Thread: Any one running the Bee R rev limiter/two step.

Other than it blowing huge flames and making shot gun sounds, does anyone have anything positive to say about this. I am ready to purchase one since my Jim Wolf Ecu doesn't have a rev cut.

Here is a vid of one at 5 gain at 5k I think.

Here is some info and a pic.



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!

yeah im thinking about doing something for a two step launch control and for a harder rev limiter to prevent reving to 12k like ive done before when i broke a gear or an axle. Definetly should keep from popping rockers out. Ill look more into it.

I know the 240 guys are big on these and they work pretty good. They use them for drifting by setting it to say 6500 rev limiter so they can full throttle drift and not have to worry about over rev. I know it works well as ive seen vids of it in use.

how much do these go for

You can find them for the 200 area. I am about to press the buy now button. I think this can be the replacement to the ugly red 6al box.

i am def gonna run one of these

I think everyone should ditch the 6AL and go with this.

Any reason as to why you'd ditch the MSD unit? I know they are cheaper or maybe you don't like the size of the msd unit? I plan to run a two step in my car but planned on going with the msd for other features such as timing retard when using nitrous.

I can get you a n2mb racing WOT box that has 2 step launch control and wot shifting cheaper than that. Actually about to open a group buy on them after I get it installed on my car and make sure everything is kopasetic. It even has software to set the rpm points at whatever you want them to be on the 2 step and the "no lift shift" duration. It can be wired to cut ignition only, fuel only, or both. Pick your poison. It does have a rev limiter. I'll check on it and find out for sure though. Retails for $169 but You can also get just wot shift box or just 2 step at retail for $129. Depending on how many people commit I can get us some decent prices on it.

Quick little tid bit on it...Sorry I know it's hard to read.

Thats the good thing about the Bee R. You do not need an external box to run it. As for retarding the timing, I guess that is where the MSD does come in play, but this seems like a great solution for a rev cut/two step.
