I've been digging through some of my old obd1 90-93 accord ecu's and just for the hell of it took a look inside today. Supposedly these are one's you can't chip, but after a closer inspection of one I have labeled 37820-pt3-a22 it looks like it may be possible after all. Closer inspection of the board reveals the customary 74HC373ap chip that's usually added on to civic/integra obd1 boards to read an external eprom, and right above it is an external eprom marked m38256ap. It still uses the Oki M66 based processor as does the civic/integra models, although the accord unit is a M66911 and the civic model is M66207. I'm going to start looking into what may be required to try and chip these older accord ecu's, so if anyone has ANY info on board and hardware design, please let me know. I have a second accord ecu laying around, so I'm going to compare differences and possibly if this works out, maybe look into creating or enlisting someone with some computer programming skills to create a basic editor. If nothing else, at least pull the basemap off the external eprom on my board to give you boosted accord guys some kind of stock fuel/timing numbers to build off with civic/integra board variants.
