Here you go, borrowed from newera:

This is Bee*R’s popular two-stage ignition cutting rev-limiter. It is used to prevent damage arising from over-revving your engine. Part of the reason for its popularity is the large flames and loud bangs it produces from the exhaust when active!

The way in which it works differs from the factory rev limiter in that it is an ignition cut, as opposed to a fuel cut. The reason for this is because if an engine (particularly turbocharged) regularly hits a fuel-cut rev limit (such as in high performance driving, or particularly drifting) engine damage can arise due to the lean condition produced when the original ECU shuts off the fuel pump. The BEE*R rev-limiter allows fuel to pass into the engine still, limiting engine speed by disabling the ignition signal. The Bee*R rev limiter is fully adjustable in 500rpm increments, for safety reasons allowing only a lower rev-limit to be configured than standard. If you have spent a lot of money tuning your engine, or are running at high RPM’s for extended periods of time, it could be recommended to run a lower rev-limit to prolong engine life. Both Formula 1 and JGTC cars use ignition cutting rev limiters, so it is a fully race proven concept.

The Bee*R can also be used as a “two stage rev limiter”, as an aid for launching your car. The Bee*R is configurable for two different rev-limits. A lower rev limit can be activated by a switch, the handbrake switch often being used. This configurable lower limit, can be set to the optimum RPM to launch your particular car from in 500rpm increments. When the handbrake is released, the usual rev limit comes into action, allowing quick launches, and full performance down the strip.

The Bee*R rev-limiter has another final neat feature. The gain control knob allows you to adjust the frequency of the ignition cut. This in turn changes the frequency and sound of the flames and bangs from your exhaust!

im sure running lots of fuel through an engine with ignition cut at high revs isnt good,the fuel ignites in the exhaust and can blow the welds on an exhaust,and thats supposed to be good????

well so you can actually set your high rpm limiter to suit yourself?

The best thing with it is for drifting you canbring your rev limit down to take the stress off the engine.

cheers

Apparently you need to splice in an extra earth though. Don't ask me why...

oppossed to a fuel cut which will lean out your mixture and just burn a hole straight through a piston......

mmm wonder which one I'd prefer

Basically hitting any limiter repeatedly isn't big, clever or going to do your engine any good in the long run. The Bee*R just happens to give a more dramatic by product, in the form of bangs and flamage, than the factory feul cut system.

Used in moderation i think it's a good bit of kit and that is my final word on the matter! :)
