Please contact our customer service at 888.972.2464, and provide your sales order number and VIN#. If your flash counter has incremented or your vehicle is experiencing a CVN mismatch, we can reset the flash counter and match the CVN to whatever you would prefer. The ECM state frame can also be reset as the need arises for those whom have not elected to select the transparency option when flashing.

Off Topic/ Please update to the latest Pfadt Flash: new features are developed and released periodically.

 

What are you talking about guy??? China?

Use the search function for christ's sake. This has already been covered a ton of times. Already proven false.

 

kiteboardr: It may be a little premature to jump to that conclusion, although I was guilty of thinking this myself about the tune.... but only to myself.

Nothing against anyone here, but Trevor is an unknown and joined the forum yesterday. His first two posts seem nice enough, but basically trash Pfadt publicly with no mention of trying to work with Pfadt to see if he was doing something wrong.

 

Kiteboardr you've brought up some great points!

We can set the CVN number and the reflash counter to whatever you want. This is a featureset currently unique to our flash loader solution.

The CVN number is neither the only verification of reflash or the sole factor in GM and GM dealerships denying warranty claims. The ECM state frame when cued from a GM MDI (or GDI diagnostics tool) will match the OE tune as is with a Pfadt tune.

We recommend that prior to taking in your vehicle for service that the vehicle be returned to stock as then the ECM will match all current and future GM checks.


I will not dignify this post. You're welcome as with any Pfadt customer to come tour our facility and see in person where and how our headers are made. We take pride in our products which we can proudly stand behind as 100% MADE IN THE USA.

 

Halfmoon, perhaps your right. How about someone from Pfadt post a video showing the ecu write count going from Stock->Tunded->Back to Stock = showing the ECU wirte count each step of the way. If they can prove their product does what their sales guy Eric claims, then will I apologize and retract my post, until then I am going to believe Trevor works at a GM dealership and would not have reason to lie?

 

So the Pfadt Tune can be used to defraud factory GM warranties?

 

Hopefully, I am not understanding, your post.

However:

If the above information clears the re-flash so that GM can not determine if the car has been tuned you maybe creating a problem.

There was another forum vendor who also had such a capability and I do not think it went well for him.

 

Halfmoon: please show me how I trashed Pfadt? Was it where I mentioned I was impressed with the upgraded performance?

My point here is that the Pfadt tune is what I used and what can be detected from using dealer supplied tools along with GM information supplied to dealers. After the tune is returned to stock, the ECM will report that it had been previously flashed. The tools GM engineers use are specially made to detect this, and according to a technician who has worked for me for 12 years, there is a separate module that records this information that is separate from the ECM and cannot be altered or reset.

Does this mean the Pfadt tune is bad? NO. It is great and the car performs much better with it. Can it be detected? Yes. Can GM see it was used even if returned to stock, yes. It is your call to do this or not.

Also, if using HP Tuners or EFI Live the same thing applies. Not bashing those companies either, just know GM engineers are not dumb and have put measures in place to reduce warranty claims, especially after the LS7 valve dropping issues. Think I'm lying? I've dealt with 6 blown LS7s in the past couple of years and I am not lying when I say only 1 of those motors GM covered under warranty. They gather all evidence and you are guilty until proven innocent.. And that's with me going to bat for my customers each and every time.

Just know there are great performance part companies out there, like Pfadt, and you the consumer risk your warranty when modifying your cars. This is more of an FYI for tunes on the C7 in general and less specifically about Pfadt, but it's the only tune I've used on my new car since. And I don't plan on taking it off because I like it so much.

FYI I used the Pfadt 1.0.3 tune and enabled transparency mode when prompted.

 

We do not want our tune to be known as providing a way to defraud anyone, and nor was that our intention. The features that we have provided are for diagnostic purposes.

What we want to be known for, and what separates Pfadt from our competitors is our R&D. We pride ourselves in providing products to our customers that are not only subjected to rigorous testing, but products that are at conception already leading the industry. We are the only company that will provides complete solutions, as apposed to just selling parts.

Look everyone, remain tranquil.

Maybe I am missing something but the PFADT post above advises "select the transparency option when flashing."

This sounds like an option to use prior to a flash in order to maintain static state on the flash, i.e. maintain OEM count number el al., and flash so it can not be tracked.

If this is accurate, and I suspect if PFADT is stating it, then it is very likely to be accurate, one only needs to select this option prior to any programming/flashing. May a bug disabled it? Was it in previous versions of PFADT's software?

Also, it sounds clear from PFADT that going backwards/'resetting' is possible as well, which will fix already done flashes.

By their posts, PFADT seems clearly wishing to discuss and resolve this stuff.

PFADT do I understand those portions of your reply correctly, about transparency and over-writing old flashes to 'new'?

PS: Trevor brought up a reasonable topic to discuss/resolve/question, as needed. No flaming in his initial post, at all.

Thanks

 

Yeah good call. Big surprise. No mention of him trying to work with Pfadt or calling them with his order# etc.

There is another thread on here where someone is trying to suggest ARH copied someone else's headers. WTF is going on with people basing on our reputable companies?

