The formula used is X/500 = charging time in ms.Īnd just as important, this validated the assumed battery legend table at 0x4D056. That's the one which governs the time the ignition coils are charged dependent on the battery voltage. One of the results of todays work was the identication of the ignition dwell table.

The Fuel Phase table is mostly revealed, some details need to be validated, that's for the coming days. Time invested in the ongoing quest paid off. The next days will be to cold enjoy staying in the workshop.īut, it must be an ill wind which brings no good. I'm glad I used the better weather during the last couple of days to service my motorcycle pool and especially the Norge and Futura, which are new, and tailor-suit them to my requirements. It's been a cold day with lots of new snow.

So the working hypothesis now is that Fuel Value (Duration of injection pulse) + Fuel Phase Value (timing for end of injection pulse) determine the injection event in regards to duration and timing. Low values moved injection pulse end towards TDC, large values moved the pulse end to earlier timing. And lo and behold, a structure became visible. Then all relevant TPS settings were selected and the time delta between the respective flanks of the injection and ignition pulse were measured.

Then the Fuel Phase table was filled with staggered values suitable for identifying steps and uploaded to the ECU. ) to 0, then the pulse would be fixed in a relationship to TDC, regardless of changes to rpm or TPS. Set ignition values and all relevant trim tables (temperatures, baro, idle mode. Then the idea was born to do this in a roundabout way. The obvious choice was the 2 teeth hole in the engine speed signal, but I haven't found out how I could get my scope, a Rigol DS1054Z, to trigger to the lag. It looked strange.įor the longest time I tried to figure out a way to trigger the scope to a fixed reference. Rather large and sudden value changes and no obvious relation between value changes and legend values. Now the question was, which function could this be describing.

The Fuel Phase table is one of the bigger arrays in the 5AM, using 20x32 cells and having TPS and rpm as legend. And as a plus the battery voltage legend. Firstly the infamous Fuel Phase table (I'd give my left arm to learn who selected this name based on which thinking) and secondly the Ignition Dwell table. A good opportunity to follow up some thoughts.
