BMW 335i HFS-3 install

[WhiteKnight]

Hello guys,

I just installed HFS-3 to a BMW 335i, its working without any errors.

The problem is its injecting too early even if i set the threshold to %60-65 level.

Is this a problem related with Direct injection? I heard that they have higher frequency compared to standard injection.

By the way;

1- I did not wire MAP sensor.
2- I did not wire the yellow D.Injeciton wire. (which is described as DI-connection in the manual). i just wired RED and GREEN wires for ECU.

Are these correct?

Also, can anyone help with the internal settings of the control unit for 335i?

Waiting for your suggestions,

Regards,
Emre

Are you using the red and green wire of the green harness?

[WhiteKnight]

yes i'm using red and green wires of the hfs3 ecu harness

[Richard L]

Is the red and green wire from the grey harness?

Question:
Is the HFS-3 circuit board Blue or Black?

OK.

You have the HFS-3 version. Recently we have include a green coded harness for the user port. This port is specially designed to read "Direct injection" signals. The 335i is signal profile/decoder is included with this unit.

Can you check if you have this harness (green coded) with your system. If you can give me the serial number on the controller, I can check it for you.

I DON'T HAVE THIS GREEN CODED HARNESS BUT I HAVE A USER PORT IN GREEN ON MY HFS-3
HFS-3 SERIAL NO= SN-10345
