So when a car leaves the  tunning shop pinging and is told its a bad batch of fuel then it goes bang who is responsable ?

You may be assuming it's the tuner who is only responsible for the state of the tune at the workshop (I.e. any detonation present). Perhaps it is because of a fault in a pump, injector issues or so on. That being the case the owner is best served to either leave the car with the tuner where the proper fault can be diagnosed over time or drive it very responsibly, as you can assume he has been warned as such by the tuner.

To go on driving it hard in this example, and with less than adequate fuel makes the owner totally responsible for the outcome.

Also taking this into account it should also be in writing and signed by both parties.

If it was not than it is thier word aganist his which we all know what can happen with that nothing.

moral of the story we dont need another tuner crucified or skeletons draged out of his closet!!!!

While it certain isn't proper for a tuner to let a customer leave without doing his best to address any problems, a certain level of responsibility must be weighed on the owner to ensure that if any problems occur that they take reasonable action to ensure that it is firstly driven safely and secondly returned for adjustments or repair inspection immediately.

If you're going to modify your car and run at higher power levels there are always risks so it pays to understand the ins and outs and take responsibility.

So would one use a dyno to do this???

If a tuner modifies the state of tune of the ecu from factory, via changes to boost and timing, then says the fuel is bad because it’s now pinging, then the tuner would be acting incredibly irresponsibly to let the client take the car away in such a state. That would be asking for trouble, and why we need sensible tuners.

In such a case, it would be much better to put the tune back to factory before letting the client drive away.

Too many tuners cause damage, and then say it had nothing to do with them.

Of course, the worst situation is when the engine “breaks”, then they want more money to fix the problem that they caused in the first instance.

Is that why plugs are changed???

Actually someone did fall asleep during the training. No names though!

As an aside I monitor the knock sensors while I tune, and get them to read zero activity during my power runs. I also tune most street driven Ts on 95 octane fuel to ensure the lowest common denominator. That way, it really doesnt matter what fuel they run on the street, the car wont ping. Simple as that.

You are joking arn't you

I agree in regards to a tune, although the customer can demand that they take the car, which is why it's their responsibility. If the issue isn't the tune, but modified components, then it's a different story.
