Hondata

So I have been lurking a bit and have found some bits of information on this, but still having a difficult time wrapping my head around it.

I have 3 AEM Gauges.

• 30-4110 Wideband

• 30-0306 Boost Gauge

• 30-0301 Oil Pressure Gauge

All values work fine on the AEM gauges themselves.

Wideband works fine as Analog Input 0. The Boost and Oil Pressure gauges do not.

The Boost Gauge (30-0306) and Oil Pressure Gauge (30-0301) has 2 wires from the gauge I believe are what I need to connect per their documents.

• https://documents.aemelectronics.com/te ... 0-0306.pdf

• https://documents.aemelectronics.com/te ... 0-0301.pdf

My understanding is that the White (0-5V Analog Out) goes to my Analog Input (AN1 for Boost, AN2 for Oil Pressure) and the Brown go to the Sensor Ground on the Analog pigtail for the Hondata.

As far as Analog Input configuration, they would look as follows:

Analog 1 (Boost 30-0306)
Conversion: Custom
Type: Pressure
Unit: bar

Voltage:
0.5v -> 0 bar / 0 psia
4.5v -> 3.4 bar / 50 psia

----

Analog 2 (Oil Pressure 30-0301)
Conversion: Custom
Type: Pressure
Unit: bar

Voltage:
0.5v -> 0 bar / 0 psia
4.5v -> 6.8 bar / 100 psia

So my questions are as follows:
1. Is the wiring direct since it comes from the gauge?
2. Do I still have to use bar for custom or can I use PSI?
3. When I had this setup in KManager with bar, the values at engine off/key on, showed 0 on both gauges, but live view showed non-zero values in the Live View when adding those sensors.

Any help would be appreciated.

How exactly do you have these wired?

Post the calibration and a datalog showing the issues.

For now, this is the wiring.

My Configuration was listed in my initial post, but I will update with further screenshots of what I am seeing when I am home. When units were in Bar and PSI, the Hondata view and the Gauges did not match. (Boost and Oil Pressure 0 on Gauges, Hondata non-zero for one or both) When running the numbers were in the thousands.

Okay, I might of just been looking at it too long over the weekend. Oil is working, Wideband is working, Boost is showing ~14.4 but gauge shows zero, so I am guessing that is 1bar of pressure that you subtract from boost basically. So as long as that wiring is right, I think were good to go. I think I originally tried setting up PSIA scaling on the custom setup (to use PSI for display/logging) but once it was setup to use bar on the Analog Inputs, things started working normally.

Just a few too many variables overwhelmed me this last weekend.

The thing that confuses me, is why does the input have to be in bar, if the view is going to output PSI? Why can't I just setup it up using the psia units and scale according to AEM? Or input in bar and display in bar?

bumping your old thread but what was the verdict? can these be in PSI under custom value or not?
