Title: MED9.1 Commanded Lambda Spike during WOT Post by: norris_83 on May 29, 2020, 02:56:28 PM Hi all,
I've been tackling an ME9.1 ECU where I am facing a lean spike under WOT. Fuel Rail Pressure now stays steady up to 15.05MPA then it hits in. I did have a throttle closing problem going on but a friend managed to work out where the load limitr function was. This is not a boosted vehiccle from factory so I know there must be plenty of tables hidden that I can't find. I have tried 2 different Map Packs from Dimsport and BC consulting with no luck. Any idea what may be going on? Title: Re: MED9.1 Commanded Lambda Spike during WOT Post by: yxx499 on May 30, 2020, 02:18:11 AM What car it is ? 2.0TFSi ? Where are the logs, please?
