Or will you have a reference else where? no, i dont need to know what the 'actual' level is when im adjusting it. it will be simply be adjusted as a preventative measure for knock elimination, so will be set subjectively against that (not any masurable manifold pressure or anything)... Cool1 wrote on Wed, 10 September 2003 18:39 For just one output a simple adjustable voltage divider will do the job and do it rather well Smile And I personally wouldn't use a relay to switch the injector, I would simply use a FET built into your main circuit. want to design me a circuit? it really just needs to take a variable 0-5v dc input, and switch on an output at a given input voltage - which needs to be adjustable. whats a FET? this thing is going to be hooke up to a bunch of other relays, so maybe a relay is easier - just so my simple mind can integrate the whole system? cheers ed [Report message to a moderator]
