Engine runs very normal at idle but after 30 seconds my afr value rises up to 19/20 and engine almost stalls. To avoid the engine from stalling i have to push the gas padel slightly. Afr goes down to 14.7 and the engine runs normal. But approximately 30 seconds later the afr value rises up to 19/20 and engine almost stalls.
This keeps repeating till i turn off the engine.
I have tried it with the map from the 1.8 nbfl and a brand new empty map (just seted the right engine)
Then i disconnected the Emu and started the engine with the standard ECU -> works fine = no problems at idle.
Then i reconnected the emu and had the same problems as before.
Do i have to change some of the jumpers inside the EMU to work properly with the 1.6 engine?
I ran the same EMU on 1.6 and on 1.8: same jumper configuration, just different software config. (engine selection => B6 (NB)).
That sounds strange.
Are you trying to tune it using target AFR table even in closed loop/idle? In case yes, this might be the problem. If no map is selected, it sounds really strange
