Is the CompUFire VR still the best option 3 years later

Yep
You can only improve on perfection for so long and then it just is what it is.

CompuFire

If your bike is fuel injected then you should be using the 40amp 3 phase system due to the additional electrical load from the fuel pump etc.

08 Mastiff EFI, replaced VR, now voltage across battery 15.6 - 16.4 volts?
Causes?

 

[KaptinAmerika]

What VR did you go with?

 

[Gary Bare]

One from Bigdog
They sending new one free.
Told them check out before they send.
Hope new one works.
I just know the engine light stays on when i ride it. Goes off at idle, but from red light to red light comes on.

How did you get one from Big Dog? They went out of business in 2011.
Unless you mean Kansas Motorcycle Works or "Big Dog is Back" as they like to call themselves now.
If it is anything other than CompUFire or Cycle Electric I would not install it.
You should use CompUFire but in your case you will need the 3 phase 40amp system due to the additional power needed for the fuel pump, efi etc.

CompUFire 3 phase 40 amp system

There is a thread on here somewhere on installing it to a BD.

EFI bikes came with a 32Amp. Not sure why a 40amp is being recommended.

 

[Gary Bare]

Already replaced..40 amp
Working good.

BD referred to their charging system as a 40amp

"BATTERY & CHARGING SYSTEM
The charging system is a 40A system"

Certainly the carbureted bikes only need 32 but in the interest of safety I prefer to recommend the 40 amp system by CompUFire for the EFI bikes.
