Took the plunge yesterday and ordered a 1.3MJ Sport (well, under threat of divorce if I didn't).

Has anyone had one of these re-mapped yet. The claimed gains (+25bhp and +55Nm) are pretty significant and must make for a much quicker car.

Be interested to hear from anyonewho has had this done.

So far I think theres just one thats been mapped. The demo car for nouva500shop.com They say the increase in performance is massive.

Wow, +25 horses, an impressive gain. Does the 1.2 remap achieve anything like this? And how does this affect the fuel efficiency (1.2)?

Thought they mapped to about 105bhp

!.2 is a petrol and won't show as significant improvement. If you want to see the difference come to the rr in Watford and we show you what can be done.

The 1.3 does indeed have a good strong gain, we have done over 8,000 miles of development tesitng in ours with various levels of tune and have settled with maping of around 100bhp and 155lb ft, giving great fun performance and imporved economy. If you want a demo, please drop us a line and we can take you out for a drive first if it would make you happier about it.

We have just taken delivery of our own 1.2 which we will transfer all the original 500 1.2 testing from late last year onto and then set about doing the same rigerous test and development work on. We have already done half a dozen 1.2's which haven't had any issues and all show good performance and economy results, however there is nothing like having your own car to rip into.

We also have 1.2 exhaust systems and induction from ITG available for them and have a side project on cams and heads underway, but wont release that until later this summer on a special edition.

We have heads and cams already tested on the 1.2 as well as on the 1.4. Induction is available with proven results for either car.

I too have a 1.3 Multijet on order. I have never owned a car with as little as 75BHP before so very seriously interested in this re-map.

Please can you tell me
What happens to CO2 emmissions and road tax?

Your CO2 emissions and road tax are done on the type not the individual so they stay the same . There really isn't any downside to mapping.

So there is no downside whatsoever to having a car mapped above its original power levels?

Nope , you get improved drivability, better throttle response, safer overtaking and more mpg, which is why even dealerships get their own cars done, fleets managers get them done and even Ambulance services.

Thats fantastic news about CO2
Do you have any torque curve or BHP curve graphs following re-map? or any details of torque/BHP at other revs (rather than just maximum).
I was pleasantly suprised to see that the standard 1.3 has more BHP than the 1.4 up to (and just beyond) 4,000 revs already.
I'm sure the re-mapped 1.3 torque/BHP curves will look very exciting.

Yes of course, email us on [email protected] or if you fancy a qucik spin this lunchtime I am not far away.......

Why does the 1.3 Multijet have less torque then the engine available in the Grande.

Fiat 500 - 107 lb ft

Grande - 140 lb ft

Right before I start I want it made clear I am pro remapping. Every car I will ever own will be mapped and tuned.

However there are disadvantages, engine life will be reduced not by a massive amount but it will be reduced. Also warranty will be invalid. Granted the company doing the warranty work will not look for a map so will never know and even if they did it would not be in their interest to notify Fiat about it because it is likely the work would then maybe go to a cheaper garage if the owner of the car has to pay for the work themselves.

Again I can't stress enough how pro remapping I am not just on dervs but any car that can take a new map. However I am even more pro that people have all the facts available.

Also what dealers have you mapped cars for? As I'm sure that it is not good working practice to do test drives in cars that do not represent what the customer is likely to be buying.

I'm sure torque is limited in the 500 the same way it is in the Panda. Something to do with the gearbox I'm sure I heard.

So how does that work with a re-map on the derv then? Can't be good can it?

On the face of it no it wouldn't. But what I have said about the gearbox is just what I heard and by no means confirmed fact.

OK, firstly regarding the torque difference, the 500 has a limiter as does the Doblo, we have tested the removal of these and the Doblo has now done 92k without an issue. The gearbox is made of the same material so there isn't any reason why it shouldn't be as robust and after all we are not talking 300lb ft here, only 50% of that. However, one of the reasons we bought the 500’s is so we can do the testing on them, so we gain first hand knowledge of something as far as possible and can test out any weak points. 8k in and no issues and this cars output has been up and down like an Otis , round and round a track and spent hours on a dyno and hasn’t murmured once – they are pretty robust, not some flaky poorly made car, they are probably one of the best built Fiats ever.

With regards to dealership tuning, I shouldn't have mentioned that really as customer confidentiality is the same for both trade and private alike. Most tuning companies do it, we are not unique by any stretch. The Ambulances were for St John and they have given us the go-ahead to name them as they appear on some of our advertising. They have asked us to return and do their latest additions too – which is very pleasing and shows that even with 2 ton of additional weight the standard components are up to a daily hammering on most vehicles.

For engine wear the fact is if you treat your car with disrespect, regardless of any tuning work carried out, it will wear out quicker than it would do if you treated it with respect. The main cause of wear and tear is the unique part that attaches the steering wheel to the drivers seat....

However you look at it, the standard torque of the 75BHP 1.3 Multijet is 190nm in the GP and downgraded to 145nm in the panda and 500.

Nothing wrong with that, but i can`t see a commercial advantage to Fiat in doing that if the gearbox would take the standard torque as fitted to the GP.

The Panda box is seemingly only 5nm below max torque rating and it seems likely the same box is in the 500 or they would surely have upped the torque as standard.
I`m writing this because i think it would be a shame to reduce the service life or risk sudden gearbox failure on the cars when they are so good as standard.

Would any of these tuning companies give a written warranty to match Fiats, 3 years and 60,000 miles on the gearbox after they have upped the torque and invalidated the manufacturers warranty on the box?
