All of a sudden throwing 2 codes. Code 20 Electrical Load Detection and Code 21 vtec spool solenoid
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. Both of the codes are being thrown at the same time. Any idea whats going on?

Make sure you check your fuse box. I know on my OBD2 motor, id get the similar code for ELD, When i had this, my speedo wouldnt work. I checked both times it happened and it was always a blown fuse #16. Might wanna check that.

Code 21... check your oil and VTEC solenoid wiring at both ends.
Code 20... I've seen OBD2-1 conversions throw this on occasion. Do you have ELD disabled in Uberdata?

well i tried disabling eld and it still threw the eld code
. I actually ended up fiddling around with a bunch of stuff like filling the oil up a tiny bit because it was kinda close to the lower dot, but wasn't really low. I also put on a brand new alternator belt, and fiddled around with some wires looking for shorts. Now it seems to not throw the code. We shall see though.

well i ran a wire to the vtec solenoid and it clicked so i guess that is working fine. Whenver the cel comes on vtec is definintly disengaging. Then it won't turn on after that until i turn the car off and reset the cel.

Try pulling the solenoid off and cleaning out the screen.

I figured it out. Something shorted out in the ecu because the car runs fine on my buddy's ecu with my chip in it.
