Maxing out AFM on rb25 NEO - whats next?

[Dil-Dog]

I am running a stock Pink labeled NEO Maf with a STOCK Untuned NEO ECU... With the new larger turbo and intake system, i am now getting hard cuts when i am approaching 13 psi as the airflow is too much for the AFM.

I am planning on doing the norm and trying the already well documented Z32 MAF swap by ordering a ISR performance OE replacement from Enjuku Racing.

HOWEVER here is my question....
I have heard and asked some people if it can be done using the stock ecu (obviously i know that i have to repin the plug to the Neo harness) but some people are saying that you HAVE to have a tuneable Ecu/ Piggy back to make it work. even the product description on enjuku racing says you will ecu compatibility tuning to make it work. HOWEVER i heard some others say you can do it with no problem on the stock ecu but i never actually spoke to someone who claims they have with the stock ecu.

I am hoping i can get away with my stock ecu.

Does anyone have experience with the STOCK ECU?

Or... if there is any other options to help get around this, please let me know

Absolutely not. ECU will have no idea what the air flow is if you change the AFM and don't change the voltage to airflow curve in the ECU

The next step is Nistune.

Don't faff about, if you want it to work properly you need to recalibrate the MAF curve.

Okay okay thank you guys for the advice...

i thought so too but i just wanted to make sure. It makes sense though that you will have to tune it with the ECU.

And in all seriousness, don't buy a Z32 AFM. The card type AFMs are infinitely superior.

R35 MAFs are known to be good, just size the tube it's in appropriately for your power goals.

As much as I love Nistune, and also being a dealer/tuner for Nistune - the R34 one is a massive pain in the arse to get right.

The throttle enrichment, the simulated VE table and hitting the last row each time your boost sensor voltage taps out drives everyone nuts. Yeah you can "disable" the R34 MAP sensor, but then you'll notice the load scaling then goes out the window too.

Just go full standalone.
