I recently posted on Showdown's thread about using the Haltech ECU to drive the stock oil pressure and temperature gauges, and I thought I’d share my settings here.
In addition to controlling the gauges, I’m using the ECU to trigger the low oil pressure warning light through a conditional statement. This was something I had considered during the build, but I wasn’t entirely sure it would work. Not long after I got the car running, my ten-year-old oil pressure sensor failed. Rather than spending money on a new one, I decided to let the ECU handle the job.
To make this work, I had to purchase a combination pressure/temperature sensor, which conveniently uses the same threads as the oil warning light sensor, making the swap straightforward. The trickiest part was configuring the DPO (digital pulsed output) signals. Since there’s no predefined setup, I had to rely on trial and error. While I’m still fine-tuning the settings, the gauges appear to be accurate
Here's a few photos of my settings.
