A) Point Ai is 20
B) Point Ae is 40
C) Number of teeth
D) Missing teeth
E) Cuts per turn
8) A short touch on the + and - keys alters the intake phase
(CMPi) of all points on a tooth, which is equivalent to moving
the timing belt on the intake cam.
9) A long touch (more than 1 second) on the + and - keys alters
the exhaust phase (CMPe) of all points on a tooth, which is
equivalent to moving the timing belt on the exhaust cam.
NOTE 1: It is very important to know that in most cases the
ECU will start to emit gasoline and spark, so make sure they are
not connected.
NOTE 2: The motor will not start, because the pulses are not
related to the actual mechanical position of the motor.
Generation of Analog Voltage GEN AN)
The HMP1 can generate analog voltages to simulate analog sensors.
The test can be with a manually generated voltage or use one of the 5
curves built into the HMP1.
The voltage comes out through the TPS2
pin and is injected by disconnecting the
true sensor.
The purpose of these tests is to inject the
voltage and monitor the ECU's response
and reading of the input voltage / signal.
This verifies both the wiring and the ability
