Fuel Command Center Version 1 Modification

Back from my trip (without the car) and ready to tackle the modification as recommended by the FiTech support kids.  While on the trip had conversations with several friends about the modification and they all agreed it should make a difference in the temperatures inside the unit.  Plan to run the return line over to the mechanical pump and tee into the return line coming off of it.

Which parameters in the system do I need to make modifications to?  Please use the list from the Handheld Definitions so I know exactly which ones you are referencing.

Thanks.

Doing the FCC mod does not require any changes to the settings.  Just make sure you have the fuel pump PWM set to the Fitech recommended value.

Thanks.  I won't be able to work on the system until next week.  Hoping this will do the trick.

Finally have been able to spend some time in the garage and complete the modification to the FCC.  Test running it at idle I notice that the input fuel pressure hovers between 1 and 3 lbs, before it was between 3 and 4 lbs.  Wondering if I should have capped the return line feed out of the mechanical pump instead of teeing it with the return from the FCC.

Thoughts?
