Virtual Dyno sharing thread

It's a fun software to use, but I wanted to compare other peoples runs. This is on a relatively flat surface, anyone near the Bradenton/Sarasota, FL area can attest that being right on the coast = pretty flat land.

My mods on this run: JB4 G5, E50 blend, DCI, Methanol, 17.8psi tapering to 15psi @ redline

If you don't mind, could you paste your txt log file as well. Also, the weight of your car as used by virtual dyno, gear used in the pull and the gear ratio.

I'm curious as to how the results compare to what I would calculate.

I never thought about adding the weight of the driver as well. My results above are skewed then.

Why the drop in A/F ratio? was that intended?

I am running 80% meth so when meth is flowing on my particular car, I run a little on the rich side. I am in the process of manually adjusting my map to get my AFR target in the upper 11s under WOT. Right now they are in the low 11s/high 10s which is richer than necessary.

There is more of a taper (down to 16 psi) if I ran it to redline, but I shift around 6000-6200 so the taper isn't appearing like all that much. I am FBO+Meth and don't run this aggressive all the time, but the log was solid aside from being a little on the rich side.

Corn on the Cobb (~45% ethanol), compared to some other maps.

If you can leave black marks on a straight from the time you exit a corner till the time you brake for the next turn....... Then, you have enough horsepower.

Virtual Dyno's look great! I hate that my turbo's don't spool as fast as some of you other guys, DP's will definitely cure that for me.

Thats impossible since a MAC is technically all PC hardware running a different OS.

I attempted to log and post some 3rd gear runs but the virtual dyno was throwing some low numbers and the graphs were all over the place. Can someone look at my logs and see what I did wrong. I'm running vrsf dp's, dci, aa sport intercooler, cobb stage 2+fmic, and e30 blend. Car is a 2007 6at with fresh plugs and one coil recently replaced.
