just want to mention that in your guide, you had addressed ECU remappings with the limitation of about 20 awkw.
this is infact, untrue, as i believe the stock fuel maps for an RB26 ecu are 16x16 fuel maps, which allow for plenty of tunability.
such examples of the level of tunability with the program called ROMeditor and a stock ECU can be seen on the Mine's skyline, which beat out the Amuse Supra on the BMI Inline 6 challenge.
also, note that some of the IC's on the board, mainly the CPU in which the fuel map binaries are stored are easily burnable with the proper equipment, such as an old Pentium MMX computer with the proper AmiBIOS chipset on the motherboard. These, coincidentally, have the same size socket and same type of flashrom onboard, and have a feature called "bios cacheing" which allows you to turn the board on, and boot into DOS, then you can pull the bios chip out of the socket, insert a blank one, or a RB26 one, and trick the computer into flashing a fuel map onto the new chip using the motherboard manufacturers firmware update.
the sockets on these boards have the same pins, same eeprom, and same size.
more details on this can be found on the web in various places. mostly japanese. you can also look into hacking xbox with a "homebrew eeprom" chip, which gives you a more detailed explination of the above.
after reading my post though, i hope you guys understand that it's not as easy as it seems. sometimes you have to go through leaps and bounds to get the proper setup. but as i've stated, the tunability has far greater potential than just 20kw.
