Guys, I am starting development of a hobby project which will read a vehicle speed and do some stuff (Alarms for example) the project will eventually be PIC based but to get an understanding of 'real' things going on I am trying to find a Scantool to help. There are lots of ELM327 clones available from China but my research has helped me in deciding to keep clear of them. Other tools available in the UK vary in price (dramatically) and although my time for this application is free, I still don't want to waste a lot of time with inferior hardware. The ELM327 (V1.3a) based tools seem to be entry level and only upgradable by chip change, there seems to be some 'compatible' tools that are flash based and easy to upgrade (generally free). The Elmscan5 seems like a good contender but the UK prices from distributors is high compared to direct, obviously the direct route may attract some import duty and the dreaded VAT. Any suggestions, recommendation's or 'keep well clear of's' will be greatly received Cheers Dave (G0GMK) g0gmk at btinternet dot com -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
