How about postmaster(a)gravelrash.com, seeing as it seems to be his domain? BTW, the guy who just took my Nordwest away is racing at Jurby next Sunday. His first time. Riding with a mate who lives in Peel. Small world innit? Still not certain if I'll make it. Cough going deeper and yellow clag returning. I'm off to the quack tomorrow. If he gives me antibiotics of the right kind first go I may be OK to travel by Friday. -- +----------------------------------------------------------------+ | Pete Fisher at Home: Peter(a)ps-fisher.demon.co.uk | | Voxan Roadster [Heh Space at last!] Yamaha WR250Z | | Gilera GFR * 2 Moto Morini 2C/375 Morini 350 "Forgotten Error" | +----------------------------------------------------------------+

You're completely wrong. The immobiliser logic is *in* the ECU. The external device is actually called an 'immobiliser amplifier' - it takes the signal detected from the chip in the key, er, amplifies it, and sends it to the ECU. The kit ECU doesn't even have the immobiliser/key matching stuff in it. -- Champ We declare that the splendor of the world has been enriched by a new beauty: the beauty of speed.
