Whittock1 Posted September 4, 2010 Report Share Posted September 4, 2010 Hi I was wondering if you can help I have a rpm counter for my car it's reading to high is there a way of wiring a componet in line from the coil to the counter to reduce the time down to match the counter. On the back off the counter there is a switch to adjust the led display 4 6 8 these donate how many cylinders you have on your car, select the amount of cylinders ie 6 then set the switch to correspond to that. My problem is I have a 12 cylinder and the settings only go to 8 max. If I set it to 4 it reads 5000 rpm (when at idle 1000) when set to 6 it reads 4000 and when set to 8 it reads 3000. Can it be done ? I'm guessing if it had more settings ie 10 or 12 it would just keep coming down till the readings were correct. Cheers . I forgot to mention the pick up is from an alternator it puts out a 12 v signal which is switching the faster the alternator spins ie revving the quicker the signal becomes.

Hero999 Posted September 4, 2010 Report Share Posted September 4, 2010 It's possible that passing the signal through a divide by two counter and setting the numbver of cylinders to 12 will work. Quote Link to comment Share on other sites More sharing options...
