Step 31 - Plug all the connectors back into the ECU
Step 32 - Hook your battery up once again
Step 33 - Put your ignition to the ON position - DO NOT START THE CAR! You need to set the SAFC up first
Step 34 - Your SAFC should light up. If not, check all connections are OK. Make sure you have no shorts, bad joints etc
Step 35 - A menu should appear with 3 items on it. You can move up and down by turning the big dial on the right (although it's abit backwards, you turn anticlockwise to go down and clockwise to go up through the lists). The centre button should be moved to the right to enter a submenu and the left to go back
Step 36 - Rotate down to the etc menu item
Step 37 - Push the centre button to the right to enter the menu
Step 38 - We want to look at the sensor type so go right again
Step 39 - Move up and down through the list (use the dial from step 36 or the button as shown) until you find Karmann (for karmann vortex style AFMs) and then push the centre joystick thingy to the left to return to the previous menu. Alternatively, do it the hard way and press the centre button (picture 1) then choose 'PR' for previous by moving the joystick left then pressing the centre button again (picture 2)
Step 40 - Next, rotate the dial or push the joystick down to 'Car Select'
Step 41 - Set cylinder to 6 by moving the joystick up and down then move it right to go to the arrow. The arrow can point up, down or have two ** characters. You want it as shown which means the throttle position sensor (TPS) will output between 0 and 1 volt when shut and 3 to 5 volts when at wide open throttle (WOT).
At this stage there is mention in the manual of self learning the throttle opening but I'm a little unclear as to what they mean. It seemed like you have to hold the throttle closed for 10 seconds then at WOT for 10 seconds so I did this. Hopefully someone will shed some light on this?
Step 42 - Back to the previous menu, then scroll down to Sensor Chk
Step 43 - You should see something like this. Check that pressing the accelerator changes the value of Thrt (Throttle) accordingly. If not, you may need to rewire the SAFC so that the grey wire is one position to the right (i.e. instead of being third from the right on the connector it is second from the right). If you see the throttle going up to 3 Volts or more (picture 2) then you are fine and move on to step 44
Step 44 - Turn the ignition off to store the values
Step 45 - Pop back to the first menu with 3 items on and select item 2 then scroll down to Knk Set and you should see the following screen
Step 46 - Start the engine and you should be able to set the knock values. Mine were already at the values shown (from a previous install) so I left them alone.
Step 47 - At this point I reached the limit of my ability so I hooked the original bullet connectors back together so that the SAFC was making no modification to the fuelling and took it to a rolling road to get them to tune it
