Hi,

I need to learn and info here was a great help, not much Information for this old controller can find online. Need to work with Tunerpro.

I have a screenshot from a driver (Titanium), there are differences to the xdf i found here. Can anyone help me to understand more?

1. Ignition Map1 16x16 - 14x16 why?
2. Checksum 007C00 Add:FF 8bit, Need more info...
3. Adress C10 16x1

I need to add the things to Tunerpro xdf and work with this. In future i need to figure out what the other things are and add it. But its not easy i am new.

This engine (AAH) has a switch intake (Saugrohrumschaltung in german), switch the length from long to short at 4100 UpM. Is it possible to find the point and change the switch UpM? The engine is mechanically tuned and the point must set different... How can i find it? Think this is a big thing?

Has anyone more/ other info from this?!? Is there a tutorial online for handle checksum calculation? Sorry i found nothing...

Please look at the files. When need more/ other info, please ask!

Thanks for help,
Stefan
