Wideband problem in tables please help

[Lookout22]

Hey guys I’m kind of new to s300 I’ve got a 97 prelude anyways I’m trying to tune my fuel tables and here is the problem I am encountering. So I’ve got an aem wideband hooked up to my analog 0 input and it reads the same in my display gauge as the gauge does on my dash but when I am datalogging it’s populating all my fuel tables with a 17.70 reading when I know it’s at a 14.7 it reads 14.7 on the gauge and the display window but doesn’t read properly in my tables… I must have some setting wrong. Any idea what it could be? I’ve done some searching around and can’t find the answers.

Post your calibration as well as a datalog showing the issue.

please help this is so annoying and I have no idea whats going n

It appears to be running very rich in the areas datalogged. It also has a fairly high negative long term fuel trim and the short term trims are also pretty far out. This indicates that the Calibration you have posted is not what the datalog was made with.

Rather than use an analog input on the s300 I would recommend using the D10 input on the ECU.

I’ve used d14 d12 does the same thing… is there a way to assign the analog 0 to be the afr reading that s300 uses? Because my gauge reads exactly as the analog 0 says on display but my afr sensor window and tables are populating a different number

Do not use D14, as it cannot see the full voltage range. The analog inputs on the s300 cannot be used for closed loop or protections.
