Hi Ben,

I wasn't bad mouthing. I simply asked why you are charging that much. I have purchased over $10,000 worth of products for different projects from DIY and will continue to do so, so I think I do pay my fare share to play in that sandbox, thank you! A simple the price difference is due to the gold vs. tin would have suffice instead of showing teeth buddy! Just relax...

@Skou
Instead of buying a MS3-Pro you'd better have bought a MS3-Pro module with one of my plug and play boards and mount it inside the stock case.
No messing with wiring looms, a connector in yet another box and much cheaper. Too bad I'm all out

@Hector
Just curious, what's with your extra outputs that doesn't work with my board? I designed the board to have all free pins connected to pads so you just need to add a jumper for an extra output.
If I ever decide to make a new board, any input you have is more than welcome.

You had me excited, but then you turned out to be just a tease!

I was actually considering the MS3-Pro module, but went with the standalone with harness as this was originally going to go into my very slowly progressing Lotus 7 replica. I should have just bought a Westfield.

EDIT: I want to buy an alternator pcb.

Compare log files beween software and hardware control and I bet you switch back to hardware.

Frank, it was my impression from looking at your board it would not have worked. I may be wrong though. I also am building up the pro module to mimic my current DIYPNP as far as connections go for a quick swap and so I could keep the DIYPNP as a spare. Oh, and this is a VVT engine in an NA.

I am using the stock coil trigger wires on the factory harness to feed ground directly to the BIP373's inside the case. There were terrible noise issues when I was sharing the ground from the ecu and running it this way cured it.

Also, I am using the one of the evap emissions wires for VVT control. The MAF sensor signal wires for crank sensor signal, while the cam sensor runs through the CAS.

Am I wrong?

Show me.

I can't make my software control mess up. I greatly prefer it over any hardware implementation I've tried, including the circuit that you copied. The only thing I've seen is Scott's example where there was a brief spike after a sync loss. That is in the firmware developer's queue.

With that setup it wouldn't have been plug and play, that's correct. There would have been some modifications needed directly on the board.
But I'll keep it in mind for the V3 version
