Hi,

I have built a DIY-WBO2. And i want to know where i have to put the sensor???

Right Now it's located 6 to 8 inch after the turbo. The problem i have is when the car idle, it's look that it give me a good output. Seem to be 13.9 to 14.5:1. But when i floor it and go in boost, it's LEAN. And when i said lean is near 20 to 22:1 almost free air. I'm 100% i'm not lean in boost. So Is it possbile that the sensor is too close and gave me a wrong output??? Or it's the WB itself?

Thanks

dont know if you have a problem or not but aem says 36" away from the exhaust valve in their instructions.

 

I would go no closer than like 18"-20".

 

I had this same problem with my setup, the sensor was too close to the port and would overheat, giving strange readings. The Techedge will actually go into an error mode when this happens, not sure what others do.

For turbo they say that 18" is the min, for NA it's 24" and preferably further in both cases. Depends alot on EGTs.
