I'm looking to clip a 5v reference signal. Let me better explain my problem. I have a turbo diesel engine and I want to keep the PCM from seeing true boost pressure. The ideal circuit to wire in line of the signal would be adjustable and work as a voltage low pass filter.
For example
Signal range is .65 -4.65 volts. I only want .65- 3 volts. Is this possible?
