How to convert from masf to map r32 gtr. Help?

[Skym]

Stock GTR ECU with Nistune would be good enough. Stock GTR ECU has temp compensation (IAT sensor) and is MAF.

If you're considering cheap cost, power FC is probably the best bet. MAF (L-jetro) is fairly easy to find for $1000 or less with hand commander. Forget the MAP setup, stay maf.

apexi L-jetro --- +datalogit + Copilot software

thanks for all the imput guys. i am thinking of going aem ems but i would like to go map instead of maf. there are so many problems with maf sensors and they always go out. i might look into going with z32 maf s tho. i have talked to some guys at forcefed and they say ditch maf and go map. i dont plan on tuning myself. i plan on getting tuned.

Faulty MAF's made me want to go MAP as well. My thinking at the time was "Why buy new mafs for $600(for the pair if you buy from Japan or $600 each if you buy Z32's local) when I can buy an EMU for $700 and go MAP." Two malfunctioned EMU's and $2000+ in tuning time later I scrapped it for new Nismo Mafs and a PFC and $200 in tuning and the car runs 200% better than on the EMU.

Moral of the Story: Don't cheap out on EMS if you want to go MAP and find a tuner that knows that EMS and the GTR.

Side Note Moral: Don't waste money on used MAF's and buy them from Japan, from one of GTRC's reputable vendors.

Side Side Note Moral: Stubbornness can be expensive. Jason, Eric, I should have listened to you sooner.

Best bang for the buck, nismo MAFs and power FC.

EMS ain't the best for what you spend.

I use EMS as a general term for all stand alone units. Not referring only to AEM EMS.

I was chatting with a guy at Vipec and he claimed their system could be tuned for a MAP fairly easily. I would try and find some one who is using this system and find out what sort of tuning time was required for MAP.

I run the ViPEC and tuning was probably about 2 hrs on the dyno. This system auto tunes fuel to whatever AFR you command (and does closed loop trimming in real time while driving), ignition timing is whatever your tuner figures is fast, fun, and safe for your car. I just tuned and went racing. The car has run like a champ on this ECU. The first two seasons were at just under 400 rwhp with (very) non-ideal cam timing. This summer was at 525 awhp with correct cam timing and about the same boost as before.
I daily drive the GTR in the summer and the tune is great on the street as well as the track. Torque comes on strong from about 3500 rpm and builds linearly until about 4200 rpm, plateaus, and starts dropping off around 6500 or so. Power is still climbing at 7500 rpm.
