LS2 throttle body option.. Ok.. have my LS2 crate motor.. Should I:
1. Keep the TB and run "fly by wire"
2. Replace the TB with a cable ran unit (and whos?)
3. add and LS6 intake and fbody TB
4. FAST intage and cable TB
Thoughts?

Steve, I second with Mas280 in the harness situation. I'm swapping out my LS1 with an LS2 (+ a couple more cubes
) so it was a no brainer to do the FAST Intake. Because LPE is doing the motor, I will be using their TB. Rumors around the board are to stay away from the 'sticking' FAST TBs. Nick Williams appears to have nice piece which was my choice as an alternate to my current direction.Btw...YOU HAVE A PM!!!
Since you already have the LS2 throttle body I would set up you car for drive-by-wire and just get a FAST intake if mods are in your plan. If you're going to leave it stock then just stick with the LS2 intake.

How big a PITA is it to run the fly-by-wire TB? I was thinking a FAST intake along with a modified LS2 TB.. I sure wouldn't miss the big cable.. I guess I am concerned with how the FBW feels compared to the mechanical feel of a standard throttle cable.

I'm not sure what is needed for the LS2, for my LS1 I needed the throttle body, the Throttle Actuator Control (TAC), the pedal, and the harness between the pedal and the TAC. Your harness has to have a plug for the TAC also.
Check with Speartech for details, he is the one who set everything up in my harness and ECU

cool.. I've done some research and I think I will run the Fly-by-wire. Got a chance to check out a nice LS2/68 Camaro and I liked how it felt.
Now, will the LS2 TB bolt to a FAST intake? Also, who does a good job porting and polishing these out?
Thanks...

I am running a LS2 with a LS1 computer , I did a FAST intake and nick williams TB . seemed to be much easlier , aslso had a custom harness done for it and i am using LS1 style injectors not the small LS2 ones . Also FAST only makes one intake for these motors . SO if you put on a fast on the LS2 the map wiring wont hook up . The FAST map sensor is in the rear , LS2's are in the front . Just FYI . I wont have mine on long , just long enough to do some road test and dyno runs , then i am installing my HARROP intake , and then back to the dyno for some speed density changes !!!

Fly-by-wire is great The fly-by-wire is great, the FAST TB is not. I have two that are not going to be used on any of my motors.
The fly-by-wire has the TPS and IAC integrated in it, you have to buy a TPS and IAC with the FAST. If you have to go cable controlled, UMI is a much better unit and costs less too, AS&M and others have 'em.
Also I'm pretty sure you have to run a 2004 (Silverado) or later PCM (Vette, GTO or SSR) to be fly-by-wire capable regardless of who does your wiring harness.

What is the service number on the ecm? It is probably 9354896. Iam pretty sure you can flash this ecm for fly by wire. Ecms with service number 12200411 can be reflashed to accomodate fly by wire. This ecm was used in 01-02 F body, 01-03 Vette and 01-02 truck. So, if you flash this ecm with an '03 vette vin and get the pedal, tac module(from an '03 vette) and do some rewiring of your harness you can run the fly by wire. There are a variety of other computers out there to run the fly by wire but this is one of the most common and cheap to buy.
