I am developing a mobile app to do some OBD2 tests and monitoring via bluetooth and i want to write some OBD2 commands inside a for loop, in a interval of a second (1000ms) or even less. Is there some chance of damage the ECU of my car or some limitation (number of written commands to x ammout of time) in the way the ECU could answer to my commands?
You’re not gonna do damage, if it’s too much it will more than likely just stop replying.
When programming an ecu it communicates about about 1 message per millisecond. So I’m sure a few messages every second will be nothing.
