Pulls hard and no issues!

Can you elaborate a bit on your experience!

I got a 16 ZCP that is soon getting HEX, I'd like to hear some details!

My username probably didn't give it away! I have 6mt

With every car I've had the car ALWAYS feels "torquier" right off the bat because the adaptation data gets reset and the gas pedal becomes extremely sensitive

I could BARELY put my foot on the gas and the car would try to shoot forward and then i'd let go of the clutch and it would buck like crazy. It was more funny than anything but awkward driving through malls or shopping plazas

Previous cars only took 10 miles or so to get all adjusted but this one took a good 800 miles to where the car fully adjusted .

Interesting. If it took 800 miles, just wondering if it could be that your body adjusted to the throttle sensitivity rather than the car actually adapting?

Or was there a dramatic, noticeable difference after adaptation?

I read your description that says 6MT as well, I just never heard of such a long adaptation period on a manual.

That sucks though, because if you flash back to stock to get it serviced then you have to adapt again?


What stage do you have?

I have the same issues. The car is very jerky at light throttle application and driving away in 1st and 2nd gear.It bucks like crazy.
Just like in this video from VF:

YouTube

I have reset the adaption per Technical department of VF but after more then 300miles it still the same.

Anyone else with this issue?

6-Speed Manual.

[VF-Engineering]

That's definitely an abnormal length of time for adaptation, but
interesting to note nonetheless.

We have been extremely adamant that this is a factory symptom
that becomes exaggerated with the increase in torque; and that
adaption will help to smooth things out, along with retraining
your muscle memory as you get used to applying less pedal
input to achieve the same rate of acceleration.


Manual transmission cars do take longer than DCT as the clutch
engagement and shift points are not nearly as consistent when
controlled by the driver vs. the TCU.

It may also be interesting to note that manual owners tend to
favor driving in Sport+. This doesn't help the cause as it's also
the most sensitive of the 3 driving modes; but as they say...
"patience is a virtue" as it will inevitably smooth out and
ultimately be even better than OEM.

I can totally tell it's adjusted and the sensitivity has gone down because before the car was almost undriveable and it was really getting under my skin. My wife drives it here and there and she also said that the car is finally back to normal. Just a very abnormal time period.

That's correct! I went to the dealer for service and thought just that so I left it. My warranty expires in September anyways (15 model)

I have stage 1 and drive in Sport with suspension and steering in comfort

Efficient is much less sensitive but during the adaptation period it was also hilariously touchy

Yes! That video shows it perfectly, I remember seeing that too.

This was across all three drive modes, but now it's normal. Muscle memory has something to do with it as well as how the manual works in this car

I feel like the clutch grabs very very high and as you're letting off it applies throttle as I can hear the engine rev up but that's also the gear engaging but most of the times it's all clutch play in parking lots as I don't even need to touch the gas

With previous cars I couldn't just let off the clutch slowly without throttle or I would stall!

This tune is dangerous though, I find myself at 100+mph so quickly (in Mexico of course) so I set a speed warning so I don't end up in jail

I wish my stage 1 would hurry up and adapt, it has been 1500 klm's, why is this ? very challenging to drive in Sport + (DCT). On the positive side it is day and night difference compared a piggy back tune I was running. Just waiting for my downpipes to arrive and then heading in for the stage 2 injection.

I experienced the same thing.... I drove from Melbourne to Brisbane and it was still shit. What I ended up doing is resetting adaptations myself and that fixed it for the most part and slowly got better. I still think the low speed small throttle inputs with this tune needs work overall.

I agree with this, second and third gear need to be checked out.

Agree, low speed small throttle inputs are crap in every mode except efficient.
Its bull shit that you had to reset adaptions yourself after paying for someone to tune your car. How did you reset adaptions.

Downloaded the software off the VF website and followed my nose reading the guide prior. Was easy as and took 5 min's.

In the hills and driving aggressive it's great, but daily fine throttle inputs it needs to be improved.

Thanks for that info, I think I will just go back and have the Hex dealer sort it out. Agree with you on driving hard, it is a beast. Not that I really worry, but fuel economy has only increase by .2 litres per 100 klm's.

Thanks to all the guys at Hex tuning( especially Abraham , Great customer service and a awesome tune for stage 1 ....Just installed the stage 1 tune and the results are amazing....had a piggyback set-up that quoted a horsepower gain from 431 flywheel to 510 flywheel...but the hex tune feels much stronger!!!!! thank you, thank you, thank you...this includes exhaust popping and topspeed raised to 192mph...plus new dyno display showing 640hp

Question: How does your 30-day return policy work? Just flash back to stock and ship the cable back?

[VF-Engineering]

Yes, it's just that simple ...
...the only thing to note is that one of our techs will actually
log in remotely to oversee the "flash to stock" process, and
once complete, will "lock" the HEX Flash Cable.

Once the cable is shipped back to us, our accounting dept.
will immediately issue the refund.

Ha, okay, that was going to be my next question on how you would confirm it. Not that I would try to cheat you out of the tune or something.

Yeah, it's not about anyone trying to "cheat" the system,
but rather being confident that the vehicle was properly
flashed back to stock so that the customer can pursue
other options in the future with no issues.


Some might be surprised to know that of the large number
of vehicles we flash each month, we still have less than a
half dozen customers in total (between ALL F-series models)
who have opted for their money back!

Of that 1/2 dozen, one has actually returned to HEX Tuning
after trying another brand, while another customer actually
took advantage of the return policy TWICE.

We purposely made it a very liberal policy to instill confidence
by standing behind our product, well before there was any real
competition in the market place!

This guy knows what's up! Just get it every boost season!

Hey vf, what sup with torque limit map?

We pulled the plug on that project quite some time ago, around
early summer last year. We tested it with a few local customers
and the reviews were a mixed bag.

The general consensus was that vehicle setup and surface
conditions made a far greater difference than what was
beneficial through the software.



Everyone was excited about it at first, but then they realize all
you are doing is limiting the power, and once they find the point
where you're not inducing wheel spin, psychologically the car
feels much slower and you want that extra power back.



I think what they learned is that their right foot has more
control over power delivery than they gave themselves credit
for.

The initial increase of power (with torque being increased by
more than 100+ ft. lbs.) is initially a lot to handle on less than
ideal surfaces, but after a decent amount of seat time you will
get used to the power delivery and learn the modulate the pedal
with more precision.

It's very similar to the first time you drive a car with racing
brake pads. By the 2nd or 3rd lap, you're fully dialed in and
much more confident.
