Idle tuning - question/advice

Are the injectors new? Maybe you simply got a bad set? It just sounds like so much adjustment when as you said you have done many others before. I ended up having 2 of the 4 injectors flow different from the good 2 These were brand new and after pulling my hair out I finally got them flow tested and one way off and the other was just off a little . I swapped injectors and life is grand.
Good Luck

The Idle stability control is this.....
<table name="Idle Stability Timing Control" category="Timing" address="174e" type="2D" level="2" scaling="uint16">
<table name="Settings" type="Static X Axis" elements="3">
<data>Sensitivity</data>
<data>Timing Limit</data>
<data>Untested</data>
</table>
</table>
Add this to your 94170015 xml. It will allow you to increase the sensitivity for idle. Helps to keep the car from hunting at idle. Stock value is 128....raise it to about 146.
Second question....I didn't mean raise the Hz values, I meant raise the scaling values. Sorry about that.
Third question.....Yes you should start to see some LTFT adjustments.

I would try it and see if the map looks right. I did for my 96420008 and everything looks right in the tables. I havent been able to test it cause my car is at Buschur right now.

Just a quick update:
I finally got the car idling well and the trims were reading. What I did was -
This cured all my issues I was having with the car.
Thanks for the input and suggestions guys
I finally got the car idling well and the trims were reading. What I did was -
- Backed out the MAF screw all the way until it was flush inside
- Raised the idle sensitivity as suggested earlier
- Raised the idle timing to 10
- Adjusted the MAF scaling at idle as well as cruise and scaled the remainer of the graph
- Raised the idle to 1075ish
- Set the cam gears at +1 exhaust, +3 intake
- Used mrfred's MAT patch instead of Teprha's MAT patch in v7 ROM
This cured all my issues I was having with the car.

Glad we could get you on the right track. How does the car idle with the AC on?

The car idles great with AC after a few adjustments I made, although the owner just t-boned a telephone pole so its out of commission now for a while
