View Full Version : Fiat Panda 2008 IAW4AF

25th September, 2014, 01:17 AM
Hello there
I tried Reading the ECU Engine Data with MPPS which is from a Fiat Panda Petrol 1.2 8v 2008 IAW4AF.
Gives 320kb file, while the internet bins are 304kb...
I succesfully flashed it back and enrichened the mixture with winols but i get a dashboard fault light and with Diagnostics it displays "ECU Error"
I reflashed the original back and it works.

MPPS says it does the checksum automatically, but i guess it doesnt....
What tools do you use for this particular ECU ?

petrol engines...fiat....allways probblems....lambda,cathalizator,dpf,....stay away please with tuning this

Actually this is my car so i would like to play with it ;)
I didnt have any problem to enrichen the Fuels, its just the dashboard light showing an "ECU Error" right when i just turn the key on...
The MPPS has the IAW 59F option only for this Vehicle, maybe thats the culprit ?
It has only one Catalyst, with two lamdas and it goes open loop at full throtle.
See my wideband readings as stock

try galletto 54 to write

you worked and lambda map?

No, no need for lamda map, for me. Closed loop is fine @ 14.7 - 14.8
Played only with Fuel @ WOT and i got it a bit richer than i wanted ~12.3-12.8
But i was scared from the Error so i switched it to stock....
I also played with the Ignition but it is already too agressive from the factory... I already see ignition cut as it is....
Here is the stock avance after the 2nd or 3rd pull....

i think is a good result...diagnose with tester what said?

MULTIECUSCAN showed ECU Error, but no visible hiccups, obviously a checksum error....
Reflashed the original file and it worked without errors...

As long as I know the problem was using 59F option... CKS was wrongly calculated
