ECU/EOBD Simulator

KWP2000 Simulator

KWP2000 Simulator

Today I decided to look for a proper OBD II/EOBD simulator. This would save so much hassle as I wouldn’t have to be going out to the car every second checking if a change made works. Further more, currently my SBC is plugged into a mains so it awkward getting it powered up in the car.

I decided to go with the KWP2000 protocol simulator as this is the same one in my car. I guess I really should pick another one and get tested on both types but I can simply just plug into another car later on anyways.

The one I went with cost 99 euro and is on this page: http://www.ozenelektronik.com/?s=products2&group=eobd-obdii-ecu-simulators

This project is costing me a fortune! – Hopefully everything will pay off in the end now.

Scantool.net and their ElmScan 5

ElmScan5 Serial Version

ElmScan5 Serial Version

Today I received a genuine ELM327 Tool (ElmScan 5 ) from Scantool.net. These guys kindly offered me a free one worth 130 dollars since I was doing it for my final year project. Unfortunetely they sent me the USB version and I wanted the RS232 serial version so I may send this back. Technically though it should work away by using /dev/ttyUSB0 since the kernel is 2.6 and supports the FT232RL chip that is in the USB version that gives a virtual USB com port.

Anyways I think I’ll be better off going with all serial at this stage just incase it causes problems down the line so might send it back to them. Thanks Vitaliy!

Scantools are located here: http://www.scantool.net/scan-tools/. It is important to buy the ELM327 Scantools from here as ones on ebay and other places are generally fake replicas and do not work fully. Poor quality etc. I know myself since I bought one for 50 euro and it gives up randomly.
