New Throttle cable from SN95, the travel is so much smooth. I am using a custom vice grip hold down.
Installed K&N Filter
As you can see my truck rails were leaking fuel from the end of the rails. I fixed this with a tube of JB Weld steel stick and just shoved the putty in there.
Also did my ghetto alignment.

I'm working on it! I have to get some kind of "tune" done.
You can see what I have tuned so far, mostly idle and very little load driving. My VE table is way off. Look at the trench I am building.
I am a noob at tuning but I should probably scale the entire original VE table by 30% then restart.

I am using their "autotune" method. While it is not live, I do not physically have to alter the VE table cell by cell.
The way they tune it, is data logging actual AFR and comparing to commanded AFR throughout the entire table, the software automatically does this for each cell. There will be a discrepancy (correction factor for each cell) - it was off such percent. Then you adjust the VE Table by that percent (copy/paste/multiply all cells at once). Flash it. Then go datalog rinse and repeat until correction factor is negligible
You can adjust the entire VE table this way if you hit all the cells during data logging. It can just get difficult to hit every cell while driving enough times for precise data. If you don't hit that cell it will not adjust it.
You also apply several filters to "clean" up the data so no incorrect data is applied such as remove data that was during decel, warmup, jerky/unstable throttle positions, etc.
Yes I did, however I have not gone into boost so the boost VE table has not been adjusted. Boost VE table is separate from Main VE Table, it goes from 105 KPA to 285 KPA.
I am running EFILIVE Custom Operating System 5 with a 3 bar sensor in Open Loop/Speed Density.
It just seems that my Factory/Default VE Table is way off for whatever reason. Nothing that more datalogging and copy/paste wont fix. I was just wondering, if there was a quicker way to ball park it by scaling the whole damn thing. I will post up my current graph/table so you can see how much one data log session about 25 minutes of city driving adjusts it.
I'll try to make a video on it.
