hi/mid/low and ve questions

Alright this may sound a little basic but Im wondering if the hi,low and mid throttle settings are mainly for partial throttle fueling while you can also change the values on the ve table to adjust fueling also reading from another post.

Now would it be better to adjust the ve table settings for wot or keep the afr tracking enabled. Or by adjusting the ve table the hi, etc tables would be thrown off because the hi setting might be at -4%, im guessing it would still take out that 4% on top of the ve table change unless the hi setting was put back to 0, correct?

My 1300 mile trip might be a good thing after all, since I guess it's better to have mostly all of the fuel tables set to 0 and just run off of a ve table. Scott maybe when we meet up you can show me or teach me a few basic speed density theories.

Well, you can really adjust either the tunes (hi/mid/low) or the VE table. The result is the same. The tunes are in the software because they are easy to work with. Using the keypad, the car can be dialed in pretty quickly. Fine tuning with the VE table takes a lot more work, and the results are pretty much the same.

You want to dial the car in closely with the tunes or VE, so you won't have the AFR tracking working too hard.

Scott will fix you right up.

The VE Table is what the units algorithm is using. It just has other variables thrown into the main algorithm to adjust for imperfect VE Tables or to make life easier. The 'best' way would be to use the VE Tables to get them as close as you possibly can and then use the auto AFR to make sure they are perfect. I personally wouldnt be using the low-mid-high unless the car on just the VE table runs good at say WOT but too rich/lean at low throttle.. then you should probably use the other tables to compensate slightly. Thats how I am doing it at least

Thats what I meant. But using the ve table will be somewhat the same as the utec software. There are only so many "load" blocks you can use, I don't think at 2500rpm there can be 20psi, at least not with my car.
