Hello, i spotted problem on my setup.
I just installed el.solenoid, which jack my throttle at 15%. And using config B with enabled partial fuel cut (idle treshold rised to 16%, idle PID zeroed, 2200/1100 overrun) which is switched by dual contact switch with the solenoid. ALS is switched independently on another switch(not activated in this situation).
I must open throttle over 15% to let solenoid put stopper in, first. Also its weak solenoid which is not release stopper itself, i must blip throttle again.
My problem is, when i switch to config B, everyting is ok, blib a throttle to jack it, partial fuel cut working, everything ok. But when i switch back to config A, it may logicaly idle RPM go high due still 15% jack. But it wasnt, engine runs very similar as with partial fuel cut - very rought,at similar rpm(but not the same). When i let solenoid release throttle, it stalls, because there is still some fuel cut/missfire even under 1100rpm and 0% tps.
I tested it with disconnected solenoid, just with few % throttle open by foot and realized, when during switch back to config A and im not at 0% tps, it missfiring ect.
Temporary solution is after throttle jack release to 0%(when switched to cfg A) quickly switch back to cfg B, let is settle on idle and then finally switch back to cfg A.
Also there is a progression of cutting/missfiring when i switch B->A according TPS percentage. When i do it with 15% it stalls immediately, when i do it with few % it has rought on idle.
Do you think its FW problem? Using older 1.2.17fw, its race car, dont need new features and i dont like changing things which worked fine..until today.
