Leading Ignition Firing at 180 Degrees
Hey guys,
Just wondering if anyone else has seen this. I have an E6X installed in my 87TII (stock ignition), and when checking the timing for the leading ignitor, when I hook up the timing light, sometimes it will show that the coil is firing 180 degrees off. All I have to do is open up the timing light clamp and close it again, and it goes back to flashing on the proper timing mark. All along, the car is running perfectly smooth. This occurs on both L1 and L2.
I have seen this occur with two different timing lights, so I don't think it is a timing light problem. I also have the reluctor gain set to 0 for both the home and trigger, and a falling edge for both as well.
Anyone else seen this or have any ideas?
Thanks,
Greg

Whoops, just reread your post a little closer... So, if the coil fires twice per eccentric shaft rotation, that would mean it would fire 6 times per rotor rotation?
Thanks,

If the ignition system is totally stock, it tends to miss about every 4th spark.
Then, on top of everything else, most inductive timing lights don't pick up every spark event.
