Guys wasnt sure if you people knew as Microtech has just released there EVO8 standalone ecu. My brother got his last week and its really easy to use. THe ecu comes with a on-board map sensor so you convert to speed density right off the bat. probably about 15 wires total to run thats all.. it has 2-step,fan control, Aux, etc... he got his for a little under $1000. this has is the cheapest way to go speed density and full standalone.
