new toy for u rev

What is REV LIMITER?

The unique REV LIMITER from Power Builder Bee Racing is a device where a driver can use to prevent a vehicle's engine from being over rev. All parameter adjustments on this device can be made on the fly from the driver's seat. This REV LIMITER is achieved by cutting off the ignition at a preset RPM limit, and by re-routing a fuel dump. An aural feedback of back fire popping sound from the exhaust muffler is the result followed by a fantastic visual of fire coming out from the exhaust muffler tip. This aural & visual feedback are very similar to those experienced in the fully race-tuned race cars .

Is it really safe to use REV LIMITER?

The rev limiter in the vehicle is controlled by the factory ECU by instructing the fuel pump to immediately stop the fuel supply to the engine. Such immediate forced fuel cut is not advisable if it happens frequently as it has damaging effects to the engine in the long run. On the other hand, with Power Builder Bee Racing's REV LIMITER, it actually cut off the engine ignition without stopping the fuel supply to the engine. With this function, over rev limit damage to the engine is prevented, and is a safer way in the long run when the engine is over revved past it recommended RPM limits.

Can I install by myself?

The REV LIMITER device can be DIY installed. It has four wires of different colors that needs to be connected to the vehicle's ECU. Please refer to installation manual for detail instructions.

My car using POWER FC. Can I install this REV LIMITER?

A earth grounding issue has to be resolved if a vehicle is fitted with an aftermarket APEXi Power FC unit. This grounding issue is due to a lack of a ground terminal in the APEXi unit. The REV LIMITER uses the ground signal to cut off the ignition signal from the ECU. Since APEXi Power FC is a piggy back computer, and manipulates the original engine parameters' signals from the ECU before re-routing these modified signals to the vehicle individual engine components, a separate grounding signal is required from the APEXi Power FC. Once this grounding issue has been resolved, the REV LIMITER will be able to function as it is intended to be.

When can a car get the effect of back fire with popping sound from the exhaust muffler?

The visual effect of having fire spitting out from the exhaust muffler every time there is a rev cut when the REV LIMITER is installed is not guaranteed by Bee Racing. This is due to the fact that fire would only result during high engine revving, and when the exhaust muffler is warm up, and also when the vehicle exhaust system is without a catalytic converter. Basically, the unrestricted vaporized fuel supply when ignition is cut off is lighted off when it mixes with the air from the engine air intake in the hot exhaust system. The hot temperature from the exhaust system is the catalyst that ignites the air-fuel combination in the absence of the ignition sparks.

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok thanks..that was my second question if i can somehow bypass this even with Nistune(that is all i have right now...aparat from stock ECU. So with some aftemarket it can by "bypassed" or make it work?  I know there is Link or Haltech (mainly used). We have ECUmaster here so i will gather some info about it.

      Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.

      Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that
