gtir350 added a topic in Link G2 G3MSD DIS 4 SR20DET Direct spark misfireHi All, hope someone is able to help me out.
The project is a Nissan GTiR, Link LEM 3G. I wanted to switch to direct spark so got the following
cbr 600 coil-on plugs
Plug that fit into the above
MSD DIS 4
The car runs find under light load.
The problem I am having is a misfire under load. What I have found is that the larger the dwell number the worse the misfire.
I read that dwell had no effect when running CDI ?
When running 0.5ms I get a small missfire over 5000RPM over 14PSI
The more I turn up the dwell upto 4ms the sooner ( Less load ) the misfire happens
The Spark time is 1ms
Anyone any any advise ?
