Some logs for you input.

http://tinyurl.com/yslfas This one is: Started recording, started warm engine, couple throttle bumps to low idle, then drop in to gear.

http://tinyurl.com/27h2wb This one is: 10 mph rolling start, hit it (throttle), shift from 1st to 2nd, let off before I got the law looking my way.

This logging is a lot of fun. Setting it up fun too.

Looks like you have a good 12.5-12.8:1 mix on the WOT pull. Will look more later. Overall, looks like you're in decent shape.

Ya the main AFR seems good, its the tip in and off idle slammed to the floor major hesitation thats the prblem. I realize the AFR will allways go a bit lean from idle to, well not idle. Just tring to get an idea from looking at the charts how to correct the problem without just tring every combination untill it looks good and feels good.

When I looked at it I thought that big lean jump was like a electrical spike, but your saying it is going that lean?


Do some more cruizing and steady state logs, but post the whole log and not just pics. I can run the logs as I guess others can also.


Have you tried your sensor in each header to see how much they differ from each other? ALthough thats going to come into play more so for WOT.
