External AD and TEMP inputs

[mr.prick]

Check the factor and offset used to calibrate the A/D voltages.
You can check using EFILive_Hapi on the "F5: Calibrate A/D" page. Click on [Get Factor/Offset] to see what they are set to.
If you click [Display data] you will see the raw A/D counts and the calibrated voltage.

Don't click [Initialize] or [Calibrate] unless you really mean to supply the appropriate voltages and actually calibrate the sensors.

No factor offsets are shown and no voltage for any AD now.
Also recording with scan.exe AD1 and AD2 shows no voltage.
In the self tests of V2 I see AD counts for AD2 now but external sensor
data shows nothing for AD1 and AD2.
Basically AD2 works but now voltage is not being displayed for
any of the ADs through V2 directly or passthru.

Ahh, sorry my bad. I only tested using BBL and displaying the AD values on FlashScan's screen. That's the only condition under which they work. I've removed the debug that was preventing all other views of the AD voltages from being processed.

Try this version.

AD2 is officially fixed!

I am using firmware 2.06.10 May 25.

F4 Options -> F4 Self Tests -> F3 External Sensors -> F1 Display Sensors:
I see AD1-4 pegged at 0.05V regardless of input voltage (1 or 2 AA batteries, measured with DMM at AD+/- inputs).
See image below.

F4 Options -> F4 Self Tests -> F4 Self Tests:
I see the second bottom row of 4 numbers is 1 1 1 1 where occasionally the 1's become 0's for a moment.
See image below.

Connecting to car's OBD-II port, logging in BBL, I see the following voltages (DMM said external voltage at orange connectors was 1.362V):
AD1: 1.39V
AD2: 1.42V
AD3: 1.39V
AD4: 1.39V

i.e. at the moment you can only view the AD voltages by doing BBL logging.


BTW: the attached images of Display Sensors and Self Tests is what HAPI captured and saved to file... the left 90% of the image is missing.

Yes,
HAPI and the V2 control panel are not working if you want to calibrate them.
They show no AD or voltage.
I have given up on calibrating mine to be perfect, they float too much.

[joecar]

I also tried calibrating using the V2 calibration display but I couldn't get that to work.

[mr.prick]

Did you try with the V2 by itself?
Also I have found that you must be connected to both PC and car to calibrate them
through V2 control panel and HAPI.

[joecar]

Yes, I was trying to cal with V2 itself... oh, connected to both car/PC, I see, will do... thanks.

Correct, for FlashScan to sample the AD inputs it requires 12V on the vehicle connector.

Is this still true? As I pressed the initialize and calibrate trying to work out why I was logging 1 value on fs but another on the gauge.
