Here is the data from the road test with EGR valve disconnected.

Are there any Forscan gurus on this site?

I would like to be able to export the data logs in CSV format, but I don't see how to set that up in the program.  Alternatively, if anyone knows the format Forscan uses (.fsl?), I could probably write a Python script to convert the data.

Welcome to the forum @rgsheehan!

 

Interesting data collection.

 

It looks like you can save the data as a CSV file.

I have not used Forscan yet, but one thing I've found with mine is that the "tugging" only occurs on a damp, cool day, on a cold start. Once everything is up to operating temp, the condition quits. 

 

It was far worse before replacing the dpfe. I have not tried to replace the egr itself yet, but I may do that next.

Yeah, Biker, it was your posts that convinced me to try the new DPFE.  Wish that would have fixed it.  My Edge doesn't seem to care if it is cold or hot, it just always runs crappy under light accel.  I'm pretty doggone sure disconnecting the EGR valve made a difference.  I'll try that test again next chance I get.  That threw a code, of course, but I was able to reset it with Forscan.  Before I reset that DTC, but -after- I reconnected the EGR, I drove it around a little with the check engine light on.  The tugging was back, but maybe different?, not sure.  Does anybody know if the PCM changes it's behaviors just because the light is on, even when the condition causing the light has been corrected but not yet reset?

This car is so incredibly frustrating.  It is really nice, looks good, comfortable, gets way better mileage than my Nissan Frontier did, cruises down the highway like a dream, but does nothing but p*ss me off when driving around town.  And now also, there is the worry that the transmission or torque converter is going to fail.  Even in the miraculous case where it fails under warranty, I have little faith in the underpaid serfs at the Ford 'service' garage, you know, the ones telling me 'No codes, no problem'.

 

I'd really like to get away from all this over-tec-d emission controls rats nest, and 20 speed trans absurdities.  My next one will be all electric.  But until they get -that- stuff sorted out, I guess I'll just keep testing and tweaking.
