JFiat  Fiat Panda 900 2014 ECU IAW8GSW Knock Sensor In The Map
Hello everyone, I have a problem on this car, Fiat Panda 900 TwinAir with electronic Marelli (IAW8GSW) Petrol/CNG 2014, on this car the following components have been changed:
With motor grinding head is new valves, changing the turbo (new), complete electrical system management engine, all sensors including the detonation sensor and in the end also the probes remains only the engine control unit to be replaced. My question is, you might intervene in the map by raising the percentage of detonation, or by identifying the curve of Herz transmitted on the sensor to change the reading? The machine is good for 100 km then it goes into recovery engine light off but diagnosis has P0325 error.

We attach the original map and see who is able to identify these curves is perhaps advise me what to do to make sure that does not go into recovery with 0 errors in diagnosis.
Thanks to all.bow

We also had knock sensor problem with such motor some month ago, fiat told us to flash new software to ecm but we didnt have update for this car via witech. there were recall for some twinair with this failure. Fiat made special flash procedure (remote via Team viewer), now car runs fine and no problem anymore. (i work in a Fiat workshop)
