Hello mates

I have a problem that I can not solve.
Car is skoda superb 2011 with edc17c46 ecu.
I use ECM original and see 1 map ( 0x07D129C ) that I can modify.
I set 900 rpm insted of 800 and 750, but no luck. When car heats up to 90C rpm falls down on 750.
I also tried to change idle with coding but it gives error all the time.
Below you can see map I tried to change.
597789597790
Maybe there some more maps that ECM doesn't see? Can someone help me with that?
Driving this car on 750 rpm from start is terrible in traffic jams, it has a very nasty vibration (all engine and gearbox mount are brand new, injectors are ok).
I will add original and modified file in 1 archive.

Thanks for help!

ECM shows 1 only. Can you give address of second one please?

I tried that solution with temp axis. Doesn't work. Still 750rpm:crushed:

I wrote to Alientech and they reply that don't have information about it. Anyone can help me with this problem?
Maybe some coding needed or so?

Test and report please.


Thanks for trying but it doesn't work and shouldn't!

Have you checked fuel pressure when it's hot as failing pumps have issues when hot

All parameters are ok. I checked everything with diagnostics watching on rail map. The same car like mine has identical problem.
Low rpm are programmed somehow in ECU. Maybe I need coding, but I don't know how to make it. Delphi/autocom gives such parameter to raise idle rpm, but procedure ends with failure.

Reporting.
I tried your file. When coolant heats up to 90C everything works perfect. 900RPM.

I was very happy to see normal rpm for tdi. Took a car for test drive, after 20 min of city cycle driving rpm falls down on 780 rpm again.
600256
I leaved the car for 10 min, after I started it rpm was 900 again. I drive for 5 min and it falls down at 780 again.
I think the problem is in oil map, because when oil heats up to 80+ degree Celsius, I have this terrible 780 rpm which are to low for such heavy car.

I also tried to code idle rpm with delphi but it gives error.
600259
I choose 860rpm (maximum what's available)
600262
P.S. I checked all sensors like map, maf, rail pressure and injectors (all deviations are +/- 0,3 mg per stroke).
