well we have been trying to get this turbo to act right on his accord , something isnt right !!.he bought a FMAX turbo kit , Came with a mf2 fuel module and with 2 injectors before the throttle body. Well i just got the kit installed. Let me tell you a little bit before i get in to details , his ecu had been chipped with one of those spoon chips . Vtec cut in a 2500 and rev limiter was at 8500 . Advanced the timing curve and disabled the knock sensor . Also the car was running on 109 octane . I dont see how though , but he was putting it in there !! Well after the turbo kit was installed completely . The final excitment of hearing it run , well didnt get a perfect start up, it starts right up then dies. After pedaling it with the fuel it will stay alive . Then the check engine light comes on , after that , the car will stay runnning. rev up and turbo sounds good , . well taking it for the first test drive . easy on it at first , just to make sure i wasnt going to blow up or anything . When i cracked down on it , was slower than it was before , didnt even feel like the vtec was kickin in , like running with no vtec ? im at a lost here . im not sure if i got the vaccum lines mixed up or what ??? I ran the fm2 wires to all the specified locations . but when running down the road the turbo sounds great , spooling its ass off , blow off valve has a great sound . but its slower than before , so i sent him down to get 87 octane to lighten the load of fuel it was getting , is it possible being the o2 sensor is bad and isnt reading the air fuel mixture properly and casuing top end lag The codes that i got out of the ecu from the check engine light were a code 3 for the map sensor , thats most likely from not having the missing link to install , the other code was a 41 which is the oxygen sensor heater. . a new sensor might be needed or im thinking that the car cant run 109 octane with out the proper ecu with dyno tune. So what im asking if you know anything to help me out or guide me in a direction to get this PUPPY BOOSTED !!!!
