AWD System

The car was used a prototype to find a way of uprating the Attessa system to past 34GTR spec by installing a  TSC which allows control of  lateral movement as well as the normal control of the split  to front  and rear drive. Auto stageas do not have lateral sensors like a GTR and the attessa ECU is not therefore equiped to control it. The 34GTR attessa is also much quicker to respond
The upgrade invloved the fitting of a GTR attessa ECU and then providing it with the extra signals.  We used a skylab TSC which has much better  four way digital sensors.

The ECU need 2 extra feeds for the skylab TSC  from the new digital speed sensors and the auto snow mode switch
The new uprated system means that  both the front/rear split and the way the car reacts to sideways movement is adjustable
The set up will also now repond even quicker than a 34GTR
The system has bee fitted to 2 manually converted stageas in the UK and both still work fine a decade later and give much better handling
. But to get the full benefit further changes are essential
