I got my car tuned in California where the air is a lil cooler and I'm now living in Arizona where it's like 3,000ft above sea level and it's a lil hotter here (air is thinner also). Just wanted to know if driving here in AZ hurt/effect my performance/engine? (ie. a/f ratio, running rich/lean, etc.)

 

say you were going from a mid summer to Miami Tune to mid winter in colorado... maybe....

im sure the performance would be diff due to the air, but im not sure how much a tune would be able to do....... but then again, i dont know, thats just where logical thinking took me....

 

you don't have a wideband? cause if you did, you could figure if you were running lean.

what was your a/f after tune in warmer climate?

ya, i figured the elevation would have something to do with it...but i wasnt sure if this would hurt my car--getting it tuned at sea level and driving it at 3,000ft above sea level everyday.

nah, i dont have a wideband...how much are those? I think my a/f was at about 14.1

if anything it would run a little richer since you are higher in elevation and its a TAD hotter. 14.1 is a little lean to make the best power, so based on what you are saying, you could actually be running around the correct afr at WOT.

widebands range from 300-600

i run a zeitronix zt2

would a car running lean smell, look, sound, feel, (taste) different? And what's your AFR?

 

running a little lean wont smell like anything. after an interstate pull during logging, it will smell like fuel after i let off, but thats about it. My afr is about 13:1 at WOT and 15.0 at part throttle.

what are you smelling?

 

Not smelling anything but fuel i'm burning at 8200rpm

 

Yes, it will affect the tune.

The PLX widebands go for about 315. I use them to tune every car that I do.

Let me know if you need one

how much do you sell them for? (H-T discount?)
and would it affect the tune to a point where it's noticable?

 

depends on how much of a climate and elevation change you went through. But yes, given certain circumstances, it can be noticeable.

3000ft elevation and 5-10 degrees hotter

 

in cali, you were at sea level?

 

close, very close....

 

Ok well, I have a house in Colorado Springs (suburb) which is at 7800ft, then Cleveland Ohio which is 200ft? so im dropping 1¼ MILE, and trust me I noticed the difference on my NA setup but I have the same question you do so any answers would help ALOT
