Missing link and VAFC?
I have a 95 civic ex, Greddy turbo, 7lbs boost, sometimes when I floor it my check engine light comes on for MAP sensor, I have a VAFC but do I need a missing link also or do I just need to set my VAFC a certain way, if so what do I need to do? Thanks!

Listen to this advise. This ended up being my problem.

Re: (tegunderpressure)
people really don't understand a blue box do they? the blue box uses a voltage clamp so you don't throw the map code so I would say your box is wired wrong.
also don't just get bigger injectors and use the AFC get a FMU and bigger injectors you will have way less headaches if you set it up like that.
I am a former afc "hack" user and the FMU, 450's, afc, missing link and fuel pump are a million times better

Re: (Blaze45)
that is the AFC hack if you use a FMU you don't manipulate map voltage as much. I will post my setting for a rich tune later on if I can...I can tell you at idle with 450's it is leaned 50% and at 8k it is only trimmed 17% it is stepped so you don't mess with timing as much

Double and triple check your wiring. I know a guy that had the exact problem you are having. He put a z6 swap in, and accidentally miswired a harness wire to ground when he was installing it. It was throwing a MAP code after he would boost. MAP sensor was good, it just took him forever to find the wiring mistake. He too was running a greddy kit with the box.
Also...you don't really need bigger injectors with an FMU. What I think you are considering are the following:
blue box/stock injectors
HP pump/FMU/missing link/stock injectors
VAFC/450's....the hack

Re: Missing link and VAFC? (diputs)
the wiring is right....but would it throw a code if the wiring is LOOSE? Im thinking there is a bad connection since it only thows the code every once in awhile. Not all the time..you know.
