There are testers for ethanol content, I believe, not very cheap, but affordable for occasional use.  No similar kits for octane evaluation though.  4DR I think offers the ethanol kits on his site?

IHG, any insight you provide is helpful.  We just need to figure out how to integrate it with our end-user experience and technical/research data available out there, public or not.  Tough job

Think those are the highest power #'s yet recorded on torque. Zero knock also!!!

That's on custom blend E16 right?  Great numbers and a nice gauge layout. I've now located my nearest E85 source. Gulf station about 2 miles from the house. I'll try adding 2 gal of E85 on my next fill up and see what happens to my KR, LTFTs, FRPs and gas mileage. It's either that or run a 91 octane, 3BAR version of 4+. I really like 4X and I hate to switch it out in the winter but I just can't close my eyes to seeing KR spikes between 4 and 5 even if it's not at WOT. Just feels like I'm running too close to the edge for comfort.

Thx Larry. 16-18% as I'm still in search for the supplier of the e/85. I guess now, have read differing opinions now, that some e/85 may take a "winter blend" mix hit also(regional mixes). 2 gallon per tank mix really makes it easy to figure out the required amount.

That high KR was what I could not deal with either. First thought my car was hurt before confirming the winter gas arrival. Whew!!!

Really hope the guys not monitoring knock out there see this info and adjust accordingly. 93 tune + winter blend + not fully warming up car = a considerable amount of knock I can assume pretty confidently.

Can you elaborate on your suspected connection/rationale to the not fully warmed up and the KR so I can check that on mine also?  Of course I never push my car till at full operating temps, but I have never been able to connect my winter gas spike readings to any driving style, temperature or situation. With the exception of my random tranny glitch causing a super spike readings of as high as 7.

Had to run one of the boys to school the other morning(bus showed up, well flew by 10 minutes early)and not fully warmed up the slight throttle that usually scores negative return was pulling timing. Pulled over and let car warm fully and it was gone. Albeit a short and only one time experience I have not tried to replicate. Combine that with previous winter blend issues and I can only assume it's not good.

Rich

Pretty anxious to see you guys that do monitor try this out. I had no baseline #'s to compare my now watched fuel related gauges to.

Rich

That's an easy situation for me to duplicate. Can't wait to try it. That could very well be where my high readings are coming from. I just have not caught it and made the connection. I'll let you know what I find. Thanks for the tip!

Eagerly waiting on the findings! As my lone experience is hardly "evidence".

I don't believe that is an issue of any kind. I think that is the ECU is protecting the engine until all is up to temp. Boost is always limited as well.

Thx for the reassuring comments.

Stated for extra warnings to all, for the incoming frigid temps.

Torque and the scantool proving to be one of my favorite mods so far.

Well here is something new. I actually caught the positive 4.5 right as it was happening. Not a mystery any more. It was lugging at moderate throttle. Not enough throttle for a down shift but enough to get low low vac or maybe a little boost and voila 4 positive KR. I nailed  it right after and at WOT no KR or even a little negative. So I think it's octane deprived winter gas at part throttle lugging.

I can jive with that.

So, even with running a higher E content, this issue is present?  wasinger?
