no WB, I don't know what the fueling was actually like, but went well regardless, no knocking unlike 98

narrow band showed it was tad rich in the 9.8 areas but still close enough for BLM to correct for, beyond that the NB cant tell you much.

im more interested to see if the narrowband went leaner readings as the injectors maxed.

i should have a partial log. my logs kept dropping out, larger I found I have a faulty USB port on the laptop.
ill take a look and post it up later.

Do you have to set the 0 and 5V scalars differently on E85?
here is a log anyway. Looks like it was bit too rich and it never ran out of fuel even at full noise and 100% DC.
So yes, you can run a stock V6 no probs.

if your talking about wideband, then yes, you need to set them to the min/max for your widebands analog output settings of E85.

how do you know what they should be? 14point7 don't list anything other than petrol 0-5v AFRs
can you work it out based on the spread sheet to PM little while ago?

yes you can figure it out.... convert the petrol AFR's to lambda first, then convert that to E85 AFR, then use those numbers.
eg: most of them are 0v = 10 and 5v = 20 AFR
so 20 / 14.7 = 1.36 lambda
10 / 14.7 = 0.68 lambda
stoich of E85 is 9.8526
so 0.68 x 9.8526 = 6.699768
1.36 x 9.8526 = 13.399536
so the values you use for the range are 0v = 6.7 5v = 13.4
