Lean in boost load scale issue?

[akurtzer57]

So running dsm 450cc set k constant to 141 and latency about 770 car don't start. If I use the injector resize tool then change maf to z32 it Changes my k to around 300 idles and cruises great. But no matter what I do in boost leans out really bad. Load scale goes up into 170 tried readjusting so can run far right side of fuel map in boost and car runs like complete crap. My last tune before I had the 450cc my load only went to 70 ish and ran great. Never had this problem.

Heres my tune

Z32 MAF K = 345 to 575
Injectors (185CC > 450CC) K = 575 to 236

Crank enrich tables were not adjusted.

Would advise leaving the load (stock) at 102 until you find out what your maximum TP is reaching. Having the scales too far out, it will never use the full fuel map

Using a VG30E ECU means its tuned currently for a NA. You probably will need to pull a heap of timing out on boost and richen up your fuel map (look at Z32 VG30DETT fuel maps for an idea of what these look like to start with). Second part of why it would be leaning out

Attached is what I did so far. Left scalers as they were and K at 236 for now. You may want to put K back to where you had it if running fine there, then see how it runs up after fixing up the fuel to reach proper mixtures on boost. Pull out at least 5 degrees or more timing in that area also

Ill give it a try. I did try running a map leaving load scales stock but couldn't keep car running. I took out over 10 degrees timing so safe there.
