Another concern is that in some cases, the AFR is not within 1% of my Command AFR in some areas of acceleration with the exception of when I am shifting gears which is normal. Can someone take a look at my DataZip and let me know what they think? Things I have yet to do, scale my MAF while on Petrol and adjust any timing (even though it has been recommended to do since the OFT e85 Stage 2 is only recommended to be used with e60-90). Thanks in advance.

If you are running the e85 map you will be 8-17% negative in lftf always unless you go and physically change the tunes fueling/timing. The longer the computer learns the tune the more negative you will see. The reason being is our e85 is no longer that. Its about 51%-61%. the system sees you running richer now duel to the petrol mixture being higher. You can get a flexfuel kit or change the tune or leave the tune alone and run with it if you arent getting knock. I have been working on my own tune for the new "flex fuel" we have here and its pretty good so far still needs a bit of tweaking here and there as its getting much warmer out. Iam still at 1 and WOT pulls are there till redline.
If you just flashed you need to drive more and data log more time. There is only 1 possible knock that i saw on that log. At work so its hard to see on my phone, lol. I usally log after flash only to see if its bad knock or knock and if its bad or alot i change if none or hardly any i let the computer learn and log. I then take the logs after 100 miles or so and then look at flkc and knock correction if knock adjust accordingly. The computer makes quite a bit of adjustments on its own as it learns, why you can run the new flexfuel on the e85 map as its learning the. Ew fuel curve its taking out the unnesscary fuel thats being added.
