Map smooth enough?

Can anyone give some insight into if i need to continue to smooth the map or if it is ok, I am within a 5% error on the log. I havent gotten the truck into higher RPM yet, I have only been able to work on it up to 2000 rpm. I think i need to add some timing advance over 2000 rpm since it seems a little sluggish up there.

Click the smooth selection icon twice, that will help level off the bumps in there. Then carry on what you are doing.

Are you using trims or a wideband for that data?

its best not to smooth till after you have more defined map. when you have limited plot hits like that, what happens is when you hit the smooth button, it just pulls it back level with the surrounding area, essentially taking back away what you just changed

also a note that i see, what are your mods, i typically am not having to add that much in those areas. what is your fuel pressure?, i wonder if you have a bad pump, that would explain being sluggish up top too

I am using an aem wideband logging through the egr. I did realize today though that I had the stft still on and wasn?t set to 284 so I am gonna have to work at it this weekend with some longer drives.

I am running a quantum 340lph fuel pump with a Holley fpr. My fuel pressure is set to 60 at the rail. The only other problem I am having is hard starting sometimes from the engine flooding. I took some multiplier out of the cranking stage and that helped a lot and added 2 degrees timing to the cranking timing table. I actually figured out why it was so choppy, I still had the stft set at stock temp instead of 284 so it was using the stft. I turned that off and grabbed a quick 5 minute drive and it was about 6-9% rich and a whole lot smoother on its own from that. Also it revs out to about 4K just fine,(I couldn?t get past that since it would shift and over 4K in 4th gear is going way to fast for not being in Mexico! Mods are it?s a 6.0 lq9 with 799 heads, tbss intake, warr throttle body, and btr truck stage 2 cam.

you can command it to hold a specific gear in the scanner!!!!!
