Nope, T5.5 is a 2-wire VR sensor. Later LH 2.x used a Hall-Effect (shutter wheel on the crank), and it's possible early T5.2 used Hall-Effect, but T5.5 - the only thing worth swapping to - is VR. There *is* a Hall-Effect sensor used for road speed (VSS), but the crank position is set via VR.
From the t5suite manual:
Crankshaft position sensor (LM1815)
The crankshaft sensor signal needs to be amplified before the microcontroller can interpret it. This amplification is done by the LM1815. It is probably used in adaptive mode (mode 1). In this setup the signal from the VR pickup sensor for the crankshaft position is (filtered) supplied to pin 3 (Vin). The nice square wave signal is picked up from pin 12 reference pulse out) and supplied to the microcontroller for timing and counting
