MS3 1.50 Staged injection without sequential

Post by jamies »

Just playing with an MS3 on the bench,
This will be running a throttle body based injection setup with 8 injectors, 4 on the primarys and 4 on the secondarys.
For testing purposes i've set the staging to 35% TPS. 4 main injectors, 4 additional and planning to use them all on the ms3x outputs.
Ive setup staged injection but it appears it will only work correctly when sequential is set to on (semi seq). If i set sequential to off, only the 4 primary injectors fire above the preset TPS% even though pw2 and all seq pw 5-8 show pulsewidth in the gauge, the stim lights dont light up.
Soon as i set sequential to on, it appears tp operate as expected.

Also noted when i set gradual transition to on, with the same number of events for transition and reduction I also get PW spikes on the secondarys
