Quoting keydiver:
I think the 2G-to-1G ECU swap may be even easier. Its already been done, years ago. The 98/99 Flash 2G ECU's should be pretty much plug-n-play, I just need to build a cable/adapter for it. You just need to swap to a 2G knock sensor, and possibly the coolant sensor.
Anyone want to be a guinea pig once I get it sorted out?
so 98-99 ecu is reflashable too? If you make cables for it and are able to sell them, let me know, and if you decide to do the Evo ecu I'm down aswell.
