Features

  • The X-Series wideband UEGO AFR sensor controller gauge (PN 30-0300) features a modern, visually striking faceplate and new seven-segment, center display that is 87% larger than the 30-4110 AEM
  • The gauge includes a 0-5v and RS232 Serial Port output for feedback control and data logging, and an AEMnet (CANbus) output for data logging
  • X-Digital wideband technology gives these controllers the ability to read and report values that other controllers do not, which can deliver more optimized engine tuning and a safer overall operating condition
  • Faster response time improves wideband feedback control, and can provide a safer, more powerful and accurate tune
  • When tuning an engine using wideband AFR feedback control on an inertia dyno, dead time affects the data you are looking at because it is reported in a different operating location than when it actually occurred

Description

AEM's X-Series wideband UEGO Air/Fuel ratio sensor controller gauges are built upon unique, patent-pending X-Digital technology that makes them the fastest responding wideband air/fuel ratio controllers in independent testing against 17 other wideband UEGO air/fuel controllers.

Very accurate, and is the best thing I have bought for a carbureted engine. Very easy to read, and has been going strong for over a year now. No complaints.

Once integrated with the 95 mustang GT I confirmed that the car was running lean. Chasing the perfect stoich now. Trying to keep my eyes on the road instead of the gauge at WOT is difficult. I find myself wanting to watch the gauge a lot. Drill 7/8" hole for bung and used dremell to cut two curves into the recessed side of the exhaust bung for better fitment. MAKE SURE THE WELD HAS GOOD PENETRATION and doesn't have any pinhole leaks or you WILL see false lean conditions. It can easily be used on many different vehicles or installed permanently. ... show more
