ive been running my EMU CLassic for years with no problems, i am Using a AEM gauge/controller and have the Output going to the EMU i like to have a physical gauge to monitor AFR on the fly, i have the readings pretty close but i always noticed they arent as close as the can be between the Guage and ECU. Any tips on getting the both readings to macth as close as possible ? ive messed wit the Min/Max Voltages but perhaps there are some ways to get the readings to mirror each other alot closer or exact ?
PS. should i bias the AEM gauge or the EMU AFR readings when tuning ? i know the EMU will make its calculations off the EMU input, but if its slightly off or Slower the the Physical gauge should i Bias the Gauge when making changes ? hope this makes sense.
