NEW PTCM UPDATE FOR 6.4

[strokinpower]

Dealership called me today and told me to bring it in to get the new update that is supposed to alleviate reduced power, excessive smoke during regen, and unusual engine noise. I'm going it 1:00. I didn't mean to put PTCM, just PCM

Mine called me yesterday too to tell me abou it...Do you have a TSB #?

[strokinpower]

no, but I will get all the info on it when I go in today.

[muntu]

was the call outa the blue or were you on the books as havin complained about low power etc during regen?....because my truck in regen shows /feels normal...no apparent power reduction....so was wonderin if the recall gonna apply to all 6.4's or those in with a complaint.

i was at the dealership today because my factory alarm was screwed up and i asked them about any updates. i don't know when it came out but i'm getting my PCM flashed on thursday. the code for the flash is....11B23 Powertrain Control Module Recalibration...... i don't know if that means anything but that's what my paperwork shows. i don't know what it's supposed to change but i'm gettin' er dun.....

Ok, I got it done today as well as changed the upper rad hose because it was leaking. Not covered under Premium ESP. That cost, with 10% discount, $160.77. Anywho on to the reflash.... this is what it says it fixes...
"In some of the affected vehicles, customers could experience one or a combination of the following symptoms: illuminated Malfunction Indicator Light or Wrench Light, runs rough, reduced power, excessive smoke from the exhaust, fuel smell from crankcase, coolant loss, and/or unusual engine noise. These symptoms could be caused by concerns that may eventually result in significant engine damage and a lengthy, costly repair. Ford has developed calibration improvements to the PCM with improved fault detection capabilities that allows the vehicle to quickly detect and react to issues before damage occurs."

Also I noticed that the "Cleaning Exhaust Filter" message stays illuminated until it's completed like they used to.

I can't exactly remember what the Mechanic said but something that used to take its reading from the Exhaust Back pressure sensor is now getting its reading from 3 other sensors.

Do flashes like this affect trucks with tuners (will it mess up the files loaded by the tuner)? I don't have a tuner yet, looking at the mini max but just wondering what happens when they reflash you pcm when you have a tuner or are going to have one in the near future.

Just curious.

i am wondering the same thing since my truck is tuned?

Im thinking , if my truck is dpf delete and tuned, then All the problems addressed in the flash were fixed when I did the delete and tune..The new flash is their attempt to minimize some of the negative effects of having a DPF. It may help for those that have the DPF equipped truck?
