(v2.0) This App is now free.

(v1.08) Just a bit of UI polishing.

(v1.07) Well, it was said that the Cerbera, from 0-100mph, will out drag a Tornado Jet.
A Tornado Jet has a Head Up Display, so I thought it fitting that a Cerbera should have one too :)

Connection Details:

For the MBE ECU used in all AJP8 and AJP6 cars, TVR used two types of connection terminal.
• A female 9-Pin D-Sub RS-232 port on the ECU motherboard.
• Or an external female three way cable plug connector.

Earlier cars had the 9-pin D-Sub connection, and on later cars access to the ECU was made available via the three way cable plug.
To get the diagnostic software to connect to the ECU in your car you need to determine which of these two types of connection you have.

If you have the earlier 9-pin D-Sub connection then all you need is a:
• USB Host enabled Android device
• USB OTG Cable
• USB to Serial Cable

If you have the later three way connection you will ALSO need:
• An extra cable that has a female 9-pin D-Sub RS-232 connection on one end and a male three way cable plug connector.



Detailed Cable Guide:

• USB OTG Cable
I have successfully used these OTG cables with a Samsung Galaxy S3 and S5.
