Hello everyone. My name is Daniel and I come from Germany. I drive a Golf 5 GTI bj 2005 with a BYD from 2008, a TTE480...

I have been driving with the data from a tuner for about 7 years now and have never been really satisfied. So I want to learn to adapt it bit by bit to my needs.

Now I have tried to drive with Lambda 1.1 at partial load up to 55% . To do this I changed the three LAMFA_0, LMFA_1, LMFA_2.

I looked at KFLBTS_0, KFLBTS_1, KFLBTS_2 and I don't think I need to change anything here.

The control unit does not seem to be able to do this. While driving I could see that it was always trying to keep Lambda 1.0. Always. (partial load)


I will provide you with the data.

I would be very happy if someone would like to help me.

Okay, I think the problem is that the ECU only runs on "homogen" and therefore a maximum of lambda 1.0 is possible.

Can anyone tell me which maps I need to change so that it runs in homogen-lean at lower speeds/load? BDEMEN

I have already tested a little but it does not seem to work. Lambda is maximum at 1.0
