I'm rewiring a GTR to eliminate the factory ecu and engine loom as its been hacked before and now the car is dedicated to targa/circuit duties.
I'm a little unsure as to what the attesa ecu is expecting to see in regards to inputs. I've read conflicting info on the net, but was hoping for a definite answer from someone in the know.
I've emailed Motec about it also.
I would suggest that you also try the Skylines Australia forums (http://www.sau.com.au/forums/) and look in the tech data there, if you haven't done so already.
Most of the signals for the ATTESA system are spliced into the harness pre-ECU so naturally come through as expected. The big one to replicate though is the TPS. I haven't needed to do it personally as I've either been dealing with plug & play solutions or full race cars where the ATTESA system has been disabled.
