Review on HOTSYSTEM Electronic Universal Pressure Automotive by Mar Pacora

Well what can I say. Had to be modified to install a censor on my Chevy 383 engine. After I plugged it in, I'm really not sure, but I think so. I'm not reading the correct psi the motor is outputting. When I use the heater or air conditioner in the car, it affects the PSI output and makes it too low. Can radio frequency interference occur? Not sure what it does, but it's not sure. And the light at night will blind you, you had to change that by cutting the sedan window film to cover the front of the sensor to reduce the glare for night driving and still be able to see it in daylight. In general, I will not buy any of my cars again.
