Hi,

For us to be able to provide that information you will need to provide the manufacturer name and part number of the injectors and coils as this is how we catalogue this information.

Hi,

See the attached calibrations.

The only match that I have for the injector part number is for a FAST brand injector.

Just use the voltage axis, for your fuel pressure setting.
