Default Will the Adaptronic work without the stock ECU?

Will the Adaptronic function correctly without the stock ECU connected?

I asked this before in a roundabout kind of way, and therefore got no straight answer.

My Adaptronic is installed in a race car and I don't have any need for OBD2 or other emissions or diagnostic functions that the stock ECU might be needed to provide.

If someone could answer and save me the trouble of crawling under the dash I'd appreciate it.

For sure you will have to change the alternator to a NA alternator as the stock ECU still controls it. Outside of that, I would think you could make it work.

The eyebrows and eyeballs on your car definitely make the "happy" mouth look "less happy".

If you have an NB or NBB:
besides the alternator:

The cockpit is controled by signals from the ecu to the cockpit for the RPMs, the rest will work.

Last time I helped a friend to build in an adaptronic without loom it didn't, but I know that the info we found is given to Andy, and he used it for the loom they where designing at that moment.

A while after that: I orderd my own adaptronic with loom, and it worked at once.
