i just installed the gauge and love it ...its a must! but i was wondering 2 questions first is that i put the misfire parameter up and i dont think its for out cars...because i have a brand new engine runs great... and if i rev it it always says 2 misfires and i dont believe it is at all ...i was just wondering i take it that the misfire isnt for our cars?..... second question is ...isnt there suppose to be like and idc ..injector duty cycle ...parameter on it ...for my injector percent?

 

engines have misfires all the time, whether they be small or just a fluke that the computer recognizes. as long as it is not a constant misfire you will be fine. and they have injector pulse width, which you would need to calculate out for your IDC's

 

yeah if i rev mine above 3 grand it always misfires...and it does most of the time when i get on it but no dtc's.....but how do you do the calculations.....mainly i want to see if they are maxing out or how close they are to?

 

okay you are going to multiply your (injector pulse width x 5.33)=XXX and then RPM/XXX=IDC%

 

k thanks man!

 

good thread
