Proform 850 dialing it in closer
Seems a lot more erratic.
That might be just the difference in AFR and time scales scales. Logworks might have automatically scaled the AFR different.
I see 10, 11 and 12 AFR on the axis of the 2 bbl launch but only 10 and 12 on the 4 bbl.
If you want to attempt a direct comparison, there is a bar like symbol at the top. More like a thin "I" Use that to select and copy a section of the 2 bbl log. Then overlay that onto the 4 bbl log. Move it around to so the start rpms of the 2nd gear shift line up (or whatever you want).
The software has a lot of powerful features to discover. :)
Rolling 2nt gear launch expanded.
Looks like i still have room to lean it out some more.70 front 80 rear with all of these bar graphs.
It does look that way. I don't know what your engine likes.
You can use this tool to show the AFRs and RPM at any point. It makes it easier to compare stuff.
What bother me more is the sloping.
Could be too much air in the main wells.
And also maybe too much main airbleed.
I'd look at the emulsion-holes and HSABs to see what is there. Then decide.
