Are AEM and Pro-Efi supporting the n54 platform? I was under the impression that neither have any solution for the n54 unless i missed something.

Neither will currently drive Piezoelectric DI as I understand it, no.

Believe PTF will flash tune off the stock DME up until roughly 21 PSI, then after that you will need a standalone (no sense of which one or how it drives the PI) or piggyback to directly control the gates.

This.

Are prices for the fueling system available yet?

Pats is correct. Using a tried and true standalone controller for boost control(with no CANBUS interference) allows us to dial in boost perfectly and provides a fail safe setup. It also allows full port fuel injection control.

What do you think the 750 kit would make flash only at 21 pounds? Given whatever octane and fuel is needed.

Prices are coming soon.

Well I just decided to sell everything I own lmao. I feel like I'm looking at car porn when I open this thread

~550whp give or take on 93. 24psi and 93 is 600whp territory and 30psi on race gas is when it get's wild

[Torgus]

Or a multitude of other products which can control multiple injectors. I was really hoping for something made to work with the n54 DME, not 'use something that can fire injectors'. Like a custom pcb for instance.

AEM should be the least expensive can ptf give us an idea of the cost?

550whp just humming along on pump flash only is winning

Realistically speaking there is no option for a 100% full stand alone DME control option... there is a way we can do it but cost would be impractical. Pricing is still being worked on.

Would there be any benefits to going completely stand alone if money weren't an issue, and what would those benefits be?

ProEFI would be the solution. Last I read Undercover was tackling this issue to control the engine but the stock DME would be retained for electronics like radio, windows, etc.

Control of the DI is all I can think of, which is of course limited. The stock DME does an amazing job. Unlike older platforms I don't see the need for a full stand alone unless in a full race environment even then...

So if you got the 600 whp option and used 93 pump gas only, would you still need the supplemental PI fueling system or not?

You don't need port fuel to fuel a single turbo. It depends on how much power you are trying to make. Help on the low pressure side is a necessity.

Most people wouldn't see a benefit with the exception of completely eliminating post shift flatlining issues with the AT. There are some very unique circumstances that would make using a stand alone necessary. For instance if you just HAD to have a turbo manifold running a single O2 sensor/non-divided collector. Or eliminating the DMFW's and AT torque converter's false misfires while still having misfire detection active.

The N54s injectors can not be driven by a stand alone. Proefi, Motec, AEM etc... have been tried and failed. To make a stand alone work the N54 injectors have to go.

[3000GT MR]

So you could partially slave in a aem ems and splice into sensors necessary to be able to drive 6 injectors to hit a target Afr on top of the factory fuel system? Hmm I like the way it sounds. It's almost heartbreaking to think of a aem ems as a piggy back though. I wonder if boost by gear, 2 step ign, etc would work not being on the bus. Aem ems is a blank canvas with more control than any one single person can fathom. I just hope we'll be able to take advantage of its features

Currently there is only ONE aftermarket ECM that is Direct Injection compatible, and it's the new Motec M142 or M182. This comes with 2 "drawbacks", first be prepared to spend Motec money -- $5k just for the ECM, then you need to add in a wiring harness, the necessary/recommend sensors, AND a tuner fee from someone who is approved to tune the Motec M1xx product line (like John Reed Racing, who tunes the UGR TT-Lambos = $$$$$$). ALSO, expect to lose CANBUS integration = No more Gauges, Radio/NAV, Bluetooth, Keyless Entry, etc etc etc. Likely means you're gonna need a Digital Display; aka you've gone full race car.


ProEFI, AEM & Syvecs all will eventually offer Direct Injection support since the automotive community is moving that way -- Most BMWs (specifically M cars), the Corvette, the 997.2/991+ Porsche Turbos, Audi, etc etc. If you want to wait on that, it'll obviously be a superior tuning platform than a stock ECU (especially with all the extra bits like FlexFuel, AntiLag, etc), but until then PTF has proven on its race car that the stock ECU is very capable of doing the job reliably.

Unfortunately, even the latest and greatest MOTEC stand alone isn't up to the task for the N54. We tried it.

[SteveAZ]

I was talking to a tuner the other day that commented on how incredibly fast the N54 DME was and some of the tricks they had to use with aftermarket ECM's on other platforms.

Is this the case in your guys' experience?
