I ran a separate power wire from a new mega fuse I put on the car. It's hooked up to a relay that gets energized from a trigger wire in the fuse box up front. It's all in the thread I linked, but the electrical stuff was all done according to suggestions and planning from @SSgtjrobertson . If I want to disable the whole system all I have to do is pull one small fuse.
Ya i saw that, was reading the post. i have a week of research to do before the wife takes the baby out town for 4 days for her sisters baby shower. A weekend just me the dog and a meth injection system to install. life is good.
There is a fuse box in the rear on the left side behind a removable panel. Do you know if a fuse tap can be utilized there?
What do you mean by this?
Our Performance tuning on the ecoboost platform will adjust automatically based on what octane fuel you are running. The tune will read 87-95 octane fuels and adjust timing and boost. Keeps from having to change tunes depending on the fuel you put in the vehicle.
oooh this is good news I like hearing this, looks like you guys are the 2nd tuner I've hard of who are doing this. Good to see more people leveraging this functionality. Do you have a method that allows this to work on big turbo? or just the stock turbo?
the car in this thread is auto octane.
That's awesome.
This is really cool, octane learning on big turbo tunes is unheard of currently.
I have only run 93 since tuning it. We stay extremely busy so finding time to work on personal vehicles is hard. We dont really have a Focus market since there are so many good tuners already out there on this platform. Also seams like everyone wants the Cobb AP and we are primarily on SCT. I had to wait quite a long time to get mine on the dyno for the big turbo tuning since its hard to find time.
To my knowledge the ecoboost platforms use an auto octane stock calibration style. The owners here have figured out how to enhance the stock tuning for performance while leaving full diagnostics on for safety.
Yeah they do from the factory, and the implementation of that can still be used on stock turbo (hence monster doing the adapt-x tune) but i just didnt think the ECM had a capability to manage proper octane learning with a big turbo. I'd imagine the car would still be reduced to 240hp or something on 87 if this works the way it's designed to on the stock turbo. I'm really interested in if this works if you guys ever get time to try it out. I would never ever run anything but 93 or e30 if i had the choice, but what it would show me is the ability to adapt to fuel quality changes even at the 400hp level.
If you add octane learning to a commercially available tune you’ll have a feature that currently only one other tuner is using right now. It’s a very rare thing in the focus market.
my stock turbo tune was auto octane as well. i just dont know when i can get back on the dyno if we decided to see what numbers were on 87.
we have support for auto octane on stock turbo, we just dont push it because there are so many other tuning companies that have the market cornered. especially with the Cobb AP, which we are on SCT. not alot of folks want to use it or switch.
Fair enough, just always like to see new methods and ideas applied to the platform
what year is your focus? i could probably talk a tuner into throwing a tune out for grins if you have an SCT deviceFair enough, just always like to see new methods and ideas applied to the platform

its an '18, but I have a Cobb AP, and I'm working with another tuner right now to go big turbo, so I can't assist sadly
