WTD: 70amp+ Power Supply

Sensible_ · 05-09-2013, 06:12 PM

Looking for a 70amp PSU capable of 13.8v DC Output for ecu programming.

Many thanks!

Boat battery?
Car battery and a float charger?

70A eh?
How many ECU are you programming, about 40 a time?

Sorry, I don't understand. I am looking for a power supply capable of supplying a stable 13.8v with the potential for drawing up to 70amps. Are you offering this?

That will be bloody expensive.

Afaik BMW only recommend 40A for coding.

I thought for e90 they recommend 70a? As far as I'm aware that doesn't mean a constant 70a - it depends on what it draws, I've heard a basic e90 can draw up to 60amp, a higher spec will obviously be more...

Yeah some of the batteries are around 80A IIRC

Im also looking into a power supply as well. I bought AA's tune recently with their Simon Tool & it was recommended that I connect my car to an external power source while the Simon Tool reads the ECU & uploads the tune file

I'd love your input! THanks!

I'm still looking for a cheap solution for this.

Bargain!

I use large PSU at 12v for my ham radio station but rarely need more than 30A at 12VDC.
These supplies typically run to about £120 or so so the above is good value from HK.

I did look at that however the output voltage only goes up to 13.2v - not the 13.8 as recommended
