max setting just doesn't pull air from outside, once ac is on the max setting doesn't matter. Defrost setting tuses the compressor the sam as ac max or regular.gotchopsticks said:i hardly ever use a/c because of that. and if i do its only on the freeway, and i cruise at 65-70. which setting is better, max or regular? i heard max was more efficient, but which one uses more gas? what kind of tune would you recomend with the different settings? and are they switch on the fly? thanks for everyones help.

gotchopsticks said:how can you say that the tune wasnt affecting my milage when i took it off and now im getting close to 20mpg, driving harder than with the tune on. my tire pressure is fine, and i do need to clean my air filter, but i can clearly see the difference with stock configuration.

I have no doubt that you know a great deal about tuning . I think you don't understand or I worded it incorrectly. There are obviously still problems. I do not tune cars. I take it to someone, but know a little about what is changed. If a plug is not firing and you reduce the amout of fuel , there is less raw fuel going in.If the tune adds more fuel , even at WOT and the plug is not firing correctly, there will be more even more raw fuel dumped. Is this not correct. I don't know if this guy can look at a plug and tell if it looks like that plug is not firing or if he knows how to check for fire. $8.00 and change for a set of Autolites is pretty cheap and easy to do. It deff. won't hurt. I don't even know if most people can really calculate MPG. He removed the tune and things got better. Why isn't this possible? O2s very well may be a problem, hell, the tune with to much fuel and plugs fouled may have damaged the o2s. I I don't work on cars for a living but have worked on cars for 25 years. I get to see a lot of problems in a friends shopjstreet0204 said:Where are you getting this from? Do you have any knowledge about tuning to back this up?
I'm going to say this one more time. First most tunes out there have no changes as far as fuel goes except under WOT. And even then, The stock tune commands 12.0 in under in the last few cells of the stablized open loop fuel table. Now in order to make more power, do you think they would add fuel? No, they take it away and change it to around 13:1. If your tune is realy causing you bad mileage, then you may have a bad tune, BUT in general, this is not the norm and anyone saying other wise does not understand how the eec works.
