Idle Issues with BTR NSR Cam

2 Attachment(s)

I'm running a BTR cam CAM 224/230 112+3 .500" Lift in a in a 03 5.3 dbw setup with a manual trans than I swapped into an old Pontiac. I'm struggling to get it to idle when I'm coming to a stop I have to keep feathering the throttle in hopes it will idle when I stop. Unfortunately I can't find any manual OS "12579405" in the repository to segment swap over. If anyone can give me a hand that would be great. Attached is my config and a log driving it down the road.

Thanks.

Curios. Do you really have to segment swap for a manual? Cant you just select manual?

Also have yoy tried adding airflow to the throttle follower or rolling idle?

No need to segment swap, you did it right with the manual in Transmission>General>general>Manual and PRNDL none. The Idle>rpm Base>setpoint should add 200-250 to your entire STOCK table. Return the rolling idle to 0. Idle> Airflow>Startup>Underspeed time give it 2 seconds. Base running airflow multiply current table by 1.60. Startup>Friction Airflow Initial> add 20% to table. I would make the Throttle cracker>Airflow> 400-1600rpm and between 0-32mph = 0 the Throttle Follower is the fine tuning, start by adding 1 g/s if it wants to stall after goosing the throttle and let off then add another 1 g/s making sure table units are g/s!
Spark>advance>Idle Spark Advance>In Park from 0.08-0.36 and 0-1200rom make 18*, from 1200-2000 same airmass interpolate between Horizontal and from 0,36-1.20 and between 0-2000rpm interpolate verticale bounds. This is a good start but may need add 2* 0-1200 range for better idle. COPY the in Park table to In Gear table.
The overspeed and underspeed are opposite what you want unless it was to make a very very lopey cam. Add 4* from 12.5rpm up to overspeed and add (-5) to the underspeed table from 12.5-up. If this tames it too much well go back and add 1/2 that.
PE you are going to need to change the Throttle>Hot and Cold tables, look at the Camaro or Vette for suggestions. Some people make the whole table 1 range and when doing the WOT MAF calibration you should but progressive TPS to engage PE is a lot more fun to drive. Zero the RPM and time delays or if you live in bad weather climate you may want to have some delay. Raising the Enable>MAP is an effective traction control. Torque management>Raise the Max torque rpm and max torque to 640lb-ft, ETC inj disable to 255 all modes. Spark retard vs torque reduction multiply by 0.30, some will 0 this out. Being a manual it won't effect the trans shift torque management to 0 out. There is probably some more but I hope this helps.
