and here the solution:

Could be that this approach works with the Keihin ECU.

BR, Tom
 

I took the 20222 stock exhaust map, which dyno jet uses as a base, opened the secondaries, upped the top speed to 250. Then I loaded the PCIII trim map for jardines. This gets applied when you download the tune.
 

thanks Tom. do you mean pulling the main fuse to reset the ECU?
I disconnected the battery for 10 minutes, same faulty state after that...
