How Does Tuning Work???

[onewheelmik]

I'm just wondering how tuning works on a vehicle with only basic bolt ons? If you don't have a timing changer you can't get that done and without a blower theres nothin else to adjust...right? Maybe i just don't know how the tuners work on a stang. So how is a stang with all bolt ons and no timing adjuster going to build higher HP on a dyno with nothing to adjust??

You buy a SCT chip form our site sponsor VMP !!! the new chip overrides your current computer factory setting .You can adjust timing,fuel/air ratio, run a 87tune ,93 tune shift point Etc. I sure one our expert will jump in with more info

your AFR can be adjusted as well as many many many other parameters. Air/Fuel Ratio = AFR

well on mildly modded naturally aspirated setups, youll want to try to find the max amount of timing advance with the leanest fuel ratio. what a tuner will do is he will add timing and take out fuel till he finds the "Edge" of the tune, the point at which exhaust gases get too hot (leaner burns hotter and melts pistons) or if the car has a knock sensor, you get predetonation/knock, in which case youve found the edge. the tuner will then back away and add his safety margin to compensate for atmospheric conditions.

you can do alot of things, including changing your fuel map and fuel timings (like for wide LSA cams) adjust MAF transfers, change spark timing across the board, play with injector loads.. and alot of stuff that I didn't even cosider to list.

all this stuff is somewhat optimized from the factory of coarse, gaining anything from changes really only comes to play when the car has been modified.. which is more than just cold air and exhaust, that is provided it isn't a 03+cobra
