Evo ECU Reset after Clutch Upgrade..
Ok i just put a stage 3 clutch in my 05 Evo 8.. After i put it all back together My Ecu is all messed up... It has reset but it is still being stupid.. all three of the Ceramic,Gravel, and snow lights are on. My Check Engine Light is on and gas millage is ****... To make it easy it is running like hell right now... Anyone Know what i need to do?? also with the new clutch in it kinda shatters at a take off. is this becuase it is new and is not broke in yet? any help would be great..

Did you bleed the ACD pump after you did the clutch job? IF not, that's why your ACD lights are on, hopefully you didnt destroy the pump.
Check the codes to see what the CEL is about. Also you could check the obvious... boost leaks, etc.
Your describing clutch chatter, different clutch materials / design have differing amounts of chatter. A puck/paddle style clutch will have more chatter than a single disc style clutch.

Keep your rpms below 5K and no launching for 500 or so clutch engagements. City driving is the ticket. Alot of peole recommend 500 miles but if the majority of your miles are highway then that may not be enough. A puck style clutch's engagement is going to be rougher than a single disc, combine that with a lightweight flywheel and your going to have some chatter. It will probably get a little better but I wouldnt expect major miracles.

Reset ECU : Remove battery terminal and put it back on. For the engine ECU you can just remove the 20amp fuse closest to the front of the car in the underhood fuse box instead.
Check Engine Light : Autozone, they can read your code for free, search the OBD2 code when you get it.
3 ACD lights : Did you/they bleed the ACD system after installing the new clutch? You have to bleed the ACD after changing the clutch if you took the banjo bolt off to get at the last transfercase bolt.
