turbo ZC

I just finished putting a 14b turbo on a 89 crx with a zc engine. (Used stock turbo O2 housing too!) The problem is im throwing code 3 (MAP). I have a 2 Bar MSD map sensor. Still running 89 teg ecu. Also anyone know how to hook up and adjust msd fuel pressure reg. with boost reference? Throws code usually when normal driving NO BOOST.

ok, I'm not an expert, but are you using a missing link? you didn't mention having one and you did mention the MAP throwing code
