Hello. I am hoping someone on this forum can help me. I constructed a dyno control system using OEM modules and harness from an SVL90-2 to run the V3800 on an engine dyno. I have the Kubota Denso Engine ECU, Main ECU, Meter and APPS.
I have the engine running on my stand but cannot increase throttle off idle. I have removed the DPF from the ECU using KTAG and I do not have any error codes in the Meter or DTCs in the Engine ECU. All the cab switches, inputs and hydraulic solenoids have been simulated. I can read codes and clear them with my version of Diagmaster but I cannot see any live data PIDs. I went through Service Mode in the Meter (no-01) and checked the settings, inputs, etc. My throttle has been calibrated correctly using Service Mode in the Meter (it completed). The only thing that is strange is that I cannot release the parking brake. The switch reads on and off in the Meter's service mode, but when I push it off with the engine running, the parking brake stays on. With my simulators I can unlock the hydraulic system when the engine is running, which is odd.
Is there something else I am missing? What in the skidtsteer is required to increase throttle? Sitting in the seat, starting it up, arm bars up or down? Then what? I am not familiar with the equipment itself, just trying to dyno test the engine.
Thank you for any help!
