Built for people who don't want another gauge in the dash but need accurate AFR for datalogging or closed-loop feedback with a standalone ECU.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eResponse time is the reason to pick this one.\u003c\/strong\u003e Patented X-Digital wideband technology reads and reports values other controllers don't, and the high-speed digital implementation means no loss of signal fidelity and full transient response — it catches the slightest fluctuations in AFR and outputs them at full value. In independent testing against 17 competitor wideband UEGO controllers, the X-Series recorded the fastest response time.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eThat matters for a specific reason: deadtime is the delay between when exhaust gas composition actually changes and when the sensor reports it. Less deadtime means better wideband feedback control, and a safer, more accurate tune.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eOutputs:\u003c\/strong\u003e 0-5V analog for any ECU or logger, RS232, and AEMnet CAN. Multiple controllers can be daisy-chained on AEMnet for up to 16 cylinders.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eSupports system voltage up to 16V. Works on EFI, carbureted, and dyno applications, and on gasoline, methanol, ethanol, diesel, propane, and CNG.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eFactory calibrated\u003c\/strong\u003e — the calibration resistor eliminates the need for free-air calibration out of the box, though you can run it as the sensor ages.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003eIncludes the controller and a Bosch LSU 4.9 sensor.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal\" dir=\"ltr\"\u003e\u003cstrong\u003eSensors are wear items.\u003c\/strong\u003e Leaded fuel, oil contamination, and thermal shock all shorten their life.
