Hey guys,
Heres the thing and the issue I got.
My car originally had AJQ dbw engine with 1 o2 sensor. Before I bought the car, 4 years ago - engine swap has been done from previous owner. They put AUM engine with the narrowband loom from the AJQ...and AUM wideband ECU ME 7.5.
I just got a PCM Relay error and lambda s1b1.......Car is using lots of fuel and doesn't run properly...It has 0.9bar boost but it lacks lots of power....
So, do I need to Wire Wideband o2 sensor OR I can use Narrowband ECU with existing wiring and nothing to change and just to run my engine as narrowband? Is that possible?
Can anyone help?
Thanks!

P.S I was given an advice from a tuner to make me a custom map Alpha N to run without 2 lamdas?

Alpha n is a backup mode if everything fails. Tune the car properly and fix the harness / sensors if needed.

Ok so heres what I did!  My AUM ECU and 1.8T AUM Engine had an AJQ Loom. So I have opened the ecu connector and wired PIN 71 and PIN 52. As I already have the existing pins for the Narrowband o2 5,70 and 51 which I need for the wideband. I will remove the 4 pin connector replace it with the 6 pin(which I got) Is everything correct? Thanks |

Okay, so I have sorted my issue, wired 2 new wires and got a new 6 pin connector for the Wideband, and car is running as it should again! You can lock it now.
