Ignitech on an EFI bike - ignition only

Would be good to know f sure if TPS is linear or not:

All the 1000 maps are based on a linear TPS.

from a very quick check, its linear....

Now we`re looking forward to the wiring layout, must be challenging f sure....

I managed to get a Ducati Performance map and popped the advance data into Excel, along with the data from the Ignitech file.  here is is in graph form.  the Ducati map has 32 points on the RPM scale that are mapped, and the ignitech 10, which I feel is plenty.  A lot of early electronic ignition bikes had two...  tick over, and full advance!  my old Jota jumped from 10 degrees at tick over, to 34 degrees at 2000 RPM!

there is an alarming blip in the Ignitech graph which may need some investigation when its on the road.  the Ducati map is what I am used to seeing on other cars I have played with.

It will be easy enough to replicate the Ducati figures into the Ignitech map though...  my mate showed me how to interpolate to match the different scales...  but I glazed over after 15 mins!!!

1. Second table is your converted map? Looks a bit odd , f e 30 dgrees at 2500 RPM way too much.
Those dips shouldn`t be there.
2. Your DP map, is it a DS map?

Be wary of excessive advance with twin plug heads.

I managed to get the raw data from some Ducati ECU files.  I have colour coded it to see the pattern of the values in a visual format (isn't Excel brilliant!)  Across the top is the RPM, and down the left is the TPS values,  The lower values are throttle closed.  these follow what I would expect to see on a 3D advance map.  I hope to replicate these in the ignitech map on the bike.  Just need some decent weather to ride it!
