Hi all,

I am trying to setup an AFR ERROR parameter on HPtuners for an LNF.

Currently I have it set up as [6005.238] - [6160.238]
Both WB EQ ratio and Equivalence Ratio commanded are enabled on the channels.

For the graph I have to
Column Axis = Absolute Load
Row Axis = Engine Speed Sensor
(The axis values match the Maf correction table)

Decimal = 3

Then setup another graph so it mimics it exactly but for STFT+LTFT Math parameter

Is this the correct way to set it up?

If so I take it that after a log these are added over to the Maf correction table?

I am trying to troubleshoot an error where the STFT will just default to 0 and the Wideband reading goes out of control. The CMD lambda matches the PE table but the fuel goes way lean or way rich.

It happens randomly and it happens with or without the maf. Replaced the maf as well.

How many miles are on the car? Might be that your wideband sensor is going bad. Tends to happen after a few years.

The wires to my sensors rubbed through cause the Fuel trims to stop working.