 

TevorVette, glad to see you online! It has been brought to my attention that your tune is not functioning properly, please provide your sales order # so that we can verify your order and assist you. I cannot find any record of any individual named Trevor for any C7 orders

It sounds like you love your new C7 tune, but even if you are very happy, which it sounds like you are, we want to ensure that every feature is working perfectly. We won't have it any other way!

 

This is an interesting response.

1) Why assume my name is Trevor? It is actually my sons name.. LOL
2) My tune works fine- did I say it didn't? I stated it works great. I stated GM can detect the tune while it's loaded and also detect if the car was flashed after. I am a service manager for a Chevrolet dealer. For 16 years. Use my information as you wish.
3) this tune was purchased from a local shop, who had a customer back from the deal, so they sold me it cheap. Someone at Pfadt made the tune file with my VIN and sent my contact at the shop a .pft file. It works fine and makes the car perform better, no bashing on your part and no need to assume I am lying here.

I am not sure why some people have flamed me claiming I am bashing Pfadt, now Pfadt themselves wanting personal information, which I won't give because I've already stated my job position and that would be risking my career. Not sure why my information shook the tree in this thread, but I feel customers knowing their warranties could be voided with a tune (BY ANY VENDOR) is something that should be known publicly on this forum.

Pfadt, no need to turn this around on me- but please don't think or mislead others to believe your method of tuning can override the measures put in place by GM engineers. The new PCM is high tech and they know what they are doing.

By stating you can alter write counts and make it look stock alarms me a bit. Say a customer blows his motor with your tune, and then returns to stock.. If the tune doesn't completely clear the flash timestamps will you cover the warranty issues if GM denies it? If not, why care in the first place?

If you want to put safeguards to disable GM's methods to check PCM flash history, Pfadt should do what Dinan does in the BMW world.. And cover warranty claims. What do you say, Pfadt?

 

Sorry, come again? You took your car in to get it checked out? How did you ask.. "Hey please check to see if you can tell I modified my ECM". Talk about risking your warranty right there.

Not sure why anyone would do that.

Nothing is wrong with the tune, for the 10th time.

I am willing to bet whoever "checked out your tune" didn't do much checking out then. If they are aftermarket friendly, as you say, that would mean denying GM engineers a system state download / image of your PCM so they could check it. I am assuming your dealer did not do this process? Did they send the image file to GM and let their engineers look at it? I hope not.

If your dealer is "aftermarket friendly" and willing to risk their jobs to protect customers, what is the dealership name than? Be glad you know a dealer like this, it's probably the only one out there because if GM found out they would be screwed.

What's the name of the dealer? You want me to post the shop I bought my tune from (and why do YOU care? Hmm?). Then tell is your aftermarket GM dealer willing to break GM rules for the sake of the customer. I'd love to pick their brain because I've tried everything for my customers.

 

Trevor,

Though this thread did get off topic, and I do not feel by you, it seems there may be a way for 'un-public correction' of your issue.

I suspect there are some ways for you, even with your current sentiments, to find a quiet resolution to your issue by conversing with PFADT off line.

I think if they have a way to resolve it, they will. If they can not, or won't, please let us know. And I do get the concern that you work for GM, so caution beware to a reasonable extent.

This post topic, though a good topic, is not worth the tension going into some of the comments.

Good luck.

 

We are working with Pfadt and Trevorvette to try and verify if there is truly an issue with modifying the CVN and have yet to verify he has a Pfadt tune or that the issue is present.

It is of the utmost importance to us that the community has the most accurate information and to avoid hearsay we will update this thread once any concrete information is provided by either party.

Trevorvette thank you very much for taking to the time to share this information! However, it deeply concerns us that after exhausting all of our resources, that we cannot trace the origins of your particular tune file. Please understand that every single tune file that is created, has a unique Sales Order # associated with it on our end. These numbers are tracked in several inventory systems as well, so this information is redundant and very accurate. Unfortunately, you quote as the origin of our tune the following:

There is absolutely no possible way that you are currently running a Pfadt tune. I personally handle all of the tune distributions for our customer orders. Every single tune file that our engineers create comes through my PC. You may have the Pfadt Flash program and the cable, but there is absolutely no record of us creating a tune file for any vendor in California (or the entire US for that matter) that then had us revise the tune-VIN as a standalone order. That is quite simply, not how the tune order/creation process works in any capacity. Therefore, as it stands now it is not possible that you have an authentic Pfadt Calibration. This is the only conclusion that we can arrive at by checking our records (tune generation, financial and inventory management), and since I have asked that you at least provide the shop’s name or even a VIN so that I can make sense of this, and you have refused, I have exhausted all reasonable options.

As it stands now,the Pfadt tune will not increment the write counter, and it will ensure that the CVN matches. This is a feature that ws very difficult to accomplish and that we are very proud of. However, I would truly hate to continue thinking that you are making all of this up. I hope that in the future you can contact us so that we can establish the facts in this situation and better serve both you and the Corvette community.

Best Regards,
Pfadt Racing
