Well I have fitted mines ecu and am running 15 psi
car runs perfect no detonation.
Ran perfect at oran park outran r32gtr down straight and a few others I had a great time ps It has got a few other mods.
but ecu seems ok idles 600rpm.
My wife reckons I have finaly gone insane at my age
but it shore beats going on bus tours with the other over 60s
thanks for your thoughts on subject,good luck. Banno.
