Re: Crazy AFR fluctuations
I ended up bringing it in to my mechanic. He said it was a grounding issue aswell. It's not as bad now but when warming the car up in reads 10 on the gauge. Can you provide a picture of the ground you speak of?Hondata wrote:It needs to be grounded to the same place as the ECU, which on the S2000 is on the back of the cylinder under the cowl. Otherwise you get a large ground loop and possible voltage offsets. Almost all widebands are not well designed as they shunt all the heater current down the same ground as the analog output, but adding in a ground loop does not help.
