    Had a few mins spare time this morning so i tried zeroing out that table and smoothing out the ve table. Still will not maintain. Starts around 14.0 and drops to about 12.2 at the end of the log. newest idle.efi here is the latest log

    Sorry, I've been running a bit (a lot) behind.

    Please post the tune file that produced this log.

    I looked at your log file, and I could not see anything in the tune file that would directly cause what you're seeing.

    Possible cause: are the injector tables correct (B3701, B4003, B4004, B4005, B4006, B9021)...?

    Try putting negative values in B4005 (say -1.5 ms) and take another log.

    I am fairly sure the injector data is correct as it is from a known good tune that isn't having this problem. I will give the -1.5 a try. Hopefully that helps cause I am totally out of ideas

    Tried the new tune this morning it wouldnt run at -1.5. Finally got it down to a -.4 and it fires right up at 15.6 afr but still the same thing once warm its in the lower 13s. Do i need to add airflow above 150*f or is this just something i have to live with running open loop speed density
