Thanks Tom. That's reassuring.

The shape of the graph comes from the data in the table. It's the scales and units that I'm not 100% sure of. Thanks for posting the ECUtune graphs, I'd been looking for them, but couldn't find them. I'm happy that they look fairly similar to mine.

I understand what you are saying about the map should be flat in low load as rpms increase. I'll check the code again and make sure I haven't got the scale backwards.

There are some other tables in the memory that probably have an effect on things. I don't understand what they do yet.
