Hi All

I have been working with a friend (who designs small computing and
communications devices) on reprogramming the Sporting ECU map chip.
Initially this was just to disable the immobiliser programming but
after extensive web and newsgroup searching I have sourced a complete
chip mapping.

The work we have done also has the advantage of disabling the ECU
side of the immobiliser system, which means (subject to further
testing) that any ECU with this chip will work with any immobiliser.

I'm not sure that it completely disables the immobiliser. Further
testing is needed. I have been testing the chip for a couple of
weeks and it seems reliable but I want to test in different vehicles

There is one small issue with the chip which we are trying to
resolve. The "Code" light stays on (this seems to be a result of a
signal from the immobiliser). However this does not seem to affect
the operation of the car in any way

Two of my children have cinq sportings also (which is how I got
interested in the car in the first place) and I will test the chip in
their cars (but I cannot do extensive testing as they will not get
insurance cover for this sort of mod)

I have posted a performance graph below, so that you can see the results. This was obtained using a
Dyno Plus Road Accelerometer and is the average of two runs for each
of the standard and modified chips.

My car is a standard '97 sporting with no engine mods other than a
Ramair Panel filter. Further testing with a BMC type induction kit
is also planned

0-60 times and graphs will be posted later this week, but results
show that the modded chip reduces my 0-60 time by about 1 second on
average from 13-13.5 down to 12-12.5


So now the "ASK" would any of you cento owners be interested in the
chip (obviously for track or private road use as it will not have
any form of road certification) I have spent a fair bit of time
money so far and will need to spend some more of both to get to the
point where I'm prepared to let other people have use of the chip.
Depending on what level of interest I get I expect that a
contribution of about £80 each to join the project will cover the
costs (compared to at least £250 for a "Superchip" or "Starchip")

Given the uncertainty of a newly developed chip. I would expect that
contributers would wish to test a prototype in their own cars before
joining the project. This could easily be arranged if needed. I'm
not selling the Chip (for reasons which I hope will be obvious) this
would be participation in a joint development project

The chip could be ready in about a month, if there is enough
interest. I stress that I would not need any cash up front but would
be happy with a firm committment of interest. If it doesn't work out
to be usable or I can't substantiate the performance gain it will be
at my risk.

I'm happy using the chip at it is. It makes the car more drivable,
particularly at lower revs, gets rid of the flat spot and improves
acceleration considerably. If I get enough interest I will test and
develop in further but I can't afford the time or justify any more
cash on the project without knowing I will get some of it back.

If anyone is interested in testing the chip let me know, I may need
some help in return for a reduced contribution. Also if anyone has a Punto 60 throttle body to loan, sell or exchange this would be useful for the testing programme.

Let me know what you think.!!!!!!! You can email me at
[email protected], or post here.

Sounds good! Judging by the graph, is the rev limiter set lower? just the values for the new chip looks like it cuts at about 5800?

sounds intersting,especially at a tight scotsman friendly price.

The Fiat Cinquecento
Fun While It Runs

Very interested, have to have a look at how it affects fuel economy and engine wear but i don't imagine that to be a problem, i have a Sei but am i right in assuming it would slot stright in being the same engine as the cinq? or are the ECU's different?

Depends on SPI and MPI engines, also the cinq had 2 versions of ecu, one without immobiliser (upto N-Reg) and those with immobiliser (N-Reg upwards).

I'd be interested in helping develop this and commence testing

if you woul like to do a MPI model of the chip im always willing to help but need to use my everyday car for work!! so would have to be able to use it for everyday use

I would be extrmely intersted in this, yet again for an mpi model sei though. Would be happy to help do some development though.

Magnecor, K & N, Bosch, Peco all buzz words of my sei!

a spose a wudnt mind testin it mine wud need to b a SPI seicento sporting one and i need it everyday aswell but will to help out

Wen in the toon slow it down, out it the sticks give it the licks!

Hi All,

Thanks for the encouragement, I'll continue the work and will post up the performance data at the weekend. If you're interested in testing you may want to have a look at your ECU.

Firstly to check that its a IAW 16F ER the chip will only work with this ECU (for 1.1 spi engines)

Secondly to check inside to see if the chip is socketed most cinqs are but mine wasn't and its a tricky job to put a socket in. You may be better off getting an ECU from a scrappy rather that fitting a socket
I wish I'd known that the chip would work with any ECU before I paid to have a socket fitted.

Also if you want to help with testing Email me [email protected] so that we can make arrangements

Can you put a mapping for a Punto 75 on the chip too (as I have a 1242 with PUnto 75 cam etc and a tuning chip for Punto 75 should work good)?

Sounds good to me! i am interested! [8D]

The cinq will return

Sorry I don't think I would be able to ut a punto map on. I think its a completely different ECU. In any case I'm busy enough with the sporting ECU

i'd deffinitely be interested - don't mind any experiments being done on the wee bugger if it makes it better
