ISTA Install Help

Thu Jan 30, 2020 12:33 pm

I'm kind of a putz when it comes to PCs (Mac guy) and I've never done any car programming before. I've searched for a while on precise directions for an i3 and haven't found a lot. I've found plenty for other models of BMWs. Anyone willing to help me out? I'm sure I'll have follow up Qs.

- Do I need an ICOM?
-Which version of ISTA do I need for a battery reset? It looks like there are many versions.
-Can it run on Windows 8?
-If I get a laptop below min spec will it work? Im buying a PC just to do this, so it'll most likely be a used old crappy PC.
-Hard drive space is around 200gb, correct? Can I use an external?

I did a search on this forum, couldn't find what I'm looking for.

Thanks!

Hi,
I had the same sort of trouble getting accurate and useful to BMWi info
You might want to start with E-sys - instructions here https://www.bmwblog.com/2014/10/11/codi ... ctric-car/
The general BMW sites dont seem to be helpful but software for F30 seems close enough to work with i3
https://www.bimmerfest.com/forums/forum ... .php?f=175
http://www.bmwcoding.com/forum.php

From what I read you wont need ICOM for ISTA

I got an ethernet to OBD2 cable from Ebay and ran E-sys with tokenmaster within a VMware VM on a Dell 780 PC
The VM is to do with keeping the date from expiring when you start a new session as the token was set that way there is a lot of BS about this

I think you can setup the battery in E-Sys; I have nervously done the radio coding to enable AM, turned off the seat belt warnings
The amount of settings available for lighting - DRL and halo lights - is too much for me to follow it goes for 4 pages
This is where the generic cheat sheets are hopeless on the i3

My last job is to get the maps NAVI to work here - none of the experts on the other forums have been able to state exactly what is required (other than blindly add money)

I, too, am a Mac-only guy who is investigating running ISTA+ to get information about the state of the battery pack of our i3. I started by downloading the Beginner's Guide to ISTA+ as described here. This describes how to download and install ISTA+ as well as suggesting PC hardware requirements.

This YouTube video might be a good resource for installing ISTA+.

I have read that ISTA+ 4.10 supports reinitializing the BMS to temporarily increase the battery pack's usable capacity. I have downloaded ISTA+ 4.10 from the Mega.nz Website after installing the MEGAsync app on my MacBook.

Unfortunately, I can't provide any information about running ISTA+ because I haven't bought an old Windows laptop or the required OBD to Ethernet cable.

I made some progress this week. I bought a '17 Gateway with a 2.2ghz single core Pentium, 4gb ram, 500gb hard drive for $60. Not bad I thought, though its a tad slow with a single core.

I paid $8 for an ebay download since it was a single click, self automated installation process only to find out its the latest version of ISTA+ which doesn't have battery initialization. Oh well..

Found a 4.10 version of ISTA+ which has battery init. at: https://www.car-auto-repair.com/bmw-rhe ... 2uw-Nu7bBA

Installed easily, should have started here. The program seems to work, though its titled "ISTAGUI".

Any instructions to do the battery from here? I'll go back and read the instruction links posted. I hope I dont brick my car this weekend, my wife will be pissed :?

EDIT: @MagicCarpet I just clicked on your links and those are not related to ISTA. Not sure what that program does, but it seems very close to what the iphone app does that requires zero coding or risk. If you just want to change minor settings check out Bimmercode. This app seems idiot-proof.

There are diiriections out ooon thhe web for how too iinstall a Windows duaal-boot partiitiooin oon a Macbook. Yoou can ddownloadd Winddows foor free, andd itt will work for 30 days without a license andd nag you to buy oone after that, IIRC.

As you can see above, I'm a happy Macbook Pro owner with thhe flaky scissor keyboard keys..... :D

I have 3 Macs I could have used.. I tried to install Bootcamp, but when OSX asked me to install Windows it required a disc to be inserted in a DVD drive. This stumped me for a couple of days, and I googled workarounds that involved coding with Terminal. I tried it, hit some road blocks, and decided that buying a cheap laptop would be easier and cheaper than buying a copy of Windows.

