Alright lads

now ever sinse i put this management on my car its never run right and it doing my tit's in now. If you drive my car it drives mint but as soon as you go past 3500 rpm it starts to pop and bang like it back fireing. Ive got a oddkidd chip in and ive tryed everthink. before i killed my last engine i took it down to jano and he seemed to have fixed the fault but when i got home it started doing it again.
Now ive built a new engine because i snaped a rod in my old one. the car is just the same.
i would go to janos again but its about 300+ mile away and when i took my car to cenrtral day i seen jano and he put his computer on and there was only a tps code on so i reset that down there and its still the same
anyone got any ideas

try things like-coil- new denso plugs- all new engine sensors-new leads- cheaked timing and adjusted phase sensor- adjusted crank sensor- cheaked every wire on the loom from sensor plug to ecu plug.
ive also got a iaw that plugs into my car but the computer thinks my car is a cossie 4*4 still no codes.

would realy appreciate if anyone could help me
