Guys,
The car in the Signature is running the P730SD setup. Wheneve i start it up from begin dead cold it bounces from the "correct" spark amounts up to 90d of spark and then back and forth for some reason, until it gets warmed up?
Am i running too lean or something along those lines?

Brendan

PS. I can send a diacom run to illistrate what i'm speaking of.

Anybody have any ideas?

That's retarted timing or below 6 degrees base. Diacom displays it as a high number. For instance: If talking about timing from the reference at 6 degrees, if the timing is 5 degrees it will display a 90. 4 degrees would be 89 etc

Any idea as to why it would be doing that? Thats bad isn't it? It does it during a cold startup and then levels out after a minute of running.
