Hi everyone, my understanding is that the Schumacher INC-70A is one of the most popular power supply units here and should be sufficient for my e90 and e92. But my question is, before I pull the trigger on it, will it also be good enough for my F15 x5? I don't run a business, it's just for my personal cars. Thanks.

Yes, I've been full flash my friend's F15 X5 30d by ISTA/P with Schumacher INC-70A, all fine.

So my unit arrived, how many volts & amps should I set it on when I do coding? Also is it the same on programming?

Anywhere between 14.0 and 15.0V.

However, the unit will determine the amps up to 70amps to maintain voltage.

Not above 14,2V for high voltage (V)
above this voltage IBS begins to correct voltage as well as voltage regulator, which is not good for these systems at full power supply,
extra rechargeable battery maximum current of high amperage
which may lead to damage at too high a voltage.
encoding just above 13V to 14V, the constant current
and programming 13.5 to 14V direct current supply
average 13.8V,
13.8V voltage sustain a, it is the most safe for the battery and alternator and its systems

I have the telwin doctor charge 50, it has max 40A with supply, diagnostic and more mods

Are you happy with the Telwin Doctor Charge 50 ?? is 40 Amp enough to code and flash the car? Can this device keep providing 40 Amp constently even when the ignition is on??
 Iam thinking of bying the same device.

Best regards

I would consider MAAS SPS-50-II. I got it currently and it's working fine. Only issue I see is that it is only 50A constant and 55A max. Adjustable from 9-15V. If 50A is enough for you then it's pretty good option it costs ~150€. I'm currently considering getting a server PSU that can deliver 140A.

I've actually considered the by you recommended powersupply as well.
However, I've had contact with the manufacturer (please note that this unit is sold by different brands) - and that it was NOT advisable to use this product for programming.

The response I got (translated, as the conversation was in Dutch): "Our experience is that the battery doesn't always gets the 'big blows' in power draw and that this would use the safety too much - sometimes leading into blown fuses or worse"

But allot of peole are using this device the MAAS SPS-50-II , specially on the German forums like Motor Talks.
They are all happy with this device , i am considering the Telwin Doctor Charge 50  but asked here for some advice from peole who are using it bud sofar did not get any.

Very good Power supply´s - up to 120A

I know but just for ones in awhile to code and flash the car is this charger to expensive. I am no professional that makes a living with coding and flashing cars. So looking for an aforthable charger with power supply . Or something like the MAAS 50 II just a power supple who can go to 50 AMP .

[TBGaming]

I bought two years ago the MAAS 50 II on eBay for 90 EUR, definitely a good value at that price. I flashed an almost full spec f32 without any issue, the car wasn't even assorbing all 50 amps.

I've made a PSU with 12-16V and 55A from a server power suply.
I've added also an voltamper device and noticed that with ignition on and engine off, it stays somewhere in 42-44A during flashing/coding.
The car has 33ECUs so they are quite a lot(Hud/hu2 evo edc etc).
So a 50Amps PSU should be fine from my pov
