Over rev report

[UnhandledException]

Searched but could not find. Is there a way to see if a GT350 has been "over revved"? Does the OASIS report show this? I am talking about a mechanical overrev where the driver shifts to the wrong gear resulting in the RPMs to go beyond 8250 rpm. This is different than fuel cut off at red line. I know Porsches have this "DME report" that shows you each RPM range and how many revolutions the engine turned in each range above the redline.

I am looking to purchase a 2019-2020 GT350 but I am really having hard time finding cars. I have found less than 10 cars that match my criteria (Recaro seats and lighter colors) and none of them are driving distance. They would be sight unseen purchases. I feel uneasy buying a manual transmission car without an over rev report.

The Oasis is just going to show when and if the car was serviced at the dealer for warranty work. You’ll need a dealer to access the ecu for what your asking for. Me personally I wouldn’t be concerned with what your looking for. If the car has everything you want, meets your expectations, and still has the factory warranty your good to go. And if not, add the factory warranty and enjoy the car.

Thank you. Thats a bit risky. I honestly thought there would be a way or I should say an easy way to check the over revs from the dealer but after posting this, I have done some further research and it doesnt look like this is that easy to obtain.

The problem is if there was a mechanical overrev, sometimes the issue manifests itself a few thousand miles later in the form of grinding gears, noises from cams/valves/lifters which at that time Ford dealer might refuse to warranty as these signs are a bit obvious.

The PCM permanently records any event such as this.

What did you do????

Edit:
I see where you are going with this. You are buying a car. Any competent tech can see this as well as if there has been a tune on the car. I would absolutely verify this, because if the tool who had the car before you tuned the car and your engine blew, you would not have any warranty. VOID.

That’s a new one on me. Ford warranteed the Track Attack cars regularly. And they were used for a performance driving school. I get dillegence, but if your going to try and effectively say the warranty is of no use then maybe a used 350 isn’t the best choice. I’m assuming an unmolested 350.

The overrev code is stored on the ECU until a tech clears it, along with the other codes. It cannot be cleared by an owner using a standard obd tool/software. I know because I’ve had the code twice after track weekends. It was cleared by the tech both times while clearing the other codes that were associated with the warranty item I had the car in the shop for. I can only speak for my two experiences… but they didn’t care one bit, and it never made it onto the oasis or their notes about the overall service. Also, the code doesn’t tell them how high the revs got, just the fact that the RPM’s exceeded the limiter. The code is not permanently stored.

Question. Do you ever access your stufff with forscan? I do on all my Fords.

I picked up a forescan capable dongle at the end of last track season, but I’ve only used it for rudimentary stuff on the exploder. I’m sure it’ll get more use this track season given my maintenance history

My other two OBD dongles do a great job and are packed with features (especially the bluedriver) but it doesn’t allow software changes like the forescan does.

This feels like a really dumb thing to worry about.

Ecu records the OR code, ford techs clear them regularly unless they are looking for an engine issue related to that code.

AKA you will NEVER know if a car was over revved let along how many times, and had the code cleared no matter how long you spend time trying. So don't waste your time.

Just buy one still under warranty and then buy the extended warranty -
Or pay someone to check it our first (might even get a forum member to take a look for a few $s)
Or both
Nothing in life is certain but death and taxes

I dont think you can clear a permanent event. Some things are permanently stored.

I can confirm, these are clear-able.

 

[Tomster]

The way they catch the people who tune is with key on records. They correlate miles to key on events and determine a disproportionate amount of events. I dont think that is ereasible. I was pretty certain that certain events like overspend were permanent as well. You might be able to clear the code, but the event is permanent.

Agreed on the key cycles, that seems to be pretty well documented.

I just checked with my performance tech at ford. Overspeed is not stored in “permanent memory.” He said it’s erases instantly, and they couldn’t care less when they see it.

He also said key cycles are reset anytime the base strategy is flashed…. So software at the factory, a tune, or when you flash back to factory. They’re unable to change the key cycle counter .

I think we are talking about different things. Reading your responses here, perhaps what I am looking for is not even stored in this ECU. These OR event (which I believe is simply a flag that is set to true) is not what I am after. This thing you are saying tech can clear will set if you bounce of the rev limiter. What I am talking about is mechanical over rev that goes beyond 9,000 or even 9,500 rpm. Downshifting from 5th to 2nd instead of 4th near 7k rpm for instance will cause this. What I am looking for is how many revs the engine operated in this rpm and how many hours ago (in engine hours) this event occurred. This is what Porsche DME (ECU) report tells you, Corvette has this too, so does a BMW. There is no way to clear this information without installing a brand new ECU (which itself stores a code so you can tell ECU has changed).

I guess to some extent if there is no way to access this information thats a double edged sword. It also means if I buy a car that had a mechanical over rev, Ford wont deny the warranty because they wont know the extent of this over rev. The only issue here is peace of mind. I have seen technicians try and drive a GT350 (Ford ones) and as much as people like JAJ, Tomster, Tank, etc here are experts there are so many people who are complete opposite who buy these cars because of the hype and dont know how to drive a manual car. You may end up with a car that needs a new flywheel and clutch as well as throw out bearing in a week which warranty will not cover. My car nearly at 80,000 miles still has stock clutch and holds like day 1. Both me and my wife rev match since day one which is probably why it lasted this long.

Anyways, good to know this information. Thanks for the help.
