Yep. Works nice for me as stated above. I might just need to extend the operating range for summer. Hopefully heads and cam in about a week. (Got postponed 7 days!!!!!)

What I am thinking might be a valuable addition to the next custom OS is to have the A0014 Open Loop IAT VE Multiplier Table have a range more closely related to real world temps. My IAT's generally are around 10°F above ambient and I am never near -20,30,40°C nor near 100,110,120,130,140°C. If we could have more values near 20-30°C I think that will help most of us be more spot on during those normal operating IAT area's.
I see through my logs in Open loop, the closer I am to colder IAT's the ritcher the A/F but then as the IAT's rise (in the same 20°C row) the mixture gets leaner. If there were more values for this table I could really hone A0014 in.
Something like below for example.

It will automatically interpolate dude.
So if its 1.0 at 20 and 1.1 at 30 it will be 1.05 at 25.
So Id not worry too much about the resolution myself.
Gotya, I will then just create a filter on the logs to filter out the inbetween temps to get the 100% correction factor for that temp and let the interpolation do its job.
has anyone setup a MAP to make this easier?
It would be similar to RAF maps but I cannot see what the column should be (Data = BEN, Row = IAT, Column = ??)
This is what I did, not saying its 100% right.
Anyone else feel free to correct.
It is a lot harder to change table axis in code than it is to add a table in to the code .Quote:

Set up a ben factor and IAT map and use that to correct the A0014 Open Loop IAT VE Multiplier Table.
My table is
0.911377
0.922607

Its pretty close
Your attachment isn't opening vette, says the zip file is corrupt
The original .zip I made opens fine, I downloaded the one that was uploaded to the forum saved to a new name and it didn't open.
I will upload again. Must be something with the upload to the forum or something. Too bad we can't just upload .maps
Ok that still didn't work,
Here you go a link to it hosted on my buddies website.
