Hey
Check out the attached *modified* logs from your pull. I break it up like this as it is easier to see which rpm windows are lean/rich and by how much. I added an 'offset' column that shows how far you are off from your target AFR at each data point (where positive values are rich, negative values are lean, and the values in blue are within .1 of the target).
If you take a look at time stamp 16.146-16.426 you are really lean right after you punch the throttle. When you see the "pump" value (which I have highlighted red) this signifies that your Async Gain feature was triggered and an extra pulse of fuel was sprayed to account for the rapid throttle change. As the car went extremely lean upon punching the throttle I would recommend changing the Async Gain in the predictable map corrections tab to 200% and then reducing the value if you are going overly rich upon punching it. I'd rather tune down from a rich condition anytime rather than tuning up from a lean condition. In this same tab I would also un-check the extra sensitive throttle box.
In the idle tab you are going to want to also un-check the "Extln 1/64th Elec Load" box and the "close idle on boost" box. Per Mark Gool of Adaptronic upon a review of my ECU file: "Can you also please untick the "Extin 1/64" and "Close idle on boost" options if you have them enabled? We do not use this on RX7s."
I'd still be interested in the source of that 4% trim that is showing up while in open loop above 0 PSI. You can email adaptronic and have them run your ECU file on the bench and they may be able to track down the source of the trim. I'd be careful about subtracting fuel from the map until you know where that is coming from.
Do you have a knock sensor? I noticed that your logs read 0 knock across the entire pull.
Are you running an ISC valve?
And what exactly are you doing with AUX 9-10-11?

AUX 9-10-11 are set up for anti-lag settings.
yes I have a knock sensor. its just reading zeros. it shows knock latter in the logs. like at 25 seconds or so.
I am running a ISC valve
well the changes I made between 1,9 and 2.0 im hoping that fixes the trim. about to go do the logs now.
