Hello, I just got all my stuff together for my 98 turbo GSR and I was gong to put it in today, I startd to install the blue box, Every thing is hooked up right (solderd every thing w/ new cold heat kick *** tool) i used the wiring diagram that come from greddy. Well I started it after I put the blue box in and the car started fine and warmed up fine but as soon as it got to open loop the car idled like shi* and when I rev it she sputters then goes, and when the rpms go back down it almost stalls. i called greddy and they said that the box was for a obd2 civic. Would this cause the prolbem. I also have a missing link and a 12/1 fmu laying around. could I use those w/out a hp fuel pump or am I just screwed? btw the turbo is not put in yet

 

BUMP If I use my rc 310's 12/1 fmu amd my missing link will I be ok with a stock fuel pump, 7psi

 

The box being for a OBD2 Civic would not cause that problem. Unless you wired it up according to the diagrams for a different year. Your problem could be a cause of too many different things. I doubt anyone can pinpoint the problem exactly with the info you gave. Try removing the blue box and see how it idles. Process of elimination.

 

It runs fine when I disconect it. and it ran "ok" but not great with it hooked up with out the map I also get no cel's

 

What do you mean without the map? The Blue box works with the stock map sensor. NO missing link is needed.

 

I had the blue box wired up with the exception of the map sensor
