Please share your feedback if you change these values!

Module | Parameter | non-ZCP | ZCP
VDC | Fahrzeugtyp | F80 = 0F | F80_Comp = 27
VDC | M_Competition / High | 00 | 01
ICM | IcmKod_I_Karosserie | 0C | 1A
DSC | C_Variante_Fahrzeug_e | 00 | 03
DSC | DSC_CODIERDATEN_RDCI_18_18_2 | nicht_aktiv = 00 | aktiv = 01

I assume you have to have your car updated to 58.3 to make these changes. My car is a MY16 September 2015 build so I would need to find a dealership to update my software?

My car is at 58.3 but the coding parameters should exist at anything past 58.0

My car was a November 2015 build, and it only had 57.2 on it.

I am building a power supply to allow me to update the car on my own, so I'll give this all a try in a few weeks hopefully.

Maybe a noob question, but how do you find your current software version? I've seen in some threads where you can find the version in Esys, but the numbering sequence looks different.

What was the sw version on your car before 58.3?

So in that example is the I-level 55.0?

[TheElementalCashew]

That was the thread I was referring to. Probably another noob question, but how does the I-step translate to the versions being tossed around here (58.x, etc.)? I appreciate the help, I'm new to BMWs and coding.

15-11-505 (57.x) then 16-03-501 (58.0) now 16-03-504 (58.3)

That's a good question, for that you need a document called ISTA/P VERSION AND I-LEVEL OVERVIEW, usually Shawn has them. Here's a screenshot from ISTA/p 3.56, an older version so you get the idea, look under the column for F020.

As an example, my cars current I-step is F020-15-03-503, so that would correspond to 55.3 (June 15 prod)

No way, F001-08-09-550 is way older than that. Check the screenshot I attached and you'll understand the mapping. I don't have the recent mapping tables as I don't need them but you can ask Shawn for it.

Hmmm so it's interesting that you didn't experience any improvements when you jumped to 58.3. Do you have DCT or 6MT?

Take note of the BMW charging parameters for the LifePO4 batteries we have: http://www.bimmerfest.com/forums/sho...1&postcount=44

Are you starting with a computer or ham PSU? Or building from scratch? A nice expensive model I am considering buying is the Schumacher Inc-700A but the jury is still out if it's suitable for our special batteries.

Thanks man. I sent Shawn a PM.

I use the Schumacher INC-700A charger when flashing set to "cpu flash mode" (constant voltage) of 13.5V. No issues to report at all.

The only change from 58.0 to 58.3 in my car (01/16 build date) was an update to NBT2.

I'm going to be using an older server PSU with a huge 12v rail (47A) and APFC. There's a video on youtube of someone load testing it and it runs fine up to 55A. One should be enough, but I got two for 20 on ebay so I'll run them in parallel. They have a current sharing pin that you connect together and they split the load evenly.

I will put a 1k ohm pot on the 12v sense pin, which allows me to up the voltage to 13.5-13.6 ish. The PSU has over voltage protection at 13.8v.

If you're interested, it's called the DPS-600PB. This is a very popular power supply that people use for charging RC lipos because they are so cheap.

Thanks for pointing out the charging parameters. I actually gleaned that info from your Rheingold battery pdf already and decided this would work.

OT: That's interesting considering that BMW recommends 14V charging voltage for our batteries, and 13.6V for maintenance charge voltage. As for the inc-700A, in this site someone said its for lead acid batteries only... http://www.batterychargers.com/inc-700a/

But now that you say it worked with no issues, and with a lower flashing voltage, not sure what to make of BMWs recommendations for flashing the LifePO4 batteries. Or maybe 0.4 V shouldn't make a difference in flashing...
UPDATE: disregard the above info as it is pertinent for charging and not flashing/programming.

If the 700A can supply enough power at 13.5v, the voltage will not drop below that. 14v is the voltage applied if you're trying to charge up the battery. For programming, we don't really care as long as the voltage is high enough for the flash memory to write correctly, which is probably near or slightly under 13v.

I believe I read that ESYS has a 13v minimum voltage before it begins any flashing operations.

The 700A in CPU flash mode sounds like basically what I'm going for with my DIY PSU. High enough voltage for flashing, not overvolting the lithium battery, and supplies enough amps that the voltage will not drop.

The thing i'm curious about is how many amps the 700A supplies while in CPU flash mode. I definitely would not run it in normal charging mode because lead acid batteries seem to usually charge at 14.6v.

terahertz , that makes sense! The document that I got from Rheingold was for charging and not programming, hence the confusion. Thanks!

Seems to supply around 20-25A @ 13.5V when flashing. I only use the flash programming mode with my M3 and have a ctek lipo charger if charging is necessary.

But that's what it supplied when you were flashing, I sure hope it can supply more... Depending on the equipment and nb/type of ECUs, I've read close to 30-40Amps may be needed. Btw, what ECUs did you flash? and how long was your flashing session(s)?
