Nabors, quick question..That's pretty common unfortunately. Many users going to timing control have had the 59k issue. The tach reads 59000 rpm, and the ecu shuts down usually. But you can fire it right back up after a quick key on/off. And it's totally random.
The fix is different for most people.
1. make sure your Tach wire is away from all power and ignition wires. It's still live when using the timing control. At least according to Fitech.
2. make sure to isolate the black coil wire from all power and ignition wires.
3. make sure your 2 wire pickup wires are also away from all power and ignition wires. (seeing a theme here?)
4. If your rotor is out of phase too much, and you start getting a long travel or weak spark, it can cause excessive emi noise.
5. you can try a few ideas some have used. aluminum tape or copper tape on the pickup wires, to shield. Or using a shielded MSD pickup wire.
6. I personally had this issue on my chevy motor, and a ferrite choke on my pickup wires eliminated the issue.
7. ford engines with the dizzy in the front seem to have the most issues with this. We believe due to proximity to the ecu. some fixed by going small cap, replacing large. one user even did a quick test, and wrapped the dizzy and throttle body in foil and it fixed it. Another did aluminum tape wrapping on the dizzy cap which fixed it. It's just about blocking the emi noise.
8. Some are getting it if they run electric fans and when they kick in, they are introducing some type of feedback. I use electric fans and have no issues, but I also don't have fitech controlling my fans.
So there are some ideas.
Good luck, some have no issues from the start, and some gave up and went to an MSD 6530 CDI with timing control built in. But some trial and error testing will help. Check the suggestions above for testing.
It's usually completely random, and that's why it's tough to isolate.
But even though I'm not boosting, I really enjoy the timing control, and so does my motor. So now that I have used it, if I didn't' fix my 59k issue, I probably would have still went to an external timing control setup.
How can the system get a tach signal if the motor is not turning over? Just from some other electrical source?
