Bee*R Rev Limiter on a non ECU car? can it be done?

[choonga]

Hey all.

I'm looking to get one of the bee*r rev limiters for my sprinter. Can they be installed on a car that does not have an ecu.. such as a 4ac Sprinter...

Thanks!

put your 300 dollars towards a 4age

[jono86]

word.
can be done. but if you drive it properly there is no need for one as you shouldnt hit the limmiter on a 4ac lol

not you can't put it on a standerd sprinter 4ac because it has points but if you put a later carolla electronic distributor on it you could but whats the point its only ever going to be a 4ac

sorry man but not quite

you can put it on your regular 4ac

there is a wire that goes from your dizzy to your negative side of the coil, this wire forces the coil to calapse and thus make your spark. the wire is connected straight to the points setup in your dizzy. if you cut this wire no more spark for your engine = rev limit.

so all you gota do is figure out how the rev limiter works, and make a circuit that cuts this wire when the rpm is reached. either by using a relay or a transistor.

i was going to make a rev limiter for my car (4kc woot:P) just for fun, out of a shift light and a relay, using same principle as above.

i woudlnt go spending your money on a bee-r one, over rated in my opinion, everything they do can be made for ALOT cheaper with the same effect

[choonga]

i'm doing some work to the 4ac i have at the moment. Yes i know its like walking down a dead end alley. I am still on the look out for a 4agze or something. But at the moment i have this 4ac, a worked head, a lumpy as fuck cam and twin webers on a custom manfiold that i can and have put on it. It probably won't put out much power, but i have these things and thought, why not!

So back to putting a Rev Limiter on it. 1. i want a rev limiter if i'm going to be drifting it. 2. th bee*r also has the added OMG LOOK AT ME effect with the flames and backfiring. :lol:

So.... after reading what ke70dave said. I gather, yes, it can be installed onto my car? how else could i go about getting the same effects as the bee*r without buying one?

Thanks.

Rev limit on 4ac/4kc = valve bouncing.

same effect as a rev limiter, but on the cheap is:-

get:

cheap adjustable shift light (seen them on ebay and maybe autobahn/supercheap)
ordinary relay (12V automotive one)

open up up the shift light and find the wires that control the actual light itself, hopefully this is a 12V power source for when its time to "shift". run these wires out of the shift light and run them into the engine bay somewhere.

next find the wire i am talking about from the dizzy-->coil, should be black as its a negative, you might have to experiment with some. it will be the same wire that you use to tell the shift light what RPM the engine is doing i think....either way it is the negative pulse from the dizzy to tell the coil when to fire.

next get this wire and cut it, and put your 12V automotive relay inline with it. use the wires from the shift light to trigger this relay. make sure you wire the relay up in NORMALLY ON mode, so that when the shift light lights up, the relay will close up, thus cutting the wire, and thus "limiting" your engine. then once the rpm has dropped below the desired "shift point" the relay will open back up and ignition will fire as normal.

this is EXACTLY how a bee r one works (cept in cars with coil packs/ignitors they just cut the power to something else to stop the spark from working), except they come with a few extra features, like duration of "limit" (essentially just a capacitor to hold the charge across the relay) and i think they come with something where you can hook it up to your handbrake and "limit" the rpm at a certain rpm for launch starts (drag racing). this is achievable, if you want i can explain it, but its point less i reckon.

if you need any more help with it PM me and i can explain it more in detail if you like with diagrams etc

just don't buy a bee R limiter (they are like 300$ or something stupid??), waste of cash *awaits flamage*

[dr1ft-pig]

a normal realy wouldn't give the same effect would it????

i would think maybe using a flasher can from a blinker setup would be the go as it will turn spark on and off constantly

[ke70dave]

yeah you can do that i spose, not really much difference

it will have the same effect, as it will cut the ignition, then as soon as the rpm drops, it will engage it, then cut it, then it will drop, then engage it...so it will work the same.

[dr1ft-pig]

ahh yep i see

hell yea :2thumbs:

[Hen is a total nutcase]

The BeeR limiter will work.

I read (admittedly in a mag ages ago) that the BeeR works by grounding out the ignition output(s) when the rev limit is reached. Therefore no spark, therefore flames out the exhaust.

You can do the same on the coil on your 4AC (or any other carbed car). The coil negative wire is earthed through the points and sparks when the points open and the wire is no longer earthed. If you wire the BeeR up so that it earths the coil negative wire above the rev limit it will work as normal.

And if you use the above shift light technique, rather than using a relay, use a transistor. They are slightly more complicated to setup, but are smaller and far more reliable when switching often and fast.

Sounds like you just want the flamage and backfiring and not really much else. Don't worry about rev limit if you want to drift with a 4ac, it wont die anyway.

Know any autosparky's? Get him to hook up a switch with a sparkplug in your exhaust and all the rest, so when you hit it it will ignite the raw fuel, same effect but cooler.

That is all.

cut a hole in ur exhaust weld a nut screw in a spark plug wire it up on a switch BINGO! instant fun!

[r3zzz4]

Bingo maybe if you ran it rich all the time, you would need raw fuel delivery aswell to make it REALY worth it haha flame-thrower anyone?

[Benno]

go buy one from jaycar and assemble it, they're about $50 and have the neat led's like the bee*R.
they also have a hysteria adjustment for soft or hard limits

[ke70dave]

the jaycar kit he is talking about is this one

rev limiter (http://www.jaycar.com.au/productView.asp?ID=KC5378&CATID=25&keywords=&SPECIAL=&form=CAT&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=347)

i just found it, thanks brenno for letting me know about that

its heaps cheaper than the way i was describing above, 35$ is a bargain!

[Benno]

I've actually got one with a 4 led(3 green, 1 red) display for the shift point and a adjustable limiter when the red comes on.

I'll be buggered if i can find the kit now, might have been a DSE kit

[rich_86]

group buy???

[Sherlock]

Sorry to bump and old thread, but I've read through this and obviously come to a conclusion, don't waste your money...but I have the chance to get one of these on the cheap so I have a few Q's...

I know the advantages so far
- They limit the Revs so the engine doesn't over rev and essentially die
- They pop off some cool flames n shit :teehee:

But is there anything else I need to know? Disadvantages? E.g. Massive hole in the zorst from flames? :lol:

Thaaanks

Edit: Sorry forgot to mention, running on a stock 4AC, will have a 2 1/4" Exhaust.

[zed x]

pros: can wire to handbrake annd set to a different rev limit (4000rpm) so when handbrakieing you can hold your foot flat to can instant power well letting it off

can wire it to the clutch enabling flat gear changes

can adjust the rev limiter from a constant popping to a massive bang sound with crazy flames lol

look neat and quick and easy way to adjust the rev limit

fun way to de-cat a cat haha

Cons: have been known to kill ceramic turbos

blow out cat's in no time

cannot raise the factory rev limit

ive got one for sale, i bought it for my sil but on the day it arrived i sold the sil - to get money to buy a sprinter woot :)
