plus 3 golfer Posted March 2, 2015 Report Share Posted March 2, 2015 On January 7, 2015 I had the 14E02 update done which required reprogramming the Power Control Module (PCM). Since that time my last 3 tanks of fuel (over 1500 miles) showed an increase in FE of over 2 mpg / over 5%. In addition, the difference between the fill up FE and the displayed FE has narrowed. For example, on the last tank I filled up at 514 miles and 11.30 gallons of fuel for a calculated average of 45.5 mpg. The display showed 45.7 mpg. I would have expected around 43 mpg actual with a displayed of around 44 mpg. I'm also noticing that on typical normal trips, the displayed FE has been around 5% above what I would have expected based on previous experience. I will continue to monitor and compare FE as we get into the summer period. IMO, something has changed and it isn't driving style. Has anyone else noticed a FE improvement after any recent PCM update (not just due to 14E02). I would not be surprised if Ford has tweaked the PCM software further enhancing FE. The PCM module info from FORscan is below. I assume the "strategy" (likely last two letters) is an indication of the revision level. Could others check what their strategy shows.

plus 3 golfer Posted March 3, 2015 Author Report Share Posted March 3, 2015 For those that don't know the reason for the recall it is: REASON FOR THIS EMISSION RECALLIn some of the affected vehicles, the On-board Diagnostic (OBD-II) system may be inhibited when Diagnostic Trouble Code (DTC) P24BC is set by the Powertrain Control Module (PCM). When DTC P24BC is set, the Malfunction Indicator Lamp (MIL) will not illuminate to alert the driver of a potential impact to vehicle emission control systems.

SnowStorm Posted March 3, 2015 Report Share Posted March 3, 2015 There are lots of differences although some are the same but I have no PAM at all! :cry: All have the Part number: and Strategy: lines, 6 also have Calibration. Sometimes a lot of digits are different, sometimes just the last two letters. I see your Min.delay is 113ms (Bad) where mine is 32ms (Good). :) Maybe some of your data is getting lost. You would think all modules would have a part number but what do I know. Wish we knew the meaning of the numbers and/or parts thereof.

This may be why on occasion I would have gaps in the recorded data when using Dash Command. Maybe the Forscan forum has something on the meaning of the numbers.

hybridbear Posted March 9, 2015 Report Share Posted March 9, 2015 Any PCM update like this recall wipes out the KAM (Keep Alive Memory). This means that all values in the learned tables are reset to default. It could be that your car had learned values previously that led to decreased fuel economy. Many FFH owners with poor fuel economy have found that their MPGs have improved after they have cleared the KAM through the hard reset procedure.

Many FFH owners with poor fuel economy have found that their MPGs have improved after they have cleared the KAM through the hard reset procedure.True but this would presume that a) the learned values prior to reset were wrong and never updated with continual driving or b) the after reset learned values wouldn't over a tank return to the learned values prior to the reset. This simply makes no sense as driving style / conditions haven't changed and resetting the KAM should only result in a temporary change in FE as the values would be relearned quickly. So, IMO resetting KAM might change FE temporarily but not permanently. Most of the learned values I know of that might affect FE relate to timing and fuel trim. IMO, something has to be wrong with the hardware or software especially relating to emissions / fuel monitoring system, such that the learned values or other triggers would lead to a decrease in FE. The recall indicates that something might be amiss with the OBDII system monitoring with no MIL indication of an emission issue. This certainly could affect FE in affected vehicles. I doubt Ford would ever admit that this issue might have resulted in a loss in FE. :) Quote Link to comment Share on other sites More sharing options...
