A buddy of mine has the CB fuel injection on his 2276. I was helping him with syncing them and tuning them, and was not having much luck.
----------------------------------------------------
I have this system on my Buggy. syncing them is no different than webers.

He doesn't have any manuel or anything on them, so I did alot of guessing. First problem was the idle adjustment (on the box) doesn't seem to do anything. I went from the stop to 8 turns out, and saw little if any change.
----------------------------------------------
After syncing the throttle bodies set the TPS output voltage between .8 and .9 at Idel. This makes a big difference on how the Idel adjustment reacts.

Are little ajustments like quarter turn or less enough?
--------------------------------
1/2 turns

My second question is, does the fuel pressure increase as the rpm's do?
Set the pressure regulator to 45PSI at Idel The pressure should increase as the Load on the engine increases based on what the MAP sensor sees.

You can down load the entire manual off of CB Performances website. The best advice I can give you is have your buddy buy a wide band (narrowbands are useless) O2 sensor. Without one you are just guessing. Its the difference of a 10 minute or a 10 day dial in.

If you want to talk about it give me a call.

Any help would be appreatied

I syrcronized them ok, i just couldn't get the idle adjustment to do anything. I didn't know about the voltage at the tps sensor. Are you talking about a hand-held o2 sensor?
