How to turn a log into a tune

[KJD310]

Looking to get a fuel map I had on a log and put it back in as a tuneup.

Hi,

If your Lambda Table and Fuel Main Table have the same axis channels, then you can use the "Lambda Was" function (L on the Keyboard) and enter the actual Lambda value for that load point. The ECU will calculate the difference between the actual and aim lambda values and change the fuel value to suit.

I think you are asking a different question. You had the engine running on one configuration and downloaded the logged data. You then changed your Mx00 fuel table (assuming the engine isn't running as well now), and now you would like to return to the fuel table that was used when you logged the data?

If this is correct, then you may be able to use Tools->View Device Config... from I2 with the logged data file open. This will load the version of the config file saved with the logged data (Hopefully you had not changed the config since the log was made).

With this temporary file open in MoTeC ECU Manager, and the Fuel Table visible, you can Tools->Save Table... -- then reload it in your current configuration.

Alternately, you can just use File->Save As... to save the entire configuration, then later use Tools->Copy Table from another file to retrieve it into you current configuration.

Hope that is helpful...

Ya that’s exactly what I’m looking to do. I changed the base fuel pressure and didn’t get enough runs to tune it out so I was gonna drop the pressure back down and load that log if I could.
