pro-jection or q-jet?

I just recently bought a 78 scout with an AMC 401. The guy that owned it before me put a projection on it in the late eighties. I have been told by a few people that I should dump the projection and put a quadra jet on it. It seems like a good idea to me becasue it doesnt feel like a 401 and runs horrible when it is cold. The projection is a silver analog box with two injectors. Should I go with a q-jet or try and tune the projection? Thanks

Welcome newb :flipoff2:

Spend some time searching on Projection. It's a love/hate relationship. But there are a few tuning recommendations that may help your performance. Specificly line pressure both on the input and return, and your TPS settings.

With a little work you should be able to make it run better then a q-jet.

what is different about the closed loop kit?
The closed loop let's the Projection controller sniff it's butt and make minor adjustments. You still need to first tune the system in open loop. The key word is minor adjustments, you still need the system tuned in open mode.

It has an 02 sensor if that is what your talking about.
