I never logged with the AFR gauge input into the data log. I asked the person tuning how to do so as if memory serves me, my AEM gauge has an output for do that. He informed me that people usually delete the EGR and use that portion of the data stream. I need my EGR so I asked about eliminating the EGR diagnostic (the temp sensor on the EGR valve). In so many words he just told me it was more complicated than I think. Which may be true.

I think he just tuned by watching the BLM. And I think he got it done pretty good that way as the AFR gauge would be around 14.7 at idle and part throttle cruising. But as I mentioned in previous post, that was done during the valve train failing. Valve train fixed now. Running lean now and I need to fix that.
