Okay, hooked up the stock ignition and probed the EST line while car was running shows .239V at idle so it looks like things are okay from that perspective. Still as soon as I apply 5V to the bypass when running on the MSII the engine stalls. So this has to be my ignition settings. Back to the ...

This seems to get more complicated.

I started the car running on just the ignition module and leaving the MS EST line and bypass unplugged. When I measure the voltage on the EST line it is 3.39V. Now I plug the EST line into the DIS module and the voltage drops to less than 1V. I really have no ...

Figured it out

My cable from the MSII to the relay board is kinda missing a wire on pin 36 Moved everything over to pin 25 and now everything is cool. Except the car won't start and run which is how I know I'm controlling the timing. Off to the megamanual I go.

Update: Sorry helps if you measure the right pin its actually 2.19V.

Hooked up my ignition on the weekend, but it seems I'm really not in control. I confirmed 5V is reaching the ignition module via the bypass, but adjusting the timing made no difference. I slapped the MS on the stim and measure the voltage output on the EST line and it is only 0.85V. That really ...

Must have been a bad ground or vref. I cleaned up my wiring and reran wires for the tps and clt. Signals are now clean as a whistle. Also ran a ground from pin 19 of JP1 on the relay board to the engine ground.

Well traced the wires back and they look good now grounding that I can find. Coolant level is good but still getting noise....only in the downward direction. Thats an increase in resistance right?

I've got a new sensor so I'll replace it in the next couple days and see if that does the trick.

Thanks guys, I look into both those today....don't really want to pull the sensor if its still good as I'd have to drain most of the coolant.

Just pulled a log from my MS2 V2.2 and noticed wierd drops in my coolant temp reading (like inverted spikes, briefly dropping 10-15degrees creating what looks like big noise in the log). It appears to correspond to with acceleration or decel. Fine at idle and for the most port during cruise. Is this ...
