Yeah I can see the GM line of thinking on this, but I think the low table is still to high for our 91RON and the High is too High for 98RON. They almost needed to do a crude select all and drop 3 or 4 degrees on both tables. I say that because I've heard of audible knocking on Aussie Cruze's, now surely if it's at the point of audible knock the scaler has already biased to the low table 100% and has nowhere to go. In fact they tend to knock the worst at part mid throttle, not WOT.
Well, there's no plans for that on this Cruze, but I do agree that is the best solution, but to be honest, living in the speed camera capital of the world winding this thing up isn't going to happen too often.
