I would get your debit card, put at least another 5 gallons in and drive it. Give it 20 miles or so, then look at your real time diagnostics.

LT Fuel trims are still negative. I've driven 125 miles or so on E85 now.
25 miles or so - https://datazap.me/u/narfalicious/e851?log=0&data=1
more than 125 miles - https://datazap.me/u/narfalicious/e8502?log=0&data=1

fuel trims loog a little negative but that's normal on first tank of E85 due residual petrol




the logging of some parrameters is incorrect, assume your on older v2 tune.


if you use V4 tune then logging will be correct

is there anyway to see if the oil in my car is suited to run E85? i've done alot of research trying to find information on the oil that was put into my car when it got serviced recently (Valvoline Synpower 0W20) its not really mentioned anywhere on the internet and it mentions E85 once on the PI sheet but im not sure its really suited

Thanks in advance

If its rated SN or GF5 it will be E85 compatable

Yes thats normal during overun with zero throttle injectprs are turned off so afr goes to max lean reading of sensor in this case 20


See ECU logging link below

Mixing

I've got just openflash tablet on stock car and wanna try e85. No flex fuel.

I've found a shop in canada that sells e100. To get e85 can I just fill up with e100 and then 93 pump gas on my car? Appropriate volume of course.

Does it mix on it's own or do I have to mix it externally out of the car?

should work id probably mix it to about E70-e80 if on a standard oft tune as that's about the middle of the operating range

Afr and commanded afr should be closecinder full throttle yes you are running about 8% richer than commanded afr. Lkely needs some maf scaling

im pretty new to this tuning thing, but from what I read in your OFT threads, steve. That MAF scaling is driving around at low rpm and steady throttle correct?
what im trying to do is let my ecu learn the trims better correct?

No maf scaling requires collection of data and then recalibraringvthe mas aor flow sensor tables in tune to correct the fueling error

Thanks though steve.
