Sadly, I had the recall performed, in Flagstaff AZ, and hate it. The truck was in for warranty work on #5 injector due to wiring harness issues, and the dealer snuck it in. How does driving down the road, at 45 mph, turning 1800 rpm sound? How does 12 mpg on the overhead lie-o-meter sound? I am currently trying to find a way to remove this piece of junk.

Lets just say that when a certain performance product rewrites their code for this piece of trash update, it will be installed.

The truck is an '07 5.9 mega cab 3500 with a 4.5" Fabtech lift, MPRB exhaust, True Flow intake, 4:10 gears, 35" Toyo AT's, somebody's tuner, and a slew of other things not relevant to this post.

Bottom line, avoid K01

 

Are you saying it effected your rpms? Even with an auto thats not really possible.

Also the lie-o-meter data gets reset when the factory does a flash, so it may take a while for the usage to change.

If your speedo was corrected before you will probably have to re-correct it.

Not saying it wasn't K01, just thowing out other variables.

 

Like I said on another post.
I know this was just released and several people I know just recieved the notice on sat. I haven't seen one yet.

I'd be Leary of this recall. It says it has to do with ecm issues and this reflash fixes it. Well I haven't had any issues. Hope this ain't a ecm lock up software update like for the 6.7's. Just saying theres a lot of 5.9 still under Cummins warranty. Just thinking here?????

If a Smarty update is needed from the 5.11B then I wouldn't get the reflash till Marco has the fix. Or we really know the reason for this reflash.

 

I buy the ECM issues.. like I said, plug any scanner or tool in that looks at the load and fuel flow is VERY wrong at low load and low rpms.. The liberty had to be fixed for emissions, not surprising that the trucks do too... Not saying it doesn't do other things, but there are ECM issues.. Anyone I know that has tried a ScanGauge on a 3rd gen 5.9 can tell you that.

 

Can you save the orginal program from the smarty to your laptop in case you want to put i tback. Im not going near this recall I live in WV and aint going nowhere near the left coast

 

AH641D:

My nephew flew those for a while. Now he flies Ospreys. To answer your question. When driving with the K01 update, in cruise control mode on level, paved ground, the RPM's will vary and go to 1800 @45 MPH. I do not know what the update is supposed to cover, I know what it did to my truck. The truck was at factory stock settings when it went into the dealership. It went from getting 18 to 19 mpg on the overhead lie-o-meter before the K01 "update" to 12 mpg after the "update". Of course I am not happy with this, and it is going back to the service performing dealer in 1 week (because they care so much about us customers, it is the first available date). That mileage drop is at around 300 miles in the vehicles normal driving pattern.

As for affecting the RPM operating range, why is it not possible? I have not decompiled the code written into the ECM, so I do not know what it really is doing. It certainly is possible to program any driving parameter with these engines. Shift points in an Auto, fuel air mixture, timing, injection duration, etc. Any of these variables can affect operational RPM's.

Unable to correct speedo until a certain aftermarket program company updates their code to rectify this K01 trash

I have had this truck serviced religiously, and have more than a little automotive experience, but have never been as disappointed with dealer work as this. (Unless you count the MG dealer in Denver around 1977 who would not warranty his shoddy electrical work - After all, Lucas Electric is the Doctor of Darkness)

I am looking for a way to remove this "software update" from my truck, and roll back to the previous version. This K01 "update" is about as professional as MicroSquish and their legendary service packs for the operating systems built in sand.

 

I'm all for improvement but this one seems not totally thought through. Sad thing is this country is so hung up on HP/TQ maxs not real reality. These trucks are able to do everything most of us actually bought them for and throw at them. So it would be nice that us diesel heads(consumers) ask for what can be done give us the power we have at hand(which is wonderfull) and improve mpgs with less restriction and emission. It is proven possible unfortunately us consumers control it with the wrong out comes (hense the 6.7 low mpgs higher hp/tq more fuel less emission REALLY WOW we can do better)

 

It seems that your trans isn't going into OD at 45 anymore, which would have you just under 1300 rpms (tq converter locked). That could be purely due to the speedometer error.

My point was that a flash can't effect the rpms at a speed, in a gear. Yes it can change the parameter for gear shifts and OD engagement, but you are still bound by actual gear ratios.

So your tuner isn't compatible now? Which one is it?

 

I'm curious how many of you that haven't received the recall flash paperwork have had previous flashes done?

I got my smog requested registration a week or so ago, and have yet to receive a recall notice. I have had a few flashes on the truck done, most recent was 1-1.5yrs ago, maybe my last flash addressed the concern? I know my FE went down.

 

I read on this site where a guy reloaded his Smarty without a Marco update after the K01 reflash. I'm holding off until registration time.

 

I still haven't received any recall notice, so I took my truck to the Smog Only shop that I usually use yesterday. They performed their tests and gave me my passing certificate. What was interesting was watching them perform the tests. I watched from the waiting room while they did the full throttle test (no visible smoke at all) and the visual inspection. My guess is that they had never done a smog on a Dodge diesel before. I watched as the first guy stared under my hood for several minutes before he went and got his boss. Then they printed a bunch of pictures off their computer and went back and stared some more as the shuffled through the pictures. After watching them for about 15 minutes I went out to see if I could be of assistance. One thing that was confusing them was the hose from my bypass filter coming into the oil filler cap, which I explained to them had nothing to do with the smog system on my vehicle. The pictures they had were of all kinds aftermarket manifolds, etc. Finally they just asked me, "Is this the way the engine came or have you modified it?" I told them it was completely stock, which is the absolute truth, and they seemed relieved to accept my word for it. These guys didn't know if they were afoot or horseback when it comes to smogging diesels, and my guess is that it will be that way at most smog shops for awhile. Anyway, I don't have to worry about it for two more years.

 

Just got an ECM recall notice in the mail, for 06-07 5.9s and 07 6.7's. How does the mfr find you anyway? I bought my truck used, private party, and it's never even driven thru the parking lot of a dealership since I've owned it. ANyway. I have the same thoughts, maybe they're conjuring up a way to go back and lock ECMs on older trucks that are still under warranty.
Mine isn't going in. Averaged 12mpg towing my 5500lb boat trailer about 700 mi last weekend at 80mph and half of it was into a 40+mph headwind/crosswind. It works fine like it is!

 

Bigiron did they plug their computer into anything on your truck?

 

I had my truck smogged last month and my experience was exactly like Bigiron. I had to show them where some parts are located. I had to point out the air intake heater. The tech had to look at his online manual for pictures of my '07 5.9L, as there are slight differences in various years. The tech did hook up their computer to the truck's diagnostic port, but was unable to read the ECM. He said their software was not updated yet. It sounded like it was their problem, not mine. He passed my truck after the inspection.

 

checked the VIN looks like they want me to do the Steering linkage recall and the out of park alarm Nothing on the OBD.... Yet
