737-8XX APU

Greetings to all!

Just a quick question, Boeing 737-8xx 's APU (Garret or Sundtrand) panel, you have only the EGT monitoring. IS there any way to check the RPM? as to know the APU load?.

when you start the engines by using the APU bleed, the duct pressure shows 19psi (because the APU is idle!) but when the ground switch moves to GRD position of the engine, the Duct pressure rise to about 35-40psi as the APU is now loaded. So I was wondering is there any way to check the RPM of the APU while starting the engine?. What would be the starting sequence for APU bleed induced engine start?

Thanks

(for some this may sounds like kindergarten! if so pls ignore! )
