Im new to the fuel injection world. I need to know what the difference is between the piggy back units that need to be plugged into a pc or dont and which one is better. Im thinking of getting the BIG GUN. let me know what you think
Power commander's need to use a pc. All other Dobeck style fuel controllers don't. Power commander 3 or 5 are best. Dobecks are fine for non built motors. I have a dobeck with a stage 3 cam, full exhaust, uni and lid kit. Works fine and is easy to adjust.
The dobek style efi controller (EHS) will be the easiest for the average rider to learn and adjust... especially if you're new to efi. If you don't have a built motor, it's what I'd recommend.
I have a Barker exhaust, UNI filter and EHS lid and controller... no motor mods. The EHS controller works just great. As a bonus... Eric at EHS is great to work with and will help you with any questions.
