I have tried but haven't had any luck so far.
The ecu hasn't been very co-operative so I'm not getting anything out of it - not even getting the signal/light when you turn the ignition key on.
I checked the TPS and it isn't giving the closed signal to the ecu, so I have a new one to go on today/tomorrow. Hopefully that will enable the ecu to give me some outputs (but I'm not very hopeful).
Also, it could have something to do with the "Neutral" signal that the ecu is supposed to receive - my car has a Ford auto transmission not the Toyota standard one, so that probably isn't going to help.
