The very last production year/month of MC Stradale

[midlifecrisis]

What are the graphs showing?
Eb

The red line is the engine torque and the dip is an indication of it being cut to allow the changing of the gears.

Coppia Motore = engine torque
Regime motore = engine speed

Not forgetting that the “proper” Strads have no rear seats, and the fronts are the light weight carbon jobs from the Enzo and MC12.

but sadly offset by heavy cast wheels, no carbon fibre bonnet and lower power output.....

From one of the numerous docs on the Granturismo there's this oscilloscope picture. I think this is for the 2007 onwards 4.2. View attachment 75905View attachment 75904

But this is neither MC Shift or Strad, so is this for ZF box?
Feel free to correct me.

 

[gb-gta]

They should have just given the stradale a good old manual box with 3 pedals, then all this 2 pedal confusion would be irrelevant!

 

[Ewan]

So, let's get this straight, MC Shift GT S 4.7 v Strad what's the difference with the transmission?

As far as I'm aware, the key difference is in the software, allowing the Strad (in Race mode) to have the fastest shifts.

You say that, but I see from the brochures that the official combined figure for the 2 seater is 19.6, as compared with 18.2 for the 4 seater. So there's a price to pay for you guys that are dragging around all that extra weight!
(and that's before you put your guests in the back)

On a related issue, given that the extra 10 horses on the later cars came from a software upgrade, can this be retro-fitted to the earlier cars? (Not that I'm sure I'd notice, but it would be nice to know whether it's even possible.)

I'll ignore the banter about the seats ...
However yes, the ECU can be re-mapped for the extra horses that yours is missing. This has done before and discussed previously on here for GTS 4.7 owners who did not really notice any real world difference.
On my Trofeo, the map that was written onto the ECU (which is a stock ECU, the same all 4.7 GTs) was written so as to force in more fuel as quickly as possible to optimise the car for racing, but it was reading around 430bhp. I had DMS in Southampton remove the race map as the emissions it was producing were through the roof and a real problem for the MOT, and they added their own 4.7 enhanced map onto my ECU, and further tweaked it when it was on their rolling road. It is now running considerably cleaner than it was and is producing 505bhp

My old GTS MC had the 599 GTO TCU firmware. That was bloody quick and very smooth.

But seems it's impossible to find anyone who can perform the upgrade?

The actuator is different, which is the key to the faster shifts. Std MC actuators have a neutral position so the TCU gear change process is paddle - clutch - disengage gear - check for neutral - engage next gear - clutch. With a Strad it negates the neutral position.

I suspect the reality of the higher fuel consumption may be more related to tighter compliance (and perhaps reduced lunch expenses for those entertaining govt officials coming to check on the data - clearly there was always enough to deflect the man with the db meter checking exhaust noise levels! I for one am very happy that this took place; greater flouting of the rules have not been seen since VW software engineers reverse engineered the exhaust emission devices!),,,,Allegedly.

Well, in any case I would not have been able to buy a Stradale if they never produced the 4 seat version. I am glad that they did add the 2 seats back into Stradale in 2013, otherwise I would not have been able to enjoy the car driving to the Netherlands!

I have never come across any 2017 Stradale, has anyone seen any before? Well, mine is September 2016, so probably the last few real Stradale that left the factory, so even more reason as a keeper then.

Higher Power in the later cars also came from a finish applied to the cylinder linings.

 

[Ewan]

Spoke with DMS. Their re-map gives the road Strad 487 bhp, up from 444. That sounds enough to be noticeable, and therefore interesting.

Yeah, and assuming similar results might be had on the GT-Sport.
I know there are past threads about this from years ago, and the general thought was it made very little difference.
I'm always dubious about these claims unless there are before and after dyno sheets, and preferably from someone that didn't do the mapping.

Also, if the extra power is gained by just upping the rev limit by 200rpm, then its a bit pointless. If however there is a 40hp gain across the whole curve, it should be noticeable.

Where is the QI klaxon when you need it!

Yes, I think that's true. Shame. Not sure what happened to the chap who did mine. Maybe Maserati caught up with his illicit operation to improve their cars and whacked him. Improve perfection? Heaven forfend! Never tell an Italian how to do something better. ;-) Or, more likely, he jacked it in and retired.

The good news is that there are enough people on here who'd like to get it done so I'm sure if someone can figure it out they'll spread the good news.

This was the dyno readout from DMS after they had my Trofeo for an afternoon.

Well, even Maserati dealer does not know the difference between a Granturismo MC and MC Stradale...

or maybe the misrepresentation is deliberate...

If 490-500hp is easily achievable with just a remap then that makes me sure that Ferrari were deliberately holding back this car more than I thought they were. I also heard that the 4200/GS can reach 430hp with tune and exhaust work but have seen no confirmation.

Why didn’t the GT get the twin turbo V8 from the QP6? It would’ve made it more competitive especially later on.
