Are we being thick here ?
I've not been able to try this cos my road monster didnt come with a code-card ...
(it _was_ cheap ! any suggestions on the easy way to get the code ?)

BUT, if the immobiliser is disabled, will it stop looking for the correct key ?

AND ... I cant find any instructions on how to re-enable the immobiliser if you do disable it ?

Phil,

I haven't tried it nor am I going to but, I doubt that it will work tbh. To try this you would need to have the ignition on. Only a fool unplugs/plugs in live electronic components - you would run the risk of trashing the panel electronics and/or the ECU.

Suggestion: If anybody does try removing either their cpu or the instrument panel then be sure to remove the 3A fuses in the fusebox first to isolate them.

I don't think we're being any thicker than normal Phil !

The immobilliser can be disabled using software, but the software needs the code to be entered from the card wot you don't have. And yes, the ecu will stop looking for the key and clocks.
Re-enable it using the same software.

Have you found another way to immobilise it??

Added:
twpd is obviously spot on... don't be trying to mess with circuitry while it's live!

yeh yeh yeh - you young whipper snappers got the wrong end of the stick !
what I mean is ... if we can disable the immobiliser in the clock circuitry - why isnt that good enough ?
Wouldnt a disabled clock-unit work with any key ?
I _am_ assuming it stays disabled of course - or is that what you mean by 'using the software' - which really means using the dealers diagnostic computer ?

(I am an electronics eng who writes embedded software for a living :saint:)

Ok phil, i gotcha!

i gather the immobiliser is in the ecu and is looking for a signal from the clocks before it wakes up... so i can't see that disabling the source signal would fool the ecu otherwise they'd be easy to just hotwire wouldn't they?

(I'm not an electronics engineer and I don't write embedded software for a living!)

but but but but ....
the keys are coded to the clocks ... ?
the antenna is wired into the clocks ... ?
...
a blank new set of clocks works with any ecu !

you see where my thinking got me now :puzzled:

nobody said they were impossible to hotwire :devil:

The simple and effective solution that is proven to work is to fit an FIM ECU. The best engineering solution is always the simplest. ;)

Thats how I understand it, don't suppose anybody knows what signal this is, as I understand it the ECU is also coded to the key system which would point to the signal from the clocks being a unique signal for each bike rather than a uniform stream of pulses that could be replicated by a signal generator.

had a long chat with magnetti merrelli about this today,if your bike has never been run with the red key your clocks are uncoded ,if it has you will need a blank set of clocks to run it.
As long as you dont use the red key the replacement clocks will remain uncoded,therefore my earlier suggestion satnds.

I'm getting too confused! Think I'll just plug in the laptop and hit the override button!!

So butch, are you saying that the system will demobilise without getting a signal from the clocks?

twpd - sadly, my budget is saying no to a FIM ecu :sniff:
