Questions for you Edge Evo owners, On the performance setting 3 atleast thats what I have been reading, I think ! Can you set the evo to run at level 3 which it calls for 93 octane and then go back and adjust/subtract the timing to fit 87 octane and still run decent. I'm not sure if you can adjust the timing or not but I thought that is what I have seen. Let me know, Thanks

 

you can, but its a real pain in the A**.

Its almost easier to just run in level 2.

BTW level 3 only requires 91 octane.

 

Yes you can, and I don't find it to be much of a fuss. As long as you load the "previous settings" first, you shouldn't have to make any adjustments if you're still using high octane gas.
As was already mentioned, level 3 calls for 91 octane. If you change to 87 octane and then click on previous settings, the only thing you'll have to adjust is the timing, and perhaps fuel at WOT.
