Have you tried looking at your
mode 6 test id 53 comp id 00 - 0A
for your misfire data?

I believe the misfire monitors require
certain min max values to execute
such as rpm. (e.g., idle - ~2500).

Thank you for the reply. I guess I thought the MF1-MF8 data items were the mode 6 data for the miss fires. Correct me if I am wrong about that. If not, how are you accessing the mode 6 data in TORQUE? (thanks for any tips).

I am not familiar with the limits but I will look the software over further to see if I can find that area of the program as you mentioned.

For Torque Pro use Test Results icon
functions for mode 6 data.

The Ford OBD Summary for your model
year lists the tests and criteria.

Search "Useful Links" to find post of links
that will take you to the Ford site.

Capp,

I found the mode 6 data under the Test Results section listed under TID and then CID's - but of course and don't apply to my V8 engine and they show up in red. I noticed that there is no data showing up for CID through . The CID shows up and is green and says OK but the data value for it (current value 981) never changes. I never see thru update.

By the way, I am using the BAFX ELM327 with firmware v1.5 if that makes any difference. I had read that this adapter works with Torque (from another user) but perhaps not for all data? I hope this is not because the adapter doesn't work well.

Today driving into work, the "MF Total" gauge that shows up under my custom screen in the "real-time information" section showed a count of 2 misfires. As I said earlier, I have come to believe this information is likely correct. Oddly enough and at random moments, MF1, MF2, and MF7 showed up as 3585, 3841 and 5121 respectively - but not at the same time. They seemed to just show up one time and at different times from each other. I'm not sure what to make of that and I'm not sure those values look valid. Something is definitely amiss.

Any additional thoughts anyone could share on this are appreciated.

Jerry

UPDATE: I did notice this morning my fuel tank was pretty low and according to the Ford OBD-II write-ups, the Exec on board the ECM will suspend the misfire testing if your fuel level in the tank drops below 15%. I'm not sure I was that low but not sure I wasn't. So, more testing but I did drive into work this morning with a full tank and that's when I observed the behavior described above.

I believe the misfire pids are the raw data whereas
the mode 6 data is based upon the misfire
monitor results. The monitor is looking for
misfires that can cause serious damage to the
catalytic converter(s).

I have purchased (4) BAFX adapters as well that have
proven to work with the older Ford PWM protocol.
Some cheap adapters fail at PWM. Your pid data
should be okay if you successfully connected to
your vehicle's pcm.

Serious misfires should trigger a DTC.

Capp,

I need to understand your terminology a bit better.
When you are referring to the PIDs are you referring to the Test Results data section or the Real-time Info section. In Test Results I am looking at $TID 53 and in Real-time Info I am looking at MF1, MF2, etc. which ones are you calling PIDs and which ones are you calling Mode 6 data?

I was under the impression that the data under Test Results and test $53 is the Mode 6 data. Is that not correct ? If so, what are MF1, MF2 and so on ?

Jerry

Sorry for the confusion... parameter ids (pids)
are usually associated with mode 22 calls e.g.,
your extended pids that were added under
manage extra pids/sensors settings (real-time).

Test results shows your mode 6 results.

Ok, thanks.

So, the sensors that are available for selection in the "Realtime Information" screen that are labelled like "Cylinder 1 Misfire count" and such and they show up as MF1, MF2, etc, what are those? That is to say, where do they get their values? With my Mustang they show up as black (not green) when I am adding them to the screen which I would think means they aren't present and yet they do sometimes update with values but very infrequently.

Also, any idea as to why under "Test Results" I see test TID $53 and cylinders 1-7 (CID: $1-$7) as _blank_ in Torque Pro ?
Number 8 shows up as green, says OK, shows a value of 981 and never changes.

Jerry

Most of the extended pids for Ford
were from 6.0L owners. While some
of the pids work for other vehicles
some may not.

If you were connected to your pcm
when you added your real-time displays
they should have been green if they were
actively working.

I believe the real-time pids for misfires
are counts whereas the mode 6 data
looks at those counts over time before
setting a DTC depending on severity and
other criteria to enable the misfire monitor
to run.

For the mode 6 data... it is my understanding
that Torque is returning what your vehicle
is reporting. Ian, the developer of Torque, is
the only person whom can say for sure.

Note: I am not an expert... just another user.

Thanks a lot Capp. 🙂

Well you obviously have more knowledge in this area than I do but I am learning and really appreciate your help.

I understand your comment about it showing up green on the "Test Results" screen under TID while the engine is running and I am connected with the OBD-II. That makes sense to me. What's kind of odd is that 1-7 show up black but 8 shows up as green. Of course its value doesn't change so perhaps that is a false indication.

I have heard that for some early Fords the misfire data is reported under TID 51 instead of 53 . I wonder if the developer has experience with this and could tell me a way to customize one of the add-on codes you can create such that it might pull up that TID and it's related CID's? Hopefully he will have time to respond to this thread.

I am hopeful too that the developer can tell me how the MF1, MF2, etc displays under Real-time Info are sourced; that is, how they obtain their information. (Update: I think I found these under the special PIDs section of setup now)

Torque Pro looks like a fantastic tool for Dx your engine. Already I am learning a lot about my Mustang.

I have the problem where there are misfires at very low RPM (sub 1500 RPM) and that's one reason I am wanting to look at individual cylinder misfires if I can. The engine is fine and pulls strong once you get above 1500 RPM. It just has this awful miss if you lay into the throttle at the lower RPMs. I have replaced COPS (for another reason) and have checked for vac leaks but all looks good.

Thanks again Capp. You have been very kind to answer my multiple questions and I appreciate that!
