156 data analisys

Ciao Alfistis,

My ride is a CF3 1.6 156, ME731 electronics.I recorded some data from alfaobd, and made a graph from it

I've been struggling with the usual low power/misfire when cold. Am i seeing correctly, that the third lambda (below cat) is catching up a bit late? For about 500 secs it looks like sleeping.
Replaced all three about a year ago with genuine BOSCH 258006376 and 258006388.
I had immo issues earlier, and i had to reflash the ecu (the immo box itself broke somehow). Unfortunately, the one worked was for a 0261206707, which is for the 2.0. (the 1.6 ecu is 0261206716) can i have problems with this flash? I mean did i accidently chip tune the car? I didn't experience any extreme power or consumption differences.. don't want to mess up things anyways, the engine just got rebuilt, after 250K

thanks for your replies!

the 3rd lambda should be showing a rich mixture at all times except when coasting. if the 3rd lambda follows the other 2, the cat isn't working.
