That is absolutely correct!

Not sure if you've seen it yet, but we posted a thread explaining a bit more
about dyno tuning in general and our philosophy on making usable power.

You can see it "HERE". (click link to jump)

Yes thats where I saw it, could you explain a bit more on what happens on the Mustang Dyno and why is the same tuning can't or not done on Dynojet?

It's partly based on how our workshop is laid out, and partially based on the workflow
we've devised for development projects.

The Mustang Dyno is really just the work horse of our facility (no pun intended),
while the DynoJet is primarily used for short term projects and performance measuring.

It's not uncommon for new projects to spend weeks at a time on the Mustang Dyno for
calibration testing and data-logging. If we want to install EGT probes into the exhaust
manifold, monitor temperatures on various engine components, or test multiple software
versions and/or hardware combinations on the same vehicle, it's more efficient to use
the same dyno without having to take the car on and off multiple times.

We can accomplish similar feats with the DynoJet as well, but it was strategically placed
in the workshop in a manner that allows for more convenient access and quicker vehicle
changes for comparison purposes. We do perform light duty calibration work on the
DynoJet but it's primary purpose is measurement testing since it has sort of become the
unofficial "industry standard" when it comes to marketable numbers.

While most performance enthusiasts are starting to understand that peak numbers mean
very little without proper context, the allure of 375 HP versus 350 HP is still more
compelling, even if the delta or area under the curve is greater on the 350 HP car.

It's necessary to remove and unlock the ECU MEVD17.2Y ?

Yes, it is necessary to remove and unlock the ECU in order for us to enable
port flashing. The good news is that once unlocked, all flashing processes
will take place through the OBDII port, which is (literally) less than a two
minute process.

This includes switching between Stock and Tuned MAPS, upgrading to the
next Stage Level, and any significant updates that we may release as we
go along.

Wow bm3 says its takes 30 mins to switch maps with their software.

[wakeofdeath]

Do you have a Mustang Graph of the Stage2 as well?

[lokito]

Please PM me prices for both Stage 1 & 2. Thanks!

30 minutes where did they write that? Completely false. A regular map flash switch takes 1:45 seconds. Full flash restore takes 4:00 minutes.

What you do with that remaining 28 is up to you .

The 30 min could be the time it takes to get the ots map to the laptop when having a very poor download speed.. as in miserable.
-Or having a lousy adapter between your laptop and the Ethernet cable.

I do not recognize using more time than with any other OBD tuning.

(Maybe the battery wasn't juicy enough )

Maybe, a flash can fail if certain parameters aren't met I.e. Battery falls below 11.0v in ACC mode. It's always a good ideas to have it on a battery charger of some sort, especially when coding. But yeah 2 min max for a regular flash.

Nice work VF Engineering. You guys are providing a lot of insight

Also false

Bm3 maps are 2mb btw

It also tends to be more credible when posted by a consumer (via independent
testing) rather than by a manufacturer who may or may not have skin in the game.

That being said, we feel there's more to the Features & Benefits / Pros vs. Cons
between piggy-back devices and a proper flash tune than just power delivery.

You mentioned drivability yourself already, and there's many more that are even
more subjective than that.

While I definitely agree that it'd be better coming from a consumer, currently we have nothing. I would definitely want to make sure the numbers look worthwhile before making the switch..

Also, can you PM me pricing info on the different stages. Is stage 2 compatible with a hatless DP and stock muffler?

It can be a nightmare depending where hes located and the internet connections. harkes is like on dialup speeds in China and he struggles alot

All good since Dzenan sat up an Asian server in Tokyo. It is serving us Chinese costumers very well

Before this I failed multiple times with the flashing and even "bricked" my car once so a full flash was needed - a tense few hours...

Yeah I dunno where that guy is from or what servers he uses, no way it takes 30 minutes to upload a map and flash. Uploading a map from my email to iCloud Drive to agent takes 10 seconds lol, flashing to dme takes 2 minutes. :

PM Sent!

Stage TWO is a non-highway / off-road use ONLY file.
It is indeed calibrated for competition use with a cat-less downpipe.

It has not yet been validated with the stock muffler as most of our
Stage TWO customers are using FULL turbo back systems.

[Zel335]

I sent a PM.

[wakeofdeath]

Any Mustang Dyno stage2 numbers?

So nobody is running small blends of E85 to increase the 91 octane into 93 ?

Where can this be purchased? And where in New England can I bring my car to unlock the ecu?
