GT1's newbie DIS/SSS questions

Just got a set of dis/sss running on my laptop's vmware with some ebay-bought claimed-to-be-german-made diagnostic head and cables. The DIS is not at all user friendly to say the least but at least I got it working properly. Here're my questions for those in the know:

1. is it worthy updating all components' software including the engine management to the latest version available even though the car is running fine apparently? This question's probably a bit redundant since I think the conscensus will be a resounding yes.

2. how do I get to the live streaming part in the DIS, i can't seem to find it anywhere?

3. Acording to the SSS updating software requires a 'bmw-approved' battery charger connected to ensure voltage never drop below 13V, all I have now ia a .75A Battery TEnder Mini trickle charger (got this instead of the regular one per recommendation since I use Voltphreak's lithium battery.) I suppose it's not juicy enough? What's the minimal amperage I need to ensure successful ECU reprogramming?

Thanks

DIS/SSS

As far as the streaming option in the DIS you might need to be more specific on what your trying to accomplish. Are you looking for online updates, ocilliscope functions? The battery charger is not that big of an issue. I am not familiar with the laptop aspect of programming but on an SSS you can view the battery voltage in the upper right corner for terminal 15 and 30. I have used a convention battery charger for programming I-BUS vehicles without any issues but you want to avoid overcharging especially while the DME is being programmed. A trickle charger is not going to cut for programming. Depending on how many times the DME has been programmed software wont hurt but remmeber you only have 13 times to program the DME and it wont accept software after that if there is an issue that really needs it. What version DIS and SSS software came with that? Hope some of this helps and it works trouble free for you. I have had my share of struggles with the SSS and especially now with the new ISIS servers

I believe mine are DIS v57 and SSS v32 respectively.

Maybe I'm not being clear regarding the live data streaming, doesn't that mean displaying live engine/sensor parameters on the fly, e.g. O2 sensor and MAF values?

Maybe it'll be wise if I just replace the tiny lithium one with my conventional lead-acid battery for the flashing. Do I connect the charger to the battery posts directly? According to the SSS I can still flash the ecu 17 times.

1. I think updating modules for no real reason is asking for trouble. If the car is running fine I would leave it.

2. To view live readouts from various inputs, first run a short test. After that click the right arrow at the bottom. Then choose control module functions. There it will list all the control modules the GT1 detected. From there choose the module you want to read data out of and click the name on the left. Then another list pops up. From there choose diagnosis requests. That should pull up a list of various things that can be read. What you can read out will depend on what control module you have selected, so you won't be able to see engine data if you choose KOMBI(Instrument cluster) or some other random module.

3. You will definetely need a stronger charger than a trickle charger. BMW uses Deutronic chargers which maintain a constant 13-14V and vary amperage accordingly for programming. You can get away with a decent charger though set to a medium setting.

1. No, waste of time unless you are having issues with the emissions center in your state connecting to your OBD port
2. There is a subscription service, it's very expensive. This is the way that dealers and some indy mechanics do it. Others just use the old stuff and do fine (so long as they dont need to work on the newest cars)
3. You will most definitely need something stronger. You can find 14V battery chargers out there....or just buy one of the bigger ones from diehard (like the ones on a wheeled cart).

IMO, dont do any programming/coding without supervision until you're very experienced. Im not sure why you'd want to code anything in the first place, unless you're replacing modules or calibrating something.

Be really-extra-super-careful when using a "charger" as a power source when programming. VERY bad things can happen if there is a surge on the line or if the charger burps (happens often). Battery chargers don't have tightly regulated power supplies and can generate fairly strong voltage variations.

Programma and Midtronics both make power supplies designed for programming. I've used the Midtronics 55A unit on an E39 with few issues. On an E60 or E90 it runs out of steam real fast. I recently purchased Snap-On's new EEBC500 Charger/Power supply which appears to have more than enough available juice for my E60.

Ive used the new snap on, it's a very nice piece

It really is... and surprisingly inexpensive for Snap-On (at least compared to the $1500 Deutronic)

Indeed. Im looking to pick one up the next time the snap-on truck is in my area.

EEBC500

Just wanted to let you know my experience with the snap on EEBC500. The Snap-on dealer let me try one for a couple of weeks to see how it would fair for programming. It seemed like a very good price like stated compared to the recommended duetronic. It seemed to work great for the couple of weeks I had it so I ordered 2 more for the workshop. I am not sure what everyone here is using for programming but the new ISSS ISTA-P software is very sensitive to voltage surges. The charger would only supply voltage at a minimum of 14V and was fine at first but then I started noticing control unit failures. I happen to catch one of the chargers spiking to over 15V while programming and crashing control units and yes the batteries in the vehicles weren't low on a charge. I thought it was a glitch in the one unit but noticed the same thing on the other 2 chargers. I contacted the manufacturer and they sent me a replacement that had updated software and so far seems to be working fine so we are in the process of getting the other 2 replaced. The big difference in the updated one is that you can drop the voltage down lower then 14V in flash programming mode. So if you are using the charger or planning to purchase one I would strongly recommend making sure it has the updated software and the only indication I can see is that you can lower the voltage to 13.7 which has worked for me in the workshop.

Good luck with the software updates!
