2006 expedition 5.4l e85

I do not, what are you looking for specifically ? Whats all done to it?

[efloth]

It is completely stock. Just want to change stoich AFR to 10:1, add some startup enrichment, add crank pw, and max out the bdl knock table for e85. would also be nice to leave wot at stoich and reduce hego amplitude for efficiency. Is there load based enrichment on these newer strats? it is a 12 passenger van that never tows anything. e85 is half the cost of 87 gasoline here so worth making the switch. This is my first rodeo with PPC architecture so thanks for whatever direction you can provide.

[decipha]

why would leaving wot at stoich and reducing hego amplitude be efficient ?

[efloth]

Just from experience playing around with those parameters on my 4.9. Of course it could be because i swapped in some 80s though.

Finally pulled the tune from the 06 expo.

Awesome, thanks man. I will try this out today most likely. Forgive my ignorance but the first 0xffff section of this new file is blank. What is all of that junk in the factory bin if not needed?

[efloth]

Uploaded the tune today. Worked out perfectly so thanks again. I have started building an XDF for the 05 E350. I will start another thread for that.

decipha mate, how did you land on 65 psi with that fuel flow number in the first place, was it a dyno job or just trial and error until teh wot fuel stopped going lean, cos i can't be arsed guessing at it. and did you definately have to tweak the deltap multiplier on a stock van like that or did it come out about right first go, anyway just my two pennies worth lol

decipha how did you settle on .83 lambda at wot, mate?
