decrease ecu sensitivity to MAF/NBO2
Is there anything that will decrease the degree of MFI response to input at idle?
Using some agressive cams, everything pinned down except idle, it overcompensates going way too lean to missfire, then over rich in a vicious osccillating nightmare. Both open and closed loop. In closed loop for 1v -0.1v NBO2, the psice of crap ecu responds with 1.4 - 2.4 IDC respectively. If there is just a way to keep the IDC result in a 1.6 - 1.8 IDC window of operation for the respective NBO2 signal my idle would be good to go. Cruise is smooth.
Is there such a hacked table available for nonpatched rom (96420007)?

If you can figure out what Maf HZ the car bounces at during idle you could clamp it down with a combo of scaling and smoothing.

+1 on the MAF Hz as you have to ensure you are not hovering on the MAF Hz crossover from low and mid. If this is the case, I recommend raising the crossover point slightly.

This is the what the table looks like in my 88590015 rom. I searched briefly but didn't find it for your rom, but if you dig a bit deeper than I did you may be able to find it.
<table name="Closed Loop - LT Trim Control Ranges" category="Advanced Fuel Control" address="3021" type="2D" level="1" scaling="LT Trim Hz">
<table name="Conditions" type="Static Y Axis" elements="4">
<data>Low -> Mid</data>
<data>Mid -> Low</data>
<data>Mid -> High</data>
<data>High -> Mid</data>
</table>

time for v7 then, I think I have one of his first patchs from 2007
my rom is a 20008/20007 dynoflash mutant so that means I might have to jump to 20011 before I fully convert, right?
I might also be covered for donation as well since I was so happy from 07/08 for my original patch
