Default All of a sudden throwing 2 codes. Code 20 Electrical Load Detection and Code 21

For some reason now my car is randomly throwing these codes whenever I let my rpms go above around 6000 rpms and there has to be a good bit of load on the engine...like at full throttle. Its throwing both codes at the same time. Any idea whats going on?

Alternator?

ELD would fire because of a lack of current in the system right?
VTEC might not be able to fire the VTEC solenoid if the voltage is lower than 12v

Random guess really...

thats what i'm thinking. Any idea why it would happen at high load in high rpms and not at other times?

Nope...my car is doing this ramdom weird thing where the battery light goes on in the higher RPMs and I think thats alternator too.

Not sure why it happens in the higher rpms...

well whats weird is that this has happened ever since i tightened the alternator belt..which was squeeling from me not tightening it enough in the first place after swapping in my new motor. I wonder if that has anything to do with it.

Sounds like a correlation to me

do you know if having the alternator belt too tight or anything would cause a strain on the electrical system.

No i dont...but common sense tells me it could.

Try playing with it...loosen it up a touch. Maybe its too tight and slipping at higher RPMs

Ok well loosening it didn't work. It just made the belt squeel. Now that i tightened it back up it still squeels so it looks like its time for a new alternator belt.

What about disabling ELD through uberdata? Is this a bad idea? It seems like it would just be like cheating and overlooking the problem that is present.
