Another update, I decided to move down to the 2 bar tune. And no difference, I then swapped out the 3 bar sensor for my newer one (from the 3 bar tune) reset the adaptations and it appeared to be gone. I picked up another 3 bar sensor and loaded the 3 bar tune again last night. Unfortunately it's been raining for the last 2 days so I haven't been able to really test it out. Although, I did notice that Torque was reporting 16lbs of max boost before the swap. I don't recall ever reaching that much boost in the past. Once the roads clear up (hopefully tomorrow) I will know better.   

The KR has not been effected at all by anything I have done.

Misfire is gone! However KR still remains unaffected. 0 RK at WOT though.

That seems to be a common experience, KR when part throttle or lugging the engine only.  Seems a little more oxygen in the fuel may do the trick, as the issue is not really controllable (thus far, to my knowledge) via a tune.  Can you correlate the KR events to trans shift points?  That's where it's pointing to on my Edge, and surprisingly, only once the trans temps rise above 100F.  Of course, could just be a worn transmission, but doesn't feel like it at all.

This may be related to this issue?  http://en.wikipedia.org/wiki/Low-speed_pre-ignition

Interesting read, I guess it is quite common. I wonder how the engine oil fits into the equation.

So I decided to try a different station for my fill up. Big mistake. LOR went to 83% on Forscan and KR was really bad. Started getting 3 at wot and 5 on mid throttle. 91 tune was only slightly better. So back in goes the stock tune for now. After doing some looking around the net. It looks to be common with 10% blends. Shelf life is max 90 days. And much less in winter months with condensation issues with water contamination. Looks like I will be going to 91 Shell that has no Ethanol.

But doesn't the ethanol help raise effective octane?..so u want E0 when most pumps are E10-E15....I thought that's what's so good about E85 is the ocean rating...so with e10 he octane rating will be slightly higher than pure gas at e0

If it's not fresh than no, the issue that I have read is that once the Ethanol absorbs any water it falls to the bottom of the tank at the station. Dropping the rating of the fuel up to 6 points. So basically I paid extra for 88 octane fuel. I am guessing that the last station does not sell a lot of 94. Hence the "bad" gas I got. 94 is a 10% blend up here. There is no where to get anything above 91 that contains 0 Ethanol around here. With the exception of "race gas". Shell 91 here has 0 Ethanol, which supposedly holds its Octane rating longer than an Ethanol blend. So back to the only conclusion that I can draw is that the pumps around here have some old 94 in them. The last in particular was really bad.

Torrie cured my lugging high kr issue with a tune adjustment.  I will post the data log from torque later.

So you have HEET type products available, ShoBoat?  Methanol + water dispersant.  I am testing it now based on Z's reco,  Add a bottle and see what happens.

I have tossed in a bottle of Heet. I will report back.

No dice, still the same. I'm going to run this tank down and try another station.
