Bosch FSA 560 Engine Tuner with Gas Analyser Wanted or Bosch Gas Analyser ETT 836 / 870 / 855 I know these are a bit old now but I still see some classics and like the old way of Tuning. My current Machine a Allen DEA has stopped working and I can't find anyone to have a look at it and finding parts is is pretty slim so I have been advised to go for a Bosch FSA 560, unless someone can fix mine or knows of another one for sale or spares. Any info would be appreciated. I can be contacted on 07890870417 or email me. Chris
