Just put one in temporarily until i get my ecu socketed.. anyone know the specs? Injectors size, rpm limit, speed/ boost cut removed? Any how are they for Aus? i hear they are made for Japanese Octane and climate?
They have: - Speed limit removed - Rev limit increased (usually to something stupid like 10,000rpm ) - Timing advanced hugely throughout the rev range to pretty much max out 100ron fuel that is available in Japan. (which is 2 octane higher than Aus) That's about it. Nothing special, apart from generally making your engine more highly strung - particularly if you're running higher than stock boost levels on our 98ron Aussie fuel. So, buyer beware of these "generic" style tunes. I recommend spending some more money and getting Nistune installed to your existing ECU, and properly tuned on a dyno, over these Jap tunes that are designed for fuel with a higher octane level than our Aussie fuel. Just my AUD$0.02 :zlove:
Stock. 7550rpm. Yes / Yes Fuel map - slightly less fuel up top. Fuel added at TP values/mid rpm. Up to 5 degrees more advance in spots.
most run around a 11:1 afr and too much timing for aussie fuel. good for numbers but you know what they say... ping is power
Yeah I've had plenty on before, not one of them didn't ping though, but that's just how they're tuned in Japan, I wish we had higher octane fuel (....'waits for E85 to come to Perth'). Boost obviously isn't controlled by the ECU side, I've had cars running 10-12psi making over 300rwhp and cars making over 400 on 18-20psi.... Just depends on the turbo setup, etc. My advise, even though it will seem like I'm trying to sell everyone something, get a custom tune to suit the fuel you're always using and modifications you have. Dropping in a 'chip' is like doing cocaine... It's fun but you don't know what it's really doing to your insides.
10-12psi making over 300rwhp mines ecu's make really good power because of the large amounts of timing at the top end of load/rpm scale... some over 32deg!!! but as i said, they're just detonation the &^%# out of their motors
Cant hear any Det. I think ill change it out as soon as i can anyway and give it back.. as for the "cocaine", im getting it from a trusted seller.. so my insides should be good.. its a pretty stock tune anyway, just smoother, 7300 limit etc
