Yeah it just takes a bit longer if you have the original rom type on your car. But if you've already got CustomROM on there, then it's as fast as ever

Just did it for a friends m3 today. Flashed with iPhone. Bend Calibration’s ultimate flex fuel kit installed.
Did 3 runs on our local heartbreak Mustang dyno, ARM resonated downpipes SSR intake MPE exhaust OEM flex fuel plugs gapped 0.024” We flashed the stage 2 multimap Run 1: pump gas (93 equivalent) 386whp/ 587tq Run 2: E27 403whp/ 606tq Run 3: E53 420whp/ 631tq I suggest not looking at the absolute figures as they won’t compare to your local dynojet, but rather take away the delta in between different E% Boost stays the same all 3 runs at 22-23psi, regardless of E%. Ignition advance becomes more aggressive with more E. Dyno graph showing pump gas vs E53 Logs: Run 1 https://www.bootmod3.net/log?id=607e...0b431316c7dc79 Run 2 https://www.bootmod3.net/log?id=607e...729b77cf8e38a4 Run 3 https://www.bootmod3.net/log?id=607e...729b77cf8e38c1 Last edited by E92inSG; 04-21-2021 at 02:03 AM.. |

So I completely forgot about virtual dyno, and entered my Stage 2 ACN91 log into the program to come out with an estimated 485whp/567tq. I'm not concerned with the number but I do want something to compare an E30 or even full E85 tune down the line. I also attached the log for the pull.
Pull was done in third gear. https://www.bootmod3.net/log?id=607f...729b2fee19b41a |

Edit*** Interesting I just looked over your logs vs my straight 93 log. I am seeing 14.5° timing vs 10° on your e53 log. Your 93 logs seem to be pretty low as well. But your boost pressure is 4# higher on all logs. Just an observation but seems strange. https://www.bootmod3.net/log?id=608d...90c6744776b511

in your logs it's looking like boost is being pulled at higher rpms and then timing advanced even further to make the power. Strange that both these OTS maps have differing strategies

Valet mode can be had with custom tuning. Currently running a multimap setup with:
Slot 1 - full E85 Slot 2 - 93oct Slot 3 - E85 valet Slot 4 - 93 valet Other option is using bm3 settings to cut boost in all gears. But, that would require flashing the car back and forth, rather than being able to switch on the fly.

Not really sure how to answer that since it was a custom tune I purchased and the details are locked from being accessed.
But here are a couple of logs to compare how significantly the performance is cut back compared to the last pull I logged with the regular 93 map. (One caveat - the non-valet 93 log is from over a year ago since I have pretty much been running constant E85 now that a station was put up right down from the house. There were a few revisions made to the updated map that got included in my multi-map customROM, I just haven't taken time to log pulls with it.) 93 valet log: https://www.bootmod3.net/log?id=6061...0b4308c75b5f7a 93 non-valet log: https://www.bootmod3.net/log?id=5e17...90c660d027d5cb

I refer to it as “Wife Mode” around the house. Doesn’t get as excited of a response. |
