Hi SAU, if anyone in Sydney preferrably close to Parramatta would let me borrow their z32afm (to rule out mine which I think is playing up) I would be most grateful. Its got its pins re-soldered btw.

Problem-maf cells jumping to and utilising wrong map points for 3-5 seconds under downshifts on load as seen on powerfc maptracer- causes massive rich n retard and power drop. This even happens with blocked off stock bov to rule out afm reverberration.

Normal driving in 3rd/4th at 1800-2000rpms is jerky and rough sometimes, idle is rough sometimes. Note that the blocked off bov isnt the problem here as it wasnt running jerky n rough the last few weeks with blocked bov.

Dont think its coilpacks as its fine under high load/rpm and always been-coils are stockies less than a 7 months old.

So would like to borrow someones z32 or CAS if it could be that?

Thanks

Ahk, if its when cruising at those sort of revs or trying to gain speed its likely to be too lean.

Do you have the ability to change values? Give it a bit more fuel between 1500 and 3000.

Yeh got the pfc commander and nope Yavuz has personally been thru it 2-3 times and says theres not anything he can see wrong in the tune, he said to change piping/ relocate afm/ test n report back.

I'm in Liverpool now, can you do.... Sun up? Sunday is ladies day, and she isn't much of a lady if I don't properly spend it with her. Though she's lazy and takes forever to get up so there is a reasonable timeslot.

I am almost twice as tall as a normal man and at least five times as wide. I look simply too big to be allowed, and so wild - long tangles of bushy black hair and beard hides most of my face, I have hands the size of dustbin lids and my feet in their leather boots are like baby dolphins.

I will also be the only dickhead sitting outside an open garage in my driveway at 7 AM.

Have you seen my fix for reversion? I guess you will tomorrow.

Reversion is not caused by the BOV, in fact a bov would help prevent it if done properly. I also don't believe in the pepsi can method, no no no.

Reversion is the AFM reading a signal from what is coming back out of the turbo. So when you shift and your turbo makes that zututu noise that would be causing reversion.

Reversion is most likely to happen when you vary the throttle or throttle off while driving. Especially when under load and then closing the throttle.

What, you want to pick the time??? I thought you wanted to borrow my Z32? Suddenly it seems like I owe you something :P Yeah ok, we can try for afternoon. I cant guarantee I will be able to but I can try.

So what is ur number n address brah? If u can txt me on the number I listed 8-9 posts up when u are free then I can come down. Reversion I thought is from all the air escaping back thru the bov return when u release the throttle..

Lol Darren I don't fit in the S14. Currently considering chopping part of the floor to mount the seat lower.

Furthermore, it was a quote from the first Harry Potter book.

I won't go there on that last bit. I almost need counselling for it.

It does sound like you have reversion issues and the best fix is a plumback bov as far away from the afm the better and closer to the turbo so it doesn't interfere with the afm signal

Also have you read on here of using a r35 gtr afm which idles better and doesn't get affected by reversion as much

Nistune has made a map for it but not sure how it will go with the power fc

Have a search it's on the nistune forums aswell

    • Not sure the US can import anything other than the C34 Stagea's, but if you can and you need to to tow, DO NOT under any circumstances get an M35 Stagea. If it is just as a family car and your country/state allows it, absolutely and definitely get an M35 (3.5L if possible as it is effectively a 350Z) over a C34.
    • Punch your VIN (nm35-xxxxxx) into Amayama.com You can see everything there quite easily.
    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
