AFM Tuning

These photos will show how to adjust the clockspring in the 1.6 AFM. I pretty much went overboard with safety.
In reality, you don't have to loosen the retaining arm screw, you can just stick your finger in there, move the spring stop and move the clockspring by hand. I found it was more controlled to do it with the screwdrivers.

Tools:
2 phillips head screwdrivers
exacto knife
Flat head screwdriver


NOTES
*This should be ideally done with either a wideband sensor and data aquisition or on a dyno.
*Be careful not to get too overzealous with tuning, too lean and the motor goes kaboom.
*This is not the same as AFM tuning from most SM suppliers. They do fancy stuff with laser etching, etc. But it gets you closer.
