Chiptuning X5 E53 4.4i

[Supr4]

Hello
I'm new to the forum.
I would have liked to know if the tune I got is good.
It's an ethanol tune for my old X5.
I have the feeling that It consume far too much gas and loss of torque specially on hills.

Its not a tune its only 20% added to the lampda map

oO really nothing else ? Not even cold start or something else?

E53 4.4i = M62B44TU = ME7.2 = no widebandlambda so no lambda maps... its fuel injection in ms

Ok I understand.
Would you be able to make me a good remap with the different tables modified ? Im fine if it's not free I'm just looking for a good remapper I fail to find one

[Supr4]

No one can help me ? It seem this car is hard to remap or too old for remappers to bother idk ��

Double post sorry navigator mistake

[Lambda1]

e85 not as common... need logging and finetune, nobody will do free. Not this 30-40% shit to hole file or constant.

[Supr4]

I'm fine paying.
Do you think you can do it ?
If only someone had done the fine-tune to the same car and can sell it to me :/

[Supr4]

But I wonder if you don't change lambda/afr target how the car will know if it's too rich or lean since with e85 it's not the same ratio? You meant you need to change both?

Someone made this map recently I wonder it's a good one
Edit: tried it and it stalls as soon as engine start
