janis. Posted July 25, 2016 Report Share Posted July 25, 2016 Need some help. Working on a setup staged injection on 5 cylinder engine. Injector drivers 7-8 will not come active. Injection mode is set Sequential/Staged. When change cylinders number 4 or 6 all drives are active. Quote Link to comment Share on other sites More sharing options...
Scott Posted July 26, 2016 Report Share Posted July 26, 2016 Hi Janis,I've done a basic 5 cylinder sequential/staged setup on my engine simulator and it seems to work. Chances are I have something configured differently from you. Can you post your base-map and a PCLog file of you running the engine under the conditions where you expect staged injection to be working. Alternatively you can email us the base-map and PCLog file to [email protected], If you email it to us please include a link to this forum thread.Scott.

Sutkale Posted August 3, 2020 Report Share Posted August 3, 2020 Lifting this up. How do you wire the injectors in 5 cyl engines to get 5 cyl staged injection? This ECU has 8 injectors drive, so 4+4 injectors is for sure doable. Quote Link to comment Share on other sites More sharing options...

Sutkale Posted August 4, 2020 Report Share Posted August 4, 2020 Thanks! 5 primary injectors clear but not quite how injectors 6-10 are wired. Injectors 6-7-8 to primary 7 and injectors 9-10 to primary 8? Quote Link to comment Share on other sites More sharing options...

Yes, the secondaries will be fired in group fire mode every 360deg. Injector drive 7 & 8 alternatively. So Inj7, then 180 deg later inj 8, 180 deg later inj 7 again etc. So how you pair them up doesnt matter. I would probably do 6&9 together and 7/8/10 together, this will spread the fuel pressure pulses in the fuel rail a little more evenly.
