your ecu will be running closed loop most of the time ihtisham, using the primary lambda sensor feedback to calculate the injector durations.
which is why your qg injectors made little difference.
mark will have changed the open loop fuel tables, so it will probably overfuel when booted with bigger injectors
Right okay didn't know this. Do you have any suggestions for what I should do regarding injectors then?
1. Stick with the CR12 injectors that Mark recommended as that's what the ECU has been calibrated for.
2. Put the QG15's in anyway
