Hi, my car recently started pinking & i have owned the car for 2months.
It is manual 300zx twin turbo ,1992 with bmark chip(?) to run upto 1.1BAR,full exhuast upgrade with de-cat pipes,blitz induction kit,boost jets running 0.9BAR.
My problem is detonation,so i checked the timing & its was reading 15deg's & i have had to retard it to 9degrees to sort the pinking , does anyone know the cause of this problem as i have allready checked plugs,coils,ptu & cas connecitons.
Could this be down to the bmark chip (no info found on web about it,had a look at the ecu & the chip is labeled Z32M.440) ,does anyone know about this chip or anything causing this.
Pleeeeeeeeeeeease help me :confused:
Thanks alot ,
Muffin.
