Mfd Injector % And Map Tuning

[StretchGSK]

Hi

I have an F-CON V pro in piggy back mode setup to use MAP.

The AFM are still in situ. (not for any reason other than I have not got any delete pipes made up yet.)

I am also running in piggy back mode to allow me to retain the factory key immobilizer.

The problem is I now see incorrect/false injector duty cycle readings on my MFD.

For example I see 99%-100% where in reality the injectors are peaking at about 85% as shown in the F-CON Power Writer output while on the dyno.

I am pretty sure this incorrect reading is due to the fact that the factory ECU is still supplying info to the MFD and may have something to do with an erroneous signal from the AFM's?

What I would like to know is what can be done to make the MFD reading correct?

Can you send a signal from the F-CON to the MFD?

Surely I am not the first person to have this issue?

Thanks
