HOW TO: Access the MFA Secret menu

[rubjonny]

No! I demand you move it back this instant!! 

[Mr Blue]

The secret menu is ideal for setting your idle speed 

I always useit to set mine

[Deefadog]

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?

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???

[rubjonny]

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?

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.

I have managed to find an old copy of the website, I'll update when I'm not drunk and tired
