Power Fc And Map Sensor


Tabs
 Share

Recommended Posts

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??

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

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

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 .

    • Slap a 460L into the car, send its mum.  
    • So last night pulling away from the lights, I lost power for about 1 second. Bit weird, but I kept driving... 5 minutes later the pump completely dies. When I tried to start the car, the pump won't even prime.  I left the car for about an hour, tried to start it and it all appeared fine. Pump primed, car started, got the fuel pressure I should have.... Start driving home, 5 minutes later it dies again. I'm stuck in a shit spot this time going up hill with a car right behind me, so I just let the car continue to turn over while praying to the fuel pump gods. After about 2 minutes of turning the engine over, the fuel pump came back to life and I got home (only about another 5 min away).  So I've been digging around online, it seems like the 525 fuel pumps really don't like to be run at 100% all the time. I've found quite a few examples online of people killing their Walbro 525 pumps within about a year of usage when they are run without PWM.  So, my pump is an Aeroflow 525 (AF49-1057) and I've been running it at 100% without PWM. I'm thinking the Aeroflow 525 didn't like being run at 100% and has burnt itself up.  I really am sick of dealing with fuel pump issues, my current thoughts are -  1. Use a Walbro 450 and run it without PWM. It seems like these pumps hold up pretty well to being run at 100% all the time. I only make about 350kw and can't see me making any more power any time soon so this is probably a fine option.  2. Get a Walbro 525, run it with PWM. I know doing this will annoy me as I feel like with only 350kw, its extra expense that I don't "need" and I'll be thinking the whole time while setting it up that I should have gone with option 1. I know I'll be happy with this option when its setup and running, its only the initial setup frustration and cost as an issue.  3. Get a Walbro BKS1001 brushless pump. This is the fu*k it I'm already going PWM, might as well go full retard. This option just seems better in every way, with the only downside being cost. But I don't know much about this pump so I could be wrong.  Happy to get everyone's thoughts before I go digging around in the fuel tank again. 
    • Doing it this weekend. For sure this time. Thank you forum gods.  And im running map sensor now with the haltech. Still have the AFMs attached to the mushroom dome shaped air filter things
    • Actually, it is probably pretty legit. I mean, it's still woke feminazi bullshit academia, but you would have to agree that it is very likely that there would be a correlation between wanting a loud exhaust and scoring at the unpleasant end of the scales for dark triad personality traits. The fact that they found it didn't correlate with narcissism and only with psychopathy and sadism definitely shows that the loud exhaust thing is more of a "f**k you" than a "look at me", and I reckon that rings pretty close to most of the dickheads who take it to the extreme. Remember, this is correlation with tendency to be closer to one end of a personality trait scale than the other end. Of course someone who is at the literal opposite end of the psychopathy scale is going to be so considerate of others that they wouldn't even think about wanting to upset anyone with a loud exhaust. So the finding isn't that "you are a psychopath". Just that you score more towards that end of the scale than someone who doesn't like loud exhausts (on average, not necessarily even for specific individuals).
    • Blitz ER34 at some point hopefully, should be allowed in Gr3 if they do.
