My check engine light comes on, limp home comes on then goes out. getting p2020 code and gets worse as it warms up. p2020 is #2 cylinder misfire on injector bad ground or ccm, just put new injectors in. Any ideas?

Welcome to the site
Misfire can be fuel or spark-related. When's the last time you did plugs?

Where'd you find that description for that code? Searching the site here returns "P2020 Intake Manifold Runner Pos Sensor/Switch Circ Range/Perf Bank2"

It's 0202 from vivid racing tune kit.
Wait
So the code is P0202? And the bike has a tune on it from vivid racing?

Put the wrong code "0202"
No tune, just using the tuner to read the code and clear them.
Ok

Seems to be an issue with a wet or otherwise compromised connector at the #1 injector. What's the harness/connector look like?

My defender was running good until i started it up this morning. I let it idle while i was washing it and this it started to idle really high. Check engine light came on and went into limp mode. Codes that came up were p0246 and p0202. Could it be the battery sending lack of voltage or what...

Checked out both injector caps, clean and dry. Went for aa ride, still going in and out of limp home mode. Runs good up to 10 to 12 mph, and less trips over 6000 rpm. Midrange does good till about 185 temp.

I changed the mag side plug wire because it was hard, still getting 0202 and 0201 at 4200 to 4600 RPM.
And it's misfiring? Or just throwing the codes?

The check engine light, it misses, then it runs till it happens again and the limp home runs by on the screen and does it again over and over till I let up or accelerate hard.

It's hard to say it's misfiring, when it hits limp home it's running on 1 cylinder witch I understand that what it's supposed to do, than fires again and gets worse as it gets warmer or the longer I ride it. The RPM thing is more when it's cooler and warming up. Took my laptop with me last time 0201 and 0202 were coming up, I cleared them 4 times before getting home, about 3 miles.
Just spit-balling here, but I read where lots of X3 owners fought phantom misfire codes that ended up being caused by the MAF/T sensor. That 02 sensor code in addition to the misfire lends credence to the thought process. Do you have any way of swapping in another sensor? Hate to just go aim the money cannon at the thing....

Is that the one on top of the air box?
On your machine I'm not sure, it's typically on the intake "manifold" of the v-twins I'm familiar with
