Flash and Warranty
#33
Good challenge but I do not think you will find them on this small forum. If you are worred about this you should pick out some Porsche dealers across the country and call them and ask.

I'm not too worried, for many of the reasons Ron mentioned above. Just wondering, as I figure there are plenty of members here that have flashed their ECUs and would have direct experience with warranty claims.
Softronic makes the claim about being undetectable quite strongly, and I'm sure this claim has swayed many buyers.

Another challenge would be to hear from the Porsch service techs that frequent this board and see if they will chime in on whether or not ECU flashes are detectable.

I should have been more clear - if ECU is returned to stock (e.g. with Softronic software) is there any residual evidence that can be detected by the PWIS that the ECU had been previously modified. I have heard that the answer is yes and even if you use a clean, replacement ECU the info in the ECU (operating hours, etc.) won't match to the odometer. I use ECU and DME interchangeably - I think the correct name for the "box" is DME. Thanks.

I am unaware of any tuner that offers the same.

This is absolutely not true. That is why several of the tuners that own the right equipment can claim that if they return to stock, there is absolutely zero chance of detection. Again, everyone has to do their own research and be comfortable.

Are you speculating or do you have info? Here is my supporting evidence. DME readout of a tuned 04 GT3 using newer PIWIS...reflashed to "stock."

Not sure why it's "absolutely not true" - looks like the opinions so far are from Porsche owners not technicians. As I read the tuner claims, they say they can return the ECU to stock. As far as I know no tuner claims there is zero chance of detection that an ECU has been changed, then restored to stock. You're right, we all have to do our own research but I'm not so ready to absolutely say yes or no to the questions at hand. BTW, I've had Ruf tunes even with the P-car still under the original warranty so that was my decision after research. I wasn't overly concerned if the tune was detectable or not. Still, this is an interesting topic. One day we may find the truth.

I've seen it in person on 07 997 products, zero evidence anything was ever changed, confirmed by using PIWIS. It all depends on how well you know your way around the equipment, hard coding, etc.
Remember, the car's computer is just like any other. It has memory in it and if you know what you are doing, you can truly wipe data and restore data to exactly how it "looked" before anything was changed.
One more time - everyone needs to be convinced themselves. If uneasy about any of this, best to not touch anything.
