Backup up your current map first and use with caution
In the map there is the following table to account for injector response to varying system voltage.
# This table relates to the injector open/close times as a function of voltage
# The value here is roughly the time ( in us )
# 16V 15V 14V 13V 12V 11V 10V 9V
InjVOn 1000 1000 1100 1200 1500 1700 2000 2500
The values were my guesses with no basis.
Now thanks to recent MyECU owner Tyrone Smith of Motorsport Electronics we have some real figures in the image below.
Fuel pressure is usually 3 bar.
The MyECU has a few extra entries that you can generate by interpolation.
If you use the values as is you may need to adjust all the InjDur entries to keep your map unchanged.
These values are added to the injector duration last after all the normal compensations for barometric.
The important thing are the differences in values rather than there absolute values so we can produce values that require no further changes to the map.
For instance lets assume your bike runs at 14V when rolling. The original value was 1100 and the new value would be 500, a difference of 600.
If you now add 600 to each value you will now have a table that provides proper compensation but requires no further map changes.
