injector timing

I have a btr stage 3 truck cam attached is the cam card. Do I need to adjust the injector timing for this cam? What should be the main focus for getting this to idle correct?

That's a fairly mild cam generally speaking, the LSA will give it some chop though.

The biggest things to fix are the airflow model, fueling must be on point so that idle corrections and timing corrections don't lead you in the wrong direction.

Before you do any major changes to the idle airflow or idle timing you really need to fix the MAF curve and VE table so that fueling is corrected for the new camshaft. Then you can go back and make your idle settings better if need be.

Bump the idle to 800-900 too. Also reduce the values in the under/over speed spark correction tables so that timing is not jumping all over the place on you. Some stock calibration allow for like +/- 20 degrees, cut that way down to like 5-8 degrees.

I got it running good fueling it's good but wants to die when I put it in gear. Once in gear idles Nd runs fine.

Disable LTIT's watch (log) STIT's and adjust your Base Running Airflow table as needed. Do a cold start and don't touch it until it's fully warmed up and watch the STIT's at each temperature increment in the table and adjust them in the airflow table, in the P/N line as you go through each one. In the same table, increase the airflow in the "Gear" line by 15% and flash it. The next cold start, fire it up and put it in gear again watching STIT's until it's warm and adjust your "gear" airflow values, re-enable the LTIT's and flash those changes.

you can try this table out if you want to. this is one i have used for a few mild cams in the past with decent luck.

I have my base airflow set idle in park is great doesn't try to die when I put into gear anymore. Problem now is when in gear it wants to take off and not decelerate after I let off throttle. thanks for everyone's help this is the part i can not figure out. attached is a short driving log

Check throttle cracker and follower tables
