A cool feature of 2.0 HPT
and anyways back to cool 2.0 features....
somebody else on here sent me a pm showing that his vehicle has a value for changing the tach output resolution so you can use an aftermarket tach on vehicles....
now that kicks ***...

So why do you believe the LTFTs are correct?

Cant say to much for altitude but i can speak for the DA (MD see -1500-+3000) and still i dont see to much variance

they dont work for everybody...
lots of factors play into what the o2 are really getting...hell..even 1cm in placement can make a difference...a small unseen leak...
and yes I agree that certain o2's dont work as well in general..and it transfers to longtubes...
My own car proved it to me...
stock o2's in my JEt Hot tubes....BAD..
13111's in teh tubes and all of teh sudden it came to life..and my 13111's in teh jet hot location is very close to what my wideband says..not perfect..but real close

too much overlap and too much blowby can easily get them inaccurate

On the 3D contour map of say, a ve table, can you make adjustments by clicking a point on the graph and dragging it rather than just punching in numbers and watching the change?
Also, it says you get 2 vehicle types when you order a cable. If you only have 1 at the time of order (unless you guys add support for 98 Sierra 5.7s
) can you leave the other type open for later use? And if so, would that require sending the cable back or would it just lock to the first vehicle type you do thats different?

Yes, you can click a point and it'll highlight that area in the table display, then as you drag your mouse the value changes (that works on their 1.7 software also, only in 1.7 the graph and table displays are different tabs, now you can view them seperate or snap the graph next to or on top of the table display to view both at once)

But first I am buying a new set O2 sensors. I run rear type (145 watt?) in my front bungs per LG's suggestion, BUT I still get slow switching efficiency errors. I have heard the DENSOs are really good???
