ha.. i meant "Drove it a bit" sry...

and thanks for the input, I will call them today.

 

my utec wont seem to keep a tune... well thats how my tuner explained to me.. i know he knows what he is doin... says either rich as hell at idle or too lean over 4700rpm.. we are stumped... 1st had a bad utec since got a new 1 and still same... anyone got any clues?

 

Well, that's not enough information to give much advice. However, you can tune every 250 rpms, so their is no reason why you wouldn't be able to tune idle and upper RPM's differently.

Did you guys install it correctly by hooking up the ground wire? Is he updating the correct map and setting the map switch to the right one?

 

i dont know, ill have to ask him all this tomorrow.... i dont doubt his knowledge and i today was thinking it has to be something stupid like a ground wire or something along those lines

 

can someone help me with the utec air temp correction spreadsheet from the turboxs site?

What all do I need to change to calculate my corrections?

Is it Degrees C only in cell A5?

 

Car wouldnt run this morning had to switch to map 0.
I'm gonna try to load these settings tonight.
Here is what i have from the UTEC sheet:

Deg C (Day of Tune): 100

<1 -5 1.32 39%
1-10deg 5 1.27 34%
11-20deg 15 1.23 29%
21-30deg 25 1.18 25%
31-40deg 35 1.15 21%
41-50deg 45 1.11 17%
>50deg 55 1.08 14%


Can someone tell me if this looks correct?

Its about 40-50 in the morning and thats where im having the trouble

 

what was the temp when you had your tune? the spreadsheet is not really accurate so you will need to do some logging when the temp changes.

 

100 degrees C

 

so you had your car tuned at 100*C = 212*F?

units own you

 

/\ lol...

I have a turbo so my compensation is different but 34% is huge! I'm tuned around mid 30C and my correction on <1C is just 14%, and 1C-10C is about 7%.

 

werd, units definitely own me

 

OK so i used the correct temperature this time
100 F = 37.77 C

And here are the corrections:
<1 -5 1.32 16%
1-10deg 5 1.27 12%
11-20deg 15 1.23 8%
21-30deg 25 1.18 4%
31-40deg 35 1.15 1%
41-50deg 45 1.11 -2%
>50deg 55 1.08 -5%

Where should I go to get the Density Standard info for the date of tune?
I tried National Weather Service but no luck

Edit: nvm I see that it is calulated with some constants and my temp at day of tune

 

You're NA so it may not be a big deal but with Turbo/SC, you dont base your numbers on the Ambient Temp. You base it on the IAT temp and make adjustment accordingly. For example, ambient was around low 70's F (low 20's Celsius) when I did my tune but my IAT on load was about 35C (95 F) hence my 31-40 is 0%.

 

good to know, but I'm just using estimates for now.
I'm sure its better then being completely empty.

I've been running on map 0 for a few days since I was having issues in the cold.

 

exactly! YOU NEED TO CHECK THE IATs to use this temp compensation correctly. the closer you are toward the middle of the 21-30 range or the 31-40 range (ex. 25C or 35C), the better off your corrections will be when you plug values into the excel program.
