I'm still in the game, but no guru. I've finally started back on messing with my old 95xp800 I built a few years back. Couldn't get the fast parts to work, so I went back to stock and am STILL having odd issues. I'm convinced it's the 95 mpem giving me odd electrical inconsistencies. I too am looking at this zeeltronics ECU, as I saw on a fb group a racer using one. Any idea what they cost and if they come with the programming dongle?
