Timing Keeps Spiking

[Assmatic]

After installing the MS-II, the car has had problems with the timing spiking, thus causing it to be un-able to be tuned

Is there anything you guys might think could be causing this? I'm going to go back and re-solder the connections and maybe add shielded wire in a couple places like the TPS, but before i do, has anyone else had this same problem and fixed it? or might anyone know what is causing it?

With accompanied tach spikes? Reroute the crank sensor wiring away from that of the ignition system and other high power leads.

Off the top of my head, be sure that your grounds are isolated and the ECU box is not grounding out.

Hmm well, the crank wiring im going to re-do with shielded wiring, but it's away from any high output except the alternator? which I can't help because the two are so close.

The grounding i have all the sensors grounded to one spot, and the ignition grounded to a seperate spot, i mite re-do the grounding connections a bit and try make them a little better though. Maybe that might work
