TOMMYFD Posted October 25, 2022 Report Share Posted October 25, 2022 Changed my injectors have all the data given by injector dynamics my settings are all good but my idle jumps up and down from 700-2000 rpm and goes lean. The only way to have a steady rpm is to have extreme numbers in my ve table over 65% and has a steady 2000rpm with good afr. What can I do to get my iddle back. Any help please Quote Link to comment Share on other sites More sharing options...

Adamw Posted October 26, 2022 Report Share Posted October 26, 2022 Your VE around the idle area is only around 30-40% in that map? This is not high - typical would be more like 50-60%. For modelled mode the IAT trim should be turned off and the charge temp approximation needs some realistic numbers in there. Use the example table in the help file.

TOMMYFD Posted October 26, 2022 Author Report Share Posted October 26, 2022 The ve tables on this map are set back to normal when the car doesnt idle. To make it idle it has to go over 65% Quote Link to comment Share on other sites More sharing options...
TOMMYFD Posted October 26, 2022 Author Report Share Posted October 26, 2022 Does the iat and charge temp approximation affect idle so much? Because with the old injectors it didnt. Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 26, 2022 Report Share Posted October 26, 2022 I suspect they wont make a lot of difference. Turning off the IAT trim would add some fuel, but putting some realistic numbers in the charge temp table will pull some fuel out - so they will likely almost cancel each other out. More likely deadtime related if the VE is only exaggerated at idle and normal at higher pulsewidths. Quote Link to comment Share on other sites More sharing options...
TOMMYFD Posted October 27, 2022 Author Report Share Posted October 27, 2022 ok tuned my map a bit now everything looks ok but I have no injector duty cycle for secondaries why dont they activate? Quote Link to comment Share on other sites More sharing options...
Adamw Posted October 27, 2022 Report Share Posted October 27, 2022 Will need to see a log. Most likely havent met the Sec PW lockout. Quote Link to comment Share on other sites More sharing options...
