And I'd like to see someone with a diesel try it thoroughly.... I've tried it on the GEMS P38s of two stranded owners in recent weeks - nada - and extensively tested it on mine in the last 72 hours. Wd be nice to see some evidence that this phenomenon actually exists in a diesel, using a production Nanocom. But since Wammers is guarding the secret formula, then there's little hope of that. At the end of the day - it doesn't matter so much - unless a hapless reader here is tempted to lash out £500 on a nano, on the basis of this unique capability - not realising that it is, at the very least, "very hard" to achieve
