What app are you using and how does it integrate with the car? Sorry if this has already been answered.

A typical summer-grade gasoline is composed of fluid catalytic cracker gasoline, 40%; straight-run gasoline (directly from crude oil distillation), 25%; alkylate, 15%; reformate, 18%; and butane, 2%. Winter-grade gasoline usually contains more butane, which has an octane rating slightly below premium gasoline (91-93 octane). While butane is an economic component of gasoline, the high volatility of butane limits the amount of butane that can be used in summer-grade gasoline.

Just a FYI for those of you with issues like mine and higher KR than normal in winter.

So now that I have a few days on the 91 no Ethanol with the 91 Tune V8. I can say that the car runs a lot better. It even idles smoother, the only real issue that it is pulling more timing than I would have expected. With the above statement I guess it also applies to non ethanol blends. Today it's only 4C (39F) so it's chilly. Running the 91 V8 Tune on 94 Petro (with 10% E) the car ran like a bag of crap once the temp dropped below 10C (50F). Still winter blends I guess, I have gone over the logs from last year. Track runs in May of last year Temp at the time was only 8C and the car ran really strong. I got one of my best runs at 12.737. FRP was a solid 2200 psi the whole run (this was on 10% E). I wonder how different must the winter gas it to cause this difference in the car and tune. LMS has sent me a V7 with the cold weather tweak. I will be trying this over the weekend with some 10% Ethanol 94. More to come.

Maybe it will do better once the temps get above 10C.  Can't store the tunes locally any more?

Winter blend is horrible for KR...have you looked into what time of year you get summer fuel back. May 1st is the deadline in the States for stations to have it in their pumps.

Yes the tunes are stored locally.
I believe that May 1st is also the deadline for Canada.

Loaded up V7 CW 91 Tune. It was time for a fill up so I went with 94 with 10% Corn. Initial results are interesting. I was actually surprised, KR is reasonable (we still have winter gas up here) And its cold, only 4C tonight. I couldn't feel any hesitation or misfires at all. I will do some data logging and confirm. The car pulled really strong. So strong that it roasted the tires right through first gear and part way through second. (the cold and summer tires are partly to blame for that) but it still felt really cool.

The corn is not hurting your KR.

On a DI car, I'd choose s*** gas with corn over straight s*** gas.

^^ I agree unless it's old mouldy corn

s*** gas with corn?....I had qdoba tonight.....it will be moldy corn tomorrow

You might want to see a doctor then, lol....

Ok so a bit more driving and testing. I was sure it was gone at first. Not so...... So from a standstill the car pulls great all the way through to the end of 4th. From a roll at 30 mph to WOT down to 2nd gear no problem pulls great again well into 4th gear. Now here is the kicker, at 55 mph and WOT same issue as before. Hesitation and misfires. WFT?? FRP drops to below 800PSI. On the other runs it holds well above 1500. If was a mechanical issue for example pump you would think it would do it all the time, not just from a 55 mph roll. I have sent the latest logs to LMS for their thoughts.   

See below for the charts, first is 30 mph 2nd is 55 mph.
