Hello, we are experiencing issues calibrating the ignition cut during gear shifting on our Motec M142 ECU. We have a load cell in the link between the gear lever and the gearbox (attached photo of M1 calibration). The problem is that the data does not consistently indicate when the ignition cutoff is activated, resulting in variable force readings. This makes it difficult to determine the correct timing for the gear shift.

We are recording the gear, gear shift, shift lever force, and ignition cut status channels at 20 Hz. Would it be possible to add the ignition and gear position sensor channels to the existing channels at the same 20 Hz frequency? What additional channels and sampling frequency would be recommended to analyze and diagnose the issue of inconsistent ignition cut activation during gear shifting?

We're probably doing something wrong.

Other questions:

What effect does the estimated gear shift have with a gear sensor installed? We have all the gear ratio data loaded.

What effect would setting different gear tolerance values ​​have on this problem? What would be the most logical values ​​to start with?

Thanks, best regards!!

Hi,

When you talk about adding channels, are you meaning in the Time Graph, or the Logging?

We really need to see logging of the issue, rather than screen shots.

Thank you very much for the response.

Regarding the channels, I meant editing the datalog, adding channels if they're not listed, or grouping the necessary channels on the same frequency.

Attached the data files.

Hi,

The first thing that you should do is upgrade to the latest version of the GPR-DI Firmware, you are running a very old version that has had a lot of updates done to it since release, including in the Gear Shift functionality.

Hi

Thank you very much for your response.
I understand. I've always wanted to do it, but I've been very wary and afraid of updating the firmware. What precautions should I take? Is it possible I need to configure other parameters. Is there a tutorial,pdf,etc? Do I need another license?

Thanks,Best regards!

The advantage with the M1 is that you always have a copy of the current Package available, so if you need, you can just revert back to that.

According to your licence information, you should have the current licence for the latest release of GPR-DI on your M1.

I would use the Compare tool to do the migration, starting with opening the new package first and then adding the current Package into compare, then use the Migrate All button at the bottom of the window. The Migrate All runs a number of processes in the background to assist in the migration process such as purging the allocated resources and calibrations from the Package that you are migrating to and remapping changes to naming conventions in the Package.

Once this has run, a Migration results window will pop up giving you information on what worked and what didn't, this can be saved for later reference. You will get a large number of warning with this migration as functions have been added to the Package, work through these in a methodical way. You can also manually move data from the old Package into the new, either by clicking the blue arrows on aligned components, or by dragging and dropping.

Hi Stephen,

Thank you very much for your response.
I'm working on migrating the firmware, but in the latest versions, there's a warning that the license must be updated. Is this correct? Is there an additional cost?

Thanks,regards!

Hi,

Send the serial number through to support @ motec.com.au and I'll sort it out for you.

Hi,

Thank you very much for the technical support.

Now let's get to work and migrate!!!

Best regards!
