What is the cheapest way to convert back to efi from a carb? I have an MSD 6010 and a highrise intake already. The engine is stock aside from an ms4 cam kit. I want to get good fuel economy and make decent power. Thanks in advance

 

inexpensive stand alones?

 

Most sensible plug n play option assuming you already have coils etc will me one of MSD's boxes for the carb kit.

If you dont have any of that stuff and are prepared to mount a crank trigger wheel 36-1 you could use Megajolt and the Ford EDIS coils

But yes you could equally use any suitable standalone ecu as ignition only although obviously that will be more expensive.

 

Megasquirt is an option. And probably the cheapest. You already have the 6010 to run spark so you could have the megasquirt run just the fuel. A mega squirt 2 could be had for $400ish.
