From what I read, the device monitors the signal from the sensors, it allows you to see the map, which is basically a spread sheet.

The map would have default values and then those would be affected by inputs from the various sensors. Your goal would be to access the default values and (+/-) those, where the problem occurs.

The problem with these or this device is it requires knowing what model bike it is on, my best guess would be that GX650 BMW single would be close, but you would need to inventory all the parts and compare them.

It is possible they are identical and only the default settings differ and also the variances, as changes based on sensor inputs. Those variance would be based on specification provided from Jialing to Bosch and I bet that they are not 100% accurate, in fact they are likely too flattering to the engine.

I do not think they override or overlay, they only allow access to the baseline settings.

As far as the cam sensor, they may have been optimistic on the play in that over time? It may be one variable that is part of the problem, but that is timing not related to the fuel injectors. Some systems do both others do not? Basically some are or have the CDI integrated and some do not.

The timing based on the position of the crank and with consideration of the cam, to much variance and it may not fire? Or may advance it or retard it. Is that what is called variable timing, kind of sort of like it maybe, it may also be affected by the other sensors.

As you ride the device offer a gauge, it tells you what the injectors are at when the problem occurs, then you go back to the table and see the defaults related to that (rpm or throttle position) and adjust the baseline for that scenario .
