Bill,
Would the EBP cause MPG loss on all FICM strategies? Are there any other symptoms to look for to help diagnose it?

Since EBP affects the ECM specifically, there would ideally be a loss across any of the possible FICM strategies. However, some FICM strategies might experience more severe loss than others.

Keep in mind that the EBP sensor is just one aspect of a number of things that can affect mileage. It just happens to be something that we see quite frequently.

While poking around I found this (6.0 PowerStroke bulletins), which might explin things.

2003/04 Computer Programming Recall 06E17:
Truck built before 9-29-03 are being recalled to have the computer reprogrammed. The reason for this recall is to correct fuel injection timing during cold operation, EGR valve control, lack of power, check engine light illumination (P02263 or P0299), hard starting and rough running concerns related to Exhaust BackPressure sensor corrosion. Other symptoms not listed in this recall, but which could occur, would be excessive smoke, turbo control and surging at idle or cruise. The new update eliminates the EBP sensor input to the computer. The exhaust backpressure will now be inferred/calculated using other sensor signals. Trucks should be reprogrammed using versions 41.8 or 42.1 or higher.
After this reprogramming, the truck should be test driven, the computer checked for a codes and the codes cleared (even if none are present), the key cycled on for five seconds, then turned off twice, then the engine started and allowed to idle for 5 minutes at operating temperature to allow the computer to relearn the EGR valve closed position value. This is to prevent erronious codes or driveability sysmptoms related to the EGR valve an turbo performance. Broadcast Messages 5452, 5529.
You should notice an increase in turbo cycling closed/whistling at idle and at stops. This is normal, and is to help keep the variable vanes from sticking.


So Ford was having probmles with the EBP and decided to ignore it?

Since Ford couldn't do anything about the ROOT of the problem (the EGR system), they simply mask the symptoms and disregard the EBP sensor by using the inferred EBP strategies. It's no different than when they used inductive heating strategies in the FICM to "eliminate" the stiction problems with the injectors. Rather then fix the spool valve design, just heat the injectors up.

Found the valve, pull it along with the tube, pretty clean just some minor soot. Cleaned it up and re-installed. Doubt that I will see any differance

Here we are 5 months later, no increase in mileage. One thing I can say is that I can run my predator 100 hp rating and still pull 24k lb total weight with out running over 900 deg. egt. Nice to have the extra umpffffff on tap.
