Does a Rx7 have a REV Limiter.

 

Or maybe that is not what I'm asking. Like a device that controls how high you rev so you dont blow your engine.

 

Yes, in my S4 I encounter Fuel Cut at 7800rpm.

 

Why wouldn't the rx-7 have one?

 

Yes they do indeed have a rev limiter in the ecu. On my old s5 N/A it would rev out to 9,011 RPMs according to the SAFC.

There is a lil buzzer that goes off aswell when you are hitting redline.

 

does no one use "search" anymore?

 

When has anyone searched???

 

Well I expect out of the new folks but not from someone with over 700 posts.

 

never heard of it. . .I gotta do my research more I guess. still learnin guys!

 

let the guy ask what he wants... if you dont want to answer the question just done... i think its wierd for people to take the time and type in seach when they can reply with the yes or no...

 

Kinda like this.

If so will it damage the engine.
I dont think it will because it clears the carbon out of the engine doesn't it.

 

anything can harm an engine, but in the case of removing carbon from the rotor or chamber walls, no matter how it happens, can most definitely harm the engine. NOT a guarantee to harm it, but it's possible. carbon deposits are cruel to rotaries and the water treatment is often said to be the safest way to get rid of carbon deposits without tearing the motor apart.

 

Well i just wanted to know if that vid i put up there is a rev limiter.

 

With and without a rev limiter on an FC....

I always use search...

 

i think its actually a device used in drag racing. its supposed to hold a certain rpm for the correct launch. i read a thread about it about a year ago

 

It's called a 2-step rev limiter. It only works when the clutch is all the way in and the car is not moving. Once the car is moving the regular rev limiter will work. Basically it is a controled miss fire. It cuts ignition insted of fuel so the excess unburnt fuel is ignited in the turbo manifold spooling the turbo. It is used to get full boost off free revs, and it eats turbine wheels.

 

Here to sum it down this is what would happen. Your car would be parked and it would also be running. What you would do is just slam on the gas and it would not move it would be in neutral the whole time. What the car would only do is just red line and would basically go rununununununununununununununun. I hope this kinda helped.

 

Mine revs right to the moon!

 

Oh well that kinda doesn't help.

 

The rtek 2.0 for the n/a will let you change your rev limit

 

8200 I believe on S4 ECUs. Both S4 and S5 apply a fuel cut to one of the rotors. I would have to check but I believe its on the front rotor.

 

haltech spark cut for ya.

 

Oh ok well I'll find out when I build my engine here soon.
