ECU part number 55181152 is specific to the Fiat Palio and is not listed for any other cars. The Palio was not sold in the UK so you are unlikely to be able to get one here unless ordered from a Fiat dealer.

If you decide to buy one from a dealer, they also list a reconditioned ECU which may still be available as part number 71784986 for about half the price of a new one.

The price for new ECUs:

71784986 - 527,10 €
55181152 - 918,06 €
 
My car has teh same problem , 2 cyclinders not firing , not sure if its teh ECU issue , local mech told me to replace CKP sensor , did that still no luck , i just hope its not the ECU problem am doomed if so ,

am just worried about this now
 
The car diagnost can make the decision if this is the problem of the ECU during 5 minutes.
It is only need connect oscilloscope to the ignition coil control pin.
 
Hey guys dont know if i can help? I have 2 ECU's from MK1 puntos. These are SPI (single point injection ECU.s). They come with ignition barrel, key and immobiliser box and ring. £75
 
Hi did you ever sort your problem out? I have the same problem with an ECU the vehicle is a Seicento SX 2001 ECU number, IAW 59F.M7/HW004/3502-751. were did you get your new ecu?

Tjur what trace am I looking for on the scope and do I just connect it to the ignition coil wiring?
 
hi
2 pistons not firing??Checked spark on all 4 plugs-100%.Injectors checked and found 100%.Pressure on all cylinders ok.ECU was reset and seems OK.
If 2 injectors on the left are disconnected engin runs the same.If one of the two on the right is disconnected the engin stalls.
Diagnostic check done-everything checked but still we do not know what the problem is.Can not replace ECU for the cost and just hope it will be fixed.
Need some advice or info that can help.
