Power Supply for DIYer's - BMW 3-Series (E90 E92) Forum

Sensible_ · 02-17-2013, 09:15 AM

Hi,

I'm looking to step up my coding/programming a bit. And am now using ISTA/P.

Im looking for a reliable / cheap power supply (BSU) for programming. Ive read through the recommended list of PSU's and almost fell off my chair with the prices!

Having searched I've seen the following are recommended by DIYer's:

Schumacher INC-700A - $427
Snap On EEBC 500 -$550 (approx)

Im looking for something even cheaper! So, anyone got any recommendations for a cheap 13.8v 50/60/70/80amp PSU?

Would this do it? For $129 it looks a bargin!

Are you doing coding (ncsexpert) or programming (winkfpt)

Sensible_ · 02-17-2013, 01:24 PM

Neither. Programming with ISTA/P - i.e. full up upgrades. I'm trying to move away from inpa, ncsexpert and winkfp. Sometime you've just got to move forward.

He is using ISTA-P which is dealership software...

Hey Guys,

Found these. They look High Quality. Anyone know how many amps would be needed for just DIY home stuff?

BMW recommend 70amp for e90. For the new generations F series they go for 80!

I did a complete update a while back with SSS Progman. It took all night and my 50 amp Astron kept up (pegged the meter when I first hooked it up but settled down to about 30-40 amps) so you should be good with 50 amp or better. If you can, go with the recommended 70-80 amp though; Astrons are pretty much bullet-proof and could handle being pegged at 50 for a few minutes until it settled down. I don't know about some of the cheap switching PS's.

Nice, thanks for the info. What spec is your car? I believe the load will greatly depend on what modules you have. If yours is top spec with idrive etc etc that astron sound great. How much did you he it for?

GenePoole · 02-18-2013, 02:23 PM

I have almost all the options available on the 2006 on mine so I have a lot of modules. I've also added a sat radio and alarm for 3 more modules.

I'm not sure where I got my 50 amp Astron actually. I have about a half-dozen various Astron power supplies and another half-dozen other brands. I'm an Amateur Radio operator and I've picked most of them up at ham-fests.
