The addition of the Revo DSG map doesnt cause high timing pull,too much advance in the map is the problem here, or bad fuel maybe high intake temps?
When mapping any car I always try and get as close as possible to Zero timing pull by advancing timing bit by bit until you get an even 1-3 degrees of pull and then you know you are close to MBT (minimum best timing) and take out a little to be on the safe side, then the customer also has lots of headroom incase of high intake temps or needing to use a 95ron fuel, or both. A certain amount of mechanical sympathy is a good thing.
An engine pulling 8 on the timing wont make any more power than one pulling 1. When too much timing is pulled this can cause over retardation which in turn causes higher exhaust temps.
Looks like you might have another road trip Dom, and more data logging (go easy on the brakes
)
I still dont offer a stg2+ (other than Revo) for these very reasons, way too much work needs to go into them, far too much to expect a customer to be able to cope with understanding let alone expecting them to datalog and remedy the maps by trial and error by email. Superchips had the same issue with Bluefin, so they make the map stupidly safe with very little ignition advance and slightly rich fuelling (otherwise known as "vanilla flavoured mapping") there is a lot more that needs to go into a good stg2+ than a bit more boost, ignition timing and fuel
Did u get an overlay graph of the current stg2+ and our Stg2?
