Hi hondata,
What is the main diference in the MAF vs MAP fuel tuning.
I bought (pre-order) the flashpro because I want power and the correct AFR on the car.
I had a kpro (and before that a k100) on my old EP3 CTR so I know to tune fuel on a MAP calibration.
But my euro FN2 type R have a MAF also and I want to tune the AFR. Do I need to change to a MAP calibration?
can I tune the AFR with the a MAF calibration? if yes how?
What is the best AFR ratio on the k20Z3/K20Z4 at WOT and on part throtle?
And give us more information on this MAP/MAF fuel tuning please
Thanks
Nuno

A search on 'speed/density' and 'mass flow' should highlight the differences. On Monday the FlashPro help files will be available which have more information.
We've found that the MAP tuning is superior pretty much in every case, and recommend using MAP calibrations if the engine has anything more than an intake added to it.
However, the MAP calibration is a 'race' calibration and some vehicle feaures may not work. For instance, for US vehicles the oil life never decreases. Let me know what vehicle you have and I'll check.
We've found the best NA AF is 13.0 - 13.2:1 at full load. At part throttle you'll want to keep the AF at stoichiometric (lambda = 1, approx 14.5:1 - 14.7:1 AF depending on fuel).

I have a 2007 euro civic FN2 type R.
My car have a CPL racing exhaust manifold, a RRC intake manifold (from the JDM FD2 type R), a 60,5 mm exhaust and for now the stock intake with a K&N filter + the hondata reflash
So the best way is MAP tuning.
So can I use this 'race' calibration? (with the hondata group N reflash the "oil" light dosent't work and it's not a problem).
Thanks in advance
Nuno
