TomB Posted June 17, 2021 Share Posted June 17, 2021 I've recently re-timed my cams (K series, Supersport, SLR/KV6 throttle bodies), and now its needs a little help at cold idle. I think I need to up may 150-200rpm when cold just to help it along a bit. When its warmed, idle is smooth around ~1000rpm, but cold its 850-950. Without making a mess of the map and settings, whats the easiest way to do this in the Emerald software? The IACV is disabled, so idle control is purely through injection/ ignition control. Ive got the manual, but there are few idle control settings, and Im not sur ewhat I need to look at. Thanks Link to comment Share on other sites More sharing options...
Dave Hardcastle Posted June 18, 2021 Share Posted June 18, 2021 TomB, you could always set the mechanical stop on the throttle cable. I appreciate this may make it tick over a little faster when hot as well, but it saves messing with the ECU. Link to comment Share on other sites More sharing options...
TomB Posted June 18, 2021 Author Share Posted June 18, 2021 I think I’ve cracked it - I’ve increased the max idle ignition trim value. This means the ecu can advance the ignition further to meet the selected idle speed in the map & temp compensation table. The maximum trim limit set was 15deg advance. Allowing up to trim to 25deg advance seems to have helped. Link to comment Share on other sites More sharing options...
oilyhands Posted June 18, 2021 Share Posted June 18, 2021 Add a little more air by opening the throttle using the idle adjustment screw, don't add too much or the hot idle will soar. This in conjunction with the ignition trim should give a pretty stable cold start idle.Oily Link to comment Share on other sites More sharing options...
