There is a fitting guide available for the Bee-R rev limiters on the Bee-R website, but it's all in Japanese which poses a problem for the non Japanese fluent amongst us. Being the ever helpful chap he is, Maz has translated this into English, so here it is: OK so here it is... everything i managed to work out in terms of fitting my bee-racing limiter http://www.geocities.jp/beer_imai_sp...evlimitter.pdf This is the instuctions in japanese please use it to work out the correct wiring plug arrangement for your car. For CA18DET/Zenki S14, use diagram N01 For Kouki S14 / S15, use diagram N02 Red top SR20DET user should use diagram N02 also. These pictures are taken from the Bee-Racing website and translated into english by me: Remove battery earth {} Remove ECU from location in passenger footwell {} Remove connecting plug from ECU {} At this point, you should double check that your ECU plug is correct for the wiring diagram you intend to use. (N01 or N02) The number of pins should be 16,20,20,20 for N01 or 16,14,16,18 for N02 (looking at the plug from behind like in the picture) Splice each wire into the correct position. Bee-racing reecommend the use of connectors. {} {} {} The Wiring diagram according to the instructions is as follows: N01: (from left to right) Yellow, Green, Red, Black (please refer to diagram for exact pin locations. N02: (from left to right) Yellow, Green, Red, Black (please refer to diagram for pin locations. WARNING: When i fitted mine, I found that the green and yellow wires where the wrong way round on my Kouki S14. I have heard that many others have had the same problem. According to Bee-racing: Red wire: 12V+ Black wire: Earth Yellow wire: RPM Signal Green wire: Ignition signal. So if someone can confirm the correct pins for RPM signal and Ignition signal. that would be great. Those people who have an AVCR/SAFC etc.. should be able to work out their RPM wire easily too. Refit the plug to the ECU {} Cut the appropriate wire for your engine {} 4Cyl = Cut Grey Wire Rotary Engines: Cut Brown Wire 6Cyl = leave all wires intact. The white wire is used to set REV2 RPM. Bee-R reccomend that you use this as a launch controller by attaching the wire to your handbrake. I attached my wire to the handbrake but use it to keep the revs up but not too high whilst on the handbrake mid drift. {} {} {} Refit ECU to mounting position {} Confirm that all wires are connected properly, then reconnect battery {} Start the car up (Car will not start if Green and yellow wire on ECU are connected wrong way round) Make sure that both Rev1 adn Rev2 are set to 0 and rev the car and confirm that it limits at 2500rpm {} change rev1 and rev 2 settings and confirm that the limit changes when handbrake/switch is engaged. {} Mount the unit to a place of your liking {} NOTES: Most limiters are Type B. this means that the variable limit is: 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. GAIN 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. There has been potential problems reported with Power FC users. The earth wiring may need to be reviewed for in some cases... Hope that helps, Maz {}
