  1. In G4X knock setup, in Frequency Channel, if using the nissan factory knock sensor (not Bosch aftermarket sensor), is it still correct to chose 6kHz Narrow Band Filter ? Thanks !
  2. How can I use existing defi oil temp and oil pressure sensor signal feed into G4X as an analogue V input without affecting each other operation ?
  3. You are right !!!! Problem solved, found out it is an anti-thief thing hack into the ECCS relay, the guys who install the anti-thief, if it is unarmed, the ECCS relay will normally supply +12v power to the ecu, if it is armed, it cuts the power by an extra relay, and "short" the +ve side into the ground , thus the fuse will blown everytime if the key is on (if the anti-thief is armed), and the anti-thief itself will auto turn into "armed status" everytime connecting the battery.
  4. I'm the mechanic of this S15, car battery had been disconnected for 3 weeks , for engine bay hardware installation and brake upgrade. When installation complete, reconnect the battery trying to start the engine, there is no spark and injector firing. Try connect PC Link via USB cable, it shows warning message "Error: ECU is running in Boot Mode and cannot connect, Please run the firmware update program again." Tried everything included disconnect battery again , load PC Link software again, unplug and plug USB cable, try another USB port, still the same. Following another post disconnect engine harness and apply 12V to ECU board, disable auto connect function in PC Link, run Firmware update again, In the first time using external 12V power, pop up window shows "ECU running in trap mode.....", ignore the message and do the firmware update, a pop up window shows ""Upgrading from 0.0.0 to 6.20.33.......", after the green bar on the bottom ends, another pop up window from the firmware updater shows "PROGRAMMING COMPLETE. ECU is ready to run." Click OK to close that pop up window, disconnect the external power, remove the jumper wire, close the ECU cover, conect engine harness, turn key and reload the PC Link, unplug and replug the USB cable, PC Link shows the same message "Error: ECU is running in Boot Mode and cannot connect, Please run the firmware update program again." Repeat the external power firmware update method again, result is the same. Please help ! 2x Blue LED is on ! Did not try jump wire supplying 12v to mainboard when engine harness is connected.
