D2 1999 TD5 Auto ECU Change

Hi,

I have a D2 1999 TD5 Auto with a MSB ECU.
I am looking to remap and ECU and be able to program the ECU.
My question is, from what I have read the MSB ECU's are non programable, but the NNN ECU's are. Is it possable to put a NNN ECU in a 1999?
If So what do I need to do?

Many thanks

You need a nanocom to pair the NNN ECU with your vehicle then remap it with a proper Eu2 fuel map which you can buy online as to be loadable with nanocom, example http://www.alivetuning.com/product/nanocom-remap-for-td5/ but there are others too

Excellent Thank you
