Nope, and it's been about 2 years since the install.


I've also planned to do an ECU tune this summer, but after a not-so-good experience with doing one in my 430, I'm hesitant to pull the trigger.

Keep in mind that the aftermarket "drive by wire" systems are designed to mimic the response time you get when using a cable or "wired" throttle, as opposed to electronically controlled. FD certainly didn't trademark that name or idea. There are DBW modules available for pretty much every European car, made by various manufacturers. The technology FD uses, however, is definitely different than typical pedal boosters, as it is designed around the inherent characteristics of the F1 and ZF transmissions Maserati uses.

I believe the benefits are a reduction in slip during low rpm gear changes on the F1; and for the Auto, it's to remedy the delays in acceleration that Cybabar described above. FD is far too responsible to make claims of increased power or overall speed.

There is more to our products function and the benefits than what is being represented by *some* of the statements and comparisons that have been made in this thread. We do take advantage of specific Maserati behaviors in the programming to achieve our results that are unique to our product and we produce different enhancement modules for each Maserati model / transmission / software to get you the best results. There are certainly gains to be had from using the product that also make it a better performing product than you would find elsewhere. Thank you to those of you that have spoken to the merits and results of this.

We do not often market or tout a specific gain such as an improved 0-60 time or 1/2 second per lap improvement at the track, this goes for pretty much all of our products, even those where we have measured an improvement during testing. This is because we aren't selling to the Corvette C7 market (or equivalent) that may have bought the car to do drag strip runs or cut hot laps. Instead, we market the product as an upgrade that helps to wake up the car and provide an overall improved driving experience which is our main goal and isn't always measured strictly by drag slip times. Results can vary from car to car and will vary with different driving styles as well but as was previously said, owners feel the difference, they are happy with the results and we work hard to be sure that they enjoy the car with the upgrades we offer.

We don't suggest that the DBW increases peak engine power or increases your top speed potential but it's a really nice improvement for the Maserati that makes it a lot more fun to drive and helps the car behave much more like a proper sports car than a luxury car. As always if you have any questions, feel free to reach out to us directly and we'll be happy to help.

Best Regards,

OP here that started this firestorm!
To catch all up, cause who the hell has time to read 6 pages of responses, here's my intentions and reasons. I've owned a lot of fast cars, but now use an '18 M5 as my daily driver. It's an absolute monster and has jaded me to the nth degree. The Masi is a different animal, it's an exotic beauty, but which I especially now sorely needs more power. My initial request of 1 sec off the times was unfounded and I feel that the DWR upgrade will make me happier w/ the sport cats. I'm just looking for a minimal seat of pants enhancement, w/ the knowledge that it's normally aspirated and a GT by nature....
FD please PM me, so I can place my order.

Hardly a firestorm IMO...Just some back and forth...People can disagree and not be pissed...Seems like a lost concept these days...J

I thought I would be fine without this because Iím just into touring but now Iím thinking a Maserati needs to be totally responsive or why did I buy it. My wife will want to kill me but Iíll be giving FD a call.

Here's my exact quote: "My experience with the DBW was it did do what was expected (snappier throttle response) but it did not actually make the car faster."


You claim that it, with sports exhaust increases the car by 20 hp and makes it SIGNIFICANTLY faster. You are wrong.


You wanted FD to come and support your claim that it makes the car faster and they replied but did not say that.


You refuse to listen to some of the most knowledgeable and respected people on this forum (Jason, Catman) who are giving you their honest opinions and facts based on their understanding of how these things work.

Probably about the same amount of performance gain if you skip lunch or drive nude


Serious answer:
By remapping the throttle sensor you lose some sensitivity and linearity when modulating the throttle. For me I press the throttle based on how much I want to accelerate, not the other way around so I didn't find the remap all that useful. Some people like the car to feel like it's pouncing off the line with light throttle to make the car feel more powerful than it is. To each his own, all up to personal preference.

I think I made it clear that I used random numbers and that I thought DBW was a great thing. I was simply illlustrating that the claim of improved acceleration does not correlate to a better 0-60 time.

Quite possibly, but the ultimate answer would be 'it depends on what caused the lag' :(

For the avoidance of doubt I've only ever heard one person that wasn't delighted with the DBW. I've also got FD rotors and pads and the valve control kit. Not only are all those products great, the company is a pleasure to deal with!

About how much time should it take ( a professional ) to install the DBW ?

The Fat Lady Has Not Sung Yet.

Question; Does the DBW just vary throttle response or does it also choose shift points?

If itís just throttle control, (as put forward earlier) then I can see the argument that it may not improve 0-60 1/4 mile times but if it also changes the shift point it can certainly have an effect on acceleration times.

Given that weight, hp and all other things are constant and the only variable, at WOT, is the shift point along the engines torque curve, you can get different results. One old school strategy was to shift at a rpm that corresponded with 20% past peek torque, for example.

What are the optimum shift points for a WOT GT 4.7L coupled to ZF 6 speed? If FD has that algorithm in a can, it would be a can of ďkick assĒ in my book.
