"Dear Henry,

Thought you may like to see the performance figures for my re-mapped Maserati "Coupe Cambiocorsa".

In July 2007, my Coupe, a 2004 specification model, was re-mapped by the only specialist in the UK with the correct programme, sourced from Italy.

It was done over a half day on their full rolling road "DYNO RACE" dynamometer. The car was tied down on the rollers, with huge tubes from the exhaust pipes feeding to an outside dissipater on the roof of their premises, and was done in a controlled, soundproofed, sealed room environment.

The re-mapped details are listed below:

Engine Power: 459.5bhp at 5,960 RPM
Power at the wheels: 320.8bhp
Dissipated Power: 138.7bhp
Correct Power DIN: 459.2bhp [DIN 70020]
Torque: 439.5 lbs/ft at 4910 rpm
Atmospheric Pressure: 1002 mbar
External Temperature: 13.4°C
Final Ratio: 4.4 to 1
Tyre Size: 265/35-18
Total Ratio: 2.1
Tyre Diameter: 643mm
Test Gear: 4th speed
Acceleration Time 4.7 secs
Date of Test: 12/07/2007

During the day, a top speed test was run, in which the car achieved a speed of 191mph!

Thought this may interest your many readers!! Incidentally, the car also runs with fast road brake pads, to help the overall braking performance, which heat up better on public roads than full race pads would.

Yours,

Peter."

From an enthusiast in the USA:

"As far as the remap is concerned, 50-60hp sounds like a heck of a lot. I, and many US-based owners of modern Maseratis, have used a performance "piggyback chip" from Formula Dynamics, a well trusted tuner. And their Dynos indicate about 30 hp improvement at peak power.

The other thing is the fact that I did read on the US Maserati forum that the stock ECU is virtually unwritable, though it can be read (and different inputs to it provided by a separate chip, as per the Formula Dynamics' performance module). I find it a bit hard to believe the viability of a remap."

"Henry,

Thought I better make it quite clear that when we first set up my car on the Dyno, we checked out the standard performance of it first, and it showed 413.2bhp on the Dyno, instead of the 390bhp quoted in the car's standard literature, we even checked it twice before believing it!!

We then phoned Maserati UK to ask if this was unusual, their answer was NO, it is around the 390/410 average for that model Coupe, but it was one of the higher ones they had heard of, they said it must have had a good builder on the day the engine was built!

So, raising it to 459 was not such a stretch, as it was NOT from the original literature quoted 390bhp, but from the cars own 413.2bhp starting point, so it was only an increase of around 46bhp, which is around the average for tuned Coupes!

As for the US owners saying it is hard to do, we agree with that, as NO ONE else in the UK had the correct programme to enable them to do this conversion, it took me quite a while to find the correct people with the right programme!

It was a Maserati Programme from Italy that they used on my car, and I have never had a days problem since it was first done, in fact with the huge torque available now, my petrol consumption has gone down, and my car now averages over 21mpg, rather than the 17/19 it originally did, even with the extra pulling power!!

Regards,

Peter."
