So you are using the VEMS disc? and not the AEM one?

I switched back to the factory disc when I went to AEM.

I thought I might give the VEMS disc a try but after comparing the two I've decided to not even deal with that and get the AEM disc.

The new AEM CAS disc came today. I'll probably give things a try tonight if it's not raining.
I really hope this fixes the problem.
Wish me luck.

Put the disc in, changed the settings, and I get stat sync (which means the ECU can read the trigger properly and rpm readings should be good, and ignition will fire). The car just sat there cranking though, with the occasional pop out of the exhaust. I'm pretty sure the problem is in the timing compensation setting. After messing with it for a while the battery started to die (it's getting to the point where I need a new red top). I put in a setting that I thought might work and with the last juice the battery had it fired and almost ran.

I'm charging the battery now and expect results soon. Then I can time the engine again, and get back in business.
It would have helped to have the GF around to crank the car while I watch the timing light, but oh well.

The GF came back and I used her car to keep the Sentra juiced. After running through all possible timing settings 24-0 in 0.08 increments things started to happen around 8.66. The thing started and I timed that bitch and took it out for a test drive.

It works! That means I'm free of random brain-bending ECU madness for ever! Free at last, free at last! Thank God Almighty, I'm free at last!

I just asked for pricing on aem pencils with a trufire ignition, if I can sell parts to get it, I am going to go that route and get the disc to go with.
