DIY Rev limiter

[chrisarmo86]

Found this while i was looking for some diy projects, really want to make one now. Have googled like crazy but cant find a tutorial or schematic anywhere. Anyone know a thing or two? I just want a basic rev limiter that runs off a shiftlight, hooked up to a relay that grounds the coil. And no, I dont want a bought one

the schematic is on that page

Lloyd has made a few of them, might even have one spare.

remember that relays are slow, thus the limiter is going to be interesting to say the least, not missing every other injection pulse / ignition pulse.

if the bee-r ones werent so damn pricey id get one of those. Anyone got a shift light tach they want to swap for a near new blitz F.A.T.T turbo timer?

[Mr Revhead]

why do you need one?

launch control

[chrisarmo86]

launch control is right, plus i have a tendency to be a bit heavy footed, want to keep 500rpm from redline

cheers dunny, but they are a tad pricey dont you reckon? the bee-r ones go for less than that on trade me

Where are you launching your car?

u cant get a 3sge curren to launch correctly? my curren was powerd by a 3sgte and with the right setup u can get it off the line fine.

[chrisarmo86]

it doesnt launch too well uphill, which is the only place i really give it the beans. BTW i use the car for hillclimbs.

Also i thing the anti-lag style backfires are awesome, sorry...long time group b rally fan

Jaycar used to make a kit, I tried to make it but had no idea what I was doing and it didn't work, was doing it in hopes of using it as launch control too.

[gasman]

i used the frequency switch kit and it worked fine

Just wire it up simple as, shift light output to trip a relay to cut power to the coil. The ones I used were with $30 tachos and worked really well. Limit very cleanly when in neutral and cut in quite soft up in the revs. Plus there is the added factor of them being adjustable whenever you wanted to

Good thing with the tachos I used were that you could fit a relay inside the unit itself, still have the shift light work and still have it as a 4 wire unit. Just ground one wire to the body and have a single run of 3 core wire to the coil. Made for a clean install too as the only wiring you'd see would be one run to the top of the coil

[chrisarmo86]

which tach's are you refering to Lloyd? What are the chances of getting you to make me one up ?

[Burning Angel]

they were trisco tachs that Repco had on clearance about 3 years ago. they dont do them anymore

What about a gizzmo shiftlight and launch control interface
