# Tips and Tricks

## Power cycle ECU

Should be done after any change that is not to a tuning table

## Always have a main relay

And wire that relay correctly

## Why do I have XYZ error?

Check error code and compare to this list (grab list out of firmware)

Make sure these are always numerically ascending (i.e. 1, 2 ,3 not 1, 1, 3, or 1, 3, 2.)
