I see a "for off road use only" EPROM chip available on Ebay for $100. Other than finding a 99-2000 ECM off a V92C or SC & robbing the chip I wouldn't know where to source one. Used EPROM's are a crapshoot-one static electrical spark & the chip's toast. No idea if PMRT or any of the old sources can burn one? Possibly Rylan at The Vic Shop has a salvaged one? Good Luck
