can i use the tilt switch on my car will this cause me any problems? my engine is a k82008 model gsxr 1000 my car is a chris gibbs locost!

Shouldn't cause a problem unless you roll your car in which case it's probably the least of your problems. Though personally I'd bin it cos you don't need it.

Although you could keep it as a anti-theft device e.g. mount it in under the dash in such a way as you can flip it upside down when you want to prevent some toe-rag nicking your car but then you flip it down when you want to go driving. Doubt the average car thief would work that one out

thanks! thats i good idea wouldent of thought of that one.

You can't keep it unless you mount in on gimbals!

A bike never sees lateral g-forces in use, only if layed on it's side. Mounted in a car the tilt sensor would see lateral g when cornering as a fallen bike.

thats what i was thinking have you had this problem or do you know somone who has had this problem?

I have one and its ok never gave me a bit of bother...
and its nice to know that it will cut the engine should we flip it....cutting power to that electric fuel pump

Dont agree, Mine is mounted arrow pointing up and has never given any problems.

Fair enough. I guess when a car corners at 1g the resultant acceleration is at 45* as gravity is also 1g downwards. When a bike has fallen it only has the 1g gravity acting at 90* to the bike, so as long as the tilt sensor is tuned to activate only if it sees significantly more than 45* it would be OK.

As I said above though, because bikes don't see lateral g during riding, I'm surprised the sensors aren't more sensitive.

Experience evidently beats theory in this case

Best answer is to tip a load of silicon sealant in the sensor (its easy to take apart) to ensure the pendulum never rotates to a point where it will shut off the engine.

Leaving it as is risks your engine cutting out, especially if you are hurtling around a track.

Don't just mount it vertical and think your done, we had this problem and on track you pull too much g and it cuts the engine: not safe.
Like progers said fill it full of sealant or in our case blu tack.

I think we tried just taking it out and shorting the 'up' wires but in our case this didn't work.

shorting out the wires wont work, it will need a voltage ladder creating with resistors.

if its anything like the zx10r sensor (a disc with a cutout that by the pcb in the upright position) then just remove the disk, i did this on the zx10r so its just the pcb and it still runs fine, nothing to go wrong then.




its also a weight saving..........

thanks lads!

I still have mine... but i filled it with RTV so it cant move


chunky2772 - 11/9/10 at 10:23 AM

well! took tilt switch apart last night stuck it in possition with some two part glue hope this works (fingers crossed)
