I purchased an Autometer A/F ratio gauge, and I'm hoping to use it to help tune my car with my tuner. Who else runs these? Also, I know there are "open-loop" or "WOT" gauges that have been modified for use at WOT. I've read the directions on mine, and it says that when the computer goes into open-loop mode that the cars EEC will richen the mixture to a point where the gauge will just read "rich." So I'm assuming these modified one's lower the range of it's sampling or something so you can tune your WOT settings. I was wondering if anyone was using one of these also?

The problem is I read about this on a site that performed the modifications, but don't remember what it was.

I'm hooking up my non-modified one tomorrow hopefully, and plan to mess around with my EEC.

Plus it will be a good thing to have when running my NOS. I'm installing it in a dash pod with a fuel pressure gauge.

Do you have it mounted now? is it working?

Stock sensors do Not react fast enough for tuning @ wide open throttle with a little A/F gauge like the one from Summit.
they work for letting you see where the mixture is at idle and part throttle, and that can be helpful. but for WOT, all bets are off. they just don't cut it. They also come in handy for diagnosing a lazy sensor.
