i just installed the megajolt in to my sunbeam alpine. the one problem i encounter t was with the supplied cable , the one i ordered with the adapter. after a day of troubleshooting.i found out that the the cable is wrong.the wires in the rj11 plugs are mismatched

my suggestion is,you should sell the whole kit(incl. the usb-serial adapter) then when you test the unit,with the adapters and cables that you sending to me. that way you and me are certain that everything that i bought from you is working together.
because the first thing i was looking for faulty was the usb adapter,then my wiring.tripplecheckd in the very end i looked at your cable,to find it was ng.
now my next problem. the car is idling just fine, the timing light shows 8 degree advance. the computer shows 16.
why? what do i have to look at or change?
