Description
LSU 4.9 Sensor When tuning an engine using wideband AFR feedback control on an inertia dyno, deadtime affects the data you are looking at because it is reported in a different operating location than when it actually occurred. This means with long deadtimes, whatever changes you make to the base fueling will likely be in the wrong location. This can be particularly dangerous to high compression and high-boost forced induction vehicles, and EFI systems that use feedback control to auto tune.Reducing deadtime improves wideband feedback control, and can provide a safer, more powerful and accurate tune. AEM’s Wideband Controllers with X-Series digital technology can reduce deadtime and improve the performance of your vehicle through more accurate AFR tuning.
- X-Series Inline Wideband UEGO AFR Controller were fastest responding wideband air/fuel ratio controllers in an independent test vs. 17 competitors wideband AFR controllers
- Patented X-Digital technology (Patent 9,575,030)
- Includes Bosch 4.9LSU wideband UEGO sensor
- Factory calibrated resistor does not require free-air calibration, but technology allows for free-air calibration as sensor ages if user desires
- Compatible with vehicle/system voltages up to 16V
- 0-5V & RS232 output for data logging and feedback control, AEMnet (CANbus) for data logging and daisy-chaining multiple controllers up to 16 cylinders
- Weather-resistant, low profile design
