HEX Tuning by VF Engineering - available NOW for all Carrera models
We've been teasing the release of our 991.2 ECU Software for about a
month now via Social Media while we collected more real world feedback
from various customers, and now it's time to make it official along with our
return to the Rennlist forums!

For those who are not aware, HEX Tuning is the in-house software division
of VF Engineering. VF Engineering is the engineering and manufacturing
side of the company, responsible for any physical products you can "touch
and feel" while HEX Tuning is our software development / testing division
for anything ECU/TCU controlled.
At our Anaheim, CA facility we have a full engineering staff & two in-ground
dynamometers.
- Mustang AWD-500-SE
- DynoJet 224xLC
Every vehicle begins development on the dyno for baseline testing with data
logging in full stock condition before any calibration changes are applied.
From there each application is dyno tested, street tested, and track tested
(when possible) in order to properly compare the results under real world
conditions to our controlled testing.
All results are validated across multiple vehicles to ensure consistent results.
Advertised gains are based on averaged stock runs -vs- averaged tuned
runs in order to provide gains that are easily realized by independent 3rd
party testing.
Under promise and Over deliver!
And now for the good stuff ...

CUSTOMER REVIEWS
My thoughts stock vs Hex GTS Tune:
"The increase in boost from the tune creates a better pedal feel. The stock car felt
like it had “accelerator lag” and the pedal was mushy. It required about a 50%
depression to really activate the turbo spooling to what I like to call “movement
on the road”. The added immediate boost and torque are clearly indicative here
as the car just thrusts upon the slightest depression. But the response is not
overly sensitive either, it’s proper in feel and depression based on my needs.
From a roll, because of the improved hp/tq curves thru the regular usage rpm
ranges, this creates more rapid and overall top end acceleration. Speeds of
140+ have never occurred this fast via the OEM tune. The car feels like a baby
Turbo 991.2 but with the 300 lb weight loss.
From a dig- the car launches violently but in a way that any aggressive driver
will smile at. If magazine tests have the GTS RWD hitting zero to 60 in 3.1
seconds then this car is going to be right under 3 seconds in perfect conditions.
The most important gain or benefit for me with the tune is true driveability gains
thru rpm ranges of 2k to 6k where the tune curves bloat clearly over the factory
drawn lines. And you can feel it from immediate tip in to WOT throttle. It’s a
well balanced tune where when torque drops off; the car is well past 6k rpms
and the hp curve keeps climbing. For daily street driving the added torque
limits really assist in quick lane passes.
There are many options out there and some sell based on paper dynos but
this tune will sell on its driving merits." - Vik55

Good question!
YES, the protocol for this ECU still requires being unlocked
on the bench. We turn ECU's around the SAME-DAY as we
receive them, as long as they are received by 10:30am.
The price of our software will include FREE return shipping
by UPS Overnight to ensure the minimal amount of down
time. If you remove your ECU today, ship it via next-day
transit, we will have the ECU back in your hands by the
next morning. (total downtime is less than 48 hours)

Any straight e85 options?

No sir.
Despite the benefits of the higher "effective octane" rating and
cooling properties, we're just not fans of using E85 on vehicles
without proper alcohol monitoring.
That being said, I think most people will be very pleased with
the power gains as advertised on 91 Octane,... and they can
still take advantage of the ECU's adaptability when running
higher octane unleaded fuels to make slightly more power,
even more consistently.
Our tuning philosophy is based around everyday usable power.
We've found that while peak power gains inspire interesting
conversation and can help spike early sales for those who make
their purchase decisions based primarily on dyno plots, we do very
well playing the long game by focusing on drivability, reliability, and
usability.
As a side note: Stage TWO power levels will likely have a strong
recommendation for upgraded inter-coolers as that's what we've
determined to be the first weak link for customers in relatively
warm to hot climates, or those who will regularly track their cars.

Your horsepower curve on the standard Carrera engine is dropping off pretty significantly on the top end. the Carrera S doesn’t seem to be as bad but the scale on the graph only goes to 6500. Does it drop off as badly or so the larger turbos make up for it?

Who do you recommend for Intercoolers?
Do you also recommend Plenum change for better airflow?

That's likely due to conditional factors for those particular runs,
coupled with the fact that that factory turbos are indeed running
closer to their optimal rotational efficiency north of 6,000 rpm.
We always post average runs, and never the "worst" stock run
compared against the "best" tuned run to artificially inflate the
results. A cold run which would be an example of the power
gains under the best conditions for that particular dyno session,
but may not be as repeatable and therefore not what we would
advertise with.
Despite the visible taper, the gains are net positive throughout
the entire rev range which is what we are always looking for.
Inter-cooling and/or higher fuel quality (better than 91 Octane)
would also likely improve peak and max gains, and is the exact
reason why we feel that intercoolers should be a recomendation
for anything beyond Stage ONE power levels.
we get a chance to test more cars with the various options we'll
have supporting data to make recommendations, but for now I'd
look to first hand real world reviews from actual owners.
For the plenum, we did actually assist in early testing with IPD
and can say that there were definite gains, primarily through
the mid-range from 3,750 to 5,750.
While this was on an otherwise completely stock motor, it's
safe to infer that the gains would likely be similar with higher
boost levels. For those looking to maximize gains with stock
turbos we don't see any reason not to consider it. Just keep
in mind that it's not a simple DIY install anymore.

Thank you for your response and I agree with you that doing this includes more components and not a simple DIY. My plan with tuning is also to upgrade the following;
* IPD plenum
* Alpha Performance intercooler
* High Flow air filter
* add front center radiator

That looks to me like a solid list of mods, all of which will
be complimentary to the software.

I used this company's tune on my M2 and was very pleased with the results. The dyno chart shown above, was that on the mustang dyno or the dynojet?

All "before and after" plots posted for advertising purposes are
going to be from the same session, on the same day, with the
same fuel, in order to produce the most accurate results.
For those who may not be as familiar with how to read these
sorts of dyno plots, the emphasis should be on the "delta", or
degree of change (improvement) between the runs.
"PEAK Gains" will be the difference between stock and tuned
runs at their respective high points.
"MAX Gains" will be the difference between stock and tuned
runs at the same RPM, representing the greatest improvement.
"Area Under The Curve" represents the total percentage of
increase across the entire rev range, and is typically used to
visually identify where the gains are most prominent across
the entire run.
The dyno plot below shows:
Peak Gains of 97 TQ and 50 HP at the wheels.
MAX Gains of 101 TQ @ 3,700 rpmand 73 HP @ 4,300 rpm
and the AUC demonstrates net positive gains throughout!
