Hi, I am making some step by step changes in my file for my 1.8T 150hp engine. Below will be my screenshot of my changes. Show me what you think for stage 1.
Load timing change methods: Full load request 160% @ 2,000RPM then very low decrease going down to 156% @ 3,000RPM, then decreasing more rapidly towards 136% @ 4,250RPM and down to 108% @ 6,000 RPM (will show graph below)
Timing change methods:
I changed in 0.25, 0.50, 0.75, and 1.00 (rarely) at some low load areas. I went from left to right, increasing about 0.50 most commonly then about 0.75 at higher RPMS between 4500-5500. I did higher increases +1.00 +1.25 at low load areas from 65% and lower. After I was done left to right, I went from up to bottom to make sure everything is smoothed out. (This was NOT a percentage change, I went there one by one to make sure everything is smooth and reasonable.)
So tell me your expert opinions, maybe I am utterly wrong. I hope I am getting this correct. Thanks! Screenshots below!

I just can tell you that in this way is very bad, why you changing the advance on low load and on the cruise area of the car ? i can recommand only on the 80% pedal and up ,

Ped% is not the correct variable for that axis. You're looking at load% not pedal.

Just the fact that you think changing cruise timing makes someone bad, makes yourself look bad. I am looking for expert feedback not salty feedback. Get off of this thread.

Your load seems pretty conservative in mid to high RPM, any reason for this?

Adding timing in whole range like that shows that you have no idea what you are doing. The only way to modify timing in non-knock limited area is on a dyno. Stick to changing only timing at the higher load cells, extend the map above 150 load.

And how would you do it on a dyno? Can it be done on a road?

Increase advance until you no longer make more power.

you really cant without a dyno. some say maf readings but this wont stand true when adjusting timing. fats? besides that a rolling road is the only way i know how

when you advance ignition angle, does injection period increase?

I worded that poorly.
I'm thinking if you no longer make any more power at a given advance/load, the load will start to increase and IDC will increase with it.
