what would be the best clutch switch to use?

any ebay one?


also one thing im thinking about is if i set the launch control to 3500rpm when i change gear will it cut the revs to 3500rpm?

Launch control works by momentarily setting a rev limit - you can control that via a push switch of some sort.

Once you release the switch the rev limit is removed and you can use the full rev range.

(im basing that on when I used to have LC on Omex)

You could put a momentary push switch under the clutch pedal on one of these http://www.ebay.co.u...=item27ca4057a3 and set it to, say, 4000 RPM so that when the clutch is down, it is turned on and limiting. Then when you raise the clutch, the limiter will be turned off and allow you to rev it right up. 

 

You could even have another limiter set at around 6-8k RPM (depending on engine spec), so that you can do full throttle gear changes.

 

Any heavy duty momentary push switch should be OK.

Yeah I knew all that.....
That's why I didn't ask about any of that :L

I was asking what happens when are booting it and down shifting would the momentary time when you press the clutch the rev limit is gonna be like 3500rpm..... Wouldn't that be a problem?

Hmmmm, I'm thinking the spark would just be cut so you may get a little back fire when it sparks the fuel in the chambers...?

I'm intrigued now!

Just don't want to be causing any damage :L

The limiter just cuts off the ignition, so you'll probably just get a backfire, as above.

 

You could always have a master switch (like a toggle switch) on your steering wheel or something that you switch off when you've launched, so that just the top end limiter is active.

Megajolt do their limiter via a chunky resistor so it doesn't spark out of sync, the soft limiter is even safer as it just retards the ignition. I don't think it'd be too much of an issue on a gear change when you're trying hard - as long as the clutch is disengaged there'll be plenty of inertia in the flywheel. It'd do a similar job to a rev limiter.

I have a no diz, I'll ask they guy what he thinks

[coopdog]

Heres what it says in the users manual

The NODIZ ProTM features user programmable launch control. It effectively allows you to hold the engines RPM lower (similar to a hard cut) on pressing a button, which in most cases, would be a clutch switch. This in effect ensures perfect launching RPM, or you can employ no-lift-shifting where by you can keep the throttle wide open through gear changes and the engine will automatically hold back when depressing the clutch.

Does that suggest it's using the hard cut circuitry?

No idea :L

I believe so.

Just musing if it could be done with a soft limiter, or if there'd be any point.

 

Would you fair better switching it off first gear - surely there'd be a fairly consistent rpm point where the torque would get the better of your tyres. You could rig an override switch as an enhancement.

You could mount an ON - (ON) switch at the bottom of your gear stick so when your were in first it limited it to say 3.5k via one limiter and when not first say 6k for full throttle gear changes, then you could just replace your right leg with a brick and once the engines started just leave it on the pedal
