Hello, I would like to try installing the M50 intake manifold on my EURO 328i M52B28 to gain a little power, but I will need to reprogram the ECU. I currently have a Siemens M41.0
Official Number: 1740497
Software Number: 1427732
Assembly Number: 1427731,
(normally in OBD1), from February 1995, and I was wondering if my DME is flashable ? (NOT AN US VERSION)
I did not find any information about which units were flashable with a cable and which one needed to unsolder the EEPROM.
If mine is not flashable, wich DME should I buy to flash it easilly ? thanks !
