Apparently I have to ground my wideband to the same location as the ECU. Which happens to be the back of the cylinder head.

Does somebody have an idea where this is? Picture? details?

Thanks in advance!

I dont see why you wouldn't tie it to chassis ground.

a ground is a ground is a ground IMO

its on the back of the head between it and the firewall. make sure you tighten it back down well. i had that bolt start to back out and it caused it to intermentantly have a 3000 rpm rev limit. i found it when i pressed on the wires with the car running and it shut off....

I don't know why it's so important either. But my tuner and hondata support both say it's important to ground it there.

I have it grounded elsewhere and my wideband output to the flashpro is not reading the same as the gauge

Is it easy to access from the top?

Anywhere on the cylinder head will be fine.
