I'm not sure about this, but it might fall in line with a certain bike built way back in the 1980's. This bike had a 3 stage ignition curve. If the bike lost a wire or a vacuum off the sensor, it would default to 2 ignition curves only. And as I'm trying to make it all work in the processing of it, it might be the same sort of 3 stage processing the motherboard parts are handcuffed to.
When you interfere with a wire on a computer type bike, it has this loop that if you do any of 3 things to it a conversion happens. The cause of the effect turns to a limp mode, a fail-safe mode, a backup mode occurs. They all mean the same thing is if a wire is out of a connector, a connector not connected, or a short to ground, meaning, signal out of range.
If a wire is tampered with in the gps for example, say a wire was out of the connector, the gear shift window locks to a 6. This indicates a code has been set. This also sets the sensor as an out of range or a digital input. There are no longer many [1-N-2-3-4-5-6] analog inputs. With the continuous signal now sending in nothing, the ECU detects a closed loop is compromised. This also has its loop to the ignition maps when shifting occurs. This wire was also hooked up and down the line and into that ECU or the motherboard.
There was an X and Y occurring. X was the analog, and Y was the crank speed. The ign maps were being Triggered thru shifts and rpm is held for so much Threshold as RAM saved. Then it is Discharged and is repeated over again is to where in the rpm to ign curve should the bike's map be in? The analog is lost, a fail-safe enters and the middle curve is sort of missing>> losing that analog input. You get this little snap of bottom end grunt, a crispy type twitch feel or responsiveness. How close am I?
If I open the book and see the abstract sort of reads in my kind of abstract: 'start' ~ 'fast idle' ~ 'rpm Threshold to full advance.' That means 3 ign curves. The middle is out. I can't start the bike that high an advance so the processor inside defaults to [I wish I knew] and now only 'start and full advance' are the limp/backup/fail-safe ign curves. The start rides up the rpm and then is Triggered off as the rpm Threshold reached another Trigger point and the process is repeated over and over again until the rpm drops back into that retard-start Threashold, i.e., timing retard eliminator... which should read as EFI (eliminate fast idle).
I just tried using another engish conversion program, but boolean took the day off. My luck.
