Dashpot was the problem. For some reason I messed with the higher rows and didn’t know what I was doing. I put it back to original and all is good now.

Around town everything seems ok but when at freeway speeds DESMAF is at .22 and acts like cruise control not letting the RPM come down. DESMAF doesn't come down until after coming to a stop. Is there anything with ISC that relates to MPH?

I figured it out. I was adjusting the ISC multiplier the wrong way. It wanted more but I kept taking it out.

Where do I look to find out what's causing the desmaf to add 74%? I've read the writeups over and over and cant figure this one out.

The ISCDTY is going to 100% immediately after startup and stays there for 5 seconds then starts to come done. There must be a table that I'm missing. Attached is a screenshot of FN1861 and the dashboard.

SPK_DSDRPM is showing 1328 but actual RPM is almost 1900. Here's a log of 2nd startup.

I cant figure out what is causing a high idle immediately after startup. It lasts 5-10 seconds and revs to 2000RPM then settles into a nice RPM. I have lowered FN1861 considerably but it doesn't seem to effect the 0-5 seconds after startup. Temperature doesn't have an effect. Even when hot it still revs to 2000 for 5 seconds before settling into a normal RPM. What parameter is causing this? I am running the latest A9L2. I attached my BIN if anyone wants to take a look.

A simple search found me the answer. Its been renamed to DESMAF_PID_N

Its been a while since I've messed around with my tune. There's been a bunch of updates to the A9L2 so I'm starting fresh. I downloaded the new Bin, ADX, and XDF files. I remember from before IPSIBR was on the dashboard to help dial in the throttle screw. Has this been changed? Is it now ISCDC?
