never had to think about it, till now which knock control system have the cossies? heard about various versions. will it adjust the ignition timing only from "standard" to "late" and max. back to "standard" only or from "standard" to "late" and if necessary "earlier" than "standard", too? is it also useful to go for (re)mapping after filling the car up with 100/102 octane or is it useless? hope it makes sense!?

cheers
