Hi sir , i have d16y8 engine
i user TD06-22G turbo+MSD HVC+JE piston+e-mange ecu +550 cc
Pistons -9.5:1 Compression Ratio , i need how to tuner this engine...

now i tuner 11-a/f on boost 1/kg ..my pistion now is thaw
Whether to recommend how to tuner my Air/Fuel Ratio thx.

 

Buy a Crome chipped P28 and tune with that. There's no reason to buy anything else in this day and age. There are so many free or near-free EMS's running around for Hondas....

 

Dear sir i have user P28 chip.. can you have other Better proposals.
If it is assumed that you tuner this engine, you will tuner how AF thx

 

When i get my car tuned, i just bring it to a tuner and run it on the dyno. The tuner will hook up a wideband which is what reads the Air/Fuel ratio. If you plan to tune it yourself, you will need to buy a wideband.

 

sir i have wideband o2 sensor .now i tuner boost 14psi=11 a/f
so i don`t know o2 Proportion is Too thin..
I want to know how much o2 is Security and the right..
can you help me more info thx.

 

You're doing it right so far. If you run 11:1 A/F you're actually a little on the rich side. Most people are tuning around the 12.1-12.4:1 range. You should have plenty of security

 

but sir why my piston have Melting??
can you give other good info thx sir.
