A DR gauge how to...
 

Title should say AFR guage how to:
Ok, I am going to install Motordyne LT headers (midsize headers) along with resonator TPs and I have always wanted to install an AFR guage but I dont know how the sensor gets hooked up. So my question is...
On the right side header I have a bung and on the right side resonated TP i have a bung, same for the left side...however the z needs all of these for its computer so do I need to have a welder install two more, one on each side...or is there a way to split the signal and have the computer and the guage get the same signal from the same sensor? And if so, before or after the cat (if I had a cat)?

I say you shouldn't put the AFR gauge. Instead buy the AEM X-series OBD2 gauge. It is as accurate as wideband. I have both and after getting the obd2 gauge I tested them both out. Both reads the same no difference.

Wide band cost almost 200 plus installation and wiring.
OBD2 gauge cost 150 and install in minutes.

I have the PLX DM-100 and the PLX boost gauge. The DM-100 Is an ODB2 also but ODB2 cannot provide the speed for decent monitoring. I have also used a Bluetooth ODB2 device with my cell phone and that too just is not fast enough for my liking. My PLX boost gauge is very fast and I will probably buy the PLX AFR sensor as my DM-100 gauge will be able to display all four at the same time (boost, vac, AFR1, AFR2).
