I have a wideband it uses a Bosch LSU4.9 UEGO Sensor it has a 0-5V output wire.
Depo gauges arent really sold here in the US so its hard to find info.

(0v=10.00afr)
(5v=20.00afr)

it comes with a chart with the volt to gas afr

Ex:
V AFR
0.16 10.32
0.31 10.62
0.47 10.94
ect.

I wanted to know how i can log from it. Can i splice into my ecu rear sensor? i have a test pipe so i dont need use that sensor anyways.

Currently i tried doing it as if it was a AEM i made the cable Serial to USB and that didnt work. Is the formula in EvoScan different? How do i go about logging from my wideband.

 

Got this fixed. Wired it into the read 02 ecu pin and used same formula as AEM. Works great.

 

I'm trying to do the same with a prosport wideband

Can you post more details on how yo did it?

thanks

 

Bringing this back.

So what i ended up doing is Apply the Rear O2 Sim Patch (Comes with Tephra V7) Then i found the pin that gets info from the rear O2.

I put the output wire from my wideband into the ECU (Rear O2 Pin)
Then on EvoScan instead of using 3C like ive seen on some threads i use 12. (MUT 12 changed to 8409.

Now with all that done im able to pickup my Wideband.

HERES THE PROBLEM!! ...... Ive tried so many formulas to get the gauge to read the same as logged and its been a pain. Also what people use seems to be different for most...
