Here is the amended ve table that I was using last night. I made a mistake with the data log, and the file doesn't contain the test run that I thought it did. I'll try to get another one tonight and post it later.

Here is a datalog file using the ve table I posted earlier today. It shows the lean condition starting around 4000 RPM that seems to persist regardless how rich I make the ve table in that region.

I'm open to any and all suggestions.

Thanks.

Is there a Stimultor for the MicroSquirt controllers? If not, could I adapt the MegaSquirt Stimulator to work with a MicroSquirt? If I could set up my controller on the bench with a standard set of inputs and loads from the Stimulator, that might give me some clues that would get me closer to a solution.

Does this sound like a good idea? Are there more things I should be trying with the controller still in the car?

Bruce and I are at the Megasquirt Meeting. As soon as Bruce has time he will look at the traces. I haven't really seen any fueling problems in ages, so I'm not sure what to say. Give us some time to think about this. Also, please post your msq. The stim can be made to work with microsquirt, but you would have to work out the wiring.
