I also changed my locked ECU for an unlocked S&S G56 supplied one and have 569 cams, roller rockers and G56 exhaust (one of the first they produced). All was good until the unlocked ECU failed totally one day. I finally got a part payment from S&S for a replacement but this is the later type (with the different port) and it came with a KH basic Stage 2 map, G56 couldn't supply S&S ECU's then.
As there appears to be no one with any Protune 2 experience and a M3W compatible dyno in the UK now I am stuck with that. Hopefully Red Leaders map will be a bit better??? The early S&S ECU maps are not compatible with the later ECU's by the way. If you have the later ECU possibly you could email me a copy of your map Wilson?
