General Re-Mapping of 1.3 Multijet

Yes, but -
How the hell do you get a picture of it? You can barely see anything from above, with all the airboxes and stuff in the way, and underneath (even if you had it on a hoist) there is a big plastic sump-guard to remove first. I can't see my local Fiat salesperson going along with this, somehow.

LOL, despite what you see on the outside, it dont show whats inside
How about telephoning Fiat customer services and asking?

No need to check that. 1.2 and 1.3 both have different Gearboxes. ratios would be too messed up to share a gearbox.
Parts manual.

Are we getting any nearer to solving this?
The EPER shows 3 different gearboxes for the three different engines - which is reassuring!!
The 1.2 and 1.3 boxes look pretty much the same in shape - just hope the diesel box is the 206Nm input torque box - surely it must be?
Unfortunately the FIAT part numbers on EPER bear no relevance to the gearbox type numbers on the 'Fiat powertrain' website.

The Diesel box needs the starter motor arrangement adapted. I have one sitting in front of me.

You have a Fiat 500 1.3MJ Gearbox sat in front of you?
If so, would you happen to know if it is a type 510 or type 514?

I showed this thread to the diesel development manager at FPT and it made him smile, what you fail to mention is increased smoke, fuel consumption etc. If this is a reliable, better fuel consumption route then why do FPT with the full development services of Magneti Marelli revert to VGT for the 90 PS SDE. Please also mention that your altered code can be detected by the dealer should they wish.

AJ69 - as you are buddies with the Diesel Development Manager at Fiat Powertrain Technologies - can you tell me what version of the gearbox is used in the 500 1.3MJ? Is it C510 or C514?
That might save me a month of enquiries / correspondence to Fiat Customer Service who will no doubt be clueless about THE DETAIL of their own products.
I am sure that your man is correct that a VGT engine is the best route to achieve these objectives - but since Fiat does not offer this alternative in the 500 - that is not much help.
It bears out what I said earlier in this post that the technical specification of the 500 1.3MJ is all about the best compromise between reasonable power / a low official CO2 emissions figure / good 'official' mpg figures.
Thanks,
Mike

My one is a C514.
I am glad that someone from your department is mentioning it.
i'm prety sure dealers won't have there cars re-maped because then you get into the "sale of goods" territory whereas you arn't buying the same car you test drove eg: test drive has 100bhp you'r new car 75 bhp when you expected and paid for the performance of 100bhp. unlawfull and illegal ( if they dont tell you )

Being new to this Forum I did not realise that we had the inside track to people at Fiat Powertrain employees. Perhaps those people can just confirm my understaning then:
Oldschool has a gearbox from a Fiat 500 1.3MJ and from the code number and the information on the Fiat Powertrain website we can see that the maximum input torque is 150Nm. That is therefore the lower rated version of this gearbox.
We also know that the 1.3MJ in the 500 has a 'torque limiter' in it so that the engine torque does not exceed 145Nm (a figure very close to the 'max' rating on the gearbox).
Questions for the Fiat Powertrain boys:
1. To a non-engineer like myself, those figures look like 'borderline engineering' - that is, not much margin of safety built in to ensure longevity of components. Fair comment?
2. Do torque limiters ever fail to operate properly? If so, given the figures above - what are the implications?
Some full answers would be appreciated and then I, for one, will draw my own conclusions about the pros and cons of re-mapping and will be happy to 'put this thread to bed'.

Anybody around from Fiat Powertrain Technologies today to answer the above questions please?
Mike
Mike
so this means that by re-mapping you'r 500 diesel to more than 150nm of torque you are going to kill you'r gearbox or seriously drop its life span... i bet re-maping companys wont cover you'r gearbox if the re-map destroys it in 5000 miles

Well - we are still trying to establish the facts.
I don't think we should be 'rubbishing' either the tuners or FPT until we have those facts.
Obviously the guys at Fiat Powertrain Technologies who are following this thread could not respond to it today for some reason.
Personally I would be very surprised if Fiat had specified a gearbox for the 1.3MJ with a maximum input torque so close to the 'limited' output torque of the engine - but you never know.
Hopefully we'll get some definitive answers tomorrow!
