as for the '06 and up, this thread i think PRIMARILY has to do with the older 8-bit ECU's, you might start a thread specifically about tuning the newwer Consult-II ECU's... you might also look into what they do for ECU tuning for the Z33 and others, its probably a similar procedure...
NOW ONTO WHY I REALLY POSTED.
DeviousKA was nice enough to give me the schematic and PCB layout for the NVSRAM board for the U12, theres no reason that you guys shouldnt be able to use it too! (provided that someone modifies the code to support this, which would probably be DeviousKA) its worth mentioning that half of any profit will go directly to DeviousKA. Any questions you have should be posted over at the original thread over here http://eccs.hybridka.com/viewtopic.php?f=5&t=1772
regarding this, as i really dont check Nico too often, so post or PM me on http://eccs.hybridka.com
