Power supply for coding/programming. Cheapest solution I've found so far...

[m4f1050]

CbRadiosPronto sells these and in a variety of flavors, like 50amp, 75amp, and even the popular 100amp model.

I bought this model, 100 amp for $199.99


100 AMP CONTINUOUS POWER SUPPLY-CONVERTER-BATTERY Charger 12 volt 13.8 vdc

And a 2gauge 20ft jumper cables for $20.99 which I cut in half and can use other half for a 2nd unit.


Booster Cables 2 Gauge Jumper Leads 20 FT Heavy Duty Car Van Clamps Start US

Making it the cheapest solution, just a little over $200

Hope this helps.

Interesting product. No real info on it though specifying suitability for sensitive computer module programming.

Was intended for RV use so powering 12V accessories. Not sure I would depend on it without more specs available.

There is a reason good quality power supplies are expensive.

You don't need anything "suitable for sensitive computer module programming" as there are no sensitive computer modules. Car power supplies (alternator and battery) are horrifically bad so all the modules in a car are very, very well engineered to not be sensitive to noisy power, voltage fluctuations, etc.

This sounds interesting, especially with the project from @NoQuarter and @fmorelli (and @barry@3DM ) with their DIY charger:

DIY Charging Supply PSU for ISTA+ BMW Programming

I've been working with @Seb335i to set up a programming environment at my place. As we've proceeded we got the point of using ISTA+ to program, and of course my battery charger doesn't cut the mustard. ISTA+ wants to see 13V maintained. Some programming activities can take a long time, and...

I'm not so positive that a computer module doing what it does on a daily basis compared to when it is getting a firmware update that can take a long time is a fair comparison.

A filtering cap would take car of any noise surely ?

Welcome to Spoolstreet! This looks interesting, thanks for posting the information. Part of the requirements come from late-model cars (F10, G series, so on) where ISTA+ seems to have pretty high requirements. @Seb335i probably has a better idea if this solution would work across the BMW's. If so that's a nice alternative!

This is what I use for long flashes and coding. https://www.amazon.com/dp/B01BYFSUJ...olid=1YI87OQSGJ3HC&psc=1&ref_=lv_ov_lig_dp_it

Or a huge lead-acid battery.

Updated post, switched to 2gauge jumper cable wires. And seller assured me that some BMW shops purchased this unit for that purpose. It even has a 3-stage AND fixed output (what you want it to be set) so you can use it to charge (3-stage) OR program (fixed). It has voltage selection from 13v to 16v.

Also, remember when programming, sometimes stuff get triggered, like fuel pumps, electrical stuff, etc etc, you want to have enough amperage (70 amp is what BMW suggests) for that sudden electricity pull, that's why I went with the 100 amp. They also sell a 120amp version.
