Calibrated the GM IAT, set the timing to fixed, kept the TPS unplugged until I can figure out something else for it. Cranks but won't run, here's a log.

I'm a retard and plugging the MAP sensor vacuum line in helps a lot. It seems to be running insanely rich and won't idle though. And obviously I still can't connect the TPS.

Ok, I'm officially lost. I pulled the ECU and as far as I can tell it's wired correctly. TPS on the main board is jumped to 3F. That's the only relevant build instructions I see. It's a 96 with the variable TPS. I've tried two different TPS sensors to make sure the sensor is not the issue. I turned the key on with the TPS disconnected and then connected the TPS in an effort to calibrate it. The sensor data makes no sense, barely any spread and the WOT value is lower than the zero throttle value.



I've spent days googling around and I've found mountains of stuff about the 90-93 TPS and retrofitting but nothing about this. Any ideas as to what I need to do to make it work?

I was looking at it last night with the help of some people from the facebook miata group and I think that's the issue:

Am I correct in my assumption that 3i should be vref? If so, what should 3L go to if anything?

I apologize for my noobness but I thought I would be able to plug this in and learn the tuning software then later down the line build an MS3 or something after honing my soldering and electronics skills on other projects.

Anyone? It looks like VREF should be 3i, not 3L. Should 3L be anything?

VREF is 3I, 3L is not connected.

That fixed the TPS issue. I hooked everything up and went through the whole setup. I cranked it and it ran very poorly with A/F ratios in the 10's. I went through and checked everything again to make sure I didn't miss anything and that all was set up correctly according to their website. I just went to try to crank it again and now I get no injector pulsewidth. What the hell am I doing to make this ECU hate me so much?

Please post a data log of the no-pulsewidth issue.
