Im thinking of purchasing one of these
http://www.kufatec.de/shop/product_info.php/language/en/info/p1329_E-MFA-DIS-Add-On---Display-Boost--Oil--Battery.html/XTCsid/5ac96dd026d5a774e151a4beb293d17f
Think it will be a useful addition for displaying extra values like Oil Temp and battery voltage without resorting to external gauges.
However before I do does anyone know if it will still be compatible with my car as I now have an aftermarket Alpine double din headunit installed?
I do have the full highline display but no cruise control(yet! :wink:) or Multi Function Steering Wheel.
I could do with your advice before shelling out!
-
i ordered FIS from polarteam,like this e-mfa butt it can be used with oem BT ,its compatible with every mk5 using highline display
-
And does it give actual boost? Ive seen this on alexperkins car and it is a cool little mod!
Which page does it use on the highline? Does it replace the satnav page?

It uses the telephone page, so you cant use it if you have a phone kit but it comes as part of the Fiscon phone kits. Should work with the aftermarket headunit as it doesnt use the head unit at all it just uses the headunit wiring to gain access to the canbus system and as a power source.
It doesnt show boost on TFSI engine unfortunately think its only good for diesels otherwise it would be a useful tool.

It wont give boost. As said its only good for diesel engines
Its very useful, though its interesting as the speed is often a few mph out when you get to higher speed which suggests the clocks are somewhat inaccurate!
-
Ive noticed my speedo is out at higher speed with comparison to my TomTom GPS speed display.
Im guessing the GPS is more accurate. But gonna get one of these E-MFA addons ordered.
I dont think you can have too much info about whats going on in the engine.
Got a boost gauge installed already so not too worried it doesnt display that info. :driver:
-
Aye that what I mean - the clocks will show 90, but the EMFA will show like 82/83 so im not sure where it reads its speed from
I get Oil Temp, Battery Voltage, RPM and Water Temp - all very useful as you know when you can give it some beans safely!
-
The clocks have a built in inaccuracy, but the satnav and the E MFA use the dead reckoning figure sent across the canbus system, if you have the RNS and go into the diagnostic menu you can see the dead reckoning figure, you can also alter the factor on your speedo to make the needle more accurate.
The Polar FIS one looks interesting as it uses the telematics highline screen rather than the telephone screen, it however goes in-line with the canbus so not as easy to fit! Also no uk supply only in Spain at the moment. They do have a list of ECU's that supply boost across canbus which would be the same as the Fiscon unit.
-
So that said, the EMFA is a more accurate speed than the clocks?
-
Yeah its using the proper road speed as calculated by the ECU the ECU signal in the clocks has a wiggle factor added so it over reads.
-
I'm just about to order one of these for myself but for my 1.9 TDI. I'm hoping the boost works on it as I want to avoid the cost/install of a gauge!
-
Boost over can works with these ecu's
COMPATIBLE WITH ALL ECU
- 03C 906 056 BG (MED9.5.10)
- CF 906 021 03G
- 03G 906 021 KH
- 906 022 S 03L
- 06J 906 026 AR (MED17.5)
- 03C 906 032 N (MARK ONLY PRESSURE? N WHEN THE TURBO EST? UP)
ECU NOT COMPATIBLE WITH PRESSURE? N OF TURBO
- 1Z0 907 115 A
- 1K0 907 115 J
- 1K0 907 115 L
- HB 906 018 03G
- 3C0 907 115 Q
from spanish so excuse the wording

The E-MFA is more accurate than my Becker GPS. I bet it's even more accurate than any commercial GPS.
We compared it several times with a Performance Box and the E-MFA was very close to it. Much more
close than the Becker GPS.
The reason: standard GPS only have 1 Hz, the Performance Box has 10 Hz and the E-MFA detects the
wheel speed.
I don't want to miss the easy to read and correct speed, voltage, oil temp and water temp anymore.
I'm very happy with it. The most satisfying item of my car. :happy2:

I have always wanted this as well, but due to having OEM bluetooth havent been able too so the one using the telematic screen is of interest, doesnt state if it shows the corrected speed unfortunately.
Dario do you have any pictures or video of yours working and functions it can display for example the corrected speed? Also which supplier did you use?
-
Richn83, I presume that list is from the Polar one rather than kufatec? I wonder if there's a difference in compatible ecu's between them. Mine is SW: 03G 906 021 PM HW: 03G 906 021 AN.
which by looking at your post means it's a no go for boost :(
-
Most diesels apparently work with the kufatec variant
-
Some companies like TurboPerformance in Germany do modifications to the engine ECU
to deliver boost pressure to CAN bus. So it's possible. I don't really need it though.
So that said, the EMFA is a more accurate speed than the clocks?
Aye that what I mean - the clocks will show 90, but the EMFA will show like 82/83 so im not sure where it reads its speed from
The E-MFA displays the CAN speed. The CAN speed is the real speed only affected by
(small) tolerances caused by slightly different tyre circumferences.
The E-MFA is more accurate than my Becker GPS. I bet it's even more accurate than any commercial GPS.

In reality the E-MFA is much more accurate than the pseudo-accurate satelite navigations for car use.
Military GPS uses at least 10 Hz and more exact navigation data material. Commercial GPS can not be true !!

Just found this amazing product. I think its the opposite way round for boost readings, works with GTI and not TDI!

Looks awesome!

That one uses the OBDII port not the canbus, so you need to have it connected constantly to you port down by the pedals.
The issue with the boost is that either system uses can bus system for the data the ECU doesnt send it out over the can bus it cant be read so both systems will be affected by the same limitations so I would take the list as for both unless one of them comes up with a work around to get the info over the canbus.

hy sorry didnt receive mine yet ,ordered it on monday ,from the polar team page ,when it comes i will take pictures and video ,there are a few vids on YT demonstrating the fis in skoda octavia

Yeah I did a bit of reading about it. From what I understand they basically have an algorithm that uses the outputs from the odbII to get the boost value. If it works fine for TDI id prefer that tbh over the kufatec e-mfa

I was looking into this as an upgrade following the step to OEM bluetooth and thought against it due to the incompatibilities i'd read about, however, it now turns out that the fiscon bluetooth kits have the E-MFA together with the bluetooth in one little box and i think i'll be heading down that route!
just a heads up, because up until recently i was unaware of the included features (the E-MFA) of the fiscon bluetooth!

If you have already installed OEM bleutooth then the polar FIS will work but the kufatec uses the telephone screen, for that reason (already have the OEM phone) will be going down the Polar route once the highline is retro fitted. Also seems they have plans for further development of the unit and you can program buttons to skip tracks and volume adjustment while viewing the additional information.
