............. They don't look like degrees of advance.
Are there only 8 rows in the spark map or is that just half the map?
Thanks for helping us understand.
Yes after all decoding and after calculating in real degrees the final table it is not a similar figure as the hex code values.
Yes 8 rows in the spark map is all the map.
Note that i show you only the preparation of the theoretical calculation of the map.
There is practical verification in which the results are shown immediately.
I use my hardware tools as you use yours, so finally calculated the actual timing advance, AFR and limit potential engine performance.
My tolls are, a external knock sensor (for pings) and a external wideband oxygen sensor (for AFR). These tools are not "computers" or "windows screens", but these are standalone hardware that measure the engine operation completely independently and individually. As used a simple thermometer for measuring the temperature.
By these tools, i see live the real AFR and i hear (live) the pings, i don't care what kind of values are in maps of bin file (hex, dec or real degrees), the conversion into actual degrees is just the theoretical knowledge, for not to constantly repeat the same practice procedure..
So calculated and appreciating differences in values in the table and the differences in actual operation in the engine by great precision.
So practical, at each maps i gives more and more additional until engine have pings, so i know what this is the limit and faster timing advance that needed the engine at each revs of rpm.
Also i gives more additional at injection maps, until see the correct AFR (14,2-12,5:1 from iddle speed to red line) at my external wideband sensor.
I have no restrictions (european emission standards etc.), I have no MARKETING for different mapping from model to model, a parameter only is the octane of gasoline that uses the engine and the harware modification of bike (if have) - ι expect only the perfect thermodynamic engine operation. After all modification at maps, the engine running as best he can afford:
Correct AFR at all revs of rpm and the faster limit timing advance (by no pings) depending of using octane petrols (89,.95,98 ron) depending and variable to all revs of rpm.
With this whole process of amending the maps achieve maximum utilization of thermodynamic combustion engine, so yields more torque and power with less fuel used.
That see at dyno results, that's work called "tuning" :
