AFR leaning out

[toanz28]

Hi
Recently I've encountered my AFR leaning out ( above 17:1 ). During those times, the car hesitates pretty bad, seems like
a misfire. This issue is intermittent, doesn't occur all the time. But I have been able to datalog some files as to when its
happening. Just wondering if i can get some tips as to where to look. either Ignition side or Fuel side.


Built H22 Turbo
p28 w/ s300
Stock ignition
RC750 cc injectors ( I think this may be the culprit )

Heres the calibration and some datalogs

What whideband are you using and why not run closed loop off the wideband signal?

Hi

I'm using PLX DM-6.

I have it installed as per the instructions. As for the settings in the parameters, That is how the tuner left it.

Any advice?

Try changing it to run closed loop off the wideband signal instead.
