Tuned GT Question

[Rolls]

I had a similar experience. I bought my car used and it apparently had a tune on it when I went in for repairs. Their computers couldn’t connect to the car. They took out the PCM or ECU and gave it to one of their specialist to load a stock tube. Took about a week. It cost me a pretty penny. Don’t remember how much.

PCMTEC Pro tuner + OBDX VX (the cheap edition) + return to stock (1 credit) is your cheapest option to return to stock.

Much cheaper than Ford and you can sell it all afterwards (cable and software) if you don't plan on tuning your car.

Got links to the PCMtec pro tuner and OBDX-VX.

At some point I may want to go back to stock from my FP tune to use another tune program. Ford does not allow 18+ ecoboost owners to return to stock calibration with their program, do allow all other Ford vehicles to do so from FP program.

I should have all the parts soon. I’m hoping it’s as easy as it sounds and I can return to stock - for now.
I never thought about selling the software- didn’t know that was possible because of the registration process.
I will probably keep everything, just in case I need to adjust something later.

Its not advertised or allowed in our eula however we allow it within reason. Eg cars being sold, or you simply are not using it anymore. Reselling access or multiple people using the account is not allowed (unless it is commercial use under the same company).

Just a quick update, as best I know so far: I used the PCMTec software and OBDX connector to check the tuning on my vehicle that the Dealer cannot connect to.

the PCMTec software had no issues connecting. The file was easily readable, but I didn't see any changes. The file was not locked or obscured as might be possible for Tune-Locked PCM. I could see graphs of response curves and whatnot. I saved the file and also ran a Compare between that file and the stock file I downloaded from Motorcraft. The comparison flagged a least a dozen undefined tables. I clicked on the tables and there wasn't much I could glean from them. There was very little plain english nomenclature to identify the table.

I went ahead and flashed the PCM with the stock file, and it started and ran fine. I am not convinced there was still a tune in there, but maybe the PCM was locked by a tune that was removed prior to trading?? I just don't know.

Next step is to go back to Ford and see if they can complete the recall for the Brakes. If that works, than I am done playing with the system for now...

How much did the setup run you? Seems nice to have.

All in was less than $500 US.

Just a thought but if the dealer hasn’t done anything to flag the warranty yet due to a tune I would just carry on especially with such low miles on the car to start with. To me they can’t prove the car was tuned if they couldn’t connect to verify any parameters including key cycles.

And with such low miles if you ever did have a warranty claim down the road the number of key cycles wouldn’t be out of a reasonable range.

Another trip to dealer and no joy. I’m reaching out to PCMTec for advice.

The technician mentioned aftermarket wiring at OBD2 connector. I was nervous but raced home and investigated. The were two wire taps , but no wires connected. I pulled the kick panel to be sure nothing remained and found nothing.

Their is a good possibility the tune wasn't all that was modified. I seen/heard of people supercharging modifying their car and then when they want to sell it, remove every modified part and put back to stock. Except Dealerships can tell if your pcm was ever altered which could void certain parts/systems from warranty. Good Luck

Hello; Just read thru this thread. I do hope the issues get worked out for the OP. I do not have any suggestions or advice. I do have more general questions. I look at used Mustangs from time to time. So far, I do not consider cars with an advertised tune. Such is fine if a tune is known about. I sort of gather the OP though the car had a stock tune. My first question is what, if anything, the Op could have done during the pre-purchase inspection to find such an issue?

Say I find a used car with a known tune. What steps need to be taken with regard to dealing with an after market tune? Do I ask for some hardware/software?

Good luck to the OP.

That’s the challenge of a used car. The only thing that reassures me in this situation is that it had less than 2,000 miles on it and was only in the prior owner’s name for four months - before trading it at an MB dealer.
Someone trading in less than six months MIGHT drop serious coin on major mods but most gear heads probably wouldn’t.

my first thought looking at the connectors sunder the dash is radar detector but OBD2 is a dumb place to connect. So not sure what else only needs two wires- dealer thought maybe a remote kill switch for a buy here pay here deal. Not sure.

2000 is definitely a positive thing but, why would anyone buy a tune for a 'Totally' stock mustang. The benefits would have to be close to negligible.
