I've had a hard time finding a easy to understand write-up on the Bee*R Rev Limiter / Power Builder, install. So decided to do a guide once i figured it out. Its very easy but if you dont know what wires to connect it to then it can be confusing. i fitted it in a 97 Kouki with s13 black top. more information can be found in the link below.


Reference and full wiring can be found here:
Bee-R Rev limiter fitting guide - Drifting forum - Driftworks





ECU:




First unplug your battery.

Then you want to find a mounting place for it. I put it on top of my steering column.
.
Route it to the ECU:
.
.
We color match the wires from the Bee-R to the ones in the diagram:
.
It will look something like this: Notice the last wires was not finished yet in the pic
.

And dont forget to cover the connections with either shrink wrap or electrical tape. Once wrapped, connect the battery. Start the car up (Car will not start if Green and yellow wire on ECU are connected wrong way round). set the red knob on the left for the rev limiter.
settin 0 is 2500 RPM and settin F is 10,000 RPM

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


REV1 is the normal rev limit and REV2 is the limit when Handbrake/switch is engaged used
for launch control set up - (see in above link) i didnt care for it and my bee r was used and didnt have the white wire to connect to Ebrake.


GAIN (3rd knob) sets the frequency and length of cut. the lower the number the quicker the cut. e.g. 1 = bababababa F= BANG!!!......BANG!!!...... IF you set the GAIN to 0 the limiter wil not function.


This tutorial can be used for s14's with s13 sr. i used the N02 diagram from the link above. Depending on your ECU you might have to use the N01 diagram.

Hopefully it helps others.
