Steve Colwell Subject: [LML] Re: Electronic Ignition System Application Chris, Yes, part of the problem is induction/mixture differences caused by the throttle plate position. I.E. WOT may be a quite different distribution than at partial throttle. Uh, switch over to injection. Then you only have to deal with injector engine position locations resulting in differences in atomization of the fuel because of variable upper cowl air flow/pressure.
