Just a few questions

[progamer1233]

Hello,

I just have a few questions about flashing ECU's, im doing this now for one year and im using tools like ktag.

1. Before I remove an ECU from the car I always disconnect GND from the batterie but is this really necessary? I think it should be enough if I just remove the key and wait a few minutes and then unplug the ECU.
What do you guys think?

2. While flashing an ECU how do you set up your power supply? I set my power supply to 12,9v and 5A. I know that some ECU's need more than 1A or 2A. What settings are you using ? Is 12,9v and 5A enough for flashing?

Thank you for ur help!

1. Thats laziness talking

2. No thats not right at all

You want a maintainer

You set its voltage and it keeps it precisely there without fluctuation regardless of how many amps it is pulling

Maintaining the voltage precisely hence its name
