The AEM 30-0334 gauge can do this. Comes with everything needed and is a simple installation.
I actually happen to have a brand new AEM 30-0310. Does this work also? I have no problem running it to a prolink cable but if I can get the data off the obd port from the ecu I don't have to run wires through the windows and shit when I am logging. The one you stated looks lile.ypu need to use the garage, I have nowhere to put a guage
like he said, you can hide the gauge and just run the obd2 cable so the data can be pulled up in hptuners to datalo AFRPrice of the cable I will probably just but a 0334. I just wonder if garage has to be hooked up to work or if I can use without gauge
