i got a check engine light on my 95 civic dx wit sohc vtec wit greddy turbo kit using the greddy blue box.. the code is sayin map sensor but my map sensor is working bc the car is running perfect an when it is runnin if i unplug the sensor the car dies ne one have ne ideas lemme kno thanks

 

u need check valves or a missing link...that tells the ecu your not running boost...lemme know if you wanna buy a missing link, im selling mine...pm me if interested and make me an offer

 

the thing is with the blue box it shoulnt have a check engine light bc i had the isame setup in a 93 dx an it wasnt on how much u want for ur missing link

 

just give me an offer man, im also trying to sell a paxton FMU, stock used pistons and rods, and stock valve springs...give me an offer on the missing link

 

the blue box should intercept your map signal to your comp and tell it your not boosting. tricks it(kinda like a check valve or missing link accept its electric). your map sensor can only read i think 10 or 11 psi. if the comp sees more than one psi it will throw codes. maybe your blue box isnt working. or your waste gate isnt opening and your over boosting. boosting past what the blue box can hadle and its sending +psi signals to your comp