The local pawn shop had a 3 year old laptop for $60, bingo! Not to sound like a Mac snob, but HFS I hate Windows! I haven't used it in 20 years but nothing has really changed. The mouse scrolling is choppy and unpredictable, Windows 8 went through great efforts to hide all the settings, and a million little hassles. Absolute garbage. Upgraded to 10, its a little better. My 12 year old MPB with a SSD dances circles around this POS.

Just finished the battery re-initialization on my '14 60ah i3. In 32 degree weather the Batt Kappa went from 14kwh to 18.4 and range went from 49 miles to 74. Cant wait to see the actual range when the weather is warm! The battery was charged to 100% before using ISTA, and after ISTA it chugged another .6 kwh (while reading 100%). The range increase isn't just in the GOM, its real world. I just drove 35 miles going 65mph with the heater on the whole way and I'm only at half tank. I'm not sure how this witchcraft works, but I'm wondering if it opens up some of the battery buffer to give you 18.x kwh again. No idea, but I'm not asking questions.

If you have battery degradation you must try this!

*I was told to unplug the car during the test and 15 min reset of car, then plug in after*

I have only a MacBook with the crappy scissor keyboard and no Ethernet port. I do have a powered USB hub with an Ethernet port, so I could plug in the required OBD to Ethernet cable. A problem might be telling Windows about the Ethernet port on the powered hub. I know nothing about Windows device drivers and have no interest in learning.

It's got ~145 GB of free space on its SSD for a Boot Camp partition. Any idea how much space a minimal Windows installation requires? The compressed uninstalled ISTA+ requires over 14 GB of disk space, so the installed version would require considerably more space.

My feeling is that buying an inexpensive used Windows laptop would be the most likely approach to succeed and would require only the installation of ISTA+. Of course, I could run into unforeseen problems with a used Windows laptop.

This is almost certainly what is happening. From what I've read, it seems that the unusable low charge level buffer is being reduced in size rather than the high charge level buffer. If so, and depending on how much battery cell degradation has occurred, the voltage of the lowest capacity cell could drop below the level allowed by the BMS before the displayed charge level reaches ~2% where propulsive power normally begins being reduced. This could leave one stranded.

I would like to know your experience driving at very low displayed charge levels.

I question whether the reduction in usable battery pack capacity is totally due to battery cell degradation or whether some or most of this reduction is due to the BMS gradually increasing the size of one or both unusable capacity buffers, maybe to decrease the cell degradation rate enough to minimize the number of battery capacity warranty claims.

The Batt. Kapa. max values and actual range values of our 2014 BEV having been driven only 10k miles under ideal EV conditions have dropped ~15%. The Idaho National Laboratory measured an average of ~7% loss of battery pack capacity on 4 2014 i3 BEV's after only ~15 months and ~12 k miles of driving, so the capacity loss on our i3 seems high unless degradation over time is a major factor. This makes me wonder whether the BMS is responsible for a significant portion of our range loss rather than actual battery cell degradation.

I have installed the server versions of Windows on 40 GB of disk with plenty of breathing room. Windows might automatically install the drivers for the USB-connected ethernet port when it sees it.

In the long run having a junker Windows computer may be the best bet. I keep an old Win7 notebook from work on my bench, and use it to program network switches, flash updates into my 3D printers and other electronics, and program amateur radios for myself and other licensed hams.....

I like having a junk PC just to download programs like ISTA off the web, where I wouldn't want to chance using my work Macbook Pro getting viruses on sketchy servers. My single core 2.2 ghz Pentium with 4gb of RAM and 500 gb of 5400RPM storage worked fine. It was only 3 years old somehow (and Macs have been using quad cores for what, 6-7 years?

I plan on driving the i3 a lot tomorrow, so I'll keep you posted about how the battery does on the bottom end. I'm trying not to get my hopes up too much seeing as how I went from 49 miles yesterday to 82 miles this morning... in 34 degree weather! In the fall I drove the car home from the dealership in 70 degrees and I got 74 miles in EcoPro+ going 55mph the whole way. We'll see!
