This is for you guys who want to install it yourself. If your in the USA, I really really recommend you just let me do it (its free!), but if your outside the US I understand.
If you have questions on the install, please post in this thread. Odds are someone else has the same question.
B13 Board Instructions
Note - Pictures are out of date there is no more battery pack. Also, second red wire that is soldered on the bottom of the ECU has been changed to a purple wire
This is what your ecu should look like when your done:
Ok, First off you need to install the header and set the jumper on the ecu like a normal daughterboard. Follow the instructions in this thread (this is an oldie but a good guide):

Next, if the thread on the ecu case where the daughterboard screws in have glue in them this needs to be chased out with a tap. I don't recall the tap size, I'll try to post this later, but you can use the included bolts to get it (its metric of course).
Now for the fun part. You've got six wires to solder to various ecu pins.
There is no longer a second red wire, it is now purple.
There are two wires to solder to the backside of the ecu (inner row of ecu pins): the long white wire and the long red wire. The long red wire
now purple is the back-up (always on) power for the daughterboard (goes to the 2-connector). After you solder these route them under the left corner of the ecu. Apply hot melt glue to hold the wires in place. Note the red wire is soldered to the third pin (and bottom row) from the left in the first group, and the white is soldered to the first pin in the third group (again, bottom row).
Now you've got four wires to solder on the top side, as show below. The blue wire goes on the last of the second group of pines, the white on the first pin on the next group, the short red on the 2nd to last pin of the last group, and finally the black on the very last pin. All wires are soldered on the pins closest to you, not the inner row. The black is the hardest to do, but if you note there is a little notch in the blue connector that will allow you to get your soldering iron to it.
Now install the daughterboard. The USB cable is inserted through the hole on the back of the ecu first, then the daughterboard screwed in place. Don't be afraid to put some elbow grease into it, sometimes the screw holes are slightly off. Make sure to clean any metal shavings from the case.
Last insert the wires in the correct order into the plugs, and install the battery pack. Make sure your wire order is correct! The long red wire (bottom side)
now purple goes in the two connector next to the battery pack connector (batter pack connector is marked AAx2)
battery pack no longer present, and the short red wire (top side) goes in the four connector. Note the batter pack and car power connectors (the two 2-pin connectors) are pinned out opposite to each other.
Follow the instructions in the quick start guide to flash the ecu before installing in a car.
B14 Board Instructions
If using a B14 ECU the mounted pads for the board will need to be drilled and tapped (use a M3x0.5 tap). For the P10 and S14 ecus these are already tapped.
Install Ribbon cable in top most row of 40x1 holes on the ECU (marked W001). Move jumper (0 Ohm resistor) and R025 to R022, as shown below.
Solder yellow, blue, white, and purple wires to backside of ECU as shown below. After soldering, test for continuity to make sure you didn't short any pins together, then cover solder joints with hot melt glue.
Optional- solder 59k(EGR delete) and 470k(rear O2 delete) resistors also to back side of board, as shown below. The wires in the above picture are the pins for this (pin numbers also given in the picture). Sometimes this works, sometimes it doesn't.
Solder red and black wires to topside pins as shown below.
Mount ECU- thread USB cable through hole in back of ECU, and install battery. Zip tie the USB cable to the diagnostic screw bracket for a strain relief. Screw ECU board in.
Install wires into housings, and connect to ECU. Make the order the exact same as in the picture below (wire colors are also printed on the board). Ignore the orange and big fat black wire in the picture.
