Use VTP as AC Switch input

[Michaelek9]

I need help on my PRB Hondata ecu with code 10555 I wired the the VTP (B9)as AC input but I cannot get output from ACC(E18). Through this issue i cannot run my AC unit.

When the engine is running the sensor window shown the VTP is on where in the Vtec oil pressure switch is already disabled from Vtec window.( Hondata Parameters).

I believe you have a PRC ECU and it does not have the circuitry for VTP.

yeah you are right the ecu is 37820-PRC-013.

Is there any solution for that?

Im facing problem on the software everytime i change the unit from kpa to mbar it doesnt change the unit and the value, same as the unit to Fahrenheit to celcius.

There is no solution for that

Can you please be much more specific in exactly what you are referring to with a software problem.

Okey on the display mode i have changed the unit for the Vacumm (from Kpa to mbar) and the Temperature (from Fahrenheit to celcius) from the Settings, it doesnt change the unit and value on the display.

Options menu, Settings, Units Tab. Change Fahrenheit to celcius.

Go to the sensor list and change the units there, then go to Options, Settings and mke sure you change the settings there as well.

It doesnt work, no change on the value :(

Please post your calibration, a datalog and your display file so that I can see what you are referring to.

Is the VTP as AC Switch input feature working with ECU 37820-PRD-013 ?

[Spunkster]

That ECU does not have that input.
