im looking for a AEM EMS 4, i can buy outright or willing to trade for a AEM EMS pnp 30-1710, i have a boomsling harness so this ecu can be used for any years. I may also consider a trade for a ms3 with all the options. The reason im wanting to trade is so i can run flex fuel sensor for e85, series 1 does not really support flex fuel option.
