Anyone add a gallon or two e85 to 93 octane to lessen or eliminate any knock ? Especially running a strong 93 octane tune it could only be beneficial id imagine . Winter blend gas im sure is less potent as well.

Yes, LOTs of guys do it. A gallon to two TOPs, however, you may have fuel pressure issues depending on the tune.

Best bet would be to ask your tuner, based on your logs, if a couple gallons are safe.

Yep^ ask your tuner. They know best on what your tune is doing.

Not pointing any fingers, wish it was that easy guys . Reason why I'm resorting to the forum for some answers. Anyone who can look at my logs and help would be appreciated.

How much knock are you seeing?  What does your OAR settle to?  Tried different stations/brands?  Many resort to a lower octane tune with higher octane fillups for the winter.  Staying away from MORE ethanol during this time is recommended.

If tuned:  Take note of the strategy code as you return to stock (including 3 bar MAP to 2 bar MAP) -> take car in & get it serviced -> check strategy code when you get car back -> have tuner update your tune if the strategy code has changed -> reload tune -> ENJOY!

Below -1.00 often a couple different stations. Ethanol less then 20% won't hurt anything in winter. They say not too much ethanol in winter for startup issue . Drove my s550 mustang with flex fuel tune 40 % it was good anything higher it was hard at starting sometimes

I can also check out your logs if you want.

Should be able to attach the logs to your posts also to get multiple sets of eyes on it, if you want.  Or you can get a google drive/dropbox account, upload there and plant a link here :)

I would definitely check your data logs and ask your tuner first but typically we see on a car with a 93 tune and some bolt ons that fuel pressure starts to drop around 70 degrees and the colder it gets the more the fuel system will struggle, if you had an accommodating mod like a HPFP then a couple gallons mixed would be no problem, as you could do an E30 tune on this setup

If you're not too certain on the proper mixture,ratio just add a bottle of Heet preferably the (yellow bottle) @ every fill up especially during the cold winter months.  Z

18SHO was kind enough to send me a couple logs, he is good to go. His logs actually show near perfect fuel pressure 2000+psi.. and almost no knock.. less than +1KR (.8 iirc) at worst.

I think it was a polish notation issue.. SCT reports adding spark with negative knock values and pulling spark with positive KR values..

18SHO tune looks very well done for the fuel he is running.

Near perfect? LOL I love this log. The 3rd gear pull shows perfectly flat fuel pressure and this is a sustained commanded boost of 14 psi from 2700rpm to redline. Boost is green, nice and flat through the entire rev range.

And in the multi gear pull fuel pressure is basically unaffected even with boost spikes of 16.77 psi....And some of the very small dipping that you see is not due to too much boost or the fuel system being pushed but rather from the increased fuel demand and how quickly the boost is ramping...I've seen the stock tune do this..I've said this before but the fuel system stock is pretty strong but hates to be ramped on

When you get boost spikes the fuel system has a hard time keeping up due to reaction time and not due to flow limitations..Control the spike then you can control the pressure dip....With in reason or barring a mechanical problem.

ALso this was in 50 degree temps with IAT's being lower than 100 so I thought this looked decent.
