Re: K-PRO V4 Wideband lambda problem - Running lean


AFCMD is the commanded AFR, the value above that (AF) should show what your wideband reads.
When you are not using a wideband as primary sensor the AF will show a static 14.7:1 just like yours are doing now.
I did take a look on the logs but not sure what the problem is here, maybe try and clear ...

Re: K-PRO V4 Wideband lambda problem - Running lean

Then I changed the CLOSED LOOP ADVANCED parameter "Open/closed loop target (KPRO 4) and ticked the "enable lambda look up table"

The logs show AF as 14.7:1 but the wideband was now reading rich at 11:1

With the ADVANCED CLOSED LOOP on factory settings

Data log attahed below shows a constant 14.7:1 AF ratio but the actual wideband lambda is reading lean at 18:1

Re: K-PRO V4 Wideband lambda problem - Running lean

I know its not a datalog but I took these screen grabs from the sensor list with the car running.

Capture 1 shows the AF as 14.7:1 and AFCMD as 14.7:1

However Capture 2 shows AN0 (which is the analog output from the AEM 30-4110 wideband) as 18.35:1

Re: K-PRO V4 Wideband lambda problem - Running lean

PRA AEM wideband LG 2.4.18.kal
Calibration should be attached.

I didnt take a data log but will do in the next few days.

Would you mind looking at the calibration to see if there is anything obvious that I have missed?

thank you for your help

Kind regards

K-PRO V4 Wideband lambda problem - Running lean

Hi.

PRA - K-PRO V4 (V4.3.5)

I am using a Wideband Lambda AEM 30-4110 with the analog output from the lambda wired to the Analogue input A0 Red wire on the K-pro 4.

I beleive I have enetered everything correctly on the calibration (standard factory PRA calibration) to use the external wideband ...
