I will have our software engineers look into why the AF reading is not changing form 14.7 as I believe that is the issue.


Hondata,

Was this issue ever resolved? I have a PRB Kprov4 that is adding fuel if using the same AEM 30-4110 as an external wideband in closed loop operation.

Thanks ...

THE PROBLEM HAS BEEN RESOLVED.

I wanted to make sure the KPRO was not corrupt itself, so I reached out to a local RSX Type S owner who had a CAI and exhaust. Stock O2 sensor. plugged it in with a stock K20A2 map and long behold the car ran as it should on a stock sensor. the S trim was acting as ...

Yeah as far as I know, my friend and the tuner all the right boxes are checked off.. so I’m lost at this point. I would have to take another log the other ones I have are too long to upload to this thread.

no your are right its not taking away and adding to much for no reason when its already rich. its not bringing it up to 14.7 AFR
this is the same calibration as the datalog. all the datalogs i.ve been sending to the tuner have been the same. all adding fuel even when he scaled the fuel back it was ...

the AF and target AF change, its just the S. trim is not adjust accordingly. its not taking away fuel to meet 14.7 but rather adding when its already very rich.

yes the 3 original calibrations that were sent to me all had the target tables enabled and had the same issues. this time around the tuner sent me a fresh calibration with the WOT 0.85 selected and the same issue is present.

removed the voltage offset no change. I beleive the offset is just to match up the gauge reading and the kmanager reading from the gauge.
