Question on Idle Speed vs Temp Table
I have a question concerning the Idle Speed vs Coolant Temp table in the ARAP Bin. Is the idle speed in the table with the trans in Park/Neutral or with the trans in Drive and vehicle stopped/not moving?
I have a 350 with modifed TPI running ARAP bin. I'm not having any issues, but I was curious about this table.

Re: Question on Idle Speed vs Temp Table
I have seen the P/N rpm adder table. So, the Idle Speed vs Coolant Temp table is with the trans in Drive. In P/N, it adds rpm via the P/N adder table. My TPI motor idles around 900 rpm with the trans in park. I just removed my BBK 52mm throttle body and installed the polished throttle body I got from Dr. Injector a few years ago. I still need to adjust min air. I was hoping to not have to do that, but at idle my IAC counts were close to 60. From what I have read on these forums, 60 counts at idle is way too high, so I need to open the throttle blades more.
