inline pump with jb4 g4

Mortify · 05-22-2014, 08:59 PM

I want to buy the walbro 255 inline pump kit, so that I can run as close to 100% e85 as possible. Do I need the G5 ISO upgrade board before or can I get it after? I hear that I need a back end flash to run map 7 with a lot of e85. Is this not compatible with the G4?

If someone could break this down for me that would be great.

It would be a good idea to upgrade to G5 board. It can only benefit you.

As for running 100%, the hpfp can only handle E70 even with the walbro 255 lpfp.

You do not need the G5 but its a really good upgrade.

From Terry, "100% E85 works the fuel system harder with no power benefit over say 70%"
