Trent, when running nistune how are you adjusting the tables to get the correct dwell.
As you would know it's not as straight forward as different ecu's.
I found I had to modify both tables to get it acceptable, but even then the ecu does some weird stuff with the dwell (reducing it) on a series 2 stagea. Matt seems to think only the voltage correction table needs adjusting.
I appreciate your time sharing what you have found so far.
