Hi, just wondering about reading files from already tuned software (revo, ie, um, Apr etc) can you read those files and look at what has been done to them, and modify those files or do you have to start from a stock file and tune from scratch? Coming from the falcon world where you could read other files so this is new territory for me with the mqb platform.
Cheers
No you can not read others tunes for multiple reasons not the least of which is the ethics of it. When you read for the first time editor will download a stock file for your ecu.Quote:

When you do a 'read' with VCM editor, it simply looks at the OS on the ECU and downloads a stock file associated with your car (VIN, controller serial).
So yeah, long story short, you have to start from scratch.
Ah ok. Very different to the ford and gm platform then. I?ve always had the ability to read a file, see what has been done to learn about how different tuners do certain things, trial and implement and see what works best for what I want.
So in the case that I read my file, flash it into the vehicle and it just doesn?t work out, can you reflash in the original file or do you need to go back to the tuner/dealer to flash that tune file back in?
If you pay for a license for an ECM you can flash it as many times as you want, including flashing back to stock at any timeQuote:

As was said above you can not read apr's file. That is their intellectual property when you try to read your ecu you will be supplied the stock file for your ecu. although there is debate whether necessary or not i would flash back to stock before flashing with HP. So yes if you are not happy with whatever you have done with HP tuners you will have to go to an APR dealer to get reflashed (APR TAX).Quote:
