All the information you need to convert your Edge to a Gryphon is in their website, right here:
http://dygytalworld.ehost-services13...p/Upgrade.html As you can see, they would like Canadian customers to call first for specific instructions.
However, DO read the general instructions on that page and click on the "Gasoline" button for the upgrade form.
It's all pretty simple, really. I converted an Edge to a Gryphon back when they were just getting started and couldn't be happier.
One thing that may not be clear - if your fuel is octane rated using the Research Octane Number (RON) only, you will be filling from pumps having only 91 and 95 octane gas I think. That is equivalent to our (R + M)/2 octane ratings of 87 and 91. Make sure Bill knows if this is the case, and, DO put as much "detail" into the optional field at the end of the order form as you can. The more Bill understands your driving goals, the happier you will be.
