O2/Knock Sensor Question!!

[omgosh]

Ah, you're right about the sensors reading differently. I forgot the skinny sensor does indeed show less voltage than the usdm one. So yeah, Id say the o2 readings actually do make sense on the second log. My bad. You will be able to observe the o2 cycling at idle during closed loop. During wide open you will still get a reading but its not really useful for comparing to anything other than itself.

As for your timing curve; Can you not monitor knock? It looks like a stock timing curve to me. Id say the knock sensor trick worked. Could be a little smoother but not bad. It looks alot better than your friends log. The timing is supposed to drop to about 8-10* during peak torque then steadily climb to ~20* by redline.. If you look at your log from 5000-6000 rpms the timing goes from 14* to 19*. Your friends only goes from 10* to 14* during the 5-6k segment. Also his TPS is not right. lol

You really should get the knock sensor working though. Its there for a reason IMO.

And for the o2, just bust out the multimeter and start probing wires. GL
