The design criteria is: to plug into the OBDII test plug, download and restore the stock program repeatedly; be able to upload and retract 3 (ea.) modified programs into the ECU.
Forgive me my ignorance, but it all sounds like russian to me..
Can somebody explain me what this is all about,
1-what is it
2-can you do it yourself
3-what does it look like/is it big heavy
4-any negative aspects

Sincerely,
your Dutch friend
