Idle speed adjustment not working ...
it's 2025 and I got stuck with some pre-Tephrav7 tune from my engine builder (I will get a v7 (again) from a reputable tuner later but I need to fix oil leaks/cooling issues first before getting on the dyno). This tune is fine for racing but street drivability sucks. on evoscan I noticed my AC-off "Target Idle RPM" is 450 (bad) and AC-on "Target Idle RPM" is 1200(good). So i'm pasting ISCV Control tables from 8858(jdm ix) to 8859(8859 ix)Please correct me if i'm wrong
