each engine application. These signals will be fed back to the teams via CAN.

All Prototype cars must run:

 Cockpit temperature
 Pitot tube
 Laser Ride Height sensors (if used)

In addition, DPi cars must run:

 Engine Sensors

o Intercooler Upstream temperature(s) (Turbo only)
o Plenum pressure(s) (NA only)
o Plenum temperature(s) (NA only)
o Inlet Port pressure(s) (NA only)
o Boost pressure(s) (Turbo only)
o Inlet Port temperature(s)
o Restrictor Throat pressure(s) (NA only)
o Lambda(s)
o Fuel flow meter
o Engine speed sensor

Sensors must be installed in an IMSA approved location as identified in
Scrutineering System homologation documentation.
