I have partial maps for the rvr x3 im not skilled enough to finish them you can adjust a few maps.
of note the mitisuibishi evo 5 rom dumps straight into the ecu and will run the engine but the transmission runs in limp mode.
you can find my posts below on the evom forum.
Of note the automatic gearbox is only rated for 330hp 510 foot pounds of torque or you will brake it.
