Hey guys, so I finally made the jump to SD and right away I can tell I am going to have a lot of learning to do. I dialed in idle pretty good I would say, but I am completely stumped on cruising. I'm not sure what I am doing wrong but I posted a cruise log for anyone willing to help. What I do notice is that when I use SD VE adjust (SDRatio) vs SD VE adjust (CombinedFT) I get completely different suggestions for each. Most people I see use combinedFT and that gives me some very random suggestion and the upper left spots of my VE Table which end up looking like bad "hot spots" on my table. I'm having a hard time grasping what to do here.
Anyway, I added a cruise log from last night titled "sd help 2" and then one from today after some adjustments titled "cruise"
Thank you in advance
1). No boost, vac, or exhaust leaks.
No leaks
2). Verify mechanical timing.
Good
3). Verify base timing
Good to go, 5*
4). Ignition system
Good
5). Motor health
Good, Healthy compression. I believe over 170 psi on all 4.
6). Basic throttle body adjustments.
Good
7). Compression ratio
8.5:1 (stock)
8). Wiring and sensors
Good
9). No DTC/CEL codes
Random misfire code here and there and I am not sure why. Car runs fine though.
10). Electrical system
Battery 12.5v with car off, 13.xv with car running
11). Base fuel pressure and injector values
2150 cc high impedance injectors, 43.5psi base fuel pressure
12). Properly calibrated and configured wideband sensor
Good to go
13). Type of fuel
91 Pump Gas
14). ECMlink how-to videos
Watched. I even watched the videos on youtube of SD tuning for WOT 1,2, and 3.
