How about any time your standard AFM maxxes out? Which is about (or a bit more than) 300 engine HP. You can go past the AFM max out point, but if you want to retain the ability to control the mapping, it's worth upgrading.

this, although its more like 300rwhp (varies from car to car obviously) than 300bhp

Thanks guys,

actually I am not sure what sticker is even on mine. might have to duck outside and have a gander.

Anyway i was aiming around the 250-280rwkw with Hyypergears ATR43 SS1.5 so i guess i will need one. Just out of interest are the the same physical specs as a stock gtst one as in would the mounting holes match up to the standard airbox. I need everything to look as much as standard as possible....

Ps: I forgot to ask, has anyone seen the aftermaket z32's on ebay (brand new)? any thoughts...

for example.......

hello

ECR33 AFM is 80mm and maxes around 220rwkw ish, some can do more, some less, but they all peak 5v around this level

VG30 AFM (or Z32 we call it) is 80mm and maxes around 400rwkw ish, some can do more, some less, but they all peak 5v around this level

both are a direct swap for the physical diameter and adapters but the wiring is different

ECR33 S2 is pink label 3 wire and VG30 is orange label 4 wire (extra ground wire)

there are also Z32 (really VG30 AFM's) fake on ebay so do not BUY fake ones

a legit Z32 brand new costs $350 ball park and comes in an orange BOSCH box

look at the pics of this page for a fake Z32

also Ive never seen "green" plastic based Z32s like that EBAY url you posted, they are knock offs or fakes or copies or shitters

cheers Paul, thanks for the heads up...

I often wonder about ebay copies and I would love to know what the green maxes out on though. would be an interested experiment

has any members bought something like this "a fake" and got some real testing from it like what was on Pauls URL above with maxe rekw & voltages?

That specific ebay one isnt a Z32...

It's a dead give away with how the ad is worded. Notice how it says "aftermarket Z32", as in - not original. No where does he say it is OEM/Genuine etc. The last line of his ad says "check other listing for genuine"

That's so he can cover his ass when you realise you've purchased a paper weight :)

His genuine ones are selling for $320 or there abouts.

that link states its an aftermarket replacement and to check his other listings for genuine stuff so theres nothing dodgy going on there.

alot of the older fake z32s worked fine in every way, they just maxxed out at much lower power levels than genuine ones.

if you end up getting one a cheap solution for the plug is to get a rb30 afm plug as they're the same.

Pfff do not be telling people that fake Z32 AFMs are any good. They are not.

We are talking about a extremely sensitive and critical component of the fuel system here... "she'll be right" doesn't cut it!

It's not just about "peak power" there are many other factors at play here not least of which is consistency & reliability

Of course if it's just for your fully sik drift car with lots of go-fast stickers on the side then go for it! :D

agree the AFM is not something that should be mucked around with

its one of the key sensors the engine uses for engine management

why do you think it rev caps at 2500rpm as a failsafe when the AFM is mangled, failed or unplugged

cos its not safe to run with a mangled one or non-working one

Chinese copy Z32 AFMs are an absolute pain. They don't measure anything like the genuine item and will cost more in tuning time than what its worth

Nistune Z32 AFM forums link

Declan from Garage 7 shows on his website the internal differences of the Z32 AFM copy and changes in mapping here

    • 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
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
    • Power is fed to the ECU when the ignition switch is switched to IGN, at terminal 58. That same wire also connects to the ECCS relay to provide both the coil power and the contact side. When the ECU sees power at 58 it switches 16 to earth, which pulls the ECCS relay on, which feeds main power into the ECU and also to a bunch of other things. None of this is directly involved in the fuel pump - it just has to happen first. The ECU will pull terminal 18 to earth when it wants the fuel pump to run. This allows the fuel pump relay to pull in, which switches power on into the rest of the fuel pump control equipment. The fuel pump control regulator is controlled from terminal 104 on the ECU and is switched high or low depending on whether the ECU thinks the pump needs to run high or low. (I don't know which way around that is, and it really doesn't matter right now). The fuel pump control reg is really just a resistor that controls how the power through the pump goes to earth. Either straight to earth, or via the resistor. This part doesn't matter much to us today. The power to the fuel pump relay comes from one of the switched wires from the IGN switch and fusebox that is not shown off to the left of this page. That power runs the fuel pump relay coil and a number of other engine peripherals. Those peripherals don't really matter. All that matters is that there should be power available at the relay when the key is in the right position. At least - I think it's switched. If it's not switched, then power will be there all the time. Either way, if you don't have power there when you need it (ie, key on) then it won't work. The input-output switching side of the relay gains its power from a line similar (but not the same as) the one that feeds the ECU. SO I presume that is switched. Again, if there is not power there when you need it, then you have to look upstream. And... the upshot of all that? There is no "ground" at the fuel pump relay. Where you say: and say that pin 1 Black/Pink is ground, that is not true. The ECU trigger is AF73, is black/pink, and is the "ground". When the ECU says it is. The Blue/White wire is the "constant" 12V to power the relay's coil. And when I say "constant", I mean it may well only be on when the key is on. As I said above. So, when the ECU says not to be running the pump (which is any time after about 3s of switching on, with no crank signal or engine speed yet), then you should see 12V at both 1 and 2. Because the 12V will be all the way up to the ECU terminal 18, waiting to be switched to ground. When the ECU switches the fuel pump on, then AF73 should go to ~0V, having been switched to ground and the voltage drop now occurring over the relay coil. 3 & 5 are easy. 5 is the other "constant" 12V, that may or may not be constant but will very much want to be there when the key is on. Same as above. 3 goes to the pump. There should never be 12V visible at 3 unless the relay is pulled in. As to where the immobiliser might have been spliced into all this.... It will either have to be on wire AF70 or AF71, whichever is most accessible near the alarm. Given that all those wires run from the engine bay fusebox or the ECU, via the driver's area to the rear of the car, it could really be either. AF70 will be the same colour from the appropriate fuse all the way to the pump. If it has been cut and is dangling, you should be able to see that  in that area somewhere. Same with AF71.   You really should be able to force the pump to run. Just jump 12V onto AF72 and it should go. That will prove that the pump itself is willing to go along with you when you sort out the upstream. You really should be able to force the fuel pump relay on. Just short AF73 to earth when the key is on. If the pump runs, then the relay is fine, and all the power up to both inputs on the relay is fine. If it doesn't run (and given that you checked the relay itself actually works) then one or both of AF70 and AF71 are not bringing power to the game.
