TACH Signals for BOTH Motors

Toyota doesn't publish the parameter definitions (address, data type, unit) ... historically, the auto industry has bent over backward to keep those secret, always arguing that it's not just to stifle competition for their scan tools, but that they'd be giving away Valuable Trade Secrets. Which is rubbish, because you easily find Toyota publications that give you the names and meanings of all the parameters you could look at. Surely if it's a Valuable Trade Secret that (say) you compute equivalent torque from a brake request, you've already given that away when other car makers can see that in your listing of parameter names and descriptions! Just keeping secret the fact that it happens to be bits 0 to 15 of parameter c8 does nothing to protect your trade secret, but is an infuriating roadblock to everybody with a legitimate desire to monitor stuff in their cars.

Sooo ... people figure out the addresses anyway. Look around this forum for posts about using the ScanGauge, the Android Torque app, etc. Five years ago I made a start at a single-common-format clearinghouse on SourceForge, but I don't think anybody's contributed any data except for Gen 1 yet, and I've been distracted for a while from evangelizing for it.

I am assuming you mean the two MG's. The rpm info is available with an OBD reader.

 

I'm using Torque Pro on my Note3 with a Bluetooth ODBII reader.

One of my gauges is a tachometer.

When the gas engine is running a see a reading... when on the electric side I see nothing.

So, I have to see if there is a tachometer for the electric side.

Sorry, that's all I have

I've only had my v3 for a few weeks.

The RPM's are available using the X-Gauge capacity of a ScanGauge. I am not familiar with your reader. If you can customize the OBD gauges, you can probably make it work.

 

If you know engine speed and the car speed, you can compute both motor speeds using the gear ratios and simple algebra.

 

I think you have to use scangauge with a newer firmware to show both MG1 and MG2's RPM. Older version can only show 1 or the other. You do have to program the X-Gauge to show the MG1 MG2 RPMs.
