phi135 Posted September 1, 2015 Share Posted September 1, 2015 I have an '81 280zx turbo. I'm using the MS3/3.57 - with the latest firmware. I've been driving the car for over a year - after many months of learning how to convert to MS3. Car had been running SWEET. I took it out for a Sunday drive two weeks ago - coincidentlally I went with a laptop connected, simply logging. I wanted to come back later and analize the log for any possible tweeks. Alas - damn car died when I was doing about 50. I pulled over, into a side street. Long story short - spent several hours doing some debuging. I have determined that I am not getting any spark. The MS3 is alive - I can put it on a JimStim - or in the car - the sensors appear to work, and I am getting RPM signal. Again - just no spark. I replaced the new coil with yet anothe new coil - same result. I also used the Tunerstudio output test mode to test spark. No spark. Any suggestions from anyone? I am attaching the log file I was recording when the car died. I don't see anything odd. My car config: - stock - everything except the MS3/3.57 - I am using the DIYAutotune trigger wheel Quote Link to comment Share on other sites More sharing options...
loy Posted September 1, 2015 Share Posted September 1, 2015 Do you see the ignition output on the jimstim? If not then it is possible something wrong with the ignition driver circuit. Quote Link to comment Share on other sites More sharing options...

Metro Posted September 1, 2015 Share Posted September 1, 2015 Sounds like your (stock nissan?) ignitor died. Quote Link to comment Share on other sites More sharing options...
phi135 Posted September 2, 2015 Author Share Posted September 2, 2015 The ig LED on the MEGASTIM is always on. On when I attach it to the MS3 - stays on even after I try an output test mode. I did replace the BIP373 just for grins. I read where some folks believe they have "blown" this component - still others insist that doing so is almost impossible.
