Changes in Rev2
Resolution of Igr input problem
In Rev1, IG adapter was attached. In Rev2, main unit has been treated.
Changing Thr input resistance
The Thr input resistance has been greatly increased. This no longer affects the output value of the throttle position sensor.
In Rev 1, it was necessary to increase the input resistance with TP sensor amplifier, but it became unnecessary in Rev2.
Change signal of Thr connector
The red line of Thr connector changed from 5V power supply to Igr 5V pulse input.
Correspond to 5V pulse RPM signal
The 5V pulse RPM signal from ECU can be input as Igr signal. It is input to the red line of the Thr connector.
The negative electrode uses the black wire of the Igr connector.
|Signal||Positive electrode connection destination||Negative electrode|
|5V pulse||Thr external sensor cable red||IG cable black|
|12V or more pulse||Igr IG cable gray||IG cable black|
T1, T2 and T3 inputs support 50Hz. However, the app is currently uses 10Hz as usual.
This change can also be used in Rev1 by rewriting the firmware.
