Many Import Performance Tuners begin with searching the right information. If this is what you are looking for, you’re in the right place.
It is simply to classify the majority import as they are under construction abroad, however import is defined not only as foreign vehicles, and also sports compact cars of the American manufacturers.
Adjustment for the majority of people is trying to squeeze out all possible a few horse powers from a vehicle, and for some of the least informed, it also means to endow durability and reliability of the engine (that in it good additional 5whp when they appear 45K miles earlier).
Import tuning is no different than building of old times. Updating of the fuel system to support changes is extremely important. The majority of subjects as S-AFC or electronic operate by change of values of gages occurs in the computer to increase or reduce a debt an injector. Though it works in practice if you want to add 10 % on board to make your car, leaving that on 0, and increasing the pressure of fuel is more safe way to do things, and also allows the computer to work, as it was primary.
But back to the pressure in the fuel system. After a few runs with your car, look at its full air / fuel value for the degree of your test. If you change something to increase the volumetric efficiency of the engine, the engine will be compact (a combustible mixture is higher than before), then when you started. If you need less overall in the ratio, a simple adjustment of fuel pressure can fix it. At cruising speed, air / fuel must always be 14.7:1, the entire car at full load should be around 13.5:1, and forced induction vehicle at full load should be directed to 11.2-11.9:1. The higher the number, the more compact (less fuel) the vehicle is.
Some machines will not show changes, but it is necessary further tuning by means of short-and long strips of fuel. Nowadays most cars will let these values go + / - 25%, and in the ideal case, the pressure in the fuel system should be adjusted so that they are all + / - 5% so that the maps are open to vehicle if they are necessary.
Run the vehicle several times with an obd-2 data logger on board. Look on fuel balancing of values and see, where they have a rest. If a vehicle adds much fuel scraps, then appendix of some more pounds on square inch of pressure of fuel can essentially reduce this number. Besides, if you see it having pulled fuel balancing, fuel pressure decrease will be compensated to establish it. It is very important, that the vehicle is a full spectrum at entering of updating for various conditions, such as the weather, temperatures and heights.
