Difference between LAMBSE 1 and 2

Anything about Ford EEC tuning. TwEECer and Moates questions dominate, but there's some SCT and OBD-II knowledge too.

Difference between LAMBSE 1 and 2

Post by EFI66 » Tue Jun 05, 2018 4:12 pm

I have a hard time understanding the logs and why there is so much difference between the 1 and 2 HEGO

I run long tube Hooker headers and have hego delay at 24.

When importing the logs the numbers change from 0,87 to 873 on the HEGO2 side and at the same time the HEGO1 side can show 0,06 and 65.

Is it normal the commas just disappear and is it normal that the 2 sides have that much spread?

In effect the STFT1 can command a 12% increase in fuel while the STFT2 can command 4%

Is this normal?

A small difference is normal, but yours is quite large. A small exhaust leak can often cause the issue that you see.
