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. https://www.ford-trucks.com/forums/attachment.php?attachmentid=269143&d=1600129597 Edited June 3 by Wubster100 Quote Link to comment Share on other sites More sharing options...
Biker Posted June 4 Report Share Posted June 4 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. 1 Quote Link to comment Share on other sites More sharing options...
rgsheehan Posted June 5 Report Share Posted June 5 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. Quote Link to comment Share on other sites More sharing options...
rgsheehan Posted June 9 Report Share Posted June 9 Does anyone know if anybody else has posted Forscan (or other software) data showing the actual runtime voltages from the DPFE sensor? I have read the diagnostic procedures posted here and elsewhere and those check out for me, but I'm still trying to figure out if both my original sensor and new one are wonky, or if there is possibly something wrong with the wiring on my vehicle. That signal just looks so noisy to me. I have registered over on the Ranger 5G site to try and get any info those folks might provide. I'll post anything I find that appears as though it could possibly help us, (unless they shun me for driving a lowly Edge, and not a manly truck ) 2 Quote Link to comment Share on other sites More sharing options...
Biker Posted June 9 Report Share Posted June 9 I hear ya. Well, your post has me convinced that it as something to do with EGR too. Maybe even MAP or TPS. It is definitely some sensor contributing to engine management at low part throttle. I dont know much about newer systems, but I was doing my apprenticeship when GM started with efi, and EGR only came into play once the engine was at operating temp and in closed loop. I like the vehicle too. Mine is over 160,000 kms now and no torque convertor issues. At this point, if it goes, I will replace the whole trans myself rather than lose money trading it in for something with similar problems. I'm done throwing money at Ford Credit. My kids will get this car in my will! 1 Quote Link to comment Share on other sites More sharing options...
rgsheehan Posted June 9 Report Share Posted June 9 Any way I can get in your will? I'd sure like a shot at that Z28! 1 Quote Link to comment Share on other sites More sharing options...
Biker Posted June 10 Report Share Posted June 10 HA! It sure is a fun machine. I still have a bit of runway yet, so by the time I check out, it may have an aluminum 6.0 LS, coil overs and whatever other goodies I can dream up. Quote Link to comment Share on other sites More sharing options...
