Can I perform: misfire monitor neutral profile correction?

2012 Mustang GT, 5.0, manual transmission.

I will need to change the clutch soon, and the service manual calls out performing a "misfire monitor neutral profile correction," after all the labor is done.

I suspect that I can do this with FORScan but it may be called something different in the options.

Has someone here performed this correction?

How can I do it?

I have not seen that test in Forscan when connected to my '13.

Do you have an SCT tuner? That device has the "crank relearn" function and it WORKS RELIABLY. I've come across some threads on the net that stated even Ford IDS had issues with this function, and you end up with a "crank sensor not learned" fault that won't clear. I ran this test from my SCTX4 when first got the car running, and all went well.

That said, you probably don't "have to" do this procedure, and there won't be any issues after the clutch install.

I don't have an SCT tuner and was hoping to avoid the fiasco of buying one of those units, in favor of FORScan, to keep that extra $400 in my pocket.

Thanks for the help!

I think you will be fine without doing the reset.

Bringing this back from the dead...

Would love to see this capability added soon. I just had the crank pulley replaced on my 2015 Mustang EcoBoost, and the dealer forgot to perform the relearn. Now when dropping below 3,000rpm, it will sometimes trip a CEL right at 2,965RPM for multiple cylinder misfire, and I sure wish I didn’t have to revisit the dealer to correct it.

I agree with this request. I replaced my transmission and installed a new torque converter on my Flex and needed to do this calibration. I ended up having to bring it to the dealer as I was getting misfires on many cylinders before the work was done. No more misfires now that the calibration is complete.
