Technical OBD2 ELM323 connection problems

What software are you guys using to read the diagnostics on the Stilo (JTD) and are there any special settings?

I have an ELM323 adapter but it doesn't seem to work using Scantools, ScanMaster or Obd2spy. The software recognizes the ELM adapter ok, but I get "NO DATA" from the ECU.

I can talk to the ECU using the "raw" ELM commands in a terminal session, but only if I use the fast initialization method (ATFI). Using the slow initialization I get -
>ATZ
ELM323 v2.0
>ATSI
BUS INIT: ...OK
>0101
NO DATA

whereas the fast initialization gives-
>ATZ
ELM323 v2.0
>ATFI
BUS INIT: OK
>0101
41 01 00 06 80 00
>

I have also tried forcing the protocol in ScanMaster to ISO 14230-4 KWP (fast init, 10.4 Kbaud) but it still is unable to connect.

Anyone else had similar problems and found a solution?

Stilo talks over CAN network with diagnostic equipment so you need ELM327 controler.

S'funny, because I just plugged a generic eBay 323 USB unit into my 04 JTD today, and it worked fine with Scantool, ScanMaster & Digimoto. Fascinating to see the engine management data reeling off on a PC screen.
