Hi All,

Just polling for ideas as to which circuits to cut with the immobiliser on a 'Busa engined BEC. I have to fit it for IVA. The immobiliser I have will cut two circuits.

Fuel and ignition would be my guess, though i'm sure someone will come along that has actually done this and give you a mre accurate answer

Just did mine. I did the starter motor circuit & ignition (R1) but you could do the fuel pump instead of ignition.

fuel pump and coil on mine

i use to fit car alarms for a living. To be insurance approved for petrol it had to be two of the three. That is ignition, starter or fuel. I would not do quarter because its the easiest to bypass. Also you can hide fuel and ignition cuts better. Make sure the cuts are in different areas of the car and physically but about 300mm wire out so they cant just strip and twist the wires back together. Stay away from the ignition barrel.

There used to be a dislike of imobilising the ignition circuit, due to the increased risk of failure whilst driving, cutting the ignition is an immediate stop, at least with fuel the impact is more gradual and just about controllable.

I'm suprised IVA specifies Ignition, jus my opinion......

Are you using the standard clocks? What about making sure that you get clear error codes on the dash. For example the roll-over switch. I guess fuel pump is good because you can hear it not running (if you know what I mean).

I am just thinking of the next time the engine won't start. It would be good to know if it is the immobiliser before you flatten the battery. I have flattened my battery a few times now and it is a pain.

On fuel injected cars, cutting the power to the fuel pump is pretty much as abrupt as ignition. I agree if it is carbed though

I did starter and fuel on mine.

if you are fitting the Immobiliser to a genuine Suzuki Harness, then you can use the side standrelay as one of the cuts. this will interupt in the same way as if the bike was in gear with the side stand down. this is a good way to cut as it will bring the CHEC light on the dash (if you are using the Suzuki dash board. it will also Not bring on any FI light.
the second cut should be to the starter circuit. Neither of these will create FI faults and will comply with alarm instal requirements.
