Title: HOW TO: Access the MFA Secret menu
Post by: mk3miniturbo on 28 September 2005, 14:59: HI,
quick thread as I am very intrigued. I know how to get into the secret menu on a mk2 golf gti MFA.
But does anybody know what all the options are. The only one I know of is the digital speed reading which is the second along. Have searched loads on the internet but cant find anything.
Are all the others CO2 readings and fuel to air?

Please help I fear I may not sleep LOL :smiley:

Thankyou all

position 1:
Default: Engine code
1: Land code
2: Speedometer
3: Upper rev limitter
4: Lower rev limitter
5: Decelaration fuel pressure
6: Display test

MFA switch on position 2:
Default: Test programm of programmed bytes (checksum)
1: Intake Vacuum
2: Digital rev counter
3: Fuel usage (like normal)
4: Signal from speedo sensor
5: Oil temperature (like default)
6: Ambient temperature (like default)

Edit: See my last post on page 2 for an alternate list I got from another website!

Post by: rubjonny on 28 September 2005, 15:29: Whoa now boy what makes you think I would know these things :grin:

Sorry I haven't a clue how you would do this, when you say digital miles which one were you refering to?

Post by: ANDY597 on 28 September 2005, 15:31: Sorry Rubj, you just sparked a mod idea in me.

If the mfa is capable of showing Speedometer as digital in that MFA menu you just rattled off so easily.

I was thinking to myself it would be cool to display this all the time with an aux gauge.

Post by: Chris_D on 28 September 2005, 15:31: this thread should be made sticky, never new there was a secret menu!
Title: Re: MFA Secret menu PLEASE HELP
Post by: rubjonny on 28 September 2005, 15:43: Hmm, no idea how to get that but I assume it is read from the little sensor screwed into the back of the speedo, if you knew someone who is a whizz with electronics and decoding signals it shouldn't be too dificult.

Plus there is the digitial speedo sender that was fitted to the MK3, but the troble with that is it goes where the normal speedo cable goes so you would loose the speedo drive.

Post by: Mr Blue on 28 September 2005, 19:23: The secret menu is ideal for setting your idle speed :smiley:

I always useit to set mine
Title: Re: HOW TO: Access the MFA Secret menu
Post by: Deefadog on 29 September 2005, 08:30: Yeah it's a very accurate for setting the idle!

Also - Decelaration fuel pressure & Intake Vacuum

Any ideas what the these values should read on a properlly set up valver?

Post by: tobz. on 29 September 2005, 09:21: Tried this out, pretty cool, I like the fact that the mpg reading is instantaneous rather than an average. However the speedometer setting doesn't seem to work on mine it just displays 955 all the time??? This was the setting I was most interested in as my momo wheel obstructs my view of the speedo. Does this setting work for everyone else???

Post by: rubjonny on 29 September 2005, 09:37: on another site it lists it as 'rpm engine' and says it shows the actual rpm of the engine? Could it mean the idle rpm?
Title: Re: HOW TO: Access the MFA Secret menu
Post by: wellfan on 29 September 2005, 22:21: Please explain. What is 'Land Code' and what do the rest of the readings indicate. I have managed to access the secret menu but it means f... all to me.
