rs tunner help

[inpassing]

just bought the rs tunner and going to use it today. it says in the instructions that i have to make sure car is on 'full ignition' and not to use it in freezing temps. what exactly is full ignition and how cold does it need to be outside for it not to be safe to do this?

 

[MartinR]

Ignition on with all lights illuminated on the dash. Above 5 degrees i would say is ample.

Yes it's above 5 degrees. I tried it once though, in the cold, and gave me errors about not being able to read the ecu.
So my advice: get warm somewhere, or don't do it until it's warm enough outside.

connect to battery charger, mine worked perfectly when i did but when i tried to read cal / ecu to start with, with no charger it threw up errors.

Yeah Henk told me if there's errors it probably temperature or battery voltage or both.
