### 1/5 — Much modification required.

*2018-10-14*

As a result of the unit being a waste of time I was able to make some modification to the program and use the components already in place as a result I am now able to access a wealth of further information and make changes to the operation of the engine. I have piggy backed this unit in line with the gps system. Now I have a useful functioning system. I have not been able to carry the diagnosis alongside a separate tool. Do not leave the unit connected during driving this may result in an intermittent loss of power.
