I’ve recently installed the Ballenger AFR500 with the calibration grade sensor. The wideband seems to be very responsive and accurate when tuning WOT. The only weird thing I’ve run in to is the car likes to idle in the low 14 AFR area.
I have recalibrated the NTK calibration sensor twice to make sure it is reading accurately, and the sensor is logging in DSMLink as it should (Test values in warmup are spot on and display matches DSMLink as well).
I swapped in a new Bosch front O2 (Died after an hour) but it read the same as the old sensor. The car will cruise around 14.7 so I know closed loop is still targeting 14.7 there.
Anyone have this issue with a stock front o2 sensor causing the car to idle rich/lean at idle? If I simulate using the Ballenger sensor, it will idle around 14.7 but its not as smooth/fluid as the OEM front O2.
I attached a log of the vehicle idling with the front O2 and a log of it idling with the front O2 being simulated. This ECU was just socketed and checked out by ECMLink.
Any tips would be greatly appreciated!
