Ok I know this might open up a can of worms but I need a new scan tool or to update mine. I have a Snapon mt 2500 but the 1800 to update is a little far fetched. I have found one that says it will do every thing I was wanting to know if any body has used it. AutoEnginuity® - OBD2 Scan Tool - Professional PC and PDA Diagnostics thats the web address for them. Let me know what you guys think. I run a small part time shop I am very busy (I am cheap at $35. 00 an hour) but I am not a full time so I don't want a 2000 plus for a scanner that I only use 2 or 3 times a week and primarily on diesels witch a lot of scanners don't like.
