Installing my restrictor with a datatool alarm.
 

Hello,
I've had a look through previous threads to see if i can find an answer to this question. I had a Datatool S4-C1 Red Cat. 1 alarm on my Sv and i want to fit my restrictor. My question is if i disconnect the battery and remove the current ecu will the bike be immobilised when i start it back up again???
I dunno if i'm being over cautious :smt031

No, but if you don't put it into service mode first it'll whine like a bitch when you disconnect the battery.

You don't need to actually touch the battery to replace the ECU. I think the bike will be dead with no ECU in, so the circuit might be incomplete, but still might be giving juice to the alarm.

Dealer didnt disconnect my battery when he did my ECU and all was fine, dont worry about it.
