Ken Dunkley Posted November 5, 2018 Report Share Posted November 5, 2018 Hi- with the Atom G4+ - When the ecu powers up but the engine is not cranking or running the isc solenoid ( bosch 3 wire ) stays closed . Is this right ? It only starts to open when cranking . Can i get it to open to its set point in the - idle base position table - before closed loop control takes effect ??

Adamw Posted November 5, 2018 Report Share Posted November 5, 2018 The aux output is off until the engine is cranking, it instantly jumps to 80% when cranking. For the Bosch 3 wire solenoid "off" is not actually closed - it defaults to a slightly open condition. I think most people would get pissed off if we made it click away when the engine wasnt turning.

Ken Dunkley Posted November 8, 2018 Author Report Share Posted November 8, 2018 Ok ta for that . Also is there any way to speed up its action . Even with all gains maxed it is painfully slow to open and react when say putting the car into gear ( Auto ) . You can watch it count open in tenths of a percent on the lap top . How fast do the Bosch solenoids react ? Is it the valve thats slow ? Or just the way the Link controls it ( Its set to 200HZ ) Are there faster reacting ones on the market that the Link can control faster ?

Adamw Posted November 8, 2018 Report Share Posted November 8, 2018 A solenoid will open instantly to match whatever DC is applied to it. For gear you should be using the park/neutral step so it instantly gets extra DC applied rather than waiting for CL to react. Quote Link to comment Share on other sites More sharing options...
Ken Dunkley Posted November 9, 2018 Author Report Share Posted November 9, 2018 Hi Adam - I dont seem to have that option on my idle control page . No park/neutral step . Is it on the Atom G4+ ? . I have not up dated the firmware in a while although it is mentioned in the link help file . I doubled checked my settings on the anti stall gain and i have increased those - From 15 to 25 . So ill try that too . Quote Link to comment Share on other sites More sharing options...
