I was wondering if anyone has used a stock 5-sp ecu with an automatic. Would it help you or is it even feasible or good for the car?

 

I think it's pretty obvious that you can't do this

 

I woodn't

 

you could BUT you would loose all the electronic control of the AT - also I think the connector is physically different (not just electronically) so the 5spd ecu won't just plug into the AT harness (and vice / versa)
