MrFred, I've been working on the 98 and 99 DSM H8 ecus.
They use the same processor and much of the same code as the Evo5/6.
If you need info on something specific, I could probably help you out.
I have defined every 3d map in my disassembly and am starting to write code for a set of Mods like Tephra's. So far I have a 2-Step coded. This could easily be adapted to the Evo5/6.
Rolly1818, yes you need the 0P 2.0 to flash the H8 ecus. Some of the Evo5/6 XMLs could use some updating.

Cool. Would there be any posibility of two step or wideband logging being adapted to other H8 based mitsus? Two step would be a HUGE help in getting off the line with my pos fwd 3g. The only thing I have found by dumb luck is the immo code location.

Did you get anywhere with finiding unused ADC inputs for the E5/6 ECU's at all?
I know that one potential possible is to use the park/neutral switch that appears to have been carried over into the later cars code from the early Evo ROM's. This is the one that I have utilised on my Evo3 to get switchable maps etc.
I've just recently written a working launch control code for the E5/6 and was looking at switchable maps next of which writing the code is the easy part but getting the unused ADC input and associated ECU memory location is the tricky bit
and so I just wondered if someone had already done the work for me 
Many thanks for any help you may be able to provide

If you just need a On/Off input, you can use the Base Timing Adjust Pin, it isn't used at all. You can also use the Park/Neutral Switch or the A/C switch if there is no A/C, but they are used in the code.
The H8 ecus have a built in Map Switching that is used for Automatics.
If you look at the Ignition or Fuel Map Lookups:
btst.w #7:16, ????:16 ; Is the Hi Octane Map Enable
btst.w #5:16, ????:16 ; Is the Park/Neutral Switch.
Just need to change a couple map addresses for realtime map switching.
