How do you measure duty cycles with a snap on scanner. ALSO where do you get the definistions for the terms you guys are using for prom burning. Thanks for all replys MR KIDD

Just compare the actual pulse with with the possible. At 6,000 rpm you have 10 msec posssible duration, if the PW is 8 msec, then you have an 80% duty cycle. at 600 rpm 100 msec. If you have a PW of 2 you have a 2% duty cycle.

Just have to read and get familiar with the language, the is a FAQ at DIY_EFI but the site is down for the moment.
