Well if you look at it in 2d line form you can see that it is actually sloping or interpolating.

I was looking at the stock settings and figure it must interpolate otherwise it would be too drastic a change as the ECT passed through different ranges.
In other news, I checked low fan operation and noticed maybe +.05 g/s stit and high fan was about +.25 which seems too high. So, i'm setting fan 1 & 2 to .15 g/s and .35 g/s, respectively.
I got some strange changes with AC that are probably more influenced by RPM and Timing look up tables.

I tried adjusting this and have a few questions. From a dead cold start, I monitored my STIT and LTIT. My LTIT after I adjusted the RAF table is now about 0 from cold start to normal operating temps, but from 32* my STIT is 3.0 and gradually goes down to 0 at op. temp. Is this correct?? What do you do with the IAC Park Postion Table?
Here is what my RAF table looks like now.

Seems that your base running airflow is dialed in at higher ECT but about 3 too low at lower ECT. May not be worth the effort to tune at lower temperature.Originally Posted by Black02SS
Create a scatter graph LTIT+STIT vs ECT. This will give you a visual indication of idle trims for 20, 40, 60, 80, 100C. (SI)

I too am am curious on how to set the park table. I know how to do it using the MAF aiflow PID's however, I have not dialed in my new MAF table yet, and therefore, anything that it is reporting is not acurrate enough to work with. I wonder if it can be done using the dynamic cylinder air insted. I'm going to see if I can come up with something. BTW does anyone even know what the park table is used for?
I was wondering if we took the "Idle Desired Airflow Pid" and transfered that information to the IAC Park table how it would work out. I am going to try this maybe today or tomorrow and see what happens. Any ideas??
OK, I tried it this evening, and I don't understand a few things. The engine had been off for about 5 hours. I logged both STIT, ECT, and both LTIT's.
1. STIT starts out around 0.5, rises quickly to 0.62 in 1 second. ECT=106
2. STIT falls to .21 over the course of the next 40 seconds. ECT =113
3. While stopping at lights, the STIT:
a) starts at 0.09 and drops to 0.04 in 8 seconds, ECT=~160
b) starts at 0.04 and drops to 0.01 in 2 seconds, ECT=~174
c) starts at 0.04 and drops to 0.03 in 2 seconds, ECT=181
d) starts at 0.03, rises to 0.04, then drops to 0.01in 7 seconds, ECT=180
e) starts at -0.01 and drops to -0.06
4. LTIT's never stray from zero.
Why did my LTIT's stay at zero the entire log?
Would I take the average (0.31) of all those values at 106-113*F, multiply it by 7.575 (=2.34), and add it to my 104* in-gear cell?
It would be easier for you to scan and edit in imperical instead of converting to standard units of measurement.
If the LTIT stay zero then your settings are probably good. Adding 2.34 at 104 may not affect idle since you dont have data at lower temperatures. If the above airflow is in g/s then its good already at that temp range. I had more variability at cooler temperatures 50-60F.

All logged units were imperial, and as are my defaults. Which sensor(s) contribute to the calculation of the STIT & LTIT's?
I guess I'll need to let the car sit overnight. Maybe the ambient temp will get into the 60's to check the lower cells.
I just downloaded the current version. My log from last night had a single incorrect row where the LTIT was -1.4 and the ECT was -40, surrounded by ECT's of 124.
I was wondering why it made such a huge compensation at -40*
I don't really see where any of us are going to see a temp of-40 so I made a change and had it delete any rows of data when the colant was -40. It is on the server for DL.
I received an error message in the spreadsheet with my latest log. I'll forward you the calibration sheet with my data included.
Fixed. I added a data integrity feature and it calls for RPM as well. I have added that to the sheet. It still works, but you just need to log RPM as well now.Sorry about that.
