Have been informed that CJS in Bristol are able to bypass the immo in the 848/1098/1198 dash. There is no need for a chipped key but the immo light is illuminated all the time. Ideal for those of you with Race/Track bikes who aren't bothered about the immo light and want to use a second hand dash. Means the IAW5AM ECU can be retained. Maybe Chris @CJS can confirm and give a price.
Would appear this is done via the ECU so that it does not require the Wake Up Signal from the dash. CJS charge £250 to do the flash.
