Kanjo` Posted May 26, 2020 Report Share Posted May 26, 2020 Currently I am not in front of my pc to see your log but it most likely be your aem epm . I have the same car and engine but I am using oem dizzy as my trigger . Took it apart removed the internal coil and just kept the triggers .

remski2 Posted May 26, 2020 Report Share Posted May 26, 2020 Looks like your dwell is dropping to 0.4 ms.. Quote Link to comment Share on other sites More sharing options...
GermanEj1vtec Posted May 27, 2020 Author Report Share Posted May 27, 2020 I know, but why? I am now trying an original distributor. Quote Link to comment Share on other sites More sharing options...
Adamw Posted May 27, 2020 Report Share Posted May 27, 2020 Dwell scatter is a common symptom of trigger error. It generally means the ecu is not receiving regularly spaced/timed "crank teeth". Those EPM's dont have a great reputation so im a little suspicious of it. Can you do a triggerscope just at idle and we'll see if anything looks unusual in it.

GermanEj1vtec Posted May 27, 2020 Author Report Share Posted May 27, 2020 Installed the original sensors and, errors gone. No more misfires or anything else. I'm leaving it like that now. However thank you for your help. Great forum. Quote Link to comment Share on other sites More sharing options...
Kanjo` Posted May 28, 2020 Report Share Posted May 28, 2020 Glad you sorted it out . Maybe you should look into the T1 trigger kit if you want to upgrade to something newer . The dizzy works well the only thing I also did was since it was apart and still the OEM dizzy the wires were exposed so I depinned the plug and used heat shrink on each wire so they do not touch each other .
