just stop by my shop and I'll show you how to make the wideband work.

 

ambient temps do not come into play for tuning on these cars. it's all IAT2's. MAF's calculate the mass of air flowing across it to determine how air is coming into the engine and then obviously using certain tables determining how much fuel to put in. By calculating mass it doesn't care what barometric pressure is.

 

i appreciate all the help...still reading as much as I can. honestly Idk if I will end up doing this. I want to learn. but this is my daily driver. so i'll see what happens

 

If you don't want to bite the bullet on the pro, you can always hook up with James on here. Your only about a 7.5 hour drive down. My cobalt is my daily as well and I am enjoying the 42-44 mpg on the highway. As the price of gas is going up, it is worth it.

 

UMMMMMM. Totally not true bro.. Without ambient temps we wouldnt know what the at1 would be, without the iat1 we wouldnt know what to compare to with iat2s. Without ambient we wouldnt know what * of coolness or hottness to tune for, less timing or more, for conservativness. SOOOO AMBIENT IS USED WITH ME LMAO!!!!!!

 

^^your the man, your the best, I suck. Any tuning questions should be directed to the genius above. I bow to you oh great one. This is the last post I will make.

 

IAT1 does not match actual ambient in most cases... at least not in my car

 

No i wasnt meaning to say ambient will match iat1s. Sorry for the confusion to anyone. I was just saying we need to see ambient temps. To basically see if one our system is working correctly. Most cars i tune are around 5* above ambient.

 

I wasnt tryin to be a dick.... Im not that type of person, i was just meaning i use ambient temps when i tune i compare all three iat1 and iat2s and ambients..

B][/B]

 

i would love to see a supercharged car seeing only 5* above ambient temperature....

 

lmao apparantly you are not reading...... If you notice i say my iat1s are usually 5-ect above ambients lmfao!!!!!!!!!

 

lolz sorry drunk and tired last night. That makes sense haha. Why even worry about that though when tuning.

 

Cuz it will tell me the basics of is my air filter clogged, is my maf working correctly with its iat1. Meaning is it dirty and ect. ....

 

i guess i can see where your coming from with that...
