Custom Nissan ECU Application with ScannerPro !Help!

dfddfd2 · Post by **dfddfd2** » Wed May 21, 2008 6:12 am

I have a simple custom application running on a Nissan ECU and have tried to get ScannerPro working with it to no avail. When the ECU receives 'L' followed by a CR (0x4C 0x0D) it returns the 16bit (2 byte) RPM. The 'L' and CR are echoed before the RPM is sent.

ScannerPro output shows:
2.285: Command sent. Reply not processed.
2.288: Command sent. Reply not processed.

Here's my ADX file:

Any help is greatly appreciated!

Hi, I own a nissan sr20 and I would like to ask you if you could send me your ADX file cause I don't know how to configure it. I would appreciate it if you could help me.

I'm developing custom firmware for the ECU called TunerCode along with XDF and ADX files for TunerPro V5. If you're not already a member, you might want to join http://www.sr20forum.com/. Details will be available there in the http://www.sr20forum.com/calumsult/ forum soon. My sn there is dfddfd2.

Thanks,
Dave
