Cinq sx 500 (900cc) ecu stuffed

Hi folks new on today hoping for some help

recently aquired cinq sx 900cc, drive it from mid lincs to mansfield no probs a couple of days ago, 2 keys supplied (standard ignition keys) no others red blue or remote keys/fobs.

i have stuffed up my ecu by thinking i could program my infra red watch with it ( i use it to open central locking on a citroen zx so why not any other)
and i think my ecu has taken umbridge at this and gone tits up.

my present ecu part number is IAW 6F.SO fiat 500 on an ecu list website this comes up as for a fiat cinq 900 sx with all the same numbers and letters that my ecu has but i have been advised that if it says 500 on my ecu then a another 500 is what i must replace it with, the fiat 500 on this list has a different part number
http://www.peacockandpurvey.co.uk/fiat_ecu_list.html

questions
1) replace ecu but does it matter if i replace it with a 500 or 900 my cinq is 899cc
2) to decode if poss (pre 95 cinqs do not have red keys or key codes)
3) is it possible to have one of its chips replaced with something that can get me going.

i have been ringing round several places already inc fiat and they all seem a bit befuddled as to what has happened.

advice will be appreciated
many thanks
Tram Man

1)It says 500 on the ECU as italian for 500 is 'Cinquecento' . just a short way of writing its name! Replace with another Cinq 900 6F ECU!

2) No decode needed, just get another 6F ECU...AFAIK only the 16F Series of ECU (Cinq Mk2 + Sei) is coded.

3. Doubt it. But are you sure its the ECU thats fried?

Does the warning light (Thing next to the battery light) come on and go off (after 4 secs) once you turn the key to the accessories (not start) position?

Re: Cinq sx 500 (900cc) ecu stuffed

Hi Tom
thanks for your input, in answer too your advice yes i think my ecu is fried cos everything worked fine until muppet me did some reprogramming.

the warning light does not come on at all, the injection comes on for a few secs then goes off.

some clicking noises from relays under passenger dash (central locking ones as when i remove c/l not operate)

also ever since purchase a little red light keeps flashing on dash hand book says something to do with alarm but this car has no alarm fitted that i am aware of, prob cos someone has taken it out along with roof sensor.

thanks again
Tram Man

Re: Cinq sx 500 (900cc) ecu stuffed

I've got an ECU from a low mileage 1994 900S. It's not coded as it's pre code; it will work with any 900 and I believe the 1100 also.

It was working 100% and is guaranteed as such. The car had covered 50,000 miles.

If you are interested make me an offer via PM.

Cheers
JR

Re: Cinq sx 500 (900cc) ecu stuffed

ECU issues aside for the moment, does the car have R/CL from the key or fob? Did you try to "grab" the signal via your watch?

Don't know of this would have wrecked the ECU TBH.

the cinq doesn't have an Infra red reciever, so what were you trying to do with your watch? if it did have a reciever then it has an aftermarket alarm fitted? which wouldn't stuff the ECU it would stuff the alarm.

Try disconnecting the battery for 1 hour then reconnecting it.
This may reset the ECU.
