Zchris Posted August 13, 2018 Report Share Posted August 13, 2018 I have a new Atom all wired in. Went thru setting up and it starts great. It is a 4 cyl 2.4 Duratec with 14:1 compression, big overlap cams, IR throttle bodies and SIR. The closed Lambda is off. I have an Innovate LC1 wired into AN Volt 3. Function Lambda 1, Calibration Innovate LC1, Error Low = 0.00, Error high = 5.00. With the Error Value set to 1.00 Lambda it will start fine and after a few seconds surge up in rpm only to stall. When I increase that Lambda value to 10 it will still surge but not stall out. It just idles for several seconds and surges repeatedly. What the heck am I doing wrong.

Simon Posted August 14, 2018 Report Share Posted August 14, 2018 Leave the lambda error at 1. Assuming all lambda functions are turned off it should have no effect. Increase your master fuel number and see if it will hold an idle. Being on ITBs you will need to change the main fuel table to TPS. Quote Link to comment Share on other sites More sharing options...
whittlebeast Posted August 14, 2018 Report Share Posted August 14, 2018 My next few videos on my youtube channel are designed to help people deal with idle control. Quote Link to comment Share on other sites More sharing options...
Zchris Posted August 14, 2018 Author Report Share Posted August 14, 2018 Simon, its already on TPS. It has no idle control stepper motor. What else drives Lambda control. Does the "Fuel Main" "Open Loop Lambda Table" being "ON" drive the fuel map? Thanks Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 14, 2018 Report Share Posted August 14, 2018 If CLL is turned off then the analog error settings or reading from the sensor will have no influence on calculated pulsewidth. The open loop lambda table is part of the fuel calculation and is basically a multiplier. For instance if you had a 1.0 in that table originally and changed that to 0.9, the ecu would add 10% more fuel. Quote Link to comment Share on other sites More sharing options...
