Is this true that the new versions from Japan allow you to make away with the air flow meter?

I am sick to death of air flow meters. fuel cut defenders etc etc.

Has anyone got one of these units yet? was it hard to install? how much did you pay for it ? where did you get it from?

How much better is the map sensor version compared to the air flow meter version ?

How much power did you get from the upgrade ??

what is the new version called? so I can be sure I am getting the right version ??

This is for a R33 GTST (RB25DET Series II)

Yeh i have the New Power FC Pro on my GTR R32

It eliminates the use of Air flow meters etc...It uses 2 map sensors for my car...

I got it done at Croydon Racing Developments

But the wait on the Power FC PRO is really bad...I waiting about 4 months for my computer to arrive...

It also gives u 2 new functions

which are :

Ignition cut for rpm limiter

and

Launch Control :P:):(

hope that helps

i think it was $3,000 including dyno tune and fitting...But i think i got a discount because it wasn't the 1st time i was there....

EVL R33- Well apparently you can use AFM with this computer...But Because i have a T88 the worst thing you can do is put 2 AFM in front of it.... The Power FC PRO was designed for drag racing..So it allows you to run to Map sensors im using the (3bar map sensors) I dont really think they made all different kinds of Power FC's only he normal one and the PRO...So if you have the PRO version im guessing you dont need the AFM aslong as you get Map sensors...

Hope that helped...:D

For most people keeping the AFM is not an issue. You have to be making a load more horesepower than most of the cars on this forum before an AFM (Z32 or Q45) is holding you back.

Of course the stock R33 AFM is supposed to be quite crap.

Before you race out and buy the Pro version, just check up what the different versions do. The reason I'm saying this is because I'm 95% sure that the Pro won't do what you want. From memory, the Pro version just adds a rev holding point when your not moving (for taking off at the drags) and a different way of rev limiting (ignition cut I think).

The one you're after is the D Jetro version. I don't think you can get a Pro version of the D Jetro. Anyway, do a bit of a read yourself, as I'm not totally sure of what I wrote above.

Cheers,

Michael

Took out possibly misleading info ;)

I dont know exactly:

I think it does something to the timing and fuel to put the engine under load without moving. I guess it does what all the other launch control systems do (they all build boost up).

I know for a fact that it does, I do it every day in my car.

Yeah the Pro has launch control and ignition cut rather than fuel cut, thats the only differences between the power fc and power fc pro. You must run AFM's with both these models.

The Power FC D-Jetro allows you to throw away the afm's and run map sensors.

Or so I was told when I was looking at getting a PFC Pro...

usually off load boost generation is done by cutting spark to individual cylinders in a non repetitive fashion, so the unburnt fuel ignites in the exhaust manifold and runs up the turbo rpm. Is a feature on some rally cars. Sometimes they just put an injector into the manifold and you get flames :flamed:

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.

      Infiniti Q60 Navigation Update

      By Chocolate Cheesecake. · Posted

      Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.

      Run it in open loop for now, and drop the frequency down. This lowers the resolution and requires more duty cycle to do anything, however good to troubleshoot.
