Software version 68733601AA - 98 MPH speed limiter

Edited:
Alright just got a small update from the Tech who came from head office in Windsor, ON. They are doing a PCM flashforward from an AC flash to AD. I wasn't provided the full flash code at this time.

This is to prevent over fueling causing the melting of the new catalytic converters. I asked about top speed or any other performance changes, but the tech did not seem to think it would affect performance.

These flashes will only be done if you are having issues it seems. I don't believe it will be across the board for all RHO owners at this time.

I did ask about a future AE flash update going forward and was told that unless it comes from a recall or if the owner has issues. It will stay in the AD flash even after a new flash comes out.

Hope this helps those going forward. I will update if I can get the full PCM flash codes.
how do we find out what flash we have?
 
Edited my above post. After speaking with the tech once he completed the PCM flash he noted it was a flashforward not a flashback. From AC to AD PCM flash. He mentioned there was an over fueling issue with the AC map causing melting of cats. I have updated my post reflecting this. -Joe
When you say from AC to AD, what’s the full flash number? Looks like yours is a Canadian build, so yours might be using NAFTA flashes, not 50 state flashes like the one this thread is about.
 
I've already ran a 12.57 @ over 105 mph.... I swear to god if my truck gets limited to 98....
You use a JB4 correct?

Chris

BTW how are the brakes ;)
 
I'm not sure if this may be related to this 98 mph flash business, but it is a RHO/3.0L HO specific recall. I believe it was mentioned in this thread. Its a safety recall that only effect 219 vehicle, and is searchable by VIN.

where do we search by VIN?

It’s only for export built vehicles, so the flash should be different than this one, it would be an ROW (rest of world) calibration, like this:

So the original file on my truck was 68641784AE.

Witech suggested the update path was to 68733601AA.

Jimmy is there a way to backdate and flash the previously loaded software? So I can sniff all variants?

No. You would have had to download the 6864178AE efd file for the J2534 flash application back when it was the current version. Now it’s unavailable for download since it’s been superseded.
 
Ooh. Where and how do I download the “efd” file with witech?

All RHO sold by official importers in Europe/Australia (AEC, KW for Europe) have a speed limiter due to Q rated tires. T rated (OEM 35 tires) are not sold or road-legal there (except if one gets special homologation ).

I’m aware
 
If that's true, it's unacceptable. That is a breach of contract. I intend on bouncing off of that 118 MPH speed limiter on a regular basis. It was one of the critical criteria that led to my decision to buy the truck. Vendor has a legal obligation to deliver as described. Would they accept $5,000 less than the agreed upon price for the vehicle? Why would any customer accept a detuning 'duct tape' solution like that? It's a slap in the face and will be a deal breaker for me if true. That would be enough to send me back to Ford.

On a percentage basis, this is less egregious than the MPG claims vs what anyone has reported actually achieving.

Ram seems very much in the "whatever it takes to make a sale" business.
 
I think this “update” is solely for export use only. Not applicable to US models.

My truck is going in for cosmetic repairs next week and they’ll get explicit instructions not to touch the computer and to ignore my DiabloSport 😂

This thread should be pinned. Thank you for starting it and sharing important information. Did my own research. Very vague and inconclusive, which I find unsettling. From what I gather, the service bulletin claims that some RHOs have the ability to exceed the electronic speed limit, which could compromise the integrity of the tires, being that they have a 118 MPH rating.

BUT THE MANUFACTURER'S SOLUTION TO THIS PROBLEM IS TO QUIETLY TAKE 20 MPH OF PERFORMANCE OUT OF THESE VEHICLES. To me, that doesn't make sense. 240 trucks were released with a 'computer glitch' that allows them to 'wander beyond' the electronically limited 118 MPH governor. Our concern is the tires, not some dirty secret with our truck. To address this problem, we've released a TSB that detunes performance by 20 MPH.

I'm not trying to offend anyone or stress anyone out but, to me, this sounds like it could be a cover-up. If 239 vehicles were released with this ability to wander beyond the electronic speed limit, wouldn't the fix be to correct the glitch and lock them into the 118 MPH limit instead of throttling them back to 98 MPH? Something doesn't add up. Something smells rotten in Denmark.

It doesn't matter whether or not you INTEND to drive past 100 MPH or not. This should be unsettling and troubling to every owner or pre-owner of the vehicle. What if this is a cover-up and an omen of a major engine flaw in some of these vehicles? Who does it affect? How far does the quality control problem go?

Here's a scenario that is PURELY SPECULATION; NO FACT WHATSOEVER, just to make an important point. Some vehicles 'drift beyond' the electronic speed limit. POSSIBLE TRANSLATION: We've discovered faulty wrist pins in the engines of many of these vehicles. It's too expensive to recall them all and replace the engines so we will QUIETLY attempt to side-step the problem by blaming it on computers and tires and apply an undocumented duct tape solution that detunes the trucks, takes away 20% performance and minimizes the chances of the engines coming apart due to wrist pin failure.

The VIN identifies which trucks have this problem and which do not - IF YOU ALREADY HAVE YOUR TRUCK!!! If, like me, your truck is still being built...YOU HAVE NO WAY TO KNOW. The recall only addresses those trucks that are out. Stellantis CERTAINTLY is not going to reveal which trucks currently being built have this problem!!!

What can we do? You can pull the plug or you can wait until your truck is delivered and take it for a test drive, BEFORE SIGNING, and drive it to 100 MPH to see if it bounces off of a duct-tape speed limiter or continues to 105, 110, etc. Great way to break-in a brand new truck, huh? And...your dealership won't have a problem with that, will they? Haha! Are we having fun yet??

I don't know what do to. This is above my pay grade.

Are software updates automatic or manual? (Never looked for a setting. Yet...)
