Whats needed:
- Tactrix cable - http://www.tactrix.com/
- Laptop
- Open Source logging Software - http://openecu.org/i...title=Downloads
- 5min - 1 hour depending on what you want to do
After installing your chosen software, read the instructions. I recommend ecuexplorer(free), after reading the instructions simply plug in your tactrix cable to the OBDII port under the fuse box inside the cabin on the drivers side and plug that into your laptop. Start the car and the start ECUExplorer. you should now be connected in real time to your ecu and will be able to select what parameters you wish to log on the right hand side. On the left hand side will be your ECU information wich is extremely usefull for tuning as you will need to create a def file but thats another thread.
Setup the program to start logging to file when you push the defogger switch to make it easy for you. Its also a good idea to find out where the log files will be saved to.
After all this has been done simply drive the car and when you wish to log press the rear deffoger switch and it will automatically start writing to file, when you are finished press the deffoger switch again and it will stop.
Easy as pie. This information will show you how your car reacts to certain situations... what load its running, how much fuel its pushing through the injectors, the AFR at any given point etc. This is an extremely usefull tool for tuning purposes.
For retrieving error codes you will need to do the following.
- Connect the green test plugs under the dash on the drivers side together
- Start the car
- connect the laptop and start ECUExplorer
- Choose Trouble code reader on the left hand side and this will show the current trouble codes (if any) on the right hand side. It also shows historic trouble codes.
I hope this makes sense to everyone, any questions just ask and i will reply ASAP
