Stumbles
Quote from ta1968 on March 20, 2019, 1:17 pmI cant get rid of stumble. From dead stop punch little hard stumbles
Even when I roll into what every speed im going same thing stumbles.
Changed temp sensor updated software I changed o2 sensor also good there
I have cam set at two. The only thing I haven done yet is shield blue wire as others have said.
Here are spec's on my motor and a 30 second data log.

If AFR goes rich then immediately goes lean. You have to much Accel causing a rich condition and a stumble. If it does the opposite, then you don't have enough Accel. Adjust in increments of 10. The temp ranges are coolant temp range.
Adjust Accel first. Fast Accel should be adjusted last and only for full throttle quick throttle movement.

I'm a little confused do I start with all fast accel temp ranges? Or is there a spot where there is just fast accel, if so where do I find it.
Did my link wrk for my data log. If so how did it look to you.

Your datalog said it didn't exist. No biggie. Not necessary in this situation.
