Any octane, any task, one tune…… That’s how this started, ‘there can be only one’. Having fun with names is just a start to what we believe will become our most popular tuning options. Welcome Highlander and MacGyver, Brew City Boost’s new Any Octane EcoBoost Calibrations.
To get started let’s talk about BCB’s calibrations types and how they fit and where each one excels. We identified some deficiencies in the current EcoBoost market and we’ve developed two new Calibrations to specifically address what we’ve seen. We now have developed two new tune calibrations which share the same roots, and in which we have implemented our newest shift strategies. We’ve built upon Ford factory style of calibration by expanding the capabilities of these new tunes to work across different octane fuels. This results in consistent and predictable results right out of the box that will not require any data-logging or revisions. These new calibrations will adjust boost pressure and spark according to whatever octane fuel you have filled up with, from 85 to 93 octane. There is no longer a need to be tied to running a specific octane because your tune requires it.
Highlander – Adaptive Calibration
We started with Highlander, this tune is now our most flexible and highest performing Adaptive Calibration. This tune will allow the highest boost pressure and most optimized spark advance for the given platform per octane. This tune is a serious all arounder, it’s hot enough to have fun and also hurt some feeling regardless of what octane fuel you have in it. As we were developing the Highlander calibration we did however realize one potential drawback of that tune and it’s related to those who tow regularly and heavy loads. Highlander may be just a little too hot for the sustained loads a heavy trailer could present.
MacGyver – Adaptive Calibration
With the potential shortcoming of Highlander identified we decided to branch that tune into one that is focused on heavy hauling. MacGyver will be provide great pickup in horsepower and torque from stock, but register in a little lower in output power than Highlander. We created the MacGyver calibration to be more modest in terms of gains in order for it to be the most efficient in all aspects of what trucks do. It really is a workhorse. Throw your big loads at it and put it in Tow mode and MacGyver won’t skip a beat.
How do Brew City Boost’s Adaptive Calibrations work?
Our Adaptive Calibration leverages Fords factory calibration and expands upon it to support higher outputs. The nuts and bolts of how it works boils down to OAR, an inferred value that is indicative of fuel quality. The EcoBoost ECM can infer fuel quality by octane and spits out a value called ‘Octane Adjust Ratio’ or ‘OAR’. This value is an indicator to fuel quality, and has a range of -1 to +1. Higher quality/octane fuels will yield a number closer to -1 and lower quality/octane fuel will yield a number closer to +1. Our calibration then utilizes this value to determine what load, boost pressure, and spark advance to apply to that OAR value. OAR is a constantly updated value that you can monitor on your tuning device. In general the ECM will make updates to OAR when under specific conditions; Engine speed is between 1200 and 4000rpm and Load between 0.5 and 1.5 for at least 6 seconds in duration. This OAR adaption can be forced by monitoring these parameters and keeping within those windows specified. After you’ve filled up with a different octane fuel, you should always give it a few miles for that fuel to make it form the tank to the engine and also allow OAR to adapt. Usually around 10-20 miles is sufficient if you are not forcing the adaption of OAR.
We’ve spent many hours recently reworking our current shift strategies. These have been adjusted to work optimally with our new Highland and MacGyver Adaptive Calibrations. We have adjusted 3 modes, normal, sport, and tow. Each one is specifically tailored for that desired mode for the best in drivability, performance, and economy.
In Normal mode and the stock tune the transmission does a good job of keeping you in the right gear for mpgs, however once tuned that shift schedule needs to re-calibrated for best results. Some of the best feedback we’ve got regarding shifting on these trucks is that will go into 5th and 6th far too early, and also hunt in the 4, 5, and 6 range frequently as if it were confused where it should be. We’ve added more separation between these up and downshifts and run out the gears a little longer before the shift to avoid any unnecessary ‘lugging’ of the motor. We’ve also kept in mind this shift schedule should maintain some aspect of economy.
In Sport mode is where we let these transmissions have some fun. Our sport mode is very aggressive and keeps you in the right gear for immediate power on demand. We implement extremely sporty and fun downshifts under braking and lightning fast up-shifts with optimized wot shift points.
We have spent most of our time refining tow mode as it’s really at the core of what makes a truck. We want you to feel as if there’s no load back there, your engine and transmission are in complete sync with each other the whole time. You won’t hunt for gears, it won’t shift when it shouldn’t, and it will downshift when it should, always allowing the best transfer of torque under any given condition.
Custom Logged Calibrations
So we made some cool new tunes and they seem to tick all the boxes, how does Brew City Boost Custom Logged Calibrations fit now?
Our custom logged calibrations are still our powerhouse. They are the task specific tunes, to really get the most out of your truck for whatever your goals may be. Some want to race, some want to tow, others want economy, and most want an optimized tune specific for them and their truck. If you don’t need flexibility of fuel type and want to be involved in the process of tuning, understanding how your truck is performing, and have your input directly implemented into a calibration, than custom is for you. Our custom tuning isn’t a finished product out of the box, it takes a few revisions to get the tune completely optimized to your truck. Typically this is 3-5 revisions, could be more depending on what we dive into. What you get out of the box is generally 80-90% complete and through data-logs the customer records we are able to optimize the tune specifically for your goals to get to a final product.
