348 ecu upgrade

[nunojcmaia]

hi all,
I read on this forum that QV London is offering an ECU upgrade for the 348 that gives 15 hp power increase. Is that true? Is there anybody who have done this upgrade before?
And you can feel the difference between 300 and 315 hp, I mean in road use ?
Thanks for your help.

Nuno Maia.:huh:

Haven't had one fitted, but I understand you get a mild improvement in the mid-range.

From the QV website:

"ECU Chips 12-15 bhp increase £410.00 plus VAT"

I suppose a 15 bhp increase would make the car feel more like a GTB/GTS/Spider that has 320 bhp. Have'nt driven any other 348 other than my GTB, so can't really say what the difference is.

When i bought my car,i had an invoice in the paper work for a Hammon chip upgrade on my 95 2.7 355. It was for a few grand and was done in 2002. I do know that my car is more powerfull than two mates 98 and 99 5.2 355s. But it may not be a fair comparison becourse his is standard with a standard exhaust system. Were as mine is a De-cat Capristo with K&Ns. So i can only say that a chiped and De-cat Cappy with K&Ns is more powerfull than a bog standard 355.
Bellow is my car (red) and one of te standard 355s.

Thanks for your replay.
I realize that nobody can assure an ECU upgrade makes a lot of a difference , and I don't want to ask the parts supplier !
Perhaps you can't upgrade a Ferrari like you do on a toyota, ford or other cars....

Of course ya can but you will need a sh*t load of money and get it done after market:thumbsup: Thats one thing that i like about Porsche, if ya want a couple of hundred bhp, ya go into a official Porsche dealer and throw money at them and ya got all the bhp ya need. Ferrari are up there own **** on the subject of tuning, they think the car is fast enough:cry: I dont:thumbsup:

I used to be very sceptical of ECU upgrades, and I believe rightly so up until about 2002 or so.

I have now seen and carried out enough to feel there is a gain.

Mostly, the gain is in "tidying" the mid range mapping, for better throttle response and optimising for better fuel quality. Some cars respond way better than others, and some brands of "chip tune" have good or bad feedback.

Turbo cars with electronic boost control are ABSOLUTELY up for a chip tune, but normally aspirated cars only gain relatively small amounts.

I'm lucky enough to have an independant chip tuner just 3 doors down from my shop, and he picks and chooses which suppliers software to use. It seems ideal and I'm happy with results.

I do think it's expensive, as software is just software, and I know how hard I work to make what a chip tuner charges for a quick "flash"...

but we all got bills to pay.

I'd strike a deal with your tuner... go to a dyno, test the car standard... not just full power, but do some part throttle work too...

then re-test it after.

If there is no gain, or not what was estimated, then haggle....

Superchips do an upgrade for my twin turbo Maserati Ghibli which gives +30bhp according to their information. What level of risk is associated with chipping a car at that level?

[Kenyon]

I had a maserati 430 V6 twin turbo.
I up the power from 250 BHP standard to 400 BHP.
I up put larger turbos, added a fuel boot regulator, ECU upgrade for the ingition system, introduced two larger intercoolers and bypassed the turbo boost management system, by inserting a three way valve into the pressure pipe that connect to booth turbo waste gates. Basically this allowed me o over boost the system without it shutting down. The rolling road reading was 4005 BHP at the wheels. The only problem I had was the Differential was unable to handled power above 400BHP. I tracked the car several times and blew the diff once twice at donington down the craner curvers. If you had power on at full throttle in first and second the clutch would not last long. I was getting flames from car. The car would wheel spin in 1st, 2nd, 3rd and 4th. A awesome car, shame about the build qaulity. its rusted ever year, so had to go.

The 330 BHP standard maserat bi-turbo 'CUP' engine of yours will handle 550 bhp. I have a test report from maserati in italy that showed the engine was good for 550 bhp but was detuned to make it more effecient on the roads.

The 'Cup' engine was used in the race series for two use at 330 bhp from a 2.0 ltr V6. In the two years of racing the engine never blow up once. That is official from Maserati. Was documented in many mags. One of the best engines all around. Bullet proof. The main issue is ensuring the gearbox and diff can handle this massive powers of 550 BHP.

I love maseratis..... Especially the CUP.....

Thanks for the info - mine isn't a Cup though, it's a GT, which means 2.8 litre / 284BHP instead of 2.0 litre / 330 bhp.

Still like to hear ferrarifixer's viewpoint too.

Not really. I now when I am cruzining on the motorway around 60-70 mph its getting about 30 MPG to gallon or their about. I know the 348 manual states about the same figure. Normal country road and town driving usually in 2nd or 3rd gear all the time (TUBI noise love it) much less. I don know from having my Maserati the fuel consumption is very good on the ferrari. I used to watch the needle drop on the maser.

:thumbsup: Thumbsup for having a Maserati Ghibli GT what a great car. I think they are better then the 3200 GT. More drivers involvement. Would love another maserati but the Maserati Ghibli actally costs more to look after then the ferrari. It would be nice to have both. My wife loved the maserati because it was understated but had the massive performace. Maserati Ghibli will be a classic to own one day.

Considering your uprated power, that's an excellent result. Anything mid-20's mpg is great, the 348 lump is certainly Touring friendly. Recently had the Tubi stuck on mine and it definately makes a difference.
Can the Dimex work carried out in the UK ?

I am not to sure about the work being carried out in the UK. I was led to believe their was a DIMEX AUTOMOTIVE distributor in the UK.

Check out their website.

www.dimex-automotive.de

I can e-mail the brochure if you wish. Its in english but prices are in euro's.

Chipping a normally aspirated car has no disadvantages below the std rpm limit.

Raising the rpm limit will obviously stress all moving parts more... exponentially too. Some engines can take it better than others, and if you dont spend much time up there, you'll be ok. But I wouldn't raise the rpm limit on a racing 360C for example, as the std pistons are too heavy for longevity.

Chipping a turbo car has more risk. Usually things like head gaskets in normal use, and drive trains too... but the gains are mostly huge in comparison, as boost is easy to get.

I'm gobsmacked the the 355 twin turbo car here in melbourne hasnt lunched itself yet. I know he drives it hard enough, and doesn't care if it does either... but it hasn't.

I haven't chipped any Maserati's, so can't answer from direct experience.
