Still trying to define the scope of the problem.
According to this :
RC Injector Tech Note
written on 10/1998
"At this time, - 90% - of all automobiles, including the Japanese, are using Saturated - 12 to 16 Ohm Injectors. Toyota uses Sat. injectors in all but the Turbo Models"
I wonder if he means new automobiles being built or of all cars on the road in 98, only %10 were peak and hold. But it sounds like most folks can make use of it, but I would like to find a generic fix for the %10 peak and hold crowd.
