2002 Lexus is300. Northern Michigan, I plan to do a 15 - 20psi na-t build. I’m looking for anyone’s help or opinions with this build as I’m learning and researching all myself. Here is my car: (Last pic shows the current rims, just peeled paint off that the last owner put on)

yea i found out about combo sensors surfing Platinum Racing's website, they have one that's by Syltek it's even smaller than bosch and has a steel body that's already 1/8 npt threaded and has Deutsch connector for only $125 cuz strong USD but you have to catch them with free shipping deal cuz they're in Australia

Just in case you wanna make that oil filter adaptor mount even fancier yet...

Bosch now makes a combined oil temp/pressure sensor that'd fit right where your existing AEM oil pressure sensor fits...

Bosch Combined Pressure/Temperature Sensor

Combined pressure and temperature in a single sensor. Perfect for oil temp/pressure, coolant temp/pressure, or fuel pressure/temp. While the sensor itself is threaded M10x1.0 and uses an odd, tapered seat, included along with the connector and pins is a 1/8 NPT adapter. A 1/8 BSPT adapter is...

I'm not sure what AEM gage you have; is it a CAN gage wired to your ECU?

If so, using this different sensor would be simple. There's a good chance it's already a selectable choice in the Haltech software...if not, you'd just have to key-in the characteristic values of voltage/pressure that are included with the new sensor.

You'll also need an analog input to hook up the oil temp part of the sensor - this is two different sensors built into one - but it's still sending two separate signals to the ECU.

@keagan22 on the remote oil setup, do you have the lines routed out-out & in-in, or out-in & out-in? It’s hard to tell from the pics but kinda looks like you have it wrong.
