Stumbles

I 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.

In the handheld definition section here.  There is an area called Accel.  Read up on this.  Watch your AFR when stumble occurs.  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.

Thanks for your help. My problem is it goes rich down to 10 afr

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.

 

Dial on the Accel first.  Once you are happy with that then dial in Fast Accel.  This is for quick throttle changes.  You may not need to adjust Fast Accel.

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