      So what does everyone think of my MSQ?

      I might later, I deleted the "project" to allow me to load a HR msq.
      Tradition is the art of making the same mistake repeatedly, on purpose.

      Still no feedback about my MSQ?

      Well I did go out this weekend and try to do some data-logging but for some reason I only got a minute or so recorded. I'll go out tomorrow after work and try again.

      In the mean time here is a noisy video of my run.



      Enjoy.

      Nothing odd in the msq offhand other then the main fuel table looked very lean/low just off idle and until pretty high load/rpm. The 15.x afr targets in the middle of the table seemed a little odd as well. Datalog vs that msq might make some sense.

      OK thanks for the feedback.

      Here are what the tables used to look like before I had -RalleyTuned- try and help me out with the altitude issue a while back.

      I was able to go out and do a log today. Let me know what you think.

      Wow, glad to see you might be making some progress! I went out today and having set EGO Step and Authority, with the Target AFR table now set, did not make much difference.

      No progress here. I haven't had enough feedback to make any changes.

      Here is my feedback looking at the logs:

      You have no MAP range to speak of, which is common on ITBs. Make your lower kpa bin ~45-50 and spread the load bins out a ton more over that range. All of your low kpa should be handled by overrun fuel cut so you'll have to set that up. I would also change your afr targets a bit and get rid of anything leaner than 14.7:1 for now, the old AFR table with a tweaked MAP range would work better.

      OK great, thanks for the advice!

      Would it be possible to have you tweak my tables and MSQ to what you you were thinking?

      You have a lot more knowledge and experience in this area than I do.
