P0606 Saab 9-3 1.8T

[rob h]

Hello guys,

A 2006 Saab 9-3
55353231 S Trionic 8

Old ecu gave injector faults on all 4.

Owner bought exact same hirsch ecu.
Also with 55353231 S

After they match immo, 2 fault came:
p2228
p2257
Apperently there a 2 different engine, with and without these sensors.

(I could swapp old and new, carstill started with old ecu.)

So i took the data from the old ecu, and wrote that in the new ecu.
All seems ok, but P0606 comes quick, and car goes in to limp.


Both ecus have identical HW number.

Each ecu, with his own data does not give p0606.
I use Ioterminal to clone.

Are these ecus, different?


If needed, later i will post both files.

Any ideas, ??

Could this be a checksum issue?
I did not modify any data, i cloned full.
Will there still need to be a crc?
