Tony Ouneissy1436215392 Posted September 6, 2022 Report Share Posted September 6, 2022 Using AtomX to control extra injectors on a LS engine. firing order 1-8-7-2-6-5-4-3 I use single point group and injection rate 1 and always connect the injectors like this : 1-6 output 1 8-5 output 2 7-4 output 3 2-3 output 4 Do you suggest a better setup?

Adamw Posted September 6, 2022 Report Share Posted September 6, 2022 Set to semi-sequential, Inj drive 1 to Cyl 1&7 Inj 2 to Cyl 2&8 Inj 3 to Cyl 3&5 Inj 4 to Cyl 4&6 It will then effectively be sequential/timed injection, 1 cyl of the pairs will get its fuel 90deg earlier than ideal, the other cyl will get it fuel 90deg later than ideal.

Adamw Posted September 6, 2022 Report Share Posted September 6, 2022 Yes, it would need 720 sync for semi sequential. Quote Link to comment Share on other sites More sharing options...
