are the ftc's actually different in some way or are the base map just different and all i would need to do to change to the new truck is upload the correct base map?

There are about 50 different models of FTCs. About 6 now are only available through URD.

For the 5vz there are only two. E and Non-E. However both will work on any year, but the E Function only works on trucks with front O2 sensors and not the new Air/Fuel Ratio sensors.

So, yes you can install your FTC in any 5vz and simply retune the map.

I had a passing thought about the 'ultimate' FTC.

If they could engineer an FTC which combined a wideband O2 add-on sensor, and an OBD2 code reader, you could in theory, easily make a unit which could tune itself for both open and closed loop. Hook up the OBD reader for tuning, and leave the wideband sensor in place always, so it's always able to optimally retune for performance.
Maybe this could be the CARB legal ticket for the turbo kits.. It would be a fully sealed box which self-adapts.

I suppose going to school for Comp Sci makes one think of these things..

There are stand alone units that are supposed to be self tuning to some degree, but not a single one of them works as it should, none of them.

We are always looking far down the road and we are keeping our eye on several things that are in development and we do consult with a few of these companies and when something better is ready, trust me we will let all of you know about it.

installed my third URD kit last night, it took 3 of us 3 hours, the owner of the truck got ahold of some supra 305cc injectors, everything else came from URD, the initial test drive went very well, the ping is gone and the power has improved about 10% the owner said with the start up preloaded fuel map, we will wideband it and fine tune this weekend.
when we first started the truck the CE light came on and stayed on during the first test drive, we got it back in the garage and looked it over and saw no problems and havent seen the light since the first startup.
has anybody else experienced a CE light when doing this and did you check the code?

was it blinking or solid on? I had mine blink for a while (right after the install) and when I got it home there was no code. A blinking light means there was a missfire and I attributed it to improper spark plug gap setting. I re-set all plugs and haven't seen it since.

I had it as well. Mine was MAF signal out of range. It was from sitting withthe key "on" but not running for too long, then "off", then "on", etc... I had to power the FTC for mapping and left it on while monkeying around. If it doesn't run so many # of cycles in the correct range it will trip it. If you turn on and off repeating with out running the motor it will sometimes throw it. I don't remember how many trips it take before it erases it(20 or 50 cycles?). No worries. The flashing CEL is the one you don't want to see.

My CEL also comes on when I disconnect the battery. Its also ways P code...meaing MAF error of some sort. Most of the time is P0101.

Scratch that idea then :) As a computer programmer, I was readin the U-tune guide and thinking how easy it would seem to have a simple program which would tune according to readings from the OBD scanner and the wideband O2.. maybe it works better in principle than practice :)
