My Torque Pro setup

[CigaR007]

I initially had a bluetooth elm327 obd2 adapter but quickly realized that such a setup was providing limited performance in terms of PID read speed. The BT device was only capable of displaying and refreshing 5 sensors per second and would often disconnect from the ECU. With modern canbus networks, cars can now provide very fast communication speeds.

Below is the layout in my car



I opted for a wired obd2 connection as to ensure stability and fast communication. The obd2 adapter connects to the android tablet via a OTG USB-C cable. Below is the performance of said device.



With the wired adapter, Torque app can read close to 200 PIDs per second. The previous BT adapter was reading at 40 PIDs per second. This allows to display 10+ live sensors on the same page in Torque app.

PROS


Takes advantage of modern canbus network speeds
Very stable connection
Hackproof versus BT devices
Highly customizable setup
Logging data and graphing sensors


CONS

Connect the device prior to departure, each time
Cable from obd2 plug to tablet
Fuel consumption readings slightly off. Requires more calibration.

I seriously considered the Scangauge III, but I could not justify paying $300+ for a device that cannot log data. I will say though, LinearLogic offers reliable products and excellent customer support. My scangauge II is 11 years old and still going strong, but it was time for an upgrade.

Cheers.

Decided to log multiple sensors on today's trip. Below is a scatter chart representing the fuel consumption vs the ignition timing. From what I have read, a higher ignition timing usually translates into better fuel economy. As per the chart, that assumption seems to hold true.

Notice the two parallel oblique bands and the somewhat dead zone between them. What seems to be going on there ?

My hypothesis is that the lower band was driving at lower speeds (±45 mph) for a brief period of time. Most of the trip was averaging 60 mph.

A-B-A test at different constant speeds?

That would be the ideal scenario. Problem is finding a flat and long section of road...

I inquired with a local testing ground facility (oval circuit) and they do not grant access to the general public; only companies and universities. Shame, as I would have liked to test my kammtail setup once completed...oh well.

Below are a few other charts :

I'm impressed with your car's advanced CANbus network and the impressive communication speeds it offers. The ability to access and display data from multiple sensors simultaneously is truly remarkable. I can only imagine the possibilities this opens up for real-time vehicle monitoring and diagnostics.
