sorry for the ignorance, but, what is it??? Also what is barometric correction?? Is barometric pressure something that has to do with sea level?? I just realized that im going to have to the learn more about that box with e6k on it in my passenger side floor bored
Does the haltech manuel explain all this?? I dont have mine at this moment but I read bits and pieces from it and it was kinda confusing becuase it seem to be based on a piston engine..

Barometric pressure is the pressure of the air surrounding you. You have no doubt heard of a barometer, right? Barometric pressure plays a huge role in weather, and is a key factor in how an internal combustion engine operates.

The baro-correction in the E6K software provides a means for the computer to automatically adjust to changing barometric conditions. The primary usefulness of this feature is when the vehicle is operated throughout vast changes in altitude. Between the barometric and air temperature corrections, the ECU is able to automatically compensate for changes in air density.

A LOT of people who don’t understand how this works disable it. There is NO reason at all to fool with it. Just like the temp correction maps, if you don’t have an accurate means of measuring exactly what’s going on in the engine, you’re better off leaving it alone. Don’t fool with something that isn’t broken, etc.

Let me know if I’m not being clear enough. Its New Years, and my head still isn’t quite straight.

ok I understand. Is there a good site that explains how to tune the haltech??? Im not want to tune, I want be able make adjustments when nessesary. Also thanks, it was very helpful

Just remember, if you tuned it in a high altitude, you want to definately have it enabled, if you plan to go down to sea level, the relative density of air in high altitude is significantly less, so with no correction, going from a low altitude to a high altitude will essentially make your map too rich, and from high to low will make it too lean.

Tuning a Haltech is no different than tuning any other programmable ECU. There are some books available that will go a long ways toward helping you achieve your goal. BUT, nobody (including myself) will try to teach you from start to finish how to do it. Why? It's a learned skill, an art form of sorts. It's not easy, and being properly equipped for it will cost you some real money. That's not to say that you can't figure it out, because I'm certain you can. It'll just take some time to get the hang of it. You'll do fine if you don't rush things.

Whether you tune the car at high or low altitude, leave the baro correction enabled and DON'T MESS with the correction curve! Trust me on this one. . .

Yea, the change in air density over changes in altitude are well documented, in fact they've been standardized. So unless your engine needs significantly more or less fuel than "normal" for a given altitude change, my guess is that the base correction map is more than adequate.
