Problems after installing Big TB on LS2
Hi.
I have C6 corvette.(LS2)
And it is installed LSXr intake manifold and afe air intake and 102mm big tb and diablo i3.
But it have probrem, Error code P1516 and P2119.
From the error code, I think that the adjustment of the accelerator opening is not working well, probably as a result of inserting the Big TB.
Is there a way to get TAC normal in LS2?
I am not good at English, so I rely on Google Translate.
I'm sorry if the expression is strange.

What brand throttle body? P1516 and P2119 can usually be fixed with proper tuning. The settings can be adjusted with hp tuners. Not sure if the diablo file adjusted or changed any throttle settings. But it can be 100% tune related. It could also be a throttle body issue depending on what brand it is.

I bought this in eBay...It's unbranded?
I set it up as described on the product page ...
After turning up to 4000 rpm, reduced engine power is displayed like every time.
Once the engine is turned off, it recovers and appears to be working normally.
Is it difficult to fix with DIY?

I have a NW 102mm TB on my 2006 LS2 C6, I can plug in either the stock TB or the NW & they will work with no configuration changes. There are tables that need to be adjusted for driveability & REP that I do with HP Tuners.
My motor is stroked LS3 which doesn't matter in your case, the E38 ECU is the same. 102 TB's are difficult for some tuners, you need software that will access the tables needed. I'm not sure your device will do that, have you contacted them?
