The stock tune has a LOT of ignition timing, but far too much and the engine will "ping" or "knock" (caused by too much ignition timing advance) bad for big-ends, pistons, engine temps
even when running on 98RON fuel
So the ECU sees this and will pull back timing from the whole ignition map until it stops pinging, (losing power and economy) and slowly add it back in to areas where the tune is good.
But in most cases the ECU can't put back in all the timing that was taken out. making teh car less efficient and not as smooth to drive
So just to clear that up even with 'headers' and a stock tune there still may or will be 'pinging issues'?, very interesting if so
So many different opinions out there
Just spoke to a guy today and he said the same 'headers & tune" is the way to go
What about DBW throttle mapping with the tune would that sort out the 'ping' or 'knock' issues?
Yeah I think DBW throttle mapping might be the way to go after all it is the family wagon, keen to get more out of it but also needs to be smooth.
