There are several readings related to fuel:
1. Adapt Factor 70.2% @ Idle / between 9% and 18% @ cruising
2. Adapt Fuel -600 us (this is the reading at all rpm's in my driveway
but this value starts changing after a few minuets of cruising). What is
"us"? (It's like a u).
3. Injector Pulse 3.3 ms @ idle and fluctuates from 2.1 to 2.6ms as the
rpm's flutuate from 1200 to 1600 rpm's (with a steady foot on the pedal).
