Proform 850 dialing it in closer
Yea!!!!!
Its interesting that in most cases the AFR drifted from leaner to richer then seemed to go steady. But the second gear to 6000 rpm on all 4 barrels (2nd screen capture) shows flat. H'mm. ???
Because this is a race car I'm not sure if what I'm going to write is a good idea. On a chassis dyno the procedure is to get the wheels and roller rolling. Then upshift to the gear it will be run, then put the throttle down. With an automatic this has to be done so as not to have it down shift. With a manual I think the only concern is to avoid tire slip/chripping on a shift. So I'm thinking if for testing purposes (no one else there) maybe change the procedure to emphasize either 2nd or 3rd without running out of room. ???? See what the other guys with more track and dyno time have say.
I've seen AFR lean in first and IMO that's something to do with the engine isn't seeing as much load. That's not really a good explanation as just an obesrvation of the relationship.
Software stuff
To expand the scales in logworks, use your mouse to click on the magnifier circled in blue.
Then move your mouse to horizontal scale and click on it.
Vertical scales can be expanded the same way.
Use the hand symbol to slide the scales up or down.
The little yellow symbol can be selected to put notes onto the log.
There is also a way to add information to the sessions. I think its by clicking on the sessions -> edit. Or maybe its by selecting the tab. To see the info, put the mouse over the tab.
As far as the noisy afr, I'm assuming that's reversion because there's no exhaust pipe after the collector.
