Cfol @ 14.6:1, Wb @ 19:1??

[Chalky]

I have been playing with my VE table. Car has been idling rougher than I felt was reasonable for cam/heads.

Car is in OL/SD and after 1st pass today in VE table using BEN results, I noticed car was stillc alling for fuel. I then noticed CFOL was right where it should be but AFR from WB was showing roughly 19:1.

Sound like an air leak to you?

Sounds more like a wide band O2 problem. If you're commanding 14.6 AFR and the wide band is reporting 19:1, that would be one hell of an air leak-- unless the leak is in the exhaust system at, or just in front of the wide band sensor.

Is it possible an injector isn't firing?

The car's idle is so bad, it almost feels like a plug or inj acting up at idle. Car pulls hard once I am under way.

I ended up starting from scratch again on my VE tune. I went back to all factory settinsgs except for injectors. Idle is still suspect but at least I have fewer variables. I have a stumble off idle now and steady state cruise @ 1500+/- is still not smooth. Going to bump up TF and play with decay in TC. When competing VE log, CFOL and WB02 were closer. WB was showing 15-16 but VE was also adding fuel so WB might be OK.

Is the misfire test worth doing in EFILive? It does feel like at 875-900 idle, car engine acts like a slight misfire.

ALmost forgot, but when completing RAFIG, correction is constantly moving a lot. E.G.:

32C 14.138
44C 13.144
56C 10.907????
68C 11.780
80C 11.573
92C 11.072

Cell counts were all over 300+ when I did RAFIG.

Try what I sent ya and let me know how it works out. The RAFIG shouldn't jump around as much with mine.

Also, try to capture the average RAFIG for the temp in the Desired Idle Airflow table and ignore the spots inbetween. It'll help dial it in a little closer.
