	Current draw for a ME7.5 while programming? « on: April 24, 2012, 11:55:40 AM »

Just curious... anyone ever take the time to measure current draw from the ECU when programming? I'm building a bench harness for myself and want to make sure I don't cheap out on the AC/DC power supply... but I don't want to get a 10A one if it only needs 500mA.

TIA.

Its very negligible (probably < 300mA, but i haven't checked) . just make sure the power is super clean.

Maybe I'll just build a small two transistor SMPS or something then. Cheesy

Mine is usually around 230 mA.

best is to buy a little cheap-o motorcycle or automotive battery. This will ensure the power is super clean. Power supplies tend to output see-saw and square crap.

Power doesn't need to be as clean as you think...

Better safe than sorry.
