Just wondering if people are running lower octane tunes for the winter or not. I decided to bump down to 91 to be safe for the winter blends but not sure if it is really necessary or not

Depends on where you live climate wise and how the winter fuel blends impact your car...
I have fantastic fuel all year round in Virginia so I keep the 93 octane tune all year round.
I do have tunes that are not as aggressive in the event I see too much fuel pressure loss when the temperatures drops.

Well I live near Detroit where it's pretty cold and I don't have anything to monitor the car. They say it's a year around tune but figured it would be safer this year. For anyone who does switch what times of year do you switch back and forth?
I switched to my low octane tune in November. Shitty winter gas and I don't exactly need the extra power in the snow/ice.
Are people with 93 octane going to 91 or even lower to 89? I went from 93 down to 91 but still filling with 93 V Power
I monitor my car constantly and went to the 91 tune but still run BP 93 gas in it. The LOR has settled to -.79 even with the 91 tune, but honestly it's pretty much perfect for the winter since I'm not trying to beat every ounce of performance on it. This setup gets me almost no part throttle knock and WOT is fine (although as mentioned I don't do that much if its cold). Was -11 here this morning and everything is running great.
I have an 87 tune that I've been running in the winter.
All of my tuning started in late October after we had already switched over to winter blend fuels, and my latest 93 tune/log was done at less than 10*F, so I already have a pretty good margin of safety built into mine. :)

My fuel potency doesn't seem to change at all between the seasonal blends and I'm in one of the "boutique states" which is code for excessive EPA meddling.
OAR is still at -1.20
Still running my 93 e20 tune @14psi... it's a warm 8 degrees outside. Car loves this cold weather!!!(http://uploads.tapatalk-cdn.com/20170110/bee209028b97be6991e647763bb3f0e2.jpg)

I run my LME 93 Tune all year around with no special E-blend required just a bottle of heet at every fill up goes a long way.
It seems we have a heat wave today. Z

Isn't heet essentially just alcohol though? So sort of the same idea as doing an Eblend in the winter or running meth in the winter?

The MSDS lists the main ingredient as being Isopropanol which is just Isopropyl alcohol.
I wonder if they do anything special to distill it, or if it the same as the alcohol you can buy in the pharmacy.
Do not use iso HEET, just HEET, which is methanol. The difference being you are treating the gas in the fuel tank rather than supplementing the fuel source.

Gotcha, I was just trying to confirm that is an alcohol based additive, which it appears both are. So in essence, adding HEET would be similar to adding a small amount of ethanol or a little meth injection to keep things clean. That's mainly what I wanted to know. Thanks!

I would make certain its the yellow bottle which contains methanol. Z http://www.johnsens.com/uploads/files/2952.pdf (http://www.johnsens.com/uploads/files/2952.pdf)

Our most recent tune (V10) which it appears that you have, is a fantastic all weather, year round tune. We do see customers step down from the 93 to 91 octane tunes
as a precautionary measure, mostly for inclement weather instances. But otherwise you are perfectly fine running the v10 year round!

I don't understand why the need to "detune" for inclement weather. Just press less on the skinny pedal..

To each their own in this case. It is a preference case, and is purely based on driving habits.

My lead foot is impervious to inclement weather.
I only have enough leg strength to keep it off the pedal long enough to reach operating temps, at which point I'm forced to release the weight. Maybe I should start working out.
