The adjustment screw on the Manifold Pressure Sensor (MPS) came from the factory with a plastic protective cap, intended to […]
Bung installed – $40 at an exhaust shop. Here is the O2 sensor installed Connected to the 14point7 Spartan 3 […]
We know that the MPS changes the pulse width based on the manifold vacuum and the atmospheric pressure. Testing for […]
Which is best? This chart shows @cushjbc ‘s factory calibrated MPS (green) and my Wideband O2 calibrated MPS (red). The measurements have […]
In this topic I will describe how the D-Jetronic basic fuel injector pulses are created with the aid of circuit […]
I previously wrote about how to simulate an MPS in KiCAD. Here is how to tweak the model to match […]
This is version 2 which allows the vacuum to be varied over time during the simulation. The circuit simulator – […]
I recently started to suspect that I had made a mistake with this simulation, getting the timing of the outputs relative […]
The TPS takes the position of the throttle linkage and generates four outputs: When the throttle is 2% or less […]
Here is a simulation of the air and coolant temperature sensors using SPICE and KiCAD. All of the heavy lifting […]
