AFR Gauge question
 

Looking to install Innovate DLG-1 Dual AFR gauge in dash. Anybody done this? Is it of any value to you? Will it last?
Any experience welcome. Thank you.

I don't have that gauge installed but the MTX-L installed. I've been running it for 6 years now.

Keep it dry. Water and O2 sensors don't get along well at all.

Makes tuning a breeze.

This.....in fact now I can't imagine operating without it. It's a great trouble shooting tool on the fly should an issue arise. It offers the ability to discern between electrical and fuel problems. For example, you hear the motor stumble and quit and the AFR rolls to 23+, you know you had a fuel issue (I had this happen when an internal diaphragm failed on a VST pump). If AFR was steady and the motor quits or stumbles it points towards electrical.

Lean reading on an 02 can be a misfire also.

I like them as a tuning tool, but really don't have a need for them full time. Fuel pressure dropping will show you the same problem a lean air fuel reading will. It's all just data, it's up to you to interpret it.

That is why I am considering. Seems like it could be a lifesaver as far as fuel tuning under various loads. Nobody seems to mention using these as dash tuning tools. How is the accuracy of these gauges and how sensitive while underway?
Thanks for the responses.

Answer to your questions in order 1 Yes, 2 Yes, 3 Yes, depending on your engine CONFIGURATION it can be a very useful on the fly engine monitoring tool, just as all other monitoring gauges, for those who bother to look at them! LOL. I use the DGL-1 dual. Note as others have cautioned, make sure the sensor is placed away from any water reversion.

Disclaimer: Always take the time to read your plugs!! more so if the engine has not been run on a dyno first!!

The problem is watching fuel pressure drop will not tell you HOW lean it got. Did it go from 12.5 t0 13.0? That wouldn't concern me too much. If it went from 12.3 to 15.0 under load now that would be an issue. Wideband will tell you that. Fuel pressure will not.
