extra MFA functions?

[chrishill 0]

While out for a spin with chrisVR6NOS yesterday we were trying to get my MFA to show the extra info, but couldnt get it to work! how do you do it on a 1.8 16v?

Only method I know is for the G60 -

 

1. Start Engine

 

2. Move the MFA selector to "2"

 

3. Press and hold the MFA end button (keep holding)

 

4. Stop engine

 

5. Start engine

 

6. Release the MFA end button.

 

As you press the MFA button it will take you through the extra features.

 

I can't remember if my old Scirocco (similar K-Jetronic injection system as the 1.8-16v) had the extra MFA features or not.

The extra info is used most commonly for checking the boost pressure on G60's but it shows other things too.

Just remembered I had some stuff on this hidden somewhere :)

 

For pre 1992 C's the extra MFA functions are:

 

MFA switch, position 1:

1: Engine map code.

2: Country code.

3: Speedo drive ratio.

4: Upper RPM limiter.

5: Lower RPM limiter.

6: Deceleration fuel shutof pressure.

7: Segment test.

 

MFA switch, position2:

1: Test sum of programmed bytes

2: Intake manifold vacuum/pressure.

3: Engine RPM.

4: Momentary fuel consumption.

5: Signal from speed sensor.

6: Oil temp.

7: Ambient temp.

 

Hope its of use to someone!!!!!
