Config L120 & SLM

[ToddG]

Hi all, I hope you are doing well!

I installed a SLM to my L-120 and it works, but I am having trouble configuring the L-120 to do a specific thing with the SLM.

My MoTeC system includes:
L-120 with 120Mb Logging, bought new from authorized dealer that is no longer in business. This was installed and configured (MX-5 CAN-Bus & VBox CAN-bus) by myself with very minor help from the dealer.

i2 Standard software. I have no need for i2 Pro in my performance engineering of drivers.

SLM bought new from an authorized dealer.

What I want the SLM to do is display a bar graph representation of a very simple math channel that I made in i2 Standard:

'Steered Angle' [rad]-'G Force Lat' [G] This i2 Standard bar graph has manual scaling of min 0.50 & max 1.00.

The reason I want the driver to see the bar graph in real time is it shows excessive steering input when the lateral acceleration is no longer also increasing. In effect scrubbing the front tires.

I am dreading the feeling that someone is going to tell me that I am required to buy the "Pro Analysis" upgrade for the L-120; when I had absolutely no need for i2 Pro.

Thank you for any help!

Can you create your math channel in the L120 and display it as a number? That is your first step.

I can in i2 Standard. But I can't in C125 Dash Manager. There is nowhere to make a math channel. "Math" isn't even in the help index.

Correct, there is no Maths function available in the L12/C12 series of loggers.

You have 2 options for this:

Use a 3D table.
This will require some manual data entry, but you could set one axis up as steered angle (rad) and the other as lateral G and populate the table with the required numbers.

The output value from this table could then be used for user conditions which will be the conditions for each of the shift lights.

This will achieve the result you are looking for.

Change to an L180 logger
To generate Maths channels, you require an L180 logger with the advanced functions enabled.

This is a more costly approach and by the sounds of it excessive for your intended purpose.

Thank you for the confirmation of no maths function. I came to the same conclusion of using a 3D table.

I absolutely adore MoTeC i2 software. It is the perfect tool to apply the writings of Jorge Segers. The software and CAN-bus sampling rate is the only reason I use anything MoTeC.

BUT! It is absolutely insulting to the end user that MoTeC views only "Professional" level products are capable of elementary math! e.g. No square root function in i2 Standard, and no math functions in the MoTeC "Race" hardware!

The common thought that doing very high level professional performance engineering requires over $10,000 in hardware needs to stop.

Stepping off my soap box.

Thank you for the help, and have a great day!
