As a side not here. AdrianD is without doubt the man to ask the detailed questions to. I am just starting out with car ECU tuning, but learning fast. I do have a strong history of writing and modifying machine code for industrial equipment, but never a car so far.
If you just want to view your tune you need the MPPSV13 and its software to get the maps out of your car.
Then there is a free version of a program called WinOLS. This allows you to view your maps, but you do need to set up the maps using the addresses provided earlier, or merge someone else's tune that has already got the maps defined.
From that point is where you want to make some changes.
So there are several options here. From programs called "hex editors" to proper packages. The paid version of WinOLS will allow you to change and save your tune. I am cheap, so trying to do it for as near to free as possible. I have started using a free version of a program called VAG EDC15P+ Suite. It is not specifically designed for our cars, but does allow maps to be viewed, changed, and saved. It is slightly harder to set up than WinOLS, but I haven't actually played with it too much yet to see if it is just me.
Once you have saved your your changes you need to fix the "checksum". The most common method for this can't be discussed openly on forums it would seem, so I won't.
This is why I am looking for another free way to calculate the checksum. I am not putting that much effort into this right now as I still need to wait 2 weeks for my MPPS to arrive. It will start becoming a bigger priority soon, but trying to get my map builder working as I think it will help get changes done more efficiently.
AdrianD. Please make sure you correct me with anything I say that could be misleading or wrong. I want to share everything I learn, but not lead anyone down the garden path.
