Corvette C6 Z06 weird idle

[Emastrong]

Goodmorning everyone, I'm working on a 2007 C6 Z06 that is getting weird acting on idle, it's stuck at 1300 rpm and then drops to 800rpm after a while. I checked for leaks with smoke, replaced throttle body with a new one, cleaned all the contacts, replaced the gas pedal too... Anyone got suggestions?

Tune and log. Without that all that anyone can do is throw out guesses.

Suggestion is, post a log and tune file along with all the vehicle specs. Otherwise how is anyone to know what you have going on? That's like saying "My car goes tick tick tick. Can you tell me what that is"?

Happens all of the time on the Camaro5 forum. "My car makes a weird sound. What is it?"

As you can see the car fits an edelbrock supercharger, it runs great and had several miles with it suddently it started acting weird.

In the log i did in the morning with cold car it starts really bad and gets p1400 dtc.

After the car warms up it starts good but the idle is weird as you can see

What other mods? LT headers? Cats, no cats? What injectors? List them all complete please.

Does it have a 102 throttle body?

I just fitted the e-force supercharger kit for the car it has got different injectors but i don't know the spec of them they're along with the edelbrock kit.
Complete corsa cat-back exhaust with manifolds.
No other mods for the engine.
It was super smooth a great car, used for more than 4000 miles.

It is not setup correctly. The ETC scalar is setup for a large throttle body. The idle airflow table is way too low. There are many problems with the calibration. I guess it was by sheer luck that it ran good for 4K miles.

It seems a bit weird to me that it run perfectly for 4k miles "by luck", I mean it's 4k miles not some startups...

I'm just telling you what I'm seeing based on my experience. Some of it doesn't make sense.

Hello everyone, after many changes on hardware, like the gas pedal, the throttle body, checking fuel pumps, spark plugs and many more things... I ended with changing the ECU. Then remapping using the hardware that came with the Edelbrock e-force supercharger (which I did on the previous ECU many times before changing it) now the car works, it seems that it was the ECU itself that gave the problem.
