hi all
im new here and have owned a r32 gtr for almost a year now and Love IT!!! i live in new zealand and dont really know anyone who can actually help me so thought someone here can being such a awesome site in all.So the mods done are very little which are catback exhaust,apexi pods with adapters,and removal of the boost restrictor now running 1 bar thats it.The problem im having is i'll start my car up let it idle warm then drive,now when driving for the first 10mins it'll run awesome hitting 1 bar exactly on my apexi boost gauge and holding,but after a few times of putting my foot down and running mint it will all of a sudden it will only boost .7 bar and no more and sorta feels like your driving with the handbrake on.It will boost 1 bar again the next day i drive it but always only for the first few putting the foot downs then back to .7bar which sucks.So i did the self diagnostics on the ecu and it gave me the flash code 34 which is the Knock Sensor code.So i rang nissan and said to the mechanic what the code was and he said that i need new knock sensors and that it doesnt mean my engines knocking ??? but it doesnt sound right i thought that code meant that your sensors are picking up knock so the ecu is cutting boost??? Ive tried new afms,a chipped ecu,new spark plugs gapped to .7mm. also with no result.its weird cos it doesnt blow smoke doesnt make any apperant knocking sounds by ear anyway idles and runs good and has good oil presure etc I cant figure it out
thanks in advance anyone who replies
