I saw this cheat code on Facebook and want to know if it’ll help me get more performance out of my motor, etc. etc.

How did you even get that screen to come up? That is awesome! HMI typically means "human machine interface". I wonder if you're able to change button functions and unlock some cool stuff

That’s what I don’t know if anybody can figure it out please respond back or I’ll send my phone number to talk me through whatever I need to do. I would love to be able to tune my engine to get more horsepower since I have the presidential motor.

It gets you into the infotainment system, not sure how far removed the engine's computer is from that?

What is the ‘presidential motor’ if i may ask?

What year make and model is your vehicle? In the 2nd picture the button layout almost looks more like a K2XX '15-'20 Model year?
"Development screen". What is that?
Presidential motor?
Cheat Code on facebook?
You want to tune your engine for better performance with the stock oem setting menu?

There's a lot going on here...
