N146 map for T4 2.5 TDI AJT

Postby Subislav » Mon Sep 21, 2026 2:12 pm

Hello,

I am doing the 88hp AJT engine with upgraded .216 nozzles and hybrid K14 turbo. I'm struggling with N146 map.
For base tune i just dropped the ACV (factory .205 nozzles) and it runs quite good but still has some smoke and diesel smell issues. Do you have and want to share a good N146 map for AJT 11mm pump and .216 nozzles? I can't just put the 2.5TDI T4 150hp map because the pump from 150hp has different characteristic. And i've tried modifying the mg/str axis by lowering the values by 11%, but it was running worse than stock ACV tables. Can you help me with tables or good advice?

Cheers!
