Idea for covering up a tune...sorta..

[MAGS1]

Unless :

1. Access the ECM: Gain access to the ECM, which typically involves removing it from the vehicle and connecting it to a specialized programming device or a computer with appropriate software.
2. Modify the software: Locate the software or firmware that controls the key counts within the ECM's programming. This could involve reverse-engineering the software to understand its structure and functionality.
3. Disable or hide key counts: Once you've identified the relevant code responsible for displaying key counts, modify it to either disable the feature or hide the counts from the user interface. This could involve changing the code responsible for displaying the counts or altering the software's logic to prevent it from updating the counts.

I admire the ingenuity. Two thoughts: 1) how many people actually have the ability to do this? 2)the dealer will still be able to see that the ECM has been tampered with, especially if key counts has totally been disabled and/or hidden. And then you get denied for tampering with the ECM.

You could change the logic to when there's a plus 1, it'll subtract 1 so net result of zero counts. They'll never know in theory.

True, but Ford is surprisingly lenient about covering warranty claims on FP tuned cars, even under the normal 5yr/60k powertrain. As long as that's the only obvious mod. A few people on here have had engines replaced with no questions asked. I would wager it's because Ford wants to keep the reputation of their FP division in good standing.

I would disagree with this statement since I had my FP tune installed by an ASE certified tech (my certification expired in 2015) and the part of the tune that should allow me to change tire size and axle ratios as well as misfire diagnosis and octane adjustment does not work at all and never did since installation of tune. I registered it and did all that was required to have FP warranty but called FP tech and was given the run around for over a year with end result of them telling me since car runs fine and no codes are being set and speedo is accurate that it's not an issue they will do anything about.

They first said they would give me a Procal 4 tuner (mine is Procal 3 tuner) for free when it was released but I would have to pay dealer to return my PCM to stock tune for me to install the Procal 4 tune. I argued that they should cover that cost since the tune never functioned as stated but they would not cover costs. So that's where it ended as they would not answer my calls after that.

I will never buy any FP product ever again and tell everyone I can about their piss poor service.

So much for keeping their rep in good standing.
