  1. My wiring harness does have a wire connecting to that pin on the stock ecu, and also has a conventional fuel pump relay. It should be very easy to turn this pump on. I will try your suggestions and let you know how I go. Thanks for your help
  2. Hi Adam, wish I had thought of grounding the wire out. The car is my daily so its back together running on stock ecu, will test your suggestion as soon I have a chance. Regarding the BEAN, could you elaborate? As far as the AltezzaLink documentation says, the BEAN is for A/C, some temperatures, battery voltage, etc. Fuel pump is not mentioned. Both the Altezza and JZX110 each have a single ecu pin which is for fuel pump relay, so I was expecting it to work similarly in both cars. Admittedly this is my first time delving into programmable ecus, so hopefully I'm not way off. Thanks for your help EDIT: I've done a bit more research. Is it possible the expansion connector AUX8 is not able to operate a fuel pump? As seen here:
  3. Hi guys, hoping for some help. I selected the AltezzaLink ecu for my JZX110 with 1JZ vvti due to this ecu supporting the e-throttle and toyota multiplex system. I have made a patch harness which converts the JZX110 pinout to the altezza pinout. Injectors, ignition and throttle are working (tested), but fuel pump relay output (on expansion connector AUX8) is not turning fuel pump on. The fuel pump status always remains off. When choosing the TEST ON or TEST PWM options, the status does show as on but still no fuel pump. I've double checked my wiring. Can anyone suggest a solution or reason for this issue? Thanks, Mitch
  4. Hi Blackwing, Are you using the HKS adaptor harness? From my understanding, the Kurofune doesn't support DBW, so the stock JZX110 ecu must remain to control factory DBW. Alternatively, there are kits which manualise the throttle on JZX110s, essentially making the E-throttle redundant. Personally, my planned ECU choice for my JZX110 is an Altezza link. Connecting the Altezza link to the JZX110 harness is either by re-pinning the JZX110 ecu plugs, or making an adaptor harness. I'm in the process of making an adaptor harness. The stock DBW should remain functional as the Altezza link supports it.
