Sure ill get a flaming for starting another "which ecu " thread but f**k it ere goes...
Far as i can tell for a r33 these are the main 3 options for an ecu in 1000$ range
PFC..second hand under a 1000 plus new z32 afm, =can be had under 1000$ but is S/H..
Adaprtronic is new needs no afm just under 1000$
Nistune=part new part S/H, by time u get chip, fitting,afm and Z32 ecu getting close to 1000$
If nistune did a bloody chip for 33 it would be an easy choice but they dont, pfc is definately tried and tested, Adaptronic seems to be getting mixed reviews...
So which would you use and why..??
