honda tuning got an article about homemade turbo for a crx, i was wondering if you needed a zdne ecu or some thing to control the fuel for the turbo. do i need to upgrade the computer if im running 5 to 6 pounds of boost. any tech would be helpful and i have check most of the homemade tubo pages,

 

In that article they were just running the standard fmu/fishing check valves... that thing made pretty good power on 6psi.
