New Procom arrived, installed, set to "0" per instructions and part number of old unit...Nothing...bike would not fire..selected to "1", still nothing, "2" and "3", still nothing...Selected to position "4" and she fired and purred nicely. Up highway 120 out of Dallas after warm up, and WOW! What a difference! ZERO popping on decel, and nice strong pull to 80 mph....All the way down the connector through downtown to the airport, she sings like a bird! Very happy with this unit, and the price!
