Opinion on my log after SAFC tuning

delta448 · Mar 24, 2009

How certain are you of the O2 sensor data? Looks suspect that it held only two exact voltages. Any way you could post a log from another datalogger to be sure?

If those are accurate, I would think that you could gain a little from leaning out slightly. Timing is right about where I'd want it, so I wouldn't lean out too much.

if that knock logging is working now, I would go leaner!

lean it out until you see 3-5knocks.. than softly richen up until knock is "gone" (gone means 0-3 units)
Thats they way I tuned for gasonline.

I'm sure the o2 is reading correct, at WOT the o2 is supposed to hold a steady voltage. I think I can go leaner as well.

if that knock logging is working now, I would go leaner

I'm not 100% that the Knock log is accurate, but if it is, it would be alot easier to tune with!! Still working on that. I logged with Ceddys mhi logger, but haven't figured out how to look at the actual log yet.

In Ceddys post about his new logger he explained to me how to set up EvoScan to read knock depending on which year you have. Maybe it will help you.
