Nettlez Posted August 6, 2019 Report Share Posted August 6, 2019 So with the g4+ running in closed loop idle control there is an option for hold step. From the information in the help file I still don’t understand what this does? What does it do? What is an example of a hold mode? Also what do the values in the startup step table represent? Is it a percentage of base position table or a multiplier? Quote Link to comment Share on other sites More sharing options...
cj Posted August 6, 2019 Report Share Posted August 6, 2019 Hold step applies in the scenario where you are driving at above idle rpm (say 4k), then you put in the clutch and get off the gas - lets say you want to roll to a stop. As your revs drop, you want it to initally hold a few hundred RPM higher than idle so that it doesnt shoot staright past idle rpm and stall. Hold step is the amount of "extra" idle valve %/steps that is initally applied to catch the dropping revs, above what your idle table would normally command. EG your idle is normally 800rpm @ 50% idle control opening. hold step is 5%. when you get off the gas from high rpm, the idle valve will sit at 55% open, which means your rpm might be say 1000 for a couple seconds then it will drop gradually down to its normal 800 (50% valve opening) over a second or 2 - exact speed depends on various idle response parameters. Startup table is added to your base table to decide the amount of idle valve opening during startup and the first 3 seconds after startup (ie it fades out to normal idle numbers during those 3 seconds) Quote Link to comment Share on other sites More sharing options...
