i like it a lot. but i have one comment maybe someone can help.
on this secstion saying
D. ACD unit fault – 3 solid lights
When your ACD unit has all three lights on at the same time (other than at startup), this means your car is reporting back to Mitsubishi headquarters that your warranty should be voided… Just kidding. As stated in your owners manual, this denotes some kind of error in the unit and it needs to be serviced. To service the ACD you need a very special, and very expensive tool from Mitsubishi. This tool is used to engage the ACD pump to bleed the lines. You may run into this issue if you are changing out your transfercase. (6)
well yes i been geting that but i have a small batt. and wondering if it is becasue of that. well i turn on car some times all 3 come on and sometimes no. and then if they do come on after 3sec car on. i drive and i just kill car and turn on again and its fine. so i dont see what is up with it. lol . is it the ACD fauling. or is it just the small batt not getting enought power on start up and giving it a fauild code.

I have to correct some of the things mentioned here 
I have a Ralliart ACD ECU in my EVO7 and it does not work together with the AYC. When SAYC was introduced on the EVO8 the control of the AYC and the ACD were indeed put together and controlled by the same ECU but the Ralliart ACD ECU’s only work with non AYC equipped cars i.e. RS versions.
I guess that either the ECU for the EVO7 or the ones for EVO8 RS might work with the USDM EVO8 and/or EVO9 since they don’t have AYC but I guess we won’t know for sure until somebody tries it

- Because Mitsubishi didn’t want it to. Sucks for you. See Section II - A

Hopefully the Evo X will be redesigned to accomodate both.
Great info, Terry.

Thanks for the kind words everyone
By the way, my next one will be the Evo IX MIVEC system. Shorter and easier, but I'm still seeing people asking questions covered a dozen times over...Terry S
