Flyback and Injector Driver Options Discussion.


Intro

Please share your thoughts on each setup below. http://www.vems.hu/wiki/index.php?action=find&find=MembersPage%2FHansK%2FSuzukiSwiftGTIMK%2FFlyBack

So far 30v transient Suppresor diodes and 6.8 ohm resistor seems to be the best setup for Low-Z.


Talking Points

1)What is the best injector control setup for low-z injectors?(Delphi 96#,Siemens 83# and 72#,Bosch 160#)

  • Marcell said: I would definitely use high-Z injectors, and 30V transient diode flyback. That's the easiest to tune, and most smooth idle. It's very easy to bypass the 30V with powerflyback, if one has to tune a setup with low-Z injector in some occasion.

2)What about running an external injector driver? (FJO brand)People with OEM ecus report better idle and more HP can be made with a given size injector with a peak and hold driver.

3)How do the other ecu companies control low-z injectors? Why do they not need flyback protection?

4)Anybody using Honda or DSM OEM resistor boxes? These often wire to the + side of the injector, one wire in and 4 out. is it possible to use this with the TS diode also? The OEM resistor boxes mount easily,usually have a heat sink, and can be found cheaply.
