320d software in 318d e90 ecu

[Mr Mpower]

i have a 318d m47n2 e91 from 2006 with 122hp, and i know the engine from the 320d m47n2 with 163hp is the same, but have bigger turbo and injector...i have installed in mine..and i need to know if i can upgrade de 318d ecu via winkfp to de 320d version, it is possible? is a simple upgrade?

thanks guys!

[Mr Mpower]

i think im close, by now i know 318d is dde603 and 320d is dde604. and if i try to put dde604 version in my ecu he shows wrong hardware number..
i need to change my hardware part number or force winfkp to flash the dde604 version on the dde603.

Depending on the hardware, there may be a good chance of corrupting the dme. Make sure you have backups.
If not, get a proper tune.

yes, i know, the only thing for think on it is because there are exactly the same engine..and maybe exactly same ecu with different software
