NOOB - Help/base map needed for RB20 Skyline GTST with a Holset HY35 440s and Z32

Hi there,

firstly: I have no clue about tuning engines, adjusting maps and stuff and am therefore looking for a base map I could possibly use for my setup:

HCR32 RB20DET engine (no engine swap)
Holset HY35 Turbo
440 GTR injectors - all tested and working fine
Z32 afm
Walbro 255
External Tial 38mm wastegate 0,7bar spring
Im looking to run the engine at 1bar perspectiveley

After a good year of doing the turbo setup and everything that comes with it the car actually fired right up but was running massively lean. Before first start I changed the injector sizes and afm to the new specs. We did not have it running for too long. My buddy adjusted the fuel map to get the AFRs down to 16-18 (was 28 at first). Hes familiar with tuning VW VR6 Turbos engines via EMU and Link management but not familiar with Nistune unfortuneately. Anyways - we maxed out the fuel map but the AFRs still werent in a range you could use the car in.

I was hoping for someone who could help me out with a base map I could use / start from... or any other help to get this thing running.

Huge thanks in advance!

George

I don't provide base maps, but for the above, you would be best just starting off from factory and resizing MAF to Z32, and then injectors (untick TIM) from stock to 440CC and then aftewards adjust mixtures to get cruise at 14.7:1 (no trim)
