Has nothing to do with PIS settings.
When you drive your car hard, full throttle, high revs when changing gear, the shift is fast.
If you do the same with a lighter throttle, or lower revs, the shifts are slower.
If you read the owners handbook there is actually a section that explains this and rev limits when this takes place.
All the DBW module does is trick the gearbox ecu to thinking the throttle is fully pressed and the engine at a higher RPM for the faster shifts.
Therefore if you drive your car hard with the DBW module it makes no difference whatsoever, it can't speed up what is at its fastest already.

Hi Scott, I can highly recommend the difference the DBWEM makes.
I found with the standard software, if you were in neutral at the lights and grabbed for first, the car would have a committee meeting then select first.
I lost a number of drags that way against stuff I should have hosed, as it gave the other guy too much head start. ( Red Italian cars make some other drivers get all feisty ).
The DBWEM also increases throttle response. The PIS adjusts the clutch take up point which is a different thing.
Gear changes at full revs were always faster with the standard software. The DBWEM brings this into normal changes.
There is a secondary setting, race mode which really slams the changes, but I haven't used this. Unfortunately to you have to turn the engine off before switching modes, which makes it cumbersome at the traffic lights. I once had a guy in a turbo Volvo sedan reach across to his glove box to activate something in his car, then it went really hard.

It's basically all a fudge.
My BMW like most has comfort and sport settings etc.
All the sport setting does in mine is make the throttle movement less so you push it a bit and off you go, giving the illusion it has more power.
It also makes the steering heavier, which is totally daft in my view!
Eco mode the opposite, you push the throttle and nothing happens!!

Will the module turn a GT car into a race car. No. I would add, imho, the module makes most sense at lower speeds/revs. Particularly around town where clutch engagement and, therefore, usability is transformed.
^^ This. I don't use the faster of the two settings either which, agreed, is noticeably more aggressive.

Thanks folks. I don’t think at full throttle it needs anything, but low speeds I’m looking to smooth out the gear changes / quicker changes.
So does this module effectively enhance the sport mode further at low speed as I tend to drive it in sport mode all the time?

I think the general consensus is the American's swear by it, the Europeans slightly sceptical. Maybe is cos they go from auto down to robotised clutch and paddles and we go the opposite, more perception and driving experience than anything else.

They are different things, setting the PIS is fundamental to the car regardless of what you have on it.
As for the DBW, my car came with it unbeknownst to the previous owner, I never drove an unmodified car so I have no point of reference but it seems pretty good for what it is. Although if you can pull the strings and get the TCU reprogrammed it will be a better option.

Yes, I heard the Ferrari 330 (I think) TCU firmware is the daddy!

I'm personally sceptical about what they change between the different year models, other than the cost they charge and then putting it in a new box.

360 CS
You have to be a member of the illuminati to get it done though!

Highly unlikely there would be much difference from a 2005 4200 to a gran sport

Its a tight held secret, not sure why but things would be a lot different if it was widely available.
The guy who does them for the 360 Modenas will not touch a 4200 and change its parameters.

Is this the guy that has done a few, but not anymore, or someone else?

He’s a guy in France who’s active over at ferrarichat i believe.
I think aldous from AV engineering might do them since they’ve done a lot regarding decrypting the 360 Modena computers.

Forum "opinion" always vary but always best to form your own. If you can try before you buy even better.
The short answer is yes. Although not limited to sport mode. This characteristic is exactly what I like about the module. Maserati's interpretation of F1 software in later Coupes was deliberately "soft". The module addresses this. It turns an otherwise cumbersome gearbox at low speed into something very different. Not as harsh as a 360 CS which, imo, makes the module better suited to a GT car.
