280zxcoastie Posted January 3, 2007 Share Posted January 3, 2007 I know it is a totally different vehicle, but, I had the same thing hsppen to me in my honda. It turns out that I did not properly set my timing. I fixed this problem by reseting timing for the third time and it solved my problem. Also, my ICM has seen better days I'm sure. Hope this helps.

big-phil Posted January 4, 2007 Author Share Posted January 4, 2007 ok I now read that I have to set my dwell, I'm going to try Mobys setting of 6, 2.5, and 1.5. I did'nt even know what dwell was? I hope I did'nt burn up the vb921. Quote Link to comment Share on other sites More sharing options...
trwebb26 Posted January 4, 2007 Share Posted January 4, 2007 Sounds too me that your input from the optical dizzy is wired wrong in the megasquirt. Read this thread and my troubles: http://forums.hybridz.org/showthread.php?t=115390&page=2 Read this http://www.msextra.com/manuals/MS_Extra_Ignition_Hardware_Manual.htm#hall and verify that your megasquirt board is wired for a "high to low" input signal from the optical dizzy.

big-phil Posted January 4, 2007 Author Share Posted January 4, 2007 is that for a hall sensor only? Quote Link to comment Share on other sites More sharing options...
