiter comes in handy when waiting at a tree....

wired up as follows:

bee-r - ecu - pin#
red wire - 12+ power - Pin#31
black wire - ground - pin#32
yellow wire - 1deg crank pos - Pin#49 (Input signal)
green wire - 120deg/180deg crank REF - Pin 46/47 (output signal)

instructions are all in japanese so its difficult to get translated, but someone did a writeup on a skyline forum and says all th nissans should be wired up the sam. Using the Crank sensor for input and output.

Where did you get the pinout from, the FSM? FWIW, the 99 FSM ECU pinout is incorrect.

You say crank ref for the green wire, but you're wiring it up to the CPS? CKPS REF is 44/48, not 46/47 (CPS).

That's what's wrong with the 99 ECU pinout in the FSM. Pin#44(CRANK REF) was moved to Pin#46/47. This was confirmed by DandyMax. Its also confirmed in Dandy's Greddy EU installation writeup on VQPower.org.

I thought to myself....maybe I had one of those 99s with "correct" pinouts. So I also wired up the green to the #44Pin and when I started the car....super rough idle.

We were able to get the bee-r to function on a RB series motor. I noticed on the wiring schematics...the difference coils get signal from the ECU directly. The RB20 we got working gets its signal from the ignitor chip. Does the VQ also fire its coils via an ignitor chip? If not, this could be why it can't cut spark. Maybe the signal from the CKPS isn't compatible?

I think Pmohr hit it on the head. Make sure you are using the corrct sensor. I understand 99' ECUs are different (for several reasons) and it could be that the pinning for the RB and Skyline are different for their givven ECU.

This is from a post that Kevlo made a while ago ....

This picture is from the FSM, page 99 (but I think this may be for a 98' )

from Dandy's write up for the Greddy EU install, the 99 REF pin is 46 not 44. There has been several comments throughout the org that they have experienced this discrepancy.

bump for some help?

the cefiro vq30de is listed as one of the compatible engines...so shouldn't the maxima be?

here's an english break down of wire installation.

mymaxi41691

Did you ever get the rev limiter working?

bohead

iTrader: (9)

Nope....worked on it for months and finally gave up...

mymaxi41691

If its still in good condition, will you sell it?

why don't you just get an EU?

iTrader: (19)

No.

I think that was your problem.

Our revlimiter is fuel controlled. Spark is still there.

wirelessdude04

iTrader: (24)

why?

Kevlo911

iTrader: (36)

What? What do you mean why?

It is a fuel controlled limit as in when it hits 6500 the ecu cuts fuel. If it were an ignition controlled limit, it would cut spark.

He's trying to wire up a 2-step to cut the ignition at an RPM below the stock rev limit. I guess the difference between the RB's ignition setup and the VQ's is why he can get it to work with one and not the other.

does this help at all? looks like they used RPM & ignition signals. so does that mean we use the tach wire and CPS wire?

For the 'ignition signal', you could try the CKPS POS, CKPS REF, and CPS. Hell, run it to a multipole relay and tie that in to all of the coil signal wires.

That would work, but it would be kind of hackish IMO.

I tried all three. One would cause horrible idle, and the other two wouldn't even start.
