Power Fc And Map Sensor

[Tabs]

hello skyliners

just a quick question for now

i got myself a nicely rebuilt forged gtr this weekend gone

it has a power fc big single turbo 700cc injectors running 17psi and plan to up it to 20 or 25 psi but has stock air flow meters

i got told to go to z32 or r33 air flow meters but i was thinking would a map sensor be better ???

**can the power fc support a map sensor with another tune??

**would a map sensor be more recommended over bigger air flow meters??

I don't think the normal power fc can run a map sensor, only the d detro.

Swap it for a better stand alone ecu if you want to go down that track.

That's why you would have a d detro just to run a map. You get the power fc to run a maf. But get a vipec or autronic (whatever it's called) if you getting another computer to run map. Much better ecu

[paulr33]

you can't run map sensors on the l-jetro powerfc (the airflow meter version)

youd have to sell it and buy the d-jetro version and buy the map sensors and get it tuned

you shouldnt max twin z32s and its probably comparable to cost vs selling your current setup and buying a map sensor based system

or go FCON, tuning is easy nowadays.

Go adaptronic/vipec/link ect. Map sensor capable and a better ecu also can run dual maps for e85 and 98. Although nothing wrong with a PFC and twin z32s. You'll be doing pretty well to max twin z32s out.

just go map, everything works so much better and you can clean up your pipe work. i have had so many issues because of a maf setup that would be prevented with a map. plus if you get a map it will be with a better ecu.

Forget the FC and go a real ECU. Link, Vipec, Blackbox.

For the money you're going to spend on installation with the Power FC WITH the MAP sensors, you're much better off with another option. HOMEWORK!

ViPec and I assume Link plug ins work well and can used with either either MAFs or MAP . Goes in you std ECUs case so looks factory at a glance . I already had a Tech Edge wide band to do the oxygen sensing stuff but the V88 has all that std if you only want one box .

IMO you need WB 02 input and the ECU the ability to trim mixtures set by an AFR target table - for road anyway .

I'm far from being a good tuner but I fiddled all my start light load and cruise settings and I'm getting around (in Sydney) 13-14/100 on E70 . My 25 now uses MAP after having a PFC and Z32 and while I did get a bit better consumption with my tuning towards the end with the Apexi I wouldn't go back . I'm still learning with Vipec and MAP sensing and its slowly getting better and with modern injectors like IDs should be better again .

Be choosy with larger injectors because the best motorsport computer on the planet can't improve old tech injector abilities at really low pulse widths .

My computer reckons I'm idling at 1% injector duty cycle and its not too bad but could be a little smoother .

If I was you I'd get modern injectors first and change them over when the next computer is fitted and tuned .
