just to throw it out there you could verify base ignition timing.
"10.Check that the actual ignition timing is at the standard value.
Standard value: Approximately 5° BTDC
NOTE: Ignition timing fluctuates about ± 7° Before Top Dead
Center, even under normal operating condition.
NOTE: It is automatically further advanced by about 5° to
10° Before Top Dead Center at higher altitudes."

yea that’s definitely something to check. I have seen the base timing off 5 degrees. Even if the base timing was off 7 degrees, that would give you 3 degrees at 26 psi, 4750 rpm. On pump gas that’s questionable. He also stated he was able to hit peak torque without encountering knock on pump fuel. This has never been the case in my experience. At 26 psi on pump fuel that motor is definitely knock limited. Something stinks around here.
@Biggiesacks very good point, it occurred to me that actual timing might be off. I'll try to share a video as the car is immensely powerful. I'll post the E85 table once it's done next month.
Looks good.
My map is slightly more aggressive on timing on 94 octane. not standard boost though.
what power are you running?
Thanks!! According to VD 275 atw now (don't know how accurate this is) @ 98 Octane so might be able to run more aggressive timing as you are doing. But this was mostly learning of how to smoothen the map
I am now getting into the progress of installing my MAC 3 port solenoid and upping my boost to 1.4 / 1.5 Bar, so hopefully up the power quite a bit. What boost and mods are you running? Are you happy to share your ignition map with me?

map smoothing is the most important part and you got that
Just got my rom off my car and my maps look nothing like anyone has. I don't hit boost cuz it knocks like crazy so I just kinda putt putt my car around. This is on E85
Or am I looking at the wrong stuff?

I see lots of blocks of 1 tryt o make it more progressive
