I will buy the throttle body from you for $50.00. Since it cant be made to work.
i am going to figure out why before I get rid of it. I tried adjusting throttle percentages down to 90% and it had no effect so I’m wondering if it needs the LS3 pin swap. I’ll post up here when I get time to mess with it.
I think I’d wait for your new harness extension first. But I agree that the China TB just might be the issue.
Lastly, only a max max effort LS1 would ever need a 102mm TB.
Good luck. Welcome to the LS platform.

Thanks. I can’t seem to find a silver blade, so I’m leaning towards and LS3 or LS7 TB now. I plan to supercharge my Z06 in the future, being that my competition at work includes a 2015 Mustang 5.0 manual with 4.10 gears and a 2018 SS 1LE Camaro with a Whipple 2.9 on top. Figured ah, just go with 102 everything so there’s room to grow later.

GM LS2 TB sits at 19.something percent when it’s energized and the car isn’t idling. It will drop down to 6-7% open when the car is started and idling
I installed the knock off LS2 silverblade and this was the result.
The TB would flicker as it ran through its diagnostic process and then fault, showing 99% open and throwing codes.
Maybe be the same internals as the Soler Performance LS2 TB that won’t work with a C5’s OS?
So I’m super psyched about my $150 paperweight. Guess I’ll throw it on EBay, listed appropriately of course.
I see, so same problem then. My stock LS6 TB value was ~15.3% with key on, engine off and no trouble codes. With the knockoff TB, that value rose to 78.8% with the key on and engine off. Some kind of programming issue with the aftermarket TBs.

It appears that only OEM GM TBs will actually work out of the box. Are any GM truck TBs any match? Or are they cable driven? When I think LS2 or LS3 I think strictly the C6 Vettes.

how are you adjusting the throttle percentages?
I'm guessing tech 2 or hptuners. Its all programed through the computer
First leave the adapter harness to stock and hook everything up and see how it responds.
If the throttle body tries to close then opens slightly the actuator motor is wired properly. If not switch the motor positive and negative leads.
If you still get the REP error then swap the power and ground for the TPS.
If you still get the rep after this then swap the TPS1 and TPS2 positions.
This is based on knowing how to re pin the harness and is easier accomplished on the throttle body end versus the harness connector end.
Following the steps above will net the proper operation. Then set the max value for the throttle body to 90% and you should be good to go.
My next project will involve adding a diode into the harness and this should negate the need for any tuning whatsoever at least as it pertains to the REP error.
Also this is based on the harness I used. I do not know the pinning of the harness you used so cannot guarantee that these steps will work. If needed I can take another picture of how I have my harness pinned.

thanks brother. I appreciate the info and help. We will see if it will work..... I’m less than hopeful and it’s probably just south **** Chinese product.
Anyone think there is a market if I get the parts and modify the harness people would buy them from me? Parts meaning throttle body and harness. Or maybe just the harness. Would still be less expensive then buying a "used" original silver blade and hoping for the best.

Without question I would say there definitely is. Sending ya a PM.

my HPTuners MPVI2 came in yesterday, got the credits. Currently trying to figure out how to unlock my stock ECM.

I’ll take that pic of how your harness is pinned please so I can compare it to mine. Yes, found out the throttle body side connector was way easier to re pin. How do I know which wire is which? TPS1 and TPS2? Also, how to set the max value? I got my HPTuners yesterday, did the verification code and got it connected to my computer. Next step is the credits and computer unlocking.

Here is the link to my trials with gold. The pictures show how the harness needs to be pinned for a gold blade. I think it is pretty precise and full of all the facts needed. Let me know if you have any other questions.
I am lucky in the fact that while I am decent at the software end, I have a degree in electronics and often had to make things play nice that didn't want to.

Thank you for that info. Lucky or no, I read your thread and found that rewiring the 4 pins at the throttle body end worked to get rid of the Reduced Engine Power message. Car will start then die, throttle percentage is at 6%. Probably need to modify the TPS setting in the ECM to stop it from dying out after start up.
To close out this thread for now, I was not able to get the aftermarket gold bladed throttle
body to work. No matter what I did. It would still
trip my cars limp mode and go into Reduced Engine Power mode. I ordered a GM silver blade off an 08 G8 6.0 and it’s been working great ever since. To date I have LT headers, a catless x pipe, Corsa catback, AFE Magnum CAI, GM 90mm FB and a FAST LSXR 102. Will
hopefully get the car on a dyno soon. Thanks to everyone who helped contribute to this thread.
Based on our PMs you had defective electronics in the throttle body you had before the silver blade. Either way it's good to hear you are up and running.

Happy to operational again. Yes, all things point to faulty electronics. I had thought about seeing if I could use the guys of the silver blade to operate the gold blades valve, but might skip that theory for now since it’s running well. Priority is to seal my headers exhaust leak(air tapping sound after install). Track should be opening soon, have a 2016 Mustang 5.0 and 2018 Camaro SS 1LE 2.9 Whipple to race. Good times ahead!

Short answer, Hell yeah, my car has been down for a month now after finishing the rebuild on this issue alone. I'm pulling my hair out trying to get it running so I can seat the dam rings and there isn't a soul in town that has a clue whats up with it, not the tuner, not the auto electric shops, no one. This is the first glimmer of hope I've found and if there was a plug and play solution I'd be all over it and name your price. Hell, I've probably blown a grand running around like a chicken with its head cut off looking for that very solution. although I'm getting no voltage to blue or green wires on the OEM harness so I may need a new harness there as well but that's not that big of a problem
