Thread: RamJet 502 tuning

Tweet

I did the search function and found other folks have issues with the 502. My problem is at idle, the thing is pig rich and will foul plugs at every oppertunity. The fuel injection is read-only. deoes anybody here have first hand knowledge of these things and where i can get a program to talk to the MEFI IV system?
It says in the manual that these engines are intended for marine use and they must have an over-rich fuel curve for idling thru a marina or something. Even the name MEFI IV means marine electronic fuel injection.
Thanks, oj
