Haltech Q's
 

1. Just how good is it??
2. Can I use a MAS/MAF to get rid of that dang restrictive VAF(if so, from what car(s)??)

Thanx!!!

I thought that with most if not all ( I don't really know so...) engine management systems you could eliminate the VAF as long as you have the proper sensors??

Correct, you can use any type of air sensor the ECU will accept and the Haltek accepts MAFs.

While i do not have first hand experience with the Haltek, from Braden's experiences, it's a VERY versitle unit, plugged into a laptop, you can tune on the way to the track (i imagine other ECUs can do this too) but from a nieve POV (like i said, not much exp with aftermarket ECUs) the numbers Braden got from a bone stock engine, except for the leftover 3" turbo exhaust (121whp) are pretty nice. Although it takes a good tuner to get the haltek or any ECU tuned right for your particular application. I think thats the hardest part (aside from parting with $1200-1500 for the Haltek itself...<gulp>) is tuning it.

OK....

So i dont even need an air measuring device??

OR

Do you mean I need one and should use a MAF. If I need to use any ol' MAF, could I get one for a mustang (75mm) cuz that would flow really well.

Thanx for the input!!

u don't NEED to use the MAF because u can use alternative methods of air measurements (like MAP) easily when u r equipped with a Haltech ECU.

So basicaly, I dont to need to use any method of air measurment?? No MAS/MAF/VAF?? The Haltech does it????

No, you still need an air meter of some kind, what we are saying is that the Haltek can use any type. Braden used a MAP sensor on his set-up.

Thanks for the info everybody!! I have some extra money coming in soon, so I thought maybe it would be a wise investment/addition to my project.
