You should use a single driver for each injector 3. You could use either an IGBT or a MOSFET as a injector driver, just make certain it has a high enough rating to handle the load. Aleast a couple hundred volts with a internal diode for the fly-back voltage and about 10 amp rating. Capt. Quirk Manfactures use sequential injection for the best cylinder to cylinder balance and to keep feedgas emissions to a minimum (better fuel prep and good cylinder-to-cylinder distribution). After all these years of working on engines I do prefer Fuel Injection, because it works so damn good. I think you would need to work on a A/F distribution problem with a carb system for about 6 months to appreciate how good an EFI system really is. ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=4&m=192262#m194601 Need assistance?
