Title: Virtual Dyno Numbers Comparison
Post by: FiveLeeter918 on August 01, 2017, 09:30:27 AM
For those of you that use Virtual Dyno to view your logs as dynographs, post em up and let's compare!

Here's mine, 18 psi of boost and 20 degrees of spark advance, but getting some knock up top that's knocking me back down.

4th gear pull...

How much KR are you seeing up top? May need to add enrichment since your blend isn't as stout.

I get a little false knock right at 6000 but otherwise nothing. We were getting some before and dropped fuel from 0.84 to 0.82 and cleared it up. Not adding any right now but not taking any away either.

Added a little more boost down low and gained 50tq down low, but peak numbers aren't coming up much.

Currently commanding 20 psi (seeing 18-19 mostly) and 20 degrees of spark. No knock until the car shifts and it gets a little false.

What PID are you using for boost?
Title: Re: Virtual Dyno Numbers Comparison
Post by: FiveLeeter918 on August 02, 2017, 11:13:49 AM
"tip prs boost kpa" and "Boost in PSI"

Have you looked at your chart uncorrected?

Rev 39

geeze, what do you mean uncorrected? This is STD not SAE correction if that's what you meant.

So you got these numbers with 15.5 psi and 26 degrees of spark advance? Mind sharing a datalog?

I think I misspoke....I meant with no smoothing...

Log attached

Turning off smoothing it goes erratic.

Same log data but I added weight because I think my shipping manifest was higher than Mike's posted figures.

When I weighed the 13 with me in it and a full tank it was just over 4700 so IDK but weight seems to impact the numbers

why is your measured AFR stoich until after 4500 rpm?

DI E85 doesn't need the enrichment straight gas requires.

BTW, the knock DMR on that log reverses knock so a + number is adding.

so that's full e85 or the e45 in your signature?

E45...

Well this is about as good as we're gonna get for now I think with these IATs... Gonna back the boost down and add some more timing :)
Title: Re: Virtual Dyno Numbers Comparison
Post by: FiveLeeter918 on August 02, 2017, 03:59:55 PM
Take one commanding 15 psi and 26 degrees of timing. Numbers seem really low compared to the above... thoughts?
Title: Re: Virtual Dyno Numbers Comparison
Post by: FoMoCoSHO on August 02, 2017, 06:37:01 PM
Dropping down boost should have a positive effect on iat2 and coolant temps. You've got to be inducing a ton of heat into the system at 20 psi. Your rail will thank you as well.

Rev 2. HP is now higher than the high boost option, but still largely different from the high boost torque numbers.

I would throw HP out and focus on torque and carrying it as long as possible. Your ECM doesn't care about horsepower.

Is spark the same on both?

Fueling is the same. High boost knocked after 20, low boost was seeing 26 with knock up top.

I've got poopy resolution which Brad suspects are from DMR's.

I wonder if that's why my numbers are so inconsistent.
