I suppose I can hold off making changes. I got a little antsy last week, I've been doing my best not to interfere so I don't throw off what you're testing, this system has enough variables in it without me mucking around.
On that last log, I tried to get a small blip and large blip for headlights off and on. I tried to get four identical blips on this log, the first two without headlights and the last two with headlights. It looks like the 2nd and 3rd blips are pretty close, the 2nd w/o headlights and the 3rd with. Idle is much more stable overall, although lots of turning in a parking garage with headlights on killed the engine (didn't get a log of that, but I can if you'd like). Power steering seems to be tough for the engine/ECU to recover from, other idle situations seem pretty darn good!
Below are my highlights from the log. ECT hit 80C at frame 271, overall things seem to have improved. I floored it in sixth gear and watched my AFR at one point, it was a bit richer than the commanded AFR, 11.76:1 vs 12.53:1 around frame 1420. This was at relatively low RPM for PE, this seemed note worthy to me since fueling seems to be pretty important. There are similar results around frame 1630.
Bucking during deceleration:
Frames 1582-1595
Frames 1760-1863 (low amplitude then higher amplitude)
Frames 1991-2027
Frames 3653-3686
Frames 4180-4220
Frames 4306-4368
Frames 7720-7791
Surging/bucking during cruising:
Frames 2587-2630
Frames 2940-3103
Frames 4554-4577
Frames 5017-5249
Frames 5464-5538
Frames 7802-7915
Frames 8016-8185 (minor then major bucking)
Throttle blip 1, no headlights: Frames 12015-12053
Throttle blip 2, no headlights: Frames 12058-12093
Throttle blip 3, headlights: Frames 12097-12138
Throttle blip 4, headlights: Frames 12143-12180
Let me know what you think, if there are specific tests/logs I can do I'm happy to do them! Thank you again for helping out!
