I will add this to my winter list as something to research. Now with ME, is it possible to calibrate a separate IAT sensor? My limitation is with the 2006 version of ATR. I do not have an IAT calibration table. Unless there is another IAT sensor that exactly matches the OEM sensor in calibration I am stuck using a second MAF to move it post turbo.
Thank you for the advice!

1/Run lower boost
2/Buy ME for as it has calibration for the IAT sensor
3/Fit a stock Maf sensor post turbo and seperate the wires out

You have several options really .
1/Run lower boost
2/Buy ME for as it has calibration for the IAT sensor
3/Fit a stock Maf sensor post turbo and seperate the wires out

2/Likely my best option, as this will also let me log an external WB, I hope
3/ My second option, I just don't like hacking the wires and soldering direct to the MAF. Have you seen a plug I could mate up to the second MAF, besides a spare harness?
4/ I have read that thread and I don't believe it is an option for me because I have an '06 and the '06 ATR does not have an IAT calibration table.

2/ perhaps yes - but it does have more bugs than the AP
3/ I believe you can buy the exact plug you need quite easily .
4/That was the beauty of that mod - no re calibration was necessary. I have been running that sensor for 4 years . It works just fine . Perhaps not as quick acting as others but good enough to do the job.

Ok, so I will go back and re-read your thread for option 4. If it didn't require recalibration that would actually be pretty sweet.
So on stock apex seals you think I am pushing too much?
Any links for the connector? I am coming up empty

*7-8 psi is the safe limit on a properly tuned car with stock apexs . A major detonation at this level will still kill the engine but is way less likely to happen.
*10psi is when it can all go **** up at the slightest issue . If you think you wont have an issue .............. you are an extreme optimist .
Connector - pretty sure someone i know sent me a link . Will ask again . Otherwise there is always the option of going to a wrecker .

Either an optimist or just plain nuts check out the AFR at the top end of this log...
Would love to get a link for that connector! Local wrecking yard wants several hundred for the harness.

Yeah ...... too lean .
I see that was before you changed the maf scaling - yet calc load still only goes to 190 and ambient is still low .
Think that IAT relocation will help with that .... a lot !
What is your elevation ? Could be a factor as well .

gregs! update us on your new set-up

brettus what kind of intake temps do you see with yours post turbo?
with having a higher temp observed, that decreased the calc load further.
I have thought about doing this mod but figured the temps would be too high and further complicate the tune. hence my first Q

what are you doing to "smooth it out"? adding fuel?

Sorry, missed your q about elevation: about 2000.

IAT of 53.5deg.F = 1.05
Atm press at 2000ft = 92.8kPa = 0.92
1.05 x 0.92 x 200 = 193
Slash's actual max calc load is 190 so it doesn't line up exactly but there could be other factors involved . EG weather effect on atm. press , elevation was actually 2400ft
I would be really interested to know how he got earlier numbers over 200 . What was the elevation/temp and if the IAT and press. compensation maps were stock or not .

Well, since g/s is one of the factors in calculating load then my artificially high MAF scale would have led to a higher calculated load. At least that was my train of though.
Actually, max calculated load in the last log was 191.3, so while still not exactly 193, it seems close enough to make sense with the assumptions that other factors would cause this to deviate slightly, no?
Oh, and I made that log near the airport, which has a reported elevation of 2,376 feet.

Haha, posting at the same time! Oh and IAT and Baro comp tables are stock on the recent logs, but were not stock when MAF was not stock and calc load was up over 200%.
