Congratulations! I did my 27th anniversary in January.

The injector duty cycle is fixed in this ADX, the XDF hack/patch has always been correct.

Me too I still don't understand why the motor needs so much timing in it. Dave told me he did one similar to mine for another guy and he had to add 12 degrees of base timing with distributor.
Hmmmm...??? Man that's a lot of timing? I can see needed much more at idle if cam is causing a low vacuum...
