you dont need one why do you want it??? its not going to helo you yet, you only need one when running more than about 11psi. but you do need hondata, uber, aem, and some people have used a safc.

A 3-bar MAP is to be used in conjunction with a set of larger injectors, without a FMU. Your setup doesn't need one and will not be able to run one.
