There is another option, "BLM Params - Key On, BLM Table Initialise Temp Threshold". Set this to say choose when you want the BLM table reset, if the CTS is less than what you set then at key on it resets the BLM table for you - maybe 40deg if you want it only when the car has sat for a bit, or 151deg for every key on. Saves having to remember to send the reset command after making changes. When your done, return it to the default -40deg and it will keep the BLM contents at key on.

Ok I'll have a go at this option too. Thanks vl400.
