Mooney Fuel quality relay???

Hi guys!
Just wanted to ask something I read in another 33 forum. Actually the author of the thread owns a 33 1.7 16v ie.
In his post, he mentions something like this:
- The fuel quality relay has already been removed and has been bridge wired to give max advance.

What is that? Does my 33 IMOLA 1.4ie that runs the Weber Mareli IAW system has A FUEL QUALITY RELAY, or they were not equipped with such a thingy?!?

Alfa 33 1.7 16v

Not sure about your model but the 16v has 3 different coloured relay type dongles, red=95 ron no O2 sensor, yellow=95 ron with O2 sensor, blue=91 ron with O2 sensor, no dongle=97 ron no O2 sensor.
It adjust the ignition curve to take avantage of better ron fuel and reduces ignition to prevent pinking when using lower grade ron fuel.

Have a look here http://www.sanderfamily.com/ (goto ALFA THINGS / IGNITION ADVANCE on the left)
