Com Port Selection in TP v5

RhinoPower · Post by **RhinoPower** » Fri Jul 29, 2011 6:41 am

I have a USB-serial interface for communicating with a Suzuki OBD1 ECU. I've spent several hours writing an adx definition file but I think I've now run out of brain power. I can't find an option that allows me to select the COM Port, under Tools and preferences I can only find the option of selecting 'TunerPro Data Acquisition I/O Interface' 'Standard Serial' and {COM1}
I'm sure it should work because one of muy customers has run one of my interfaces on a Vitara with TP5 already.
TIA

OK, I have the comms working although it doesn't seem very reliable - I'm getting a lot of data errors. The Suzuki specification calls for 100ms minimum period between data requests, I am sending a data request and then waiting for reception and then pausing 90ms, I have tried extending the pause to 200ms but I still get errors, the interface is well proven and doesn't usually return any errors at all.

The adx file is here if anyone wants to look at it: http://www.rhinopower.org/TunerPro/1112.adx

There is a description of the Suzuki protocol here:

I have two parameters, battery voltage and baro that only very occassionally show the correct data, at all other times they show zero.

I will take a look at the protocol. If you don't mind, email me your definition and I'll take a closer look.
