ajazyasin Posted December 27, 2006 Share Posted December 27, 2006 A pressure switch. If pressure drops below the pre-determined value, the ignition cuts. Quote Link to comment Share on other sites More sharing options...
TLicense Posted December 30, 2006 Share Posted December 30, 2006 OK, here's what the guy I work with has come up with:- Basically you pass the power wires to each pump through the centre of the blue component:- Then you set an upper and lower current range that the pump should draw (say 15amps lowest and 25amps highest - need to check on these) on the two rotary potentiometers:- And then if the current draw from the pumps go out of these two limits it will provide an output (5 volt IIRC). That can be used to light up an L.E.D. or if you have a standalone ECU can be used to increase injector duration or cut ignition or whatever. I think it ended up costing less than £40 (Again would have to check). What do you guys think? Could it be a winner? Quote Link to comment Share on other sites More sharing options...

bondango Posted December 30, 2006 Share Posted December 30, 2006 ferk me thats well thought out. Defo would have it using a relay to cut ignition - £40-£50 Vs rebuilding a det'd engine, i know were my money would be. Quote Link to comment Share on other sites More sharing options...

RobSheffield Posted December 30, 2006 Author Share Posted December 30, 2006 Anyway, fuel rails eh Quote Link to comment Share on other sites More sharing options...
bromy Posted December 30, 2006 Share Posted December 30, 2006 I know where to get the rail material from that is exactly the same as PHR -10AN 17mm inside diameter rail, and could machine them if I had one as a sample to work to very easily Quote Link to comment Share on other sites More sharing options...
Terminator Posted December 31, 2006 Share Posted December 31, 2006 My BL rail is 17.4mm internal. Tony I would be interested in this little bit of electronics. I quite like the idea of spark cut. I wonder if AEM would respond quickly enough to AFR's going near fatal. Quote Link to comment Share on other sites More sharing options...
