one of the ECMs i got with the car the x-owner told me its an evo ecm. . .but on it i see someone has '4G63 RVR' writen on.

the numbers on it is:
MD311121
E2T37875
3Y20 E

on the side:
1121

on the EPROM:
EB63
3y12

not to sure matey.

but i have attached some pics of my old evo3 ecu if any good to you.

more.

kool thanks, well if you can answer this question i will know for sure that it is most likly to be an 'RVR' of some sort ECU. . .does all the evos 1-3 ECUs bolt up the same way? cause the one i hav here bolts up like ones you see by the center consol that bolts to the tunnel. . .after sayin all that all that maybe different between this and an evo ecu is the bolt patern.

isn't a RVR some sort of jap people carrier turbo'd but a smaller BHP

Yep. Some models had Evo running gear and a turbocharged 4G63 8)

Yep its an rvr ecu

so what is the difference between the rvr and the evo ecu?

depends on what processor it runs,if you look on Karl's picture evo's run mh6211
if yours is different then it will send wrong commands to the wrong pins + the eprom in it will be very mild i would imagine
If its the same processor then only the eprom would need to be changed
