I have a Glowshift wideband that came with the car. Today, I hooked up the 0-5v output from the wideband to the rear o2 of the ECU following these instructions:

It will show up in evoscan, but the AFR number doesnt match what the gauge says. Does anyone know what formula to use for the glowshift wideband? It uses a bosch 4.9 lsu sensor.

 

What is the AFR range for the gauge?

 

try 0.0274*x+9.0 in evoscan.

or 0.03928*x+9.0

 

i have the same gauge in my car and i was wondering the same stuff here what ecu pins did you use from the data log wires? im asking cos my car dont have rear o2

 

Where did you find ECU pins? I can't find them anywhere. I'm thinking though, why can't I just tap directly into the ECU? If anyone has any pins LMK! An is it possible to log via evo scan without obtaining ecu pins?

 

spoolinup has em

 

I just cut my rear o2 wire going to the ecu and spliced the wideband in. The formula that worked best for me was 10+(20-10)*x/255

 

And formula is accurate?

 

Yes

 

Hooked it up and smashed in that formula in evoscan and BOOM! It's works spot on!! Good work rlee!
