Slow OBDII Port Readings
I'm looking for the fastest way to read information from the ECU into an Android app (Torque Pro/Dash Command/Whatever). Right now I have a cheapo $10 bluetooth unit that has severe lag.
I've found out that the 350z uses ISO9141-2 over the OBDII port and is likely the current bottleneck. Is there a way to use the Consult II protocol to transfer data? Would it be faster? I saw a video of some guys running a Consult I cable and it was instantaneous: |

I've downloaded a few apps and here are my findings. All apps are connected over bluetooth.
Car Diagnostic Pro Supports Consult II Protocol, Moderately Fast Car Gauge Lite/Pro Supports Consult II Protocol, Moderately Fast Car Scanner ELM OBD2 Supports Consult II Protocol, Moderately Fast NDSII Lite Supports Consult II Protocol, Moderately Fast Dashcommand No Consult II Support, Very Slow Over 9141 Torque Lite/Pro No Consult II Support, Very Slow Over 9141 EconTool for Nissan ELM327 Can't Connect |
Try going hardwired.

The only time I've seen good results are hardwire (or hardwire to bluetooth adapter) with Windows software or an aftermarket ECU. |
Maybe you have seen these already, but here are some ideas:
Wiring AIM products like the MXS via the OBD connector via CAN, lists the pinout functions: http://www.aim-sportline.com/downloa...II_103_eng.pdf Nissan Datascan Tool which uses consult iirc: https://home.exetel.com.au/nds/NDSII/index.php |
