I still have a few problems to work on however. The tach signal is not getting to my dash, neither is engine temp.
Also, cycle to get decent afr's seems really high. I only drove it for a mile or two but I am sure I saw over 80% duty cycle at ~3 to 4000 rpm and normal air-fuel ratio. I will do some more driving tomorrow and take some logs then.
you sure it's 80? I'm pretty sure the NV uses the same crank angle as the M20 (84). 14 teeth to the VR sensor at 6 degrees = 84 degrees.
as far as the coolant temp, that's driven by a seperate sensor unrelated to MS. it might not be hooked up. For the tach all you need is an output from the MS CPU (I use JS11) straight to the tach. the E30 cluster works fine with a logic level signal.
