very awesome project! Glad to see it going.. wanted to ask why it wasn't possible to use the bmw coil's with mega squirt? Does the megasquirt put out a +12v signal, and the bmw coils are expecting the signal wire to be grounded, such that you'd need to build a signal inverter so to fire them? Is the stock ecu doing the tach, and vanos and nil else?
Nice indeed - btw where did you source that exhaust manifold? I've been looking for something to mount a small garette turbo I have , that manifold would be perfect!
