Wed, 10 September 2003 08:42 as far as the circuit goes, it looks okay. i would beef up the 'lash-back/flyback' portion, as the voltage spikes of closing injectors has proved to be larger than ppl usually expect. there is a flyback design on the main MS site (and i prolly have it somewhere) but apart from that, it's a simple comparator circuit that will probably work okay. concerns would be difficulties with latching on/off at the switching point... if it keeps flapping around, could be interesting, with voltage spikes and stuff. if you are thinking of this for water injection, it looks good. for extra fuel.. hmmmmm but it looks pretty interesting and worth a go Cya, Stewart [Report message to a moderator]
