Do I Need A Z32 Afm?

I need to buy a new afm now as the one I have now is playing up.

I'm about to fit a gt2530 turbo, pfc, gtr injectors and 040 pump to my r32gtst, however not till after christmas.

I'm chasing 200 rwkw give or take.

It seems pointless to me to replace the afm with a stocky but some people seem to make this power without changing to a z32 afm.

If I buy a z32 afm now and fit the pfc and select the z32 option will the map run the car satisfactorily without an immediate tune?

Stock AFM is fine, but the Z32 AFM is a better unit for tunability and future proofing.

If your stock AFM wasn't playing up I'd say leave it for your 200rwkW target (or until it becomes a restriction), but I'm going to take a guess and say you're not going to want to live with "only" 200rwkW forever. At which point, your replacement stock AFM is going to be a waste.

And its not like the car is going to perform worse with the Z32 AFM at your current level of tune because it can't cope with the lower airflow, so there's no technical negative to it.

Be a man.

Do the right thing.

I've read a lot of threads on this.

My conclusion is that either afm would work for 200rwkw.

I'd probably buy a z32 afm later but have been forced to decide now due to the stocky failing.

The main point of my thread is to find out how well the pfc will function with the z32 afm on it's base map until I can fit my new turbo and 444cc injectors and have it fully tuned.

U may as well get a Z32 meter coz it really wont hurt especially with a pfc, however running a HKS GT2530 u dont really need a pfc, if u upgrade your fuel pump and get a HKS FCD and maybe a fuel regulator to adjust fuel pressure you should be good to around 220-230kw at the rear with your standard injectors, u can get ur ecu remapped and your rev limiter changed to 8200rpm and u should have one sweet ride

      Old Son, did you re-use the Holden ABS in the new shell or try a different module?

      Another little story of weird shit happening

      Yeah, nah. I had the actuator rod off it today. The arm will not move at all. Neither out, nor in. Yeah, you'd think so, but I've been thinking about that. Even when the actuator rod fell all the way off at the beginning of this saga, it would build more boost and faster in lower gears than it would in higher gears, and you'd think that that was the opposite of what should happen. But I strongly suspect that there is a thing with the gearing getting the revs to rise faster, that there must be some transient effect with the gas flow rate rising quickly, that you don't get with the more steady state case of the higher gears. Keep in mind - the gate is not shut in either of my weirdnesses. So things are not "normal". We normally think about a turbo spooling up (below the wastegate target) with the gate shut. I have all sorts of mental models running now where the gate is a little bit open, and having it stuck open allowing gas out while it should be going through the turbine has all sorts of weird effects (in these mental models). I'm thinking in the higher gears, the ex mani pressure builds to the point where enough gases spill out the wastegate to just prevent the pressure rising much more at all, or just creeping up, all the whole the revs are increasing and getting closer to the point where a gear shift becomes necessary.

      Is it possibly wastegate actuator itself is sticking, or even the rod to flapper? Otherwise I reckon things are getting a bit rusty/worn   Also odd it won't boost in 3rd to 5th, but will in 1st, I'd expect the other way around with it slightly open as there's more time on your way to redline for it to spin up

      Looking for a part number for this part here

      Did some FASTing ...got the impression that the actual part# was a moot point ; seems all of these hardlines for coolant are discontinued/NLA... like, I take it you're after the hardline that bolts onto to the manifold...that's NLA according to amayama & nengun .... ...just to clear up some confusion, they typically mounted the AAC valve to the intake manifold somewhere near a coolant passage, so the body of the valve heats up & holds it open when engine's up to temp - no coolant flows through the valve, it's a mechanical, thermal connection.
