inj Duty cycle + bigger injectors + logging

[aurace]

If bigger injectors are put into a 4g63 and then datalogged - will the duty cycle on the logger still be accurate?

i.e. how is the duty cycle calculated? is it calculated using a fixed flow value in the ecu (eg 450cc)

thanks

if you put bigger injectors in and compensate for them with a SAFC or a chip, then yes ur duty cycle will go down. Otherwise ur inj duty will stay the same, and u will be getting more fuel everywhere.

The stock ECU can auto adjust to a point, but not enough to compensate for larger injectors.
