On my 2j vr sensors with the Pro setup I had to use a 10k and shunt with a 1k as well, if I didn't it would spike rpm to 7000, stall the motor with 30* of timing then fireup, but since it snap shotted th map signal at the rpm/start spike, the initial baro reading was off and my tune was rich!!!

The 3 and 4 wire coil packs are the same, the 90 4 wire style has the "or" gate on the coils for the tachometer while the 3 wire setup has a tachometer output on the igniter itself
