I believe my MAF is going bad and I have a powerFC i haven't installed yet. I understand it will run fine with the base map that is on there as a stock car but if I change to a Z32 MAF and select that in the powerfc will it still be ok to drive or will I have to get a tune?

Reason why I ask is that if I replace the maf it's going to be a Z32 maf, i don't want to have to order a stock R32 maf only to replace it soon after getting the car running properly, and I want to make sure it will run fine with that if I select that in the powerfc so that I can see if that resolves my problems.

Also I know probably someone is going to suggest to borrow a MAF from someone. I have 1 of only 2 skylines in my state that I know of, I lived in the US, so I can't do that.

Thanks for the help ahead of time.

So it looks like it should be ok, thanks for that link saved to my favorites. Hopefully I have no issues with the shit fuel they have here. (equal to 95 or 96 of how you guys measure it)

Reading that FAQ looks like I might, good resource that.

edit: Any suggestions on how much timing i should pull on such shit gas?

Meaningless question is meaningless. You find out how much timing you can "pull" when you tune it on the dyno. No answer we can give you otherwise will be in any way accurate.

Well I mean you can give an aproximation or a starting point. It by no means needs to be perfect but would need to be enough to test functionality or drive to a dyno.

If you have a hand controller then leave the timing map as it is on the base tune (as above) monitor knock and use the inj/ign screen to take a few degrees out if you get some knock. Add a little bit of fuel as well. Don't drive like a dickhead, keep it off boost and it should be fine. If you don't know what your doing and don't feel safe driving it like this then don't do it. There's no harm in ringing your tuner and asking him for advice as well

if anything just make sure your base timing is set correctly. the default powerfc map will be fine. Just make sure you run through its first time startup procedure with your z32 selected before you start and presumably after you've installed it. Stock map has lots of fuel and near stock timing...like the others have said...just drive it sensibly to the tuner and you'll be fine.

    • My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.
    • Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?
    • What about if you just give it direct 12v and earth?
    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
