Has anyone put a different dbw pedal in a 2000 Camaro? I am using a 2012 E38 with a stand alone harness. Looks like I have 3 choices---25835421 Corvette, 10379038 CTS-V, 12565643 Vortec truck. Just looking for something that might be easy to fit. Thanks!!

First thing you have to do is determine what vehicle/OS is for that specific part number PCM/ECM. Then you need to flash it with a proper VIN with SPS/Techline Connect. You will need the specific pedal for that specific VIN and wiring harnessOriginally Posted by Lakegoat
VIN is 3GTP1VE02CG125518
ECM OS is 12647991
TCM OS is 24235341
Harness is stand alone. I have powered up the harness and read the ECM and TCM. Car is not complete---just looking for info. It was from a 2012 GM truck. Couldn't I use the same model and year truck pedal?

There is a newer ECM OS for that VIN (12653249).
TCM OS is a 2007, it won't work with a '09-up ECM. It can be reflashed with a '09-up cal, though. The T42 hardware is all the same.
What matters most is that the Pedal, ECM and OS , and Throttle body all came out of a OEM setup. Miss matching them can cause a problem that there is no solution for.

Thanks Alvin,
The ECM is out of a 2012 Sierra, with original OS listed above.
I don't have a pedal. The part number above is a GM 1999-2014 Vortec truck pedal---will that work?
Also, I have a 90mm Throttle body, but not a Sierra, but a gen 4 and the plug matches---will that work? How do all these aftermarket throttle bodies work?
I can get the pedal and TB from a wrecking yard if necessary.
Didn't know this was going to be so complicated. I can tune it, but the matching stuff is making me scratch my head.
Thanks!!!

It doesn't look to me like any of the numbers in your first post are a truck pedal. Just looking on one of the online GM parts sites it's. C6 Corvette, CTS and C5 Corvette.
The throttle bodies have two TPS signals and have as many possible output combinations as the APP1/APP2.
The service manual will give the basics, but not down to the precision the TAC is looking for. You can have two TBs that both use the same description, "The TP sensor 1 signal voltage at closed throttle is above 4 volts and decreases as the throttle plate is opened. The TP sensor 2 signal voltage at closed throttle is below 1 volt and increases as the throttle plate is opened", and yet not interchange.
Yep, you are correct. The wiring harness instructions are not correct. I ordered the Corvette pedal 19417903. Seems like it is used by a lot of people doing these swaps. I don't have a clue. If my 2005 GTO Tb doesn't work, then I should be able to order an aftermarket 102 for the 2012 Sierra??
All this tech info is great, but doesn't get me any closer to a part number.

102mm? So, 800 HP N/A deal then?
Unless you need that last 3 HP, just use a $100 (or $40 used) 87mm truck TB that matches the ECM OS.
Closer to 1000 FW, I hope. Whipple gen 5, 3.0 blower, modified L83 heads, Bosch 210's, forged internals.
I can get a truck TB if it has a 6 pin connector. How do I know if it matches the ECM OS ? I don't know how to look that up. I spent some time this morning trying different searches to find what goes together. Most come up with CTSV or Corvette pedal and LS2 silver or Ls3 gold blade TB's. I have 2 of the LS2 silver blade TB's with 6 pin connector. If you look on PSI conversions website, that is what they suggest. I just made a plate to use a 90mm TB on the Whipple intake, so I guess I can use the same one for the 87mm. Still have the question above about--how do I know if the parts and OS match?
Thanks !!!

I would be looking at aftermarket ECM since you aren’t going to be using any other modules.
And how well do oem’s throttle bodies hold up to 1000 pd superchargers?

If it's stock replacement parts, you go to a parts site and 'build' the vehicle by putting in the year/make/model/engine/whatever else.
If it's aftermarket parts you're looking for compatibility on, unfortunately you have to ask each vendor individually what their stuff works with, if they haven't bothered to publish meaningful datasheets, which a whole lot of them do not bother with.
On my last one, I used a silver blade LS2 90mm and then switched to a NW 102---worked great. Picked up a few HP with the NW.

I’ve heard of driving issues on high hp of blower setups because the motor in the throttle body isn’t strong to open against the vacuum. I don’t know how much of a real problem it is.
I went to one site and for the TB, it showed about 130 different models that used the same TB--LOL
I looked at the new 87mm 12629992 TB's and they were in the $200's. A bunch of used ones 70 bucks and up. As soon as I get my pedal, I will hook up the ECM, T42, plug in the pedal and LS2 TB and see if it at least moves the blade on the silver blade 19420034. There should be a wrecking yard close to me to go snag a 87mm with the 6pin plug if the LS2 doesn't work.---

The first NW 102 had that problem---but what happened was the supplier sent out the wrong model with the weaker drive motor. It would partially shut on a wot run. The OEM did not have that problem.

Yeah, draw thru PD blowers are the only time big TBs are worth (possibly) the money and aggravation - depending on what you are really doing. If it's playing on the street don't bother. If it's for nothing but trying to hit a specific arbitrary number on a dyno maybe rethink the life choices that have led you to that point.
Blow thru or N/A the gains are just not worth it, most of the time, except maybe on the early trucks with the little, what was it, 78mm? The Gen 4 87mms are really good.
Hitachi is the OE supplier for the TBs GM bolts on at the factory, ETB0025 is like $115.

It's 90% a drag car. Just for fun---not going to win any titles.
Thanks for the heads up on the Hitachi. I did not know they were the original supplier. I don't mind spending a little on one of those.
