    The handheld allows us to flash the car remotely. It can hold the stock (factory) tune on it, plus up to 10 additional tunes.

    Our tune includes the following features:
    Increase 30hp/20tq safely on 91 octane
    Increase throttle response
    Remove cold start
    Remove speed limiter
    Raise rev limiter
    Exhaust flap control
    Add burbles
    $3500 which includes the handheld

    Interesting. Does this thing allow you to see the data live remotely during dyno or street tuning? How much are subsequent tunes once the customer owns the handheld? Can the customer easily switch between various tunes? Also are the tunes custom for multiple Manettino positions? Ie one ECU program contains multiple custom maps for each manettino setting?
    Are you making changes to the transaxle programming also or just fuel maps?

    Thanks!

    Hi Mikey!

    Unfortunately, this tools purpose is to flash only, we are lucky we have the ability to store multiple tunes, and this tool flashes a plethora of models so the additional logging capability would greatly increase the cost of the flash tool. We have recommendations for tools to use to log, and if you want to send us logs we can of course customize maps for you.
    However, it's important to note that all we are doing is removing artificial limits in the ecu so the car can hit its natural potential, on pump gas especially custom tuning will see very little gains (unless there are heavy mods) because it's already closed loop fuel, meaning it's target based. We set a target and even if you slap turbos on there it will hit the same target. No additional safety or power from customizing the fuel and then we just have timing and cam timing to focus on. Cam timing shows very little gains on this motor as it's incredibly aggressive from the factory. You can see low end torque is almost nothing then this car makes all its power high end. We clean up the timing maps as they are pretty lazy, but we don't force timing in the car. If you make a single hp at the expense of reliability, you're not tuning properly. The car will make the most power in its safest configuration, it's not like the old days where you lean out a car to make more power and cross your fingers that it doesn't send you back to 1888 with doc brown.
    The manettino positions work as factory, but the characteristcs are more pronounced as we are removing the shackles from the calibration.

    This is a throttle response map in the med9.6 ECU. The difference between our tuning and the copy/paste tunes circulating the internet is noticing anomaly's in factory mapping that adversely effect the smoothness of a car is an art more than science. You will notice that the 458 throttle is extremely touchy and with poor tuning this becomes MUCH worse. The initial tip in goes from a value of 0 to a value 100% higher at the first cell on this map. Add burbles or remove torque limits and you have a very very jerky car. Looks like a teenager learning to drive stick for prom. The short comings in the factory car are fixed by us. I know everyone puts Ferrari on a pedestal, but let me tell you something. Engineers are lazy. Italian engineers???? They do as much as they have to unless it's time to show off. The car makes enough power, the car drives well enough, it's totally fine. It could be better. That's why we have a job.

    This is a timing map with the full load section highlighted in the foreground. The jaggedness of this map shows how lazy the engineers are, a smooth timing map is always preferred for consistent power.

    This is a smooth timing map for comparison—this is the optimum timing map.

    Giving this information out publicly is against our interest as a company. Showing the competition things they should be paying attention to does not increase our profit, but it does help the industry as a whole. Our competitive advantage is our continuous development, not that we bought a golden calibration from some mysterious recluse in a basement somewhere and copy paste it blindly without knowing what each change is there for. That's how most of this tuning industry works and it goes against the very definition of tuning. It's the difference between a fitted suit and off the rack. Rolex and Seiko both tell time, but we are Ferrari guys for a reason, we have discernment. We feel these things in the wheel and in our bones and when the car is missing the mark by a bit we obsess over the minutia. We spend thousands of hours unpaid to refine our calibrations so giving away some secret sauce will just help the competition give the industry what it deserves. A tune with some knowledge and thought behind it, not just a blanket guess adding 5-10% to the timing maps, leaning it out, setting some values to FF and hope for the best.

    Thank you for your detailed response. Great stuff! I’ll reach out directly sometime soon.

    Cheers,
