Is anyone using their edge with only 87 octane for towing, performance and fuel economy? What settings did you change? Any issues?

 

Don't know why you would even consider running Level 3 with 87. When I run Level 3 with 93, I get about 12% better gas mileage, than on Level 2 with 87. That pays for the difference in cost. I run Level 2 aruond town for the low end torque and run Level 3 with 93 on trips for the higher end responsiveness. Obviously, if you were running Level 3 with 87, you would need to back the timing off 2 points.

 

I run level 2 on 87 octane but I set the timing at -1 to eliminate high RPM, high load ping. I have no use for level 3.

 

elevation could factor into his timing change also, I think it's like +.5 for every 2500ft above sea level, so depending where he is he could have to back it off more or less, I know I ran alot higher timing (+1.5 L3 w/ 91) when I lived in golden as opposed to montana (+.5 L3 w/ 91)

 

or you could leave the timing alone and increase WOT fuel to 1.6 and you will get more performance, better milage and no ping. When I first went to level 2 and did a 0-60 test I had a pretty good detonation. That was from lean conditions. Not timing. I bumped the WOT fuel to 1.6 and have had no problems since. And yes, bumping WOT fuel increases fuel before WOT. Not at cruise or partial throttle.

 

Thanks, I'll try that.

 

That's exactly what I run . Truck pings like a SOB on level 2 with a load without bumping the timing down -1.

 

Chris, you think increasing WOT fuel to 1.6 is better than bumping the timing down -1.0 when using 87 octane on level 2.

 

Nope, that doesn't work! Tried it and it pings like always under heavy load. Put it back to 1.1 and put the timing back to -1 and works great, no ping.

 

When you guys say increat wot to 1.6 you mean 160 right. When im done my custom settings on level 2 mine starts at 120 and i increase to 150, havent tried 160 yet. Also when you speak about detenation and ping, im not sure how to listen for that, I know that the 97-03 2v engines always have a light knock to them which is supposed to be the cam phasers or something.I recent went through 2 tanks of 89 octane on level 2 with customizing wot to 150 and wot shifts to 5200 1-3 and 4800 3-4 and bumped the timing up to +1.0 and shift firmness +4 +4 +2 and along with all my mods i really felt the truck ran slow and doggie.I just switched back to 87 and only adjusted wot to 150 and shift firmness +2 +2 +1 and tire size and gear ratio and it feels better. The main difference i noticed between the two was now the truck sounds smoother and quiet as opposed to a bit raspy as it was when the timming was bumped up 1 notch. Any help would be appreciated
