Capturing any fuel trim data yet?  Though Torque's 1/10 of a second resolution may not be sufficient to capture the cause of the spike, hoping :)

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!

Bank 1 is definitely running leaner, much more so at idle.  Is that normal?  Also the numbers are much higher than on my naturally aspirated Edge, which tends to run maximum 2-4% LTFT.  Interested in seeing your numbers next time it is just pump gas (no blend).

My bank one also runs similarly leaner stock, stock+e, and tuned so I don't think there's an issue

Without knowing baseline straight gas numbers its really hard to tell how much extra enrichment is happening. What are your short terms doing? Are they close to zero?

No worries of a cel as that is allegedly tripped at +- 25%

Mine was well into the 30's at e55, no CEL or dtc's set.

My fuel tables seem to be completely different so the only thing I really have to compare is stock behavior.

Thanks for recording this Rich. Considering your custom blend fuel, I expected your LTFT to be higher than mine. Glad to see your left and right banks differing by a similar amount to mine also. I'm going to document my readings at the same speed points you chose so we can compare more accurately. Thanks again for checking this!

Thx guys...maybe some non mixed results from Larry can help us here. I would try a tank of winter blend to see the difference if the knock return wasn't so bad.

Found out the distributors name, Coorigan, of the e/85 at BP here.  Guy said he would know the brand next time for me.

Some observations from last night

LTFT1-------LTFT2-------Conditions

3.9-----------2.7----------idle

8.9-----------6.5----------50mph

8.9-----------6.5----------70mph

0----------     -3.5---------high vac/throttle lift off

No WOT test

Readings decrease under moderate acceleration

My gut is telling me to look for a small vacuum leak. I'm almost positive these LTFT readings are creeping up because my recollection is that when I started with Torque a long time ago, that they were up and down both sides of zero by 1 or 2 points. Not sure though....my memory could be playing tricks on me!
On the winter fuel issue next tank I'll try Mobil 93 and see what my KR looks like with that brand.

Larry my trims are similar to yours. I do not believe you have a vacuum leak. The only time I've been around zero for my trims is stock. I believe The car is compensating for the higher fuel requirement of being tuned...

That's some good news!  A much more pleasant theory than mine. Thank you for that info.

So fuel trims are still being calculated off the stock baseline?  That would indeed make sense :thumb:
