I have an ELM based OBD scanner I've used on my old cars without trouble, but it seems some newer cars, including my 2008 451 are not happy with it. Most of the functionality works, I can read and reset codes, see live data, etc, but it causes trouble lights to flicker off and on while it's in operation. Since my desire is to collect data as I drive, this isn't very helpful, so I need to look for a replacement.

What OBD/CAN adapters have been shown to work well? Preferably, Id like bluetooth, wifi, or USB, but so long as it can log the data I'm willing to entertain other suggestions.

I've picked through a number of past threads, but most I have seen focus on either clearing codes or in regard to ScanGauge/UltraScan specifically, not that I am opposed to ScanGauge/UltraScan, just that I'd rather be able to access the data so I can mangle it my way.

Anyone else out there logging through the OBD port? What are you using?

Given all of the suggestions, I did more reading of various forums of opinions on various manufacturers. So many make various claims which are hard to substantiate, but I'd narrowed it down to the iCarsoft MB V2.0 (not the MB II, that's an older product) and the Autel MD808P. I was inclined to get the Autel, as it works on a much wider range of manufacturers, but couldn't confirm to my satisfaction that the MD808 could do all the same functions as the iCarsoft for Mercedes/Smart and ended up getting the iCarsoft because it was cheaper and (I think) does more on this car.

Initial impressions are pretty good, it can scan the CAN bus and read/clear a number of modules. It recognized for the following CAN modules:
N3/15 (ME-SFI[ME] Control unit
N15/6 (Sprintshift control module)
N10/10 (SAM control unit)
A1 (Instrument Cluster)
N47-5 (ESP Control Unit)
N15/6 (Sprintshift control unit)
N2/7 (Restraint System Control Unit)
N23 (Heater/AC operating unit)
N15/5 (Electronic Selector Lever Module Control Unit)
N8 (Tire PRessure Monitoring System)
N110 (Weight Sensing System (WSS) Control Unit)

Hope that helps someone along the way.
