IMHO, which ain't worth a whole lot, the Pro-Jection System ain't worth the powder t blow it to hell.
One of the reasons you want to get rid of the BBD system is to remove yourself from hourly fiddelin' with the carb settings, cleaning, tuning, tinkering, swearin' and smelliing like gas.
If you just want the Jeep to run and keep away from the fuel delivery system, this system ain't for you. It's fully "tuneable," so you can tinker and play to your hearts content. It's also tuneable so that it fits a wide range of engines in varied states of repair.
From my experience most Jeepers are not really fixing problems as they crop up on the Jeep. Often the problems are masked. If it dosen't run too well just jack up the idle or enrichen the mix and everything's hunky-dory.
Well that is not a good attitude to have. It's much better to find the cause and fix the problem.
"Work-Around" fixes cascade upon themselves. It's not too long before the owner is really lost amid all the "fixes" that's been done for this or for that.
So, if you really want EFI, try something like the:

and another <a target="_blank" href=http://www.carflix.com/index.htm?loc=/tbi.cfm>Better DYI
, and if you'er really brave

Now I have my favorite (Howell) but you really need to do your research before you commit to ANY EFI system. You're not going to get something for nothing. You'll either pay in money, time, learnig or all three.
Think of the following:
1. The learning curve can be steep for some.
2. Installation is easy for the DYI'r if you understand basic wriing.
3. Are Parts easy to buy ANYWHERE?
4. Do you need a Manual to fix it in the field?
5. Do you need an 800 number to repair it?
6. Can the average shade tree mechanic diagnoise and repair the system?
7. Can the engine be modified and still have the EFI work?
8. Can future upgrades be done?
9. Can you take that expensive EFI to another, different engine (like AMC to GM)?
10. Will it really increase the reliability of the Jeep?
11. Once you install EFI are you willing to chase down all the other "Fixes" and correct them?
12. Is it worth the money?
These are only a few questions I'd be asking before I'd purchase. But which ever system you decide to go with... it WILL be better than the BBD or that Carb system trying to mask as EFI.
