Hey Hersh,
I have been meaning to call and check up on you and Miss Paula but never remember when things are calm.
What injection do you have ... port or throttle body ? I think you have a MSD ignition? Most of the systems use the tach signal to trigger the injector pulses and bandwidth. MSD has a quirk or some systems care if you are using the yellow trigger or the white trigger. The MSD can be made to send a trigger signal by tapping the the wire just like you would check the MSD box for coil output voltage.
Another got ya can be = does tach signal continue while cranking the engine or not. You must have a ignition source that does not drop out while cranking the engine over. Hang a volt meter on ignition source wire and watch it when you crank the engine over. hope this helps............ call me if you get a chance. Jeff C
