Your engine management system sounds the the same as the European 112hp "DJ" wasserboxer, which I always found ran better than the "MV" system we have here. They ran these with 10.5:1 cr pistons and I think 12 BTDC timing, but required the use of premium fuel to do this. I ran mine, for the little bit of time they were in there before swapping to TDI, at 3 BTDC and regular fuel and never had a problem.

I think I averaged about 12 to 13L per 100km at 100km/h when driving these.
