Another fake engine tuner - but with a neat circuit
🕑 Added 2023-10-05 04:20:23 +0000 UTCThere are a huge number of these units available from many sources. This one is reassuringly fake, but with a nice twist in that it uses an op-amp as the oscillator used to flash the "data" LEDs.
I wonder how many people are convinced that these things work.

Tesla's, at least the model 3 don't have OBD connectors. It was the first vehicle exempt from that requirement. Funny story, I used to have a classic 1973 Datsun 240Z. Once when I took it for the yearly emissions test, the young lady told me to get out so she could plug in the OBD cable. I had to explain to her that the car predated OBD, and probably her as well. They had to do the tailpipe sniff and she had to get a supervisor to show her how.
