I intend to use the original housing from a second ECU I bought on ebay.

Hello

Nice looking adapter plate,

I just realist that I mad a minor mistake on the Drawing of the bolt plattern i posted in this forum.
One hole diameter was not corect.

Oil pump flange on the transmission,

Today i measured the bellhousing bolt pattern.
For those who want to add a third mtor or want attach a ICE as Range Extender or want to use the transmission as e-CVT.
Accuracy should be within 0,02 mm.
