Default Are all EFIs created equal?

Thinking of converting my carb'ed chopper to EFI with an aftermarket kit.
The $2k price tag is gonna feel like a kick in the dick but I need the bike to start in cold weather when I don't have access to an outlet to plug in a heating lamp.
The 2001 Fat Boy is the first year of EFI for that model and it fires up in single digits without complaint.
Wondering if any EFI is going to fire the bike right up no matter the temperature or are some aftermarket EFIs better than others?

Usually, no one is going to make someone change their mind-
But 2000 dollars and MORE is a bad choice to fix a cold start problem.

I actually don't want to install EFI but how else do you get a carb'ed bike to start in single digits? (with no access to an outlet overnight)

How low of ambient you using this thing?
Recommended low temp oil, and a big bad battery with high CCA

actually...if your bike is tuned properly, the carb properly set up, your isgnition, starter, battery, all working properly...and you properly use the choke, a carb bike should kick right over. An EFI bike has to crank a while to get everything in synch. Where as a carb bike as soon as it starts to crank, curl mixture is drawn into the cylinder. Sure, EFI takes thecguess work out of the proper amount of throttle and choke. But, $2K seems a lot to fix this issue.

JMHO...

In a carport, single digits, harsh winds.
I use the standard 20-50 oil and standard 310cca battery.
Full choke, two twists, no cigar

Every set up is different.
I have to use more than two twists in the summer.
Does your engine continue to crank or does it quit?

The engine will start to crank and then it'll just make that rattling sound where the starter attempts to crank but the engine has no response.
So does that mean colder temperature=less twists?

Two things your battery is not doing the job-
It should be able to crank for at least 15 seconds.
And you prolly have to give it four or five shots when it is that could !
Every bike is different..
Plus read the FSM you may need a lighter oil in it for winter rides.

So instead of the two twists that I give it in the summer, the colder it is I should give it more twists prior to attempting to start?
