Miller maf conversion

[porschetub]

Anyone fitted one or is it not ready for sale?,wonder why the dyno test doesnt work on there website,keen on feedback thanks

[Gawernator]

It's finally out?

[porschetub]

Tell me more

[Gawernator]

Apparently nobody cares since Rogue Tuning released a MAF

[RedBaron]

+1 on Rogue Tuning. I can't wait until he comes out with an S2 version.

[porschetub]

True but why the price? can't work out the worth of this system ,a good chips worth maybe 5 hp in the @ higher rpm and is rest that is gained by the maf conversion isn't a lot more so is it about more power thru the total rpm rangenot it the position to send my ecu half way round the world for the chip conversion.
Thats why the Miller conversion is more suitable to me,my motor is already running the 28 pin chip ecu,please if I sound a bit blond here but I need some REAL info,cheers.

[Gawernator]

Yes more power throughout the curve not just peak power

[porschetub]

Are you running one?

If you have a 28pin ECU - then there is no need to send me your ECU...

Here is the difference between stock and the NA-Tune + cam-key on a conservative dyno:



No chip-only solution will even get close to that kind of % gain across the board.

The cost covers the fact that you replace your dying AFM with new solid-state hardware, that doesn't wear-out. It is also a custom-molded unit which directly bolts-in-place of the AFM, and plugs into the factory wiring.

Furthermore, having the NA-Tune opens-up the door for connecting the Logger and DME Tuner. The logger has been invaluable for troubleshooting in my own use - and provides the single most powerful tool for diagnostics available for the 944.

I've tried to provide as much real info as possible... Back-to-back dyno plots, identifying what adds hp/tq and doesn't, all instructions readily available on the website, ect. I am at a loss for what more 'real info' you could want.

Joshua, do you have the cam key available on the web site?

For those of us just checking this out for the first time, what exactly is a "cam key", and what cost would I be into (total) for this system in my 85.5 with magnaflow stainless exhaust ?

Yes, it is there as an option for the NA-Tune.

A cam-key, is an offset key which replaces the normal one on the camshaft. The key is what aligns the camshaft and cam-gear. The offset key we use to advance the camshaft relative to the cam-gear - resulting in a change in camshaft timing. This is a physical (valve-event) timing change, and is different (not related) to an ignition timing change.
The NA-Tune is $500. The cam-key is an additional $20. Your 85.5 has the late DME, but is 24pin. You would either need to send it to me to convert to 28pin, or convert it yourself. The DME conversion service is $50. So, your cost would be $500 to $570, plus shipping.
Here is a picture of the actual key:

Hey, that looks exactly like the ones I used to use on my 5 HP Briggs & Stratton Raptor racing motor on my dirt racing kart. How hard is it to install the key......just to remove the sprocket ?

Yep, remove cam-gear, remove the old cam-key, install the new one and put back on the cam-gear. Then put back on the timing belt, and time the motor like normal.
A little bit of filing will help the key installation.

Joshua,thanks for the info,yes the horsepower curve is very differant than I thought,chip conversions seem the make power above the normal driving rev range and I can't see the worth of that except maybe improved driveability (claimed by makers?).
The 8V motor has never been called frugal on gas have you noticed any improvement in that area?,has the 2.7 shown higher gains over the 2.5 ?
Thanks for your time.

During part-throttle, we actually see even higher percentage gains! This is because the factory AFM is still partially closed, producing quite a restriction. Gains up to 20% are common in the part-throttle range.

For high-way driving I have noticed a slight increase in mpg. Around town seems to be very similar (though I really don't drive for economy!).

The 2.7 should have similar %gains as the 2.5. Perhaps a little more due to the bigger engine being choked by the same size factory AFM.

So tempting.... but then I'd lose my awesome FRWilk's chip and have to convert my DME... and my AFM was already rebuilt lol

I'am now more than tempted,Josh is a good salesman and also comes up with the goods ,my motor is low mileage (50,000kms) and runs good so I will be in for more go.
Was going for the Wilks chip but always thought about a MAF conversion ,just needed the info.
I have decat exhaust setup and the later steel exhaust manifolds which must flow better than the cast ones .
I will have to get the funds together soon as my countries dollar is strong,still have to factor in freight and customs duty,thats the killer.

Do you have a setup for an 87 944S?

The DME conversion is not difficult, any local TV repair place should be able to do it (if you don't feel comfortable doing it yourself). I also offer the conversion service if you want to send me your DME. Additionally, the DME conversion is reversible if needed - though I wouldn't bother, if you need to go back to stock, just use a stock 28pin chip.

Thanks for the compliment - though I am definitely a better engineer than salesman!

The 16-valve cars (the S and S2) are coming. I have done the initial software code - next is the proof testing. I have something ahead of the S/S2 kit, but I expect to be working on it more in early May.
