Evey time I looked at this thread I cringed at the references to low impedance injectors as peak and hold but it's a very common mistake and didn't seem worth mentioning. |
The reason for my post was that when I first saw the thread, I thought someone had come up with a piggyback Peak/Hold injecor drive circuit for TT but was disappointed that this was really a NA -> TT ECU upgrade thread.
Haven't seen any hard data but my theory is that a Peak/Hold would provide more precise injector timing.
