I have been going shithouse lately between posting things and doing things to the Delica. This thread is for my latest install. I have wanted to turn the boost up for a while now, but I refused to do so without proper engine health monitoring. Therefore, I required a proper EGT and Boost gauge. I did not, however, want two seperate aftermarket gauges present on or around the dash. I like the factory stuff and little else. So my search began. I found a cool line of products made by a company called PLX Devices. They have been producing high quality wideband monitoring products for a long time. I actually have an old LM300 digital wideband in my Lexus IS300 2jzGTE swap. Anyway, here is what I bought.

Now, this setup is centered on a touchscreen gauge that you can buy. The idea here is to buy whatever sensor modules you want, string them all together, and broadcast their data to one gauge. Cool right? It gets cooler. They recently released a bluetooth application/dongle to allow streaming of sensor data to a freakin android or iphone. EPIC. This install uses the latter combination. Here we go!
Step One. Remove the damn panel again.
Step Two. Locate your EGT Sensor Probe install location.... Do you have an EGR Bypass?!?! BOOM!
Step Three. Remove your EGR Bypass plate and start drilling. It tells you what size bit to use.
Step Four. Tap that ass
Step Five. Install EGT Probe as far as you can into the plate.
Step Six. Install the plate and sensor probe back on the manifold.
Step Seven. Locate Power and Ground for your Sensor Modules. I choose the 12V Ignition-Switched Solenoid on the back of the firewall for power. The sensor modules collectively draw under 5 amps so stealing power from here shouldn't be a problem. If you had a Wideband Module I would NOT recommend using this power source. Find a stronger power source as wideband sensors suck up some juice. For the ground I made a ring terminal connector directly to the negative terminal
Step Eight. Did you buy the Boost Sensor Module? Obtain a vacuum tee and tap into the feed running into the top of the injection pump. This comes directly from the turbocharger compressor housing.
Step Nine. Run the vacuum, EGT Probe wires through the small opening near the back of the firewall entering the battery well. Zip tie everything onto the main harness that runs into there.
Step Ten. PROFIT. This is a screen shot from my android phone showing actual sensor data during driving! Freaking sweet.
