Can you guys help me figure out why the ignition settings in my 03 with Rev ms3 basic are way different than my 2000, also with a Rev ms3 basic?

The ignition is set up rising edge on the nb1 and falling edge in the nb2. The tooth #1 angle (deg BTDC) is 0* in the nb1 ms and is 80* in the nb2 ms.

Most of the other differences are explainable, but this is really odd. The NB1 ran just fine on falling edge, and I think that is how the base map was delivered to me from Rev. The NB2 base map was already in the ecu, and after tuning makes 350/339 to the wheels fairly reliably.

 

Probably different board versions. They use different input circuits for the crank/cam, hence the need for the rising on one and falling on the other. Both however should require 3-6* of tooth #1 angle.

 

thanks for the replu. Did you get my email about the base map for this ecu?

 

Replied.

 

Fantastic! Thanks!
