Holy hell, why so rich? Here is what a proper table might look like:
You will want it just like gasoline Tony. I tune cruise and idle to 14.5ish. Shoot for that and see if you like it.
You account for that difference in the global fuel calculation if I recall.
Yes, the WOT should be 11.0 - 12.0 (which is getting kind of lean). Change the stoich in the fuel tab to 9.8:1 instead of 14.7:1.
When you lean out too much, you do get power but a hella lot of heat also as my exhaust was glowing RED when I ran 12.5-12.9 up top under WOT so try to keep it to 12.0 or just under for safety sake.
Are you on Speed Density Tony?
Well hell.....I am not as good on a MAF as I used to be since I converted all 3 of our DSM's to SD. Sorry man!
Are you on Speed Density Tony? If so, go cruise and let SDAdjust help you get it dialed in. Right click on the log and then click on SDAdjust and apply the table recommended, then do it over and over until you like the way she runs.
Remember to reset your fuel trims in between.
..my bad. Thought 9.8 is where you'd want it for cruise and idle. Thanks Vegas!!
Change the stoich in the fuel tab to 9.8:1 instead of 14.7:1.
Well that is how I tune and it works just fine. Why do you think that option is in link? Just asking.This would be correct If you were looking purely at ethanol afr scale, then stoichiometric of E85 is correct at 9.8. But unfortunately all tuning in DSMLink is in gasoline scale so 14.7 is what you still have to use and stick to.
No, you can't do this. DSMLink only understands gasoline afr scale. If you tried this it would be running pig rich in closed loop. You have to keep it at gasoline stoichiometric of 14.7.
He's referring to the global fuel calculator under the fuel tab. It's only used to calculate your new global when switching to e85.This would be correct If you were looking purely at ethanol afr scale, then stoichiometric of E85 is correct at 9.8. But unfortunately all tuning in DSMLink is in gasoline scale so 14.7 is what you still have to use and stick to.
