How can dealership tell if tune was loaded

[FIVE-OH]

I was talking about this to a guy I work with. He said we'll buy another ECU
Swap out the original one, do what you want, if you have issues put the original back in and go on about your business with a never flashed ECU. Have no idea how cost effect or prohibitive it would be

Not sure how well this will work with the car running on different ECU codes and strategies...

It won't. Plus as already mentioned you still have PATS to deal with.

Here's a question, guys that go from quto to stick or vice versa and grab an ECU from the kind of car they are cange to, why don't they have to have ford program it?

Already answered that one, you have to disable pats. Otherwise the car won't start. If you want pats enabled it has to go to Ford.

You could buy one and prove everyone wrong.

Disabling PATs in the PCM isn't going to make it start. The cluster is king shit on the CAN bus. It stores the keys, it also stores the unique ID of the PCM. When changing the PCM you have to do a PATS parameter reset. This does nothing to the PCM other than to tell it to send its unique ID to the cluster, which the cluster than stores.

Exactly^^^

I went through same scenario after my auto swap. Long story short... Shop doing the swap never did the PATS reprogram and I had an emission issue with their tune. Ordered a known good emissions tune from Brenspeed, but I had to get the PATS reprogrammed at a dealer before it would work since they would not disable it and the post swap tune had it disabled.

Goes back to the old saying you gotta pay to play. I've learned Fords warranty is bullshit anyways. I say if you got the coin to cover damages, then mod the hell out of it and never look back.

Voiding my drivetrain warranty was one of the most fun things I've ever done

Own your actions, don't try to find ways to screw Ford if things go wrong.

This is a Copperhead thing?

I have a friend who has unlocked all sorts of goodies in his Bosch pcm. He builds his own ribbon cables, pogo pin sets, solders on boards. I'm pretty sure you could doctor the system to do or say whatever you wanted fairly easily.

I'd never bother, just drive the car. Put slicks on it and run low 12's with a paper filter. My supercharger went on about 1000 miles after my warranty was up.

/\/\ Most people are not on that level though. And that is still a lot of extra work when what you should be doing is owning what you break.

and really, its not that bad. the stang is pretty good at taking extra power and abuse. And getting warranty work done by ford is not like subaru or mitsubishi where if you have an intake they won't warranty brake repair. Or god forbid Nissan who can void a warranty for you using a feature that was designed into the car from the factory.

It is so much fun buying a car and explaining to the salesmen why you don't give a rats ass about the extended warranty. When I got my stang the salesmen still spent like 15min trying to explain to me why I need the extended warranty after I explained to him that they aren't going to do shit for me when they see what I do to this car.

I never dealt with 3V cars, so maybe doesn't apply the same to them.

So the PATS disable doesn't work? I am working on a new ground up '69 with a whippled coyote and a 6R80, we already got the complete wiring of a '13 but was hoping the PATS would work as it has always worked on every mustang before, if not, looks we will get a cluster to hide somewhere and a PATS ring with a fixed transponder to it (if we dont get the ring to work on the column) Hope this is not needed.

There are PowerPC cars that work with IC stored keys, is not related to the type of PCM but how Ford decides to lay the PATS system out.

We have a log viewer on the IDS for mazda that can see everytime the pcm was reprogrammed or anything came up. Dtc's clear cycles all that crap. I'm sure ford has the same thing.
