OK got my Hypertech 52001 today and got it running. On the initial run it had codes P0930, B1633, B162B, B1421. I cleared those and programmed the XK. After the program I now have U0100, P0930, and U0431. I'm trying to find a list online with these codes but not having much luck. Oh is there any reason I would want to mess with my rev limiter or fan temp? I only changed it for regular gas and tire stuff right now.
My link to the specific codes doesn't work anymore but I'm sure a quick google search will get you what you need.
Here is a breakdown of what each digit of the code means:
First Character - System
The first character identifies identifies the system related to the trouble code.
* P = Powertrain
* B = Body
* C = Chassis
* U = Undefined
Second Digit - Code Type
The second digit identifies whether the code is a generic code (same on all OBD-II equpped vehicles), or a manufacturer specific code.
* 0 = Generic (this is the digit zero -- not the letter "O")
* 1 = Enhanced (manufacturer specific)
Third Digit - Sub-System
The third digit denotes the type of sub-system that pertains to the code
* 1 = Emission Management (Fuel or Air)
* 2 = Injector Circuit (Fuel or Air)
* 3 = Ignition or Misfire
* 4 = Emission Control
* 5 = Vehicle Speed & Idle Control
* 6 = Computer & Output Circuit
* 7 = Transmission
* 8 = Transmission
* 9 = SAE Reserved
* 0 = SAE Reserved
Fourth and Fifth Digits
These digits, along with the others, are variable, and relate to a particular problem
For example,a P0171 code means P0171 - System Too Lean (Bank 1)
I would leave rev limiter and fan temp alone. Are you getting a check engine light and then when you scan it these codes come up or no check engine light and the scanner picks up these codes? Which hypertech programmer did you get? Also most codes you can google and pretty much figure out what it is

never got a check engine light, they were there when I went into the program mode. I bought the 52001. I found stuff for a couple codes but the others had nothing for them...I think Sal's post pretty much sums it up as the ones I couldn't find anything for had numbers in the 4th and 5th spots.
