U01A safe tables include a cutout for the VVT resonance area around 5000 rpm

For those who are still studying 86 VVT, here's an update from the distant future of gen1.5 red intake ROMs: the intake tables are 3 rows taller, having been tuned specifically to reduce intake advance at load 0.0-1.0 x rpm 4700-5200. This is right about where we all hear that tinny VVT resonance on K-series tunes, and it doesn't silence that resonance - but it does limit how loud it gets compared to K tunes, and I figure if they went through the effort of resizing the table to put this in, there must be something worth considering in that. So, duly noted.


EDIT: Also! Some injection-specific changes in S10C/U01A that y'all may be interested in (the S10C XML and BIN elsewhere in the forum can be used to see these in RomRaider):



One value for Direct Injection Quantity Maximum has changed: RPM 2000, from 90 => 120 (increased by 30mL).


The GDI Pressure A/B tables have had nearly every value tweaked.


The Intake/Exhaust Duty Correction A/B/C/D tables have had most values tweaked.


The GDI Flow Rate (correction) table has had most values tweaked, with many cells being set to 1.000 (no correction).
