Thread: Wideband readings

Finally got my wideband installed today and was I surprised with what i found

Idle was around 14.3 to 15.5
Cruising was around 14.0 to 15.8
Wot was 9.1 to 9.5

What do you guys think of the numbers.
Also I ran the numbers on my jwt and it seems to come up as a 1.6 ecu. Anyone ever heard of a 1.6 ecu on a b14. Also my idle sucks but that's hopefully a different issue.

B14 with avenir swap.

wot is really rich, you want 11.5 or so, idle and cruise is ok, but has a big range , do you have an adjustable fuel pressure regulator, if so what is it reading. does your ecu still look for the stock o2 sensor ? how is your coolant temp sensor.

maybe you can also reground your maf, and make sure your using the correct injectors that match your ecu

I'm getting my nemu next week or this weekend. I rwgrounded the maf but I'm going map anyways next week. I'm installing new coolant sensors tomorrow. It has a nismo fpr set at about 58psi and it says 4bar on the very very faded sticker on the ecu
