just posted a new message and forgot a big question. in the new car craft they bought the 91 ta. they said they adjusted the timing to 12-15 from the initial of 6 degrees. since the computer adjusts the advance, how would i go about doing this. is just like normal( unplug the connector, etc.) or what. i believe i might experience spark knock but i dont know.

 

Yea, just unplug it an use a timing light. That seems really high though... really unnecessary to go that high, especially if you plan on starting the engine after its already hot.

 

UM, I am confused here.....

why would they move timing of the base 6 deg. if the ecm takes over after the motor starts?

 

The ECM adds timing based off the manualy pre-set base value.
