Default Coolant Related Air Density Settings

What are you guys running for the coolant related air density settings?
On the main page I have
50 105
55 110
60 115
65 119
70 124
75 129
102 150

My real questions comes down to whats under your settings. I have
Air denseity Correction: Corrected
Correction based on: IAT Corrected
Start to reduce at : 2000
End Ccorrection at: 3000

I got those from the diyautotunes mspnp maps and when I applied those setting it really made my car run rich. I am wondering if I should undo them or leave them and tune from there. I looked at a few msq posted on here and no one had anything set for those so I am curious as to how I should procede.

I would suggest disabling CLT Related Air Density... If you use our entire map then those settings should be fine and you could leave it enabled, if you're trying to just pull these settings from our map then I'm thinking you'd be better off without them.

FWIW it's disabled on the MSPNP MM9495 map. I'd do the same on the MM9093 map though I'll need to retune the VE table to do so...

Thanks Jerry for the reply, I was just trying diffrent things and that was something i noticed you had on in the msq I had got form you. I will turn it off tommorow and go about tuning as normal.

I use the following settings:

10 96
20 100
30 105
40 109
50 114
60 118
80 128


That's with the same settings as you have i.e. IAT based correction.

I can't state enough how much of a difference these settings made to the drivability of my car!

Previously when hot starting the car ran *really* lean and the idle was way too low (MS not controlling idle currently) with these settings it's 95% stock now. It's not hard work driving the car from a hotstart/heatsoaked anymore.

Also bear in mind I'm supercharged so my ambient intake temps are much higher than a stock cars.

The hot starts were actually why I turned the settings on. I have seen IAT temps as high as 150F when driving around tound. Keep in mind this is a stock intake on a black car so there is massive amounts of heat soak. With the high IAT temps it will sometimes make my car run lean and the idle becomes very rough and movece all over the place. So I was curious if this would help fix that any.

It definately will fix it, my temps are in DegC so you'll have to convert those

you may need to fine tune it further, but I've a feeling it'll be lots better straight off from using mine

I found the linke for the explanation of how exactly this all works but after reading I still am confused about it.
http://www.msextra.com/manuals/MS_Ex...l.htm#cooldens

The description of what it does sounds exactly what is happening with my IAT temps so I am assuming I should figure this out. I am trying out richys settings but I am still unsre how exactly this all works. If any one could get me a slightly better explanation it would be greatly welcomed.
