As usual the dsmtuner's geniuses come out of the woodwork. Here's to not listening to what you're saying. :cheers:

Speaking of yourself I see

Actually the mitsubishi knock system is very good, it's very responsive and fairly conservative. I used to run a 1g with a 14b at 20 psi with a sidemount and regularly saw max knock counts, bought it with 100k sold it with 135k still running strong. This 2g has a 6 bolt block I got out of the junkyard, stock pistons stock rods, honed re-ringed and new bearings. Put 30k on it with the big 16g seeing 5+ degrees in 4th/5th regularly. Pistons looked brand new (except for carbon).

And no you're wrong about the way a knock sensor detects knock. The only thing that will affect the way it "hears" knock is if you change the characteristics of the block itself, IE going with an aftermarket block. Going with solid cams or pistons with larger clearances CAN affect knock, but it will not mask knock it's the opposite, they generate noise which can be in the frequency range of the filters in the knock system and you will get false knock.

But you won't listen to any of this, keep tuning the way you tune and I'll tune the way I tune, motor was built at 150k, car has 185k with 91 octane in it 99% of the time.

@biglady112 Thoughts?

49178-01420 is a standard Big 16G, not an Evo III.

Still a good turbo, but these tend to top out around 38 lb/min so 34/35 is acceptable to be honest.

Do you think a max of 33 lb/min on my car at elevation is right? B16g, E85, stock 7 bolt/automatic trans. Full exhaust, big FMIC, lightly ported exhaust manifold, lightly ported turbine housing.

I haven't changed any mass air flow comp settings in link, but it doesn't seem to be off much (all stock sensors/MAF). It says 22-23 psi boostest at 5000-5500 RPM, when my mechanical gauge says a max of 24.

I'm on E85, with a peak timing at 6500RPM of 21 degrees, about 24 psi on a cool night. Very little difference in airflow from 21-24 PSI.

I guess I shouldn't be too concerned with it, I have most of the parts to move forward with the HY35 install. I just hate leaving power on the table or unsure why a car doesn't run as well as it should.

As requested here's my max octane map, my min is like 3-4 degrees less

That looks about right. On 21 PSI, my timing is a little more aggressive on 91 octane, but I have less airflow. I guess the elevation is killing me??

What AFR do you like on that fuel? Anything leaner than 10.8ish would produce knock for me. I try to tune to never see the check engine light (2 degrees pulled).

OP, is your altitude actually sea level?
Your boost est is not correct if you're @ 24-25psi. Your log shows 21psi at 5.5k taper down to 18psi by 6.4k rpm (time stamp 545.346sec)
Coolant temp, could be a little better, but not a big deal at those temps.

You have a DTC code 1400 MDP sensor malfunction

Do you have a wideband?
Why didn't you log MAFRaw & MAFcomp?
