Default Virtual Dyno issues

So I can get the whole .msl to load, but its a good 20 minutes worth of driving. Is this accurate?

Then I tried to trim the .msl to one of my 4th gear pulls, as straight and level a road I could find, but it's giving me all kinds of errors. The first one was a E101, I fixed that by opening the .msl in excel and deleting the first row. But now I get a E106: A column named 'MAF_47160651.8942" already belongs to this DataTable. But I can load the whole .msl perfectly fine. What gives? It's showing I have more torque than horsepower...

Went out and logged only 4th gear 2600 -6700rpm. Still more torque than hp, is this right?

That's basically equal hp/tq, which is how a lot of turbo miatas dyno. You'll need to make improvements to help it breath better at high RPMs to get the HP a lot higher than the torque at a given constant boost level.

I have to leave the barn doors open so that probably creates a bit of extra drag at speed, may be why the HP is low compared to torque? I have a 2.5" dp to 3" exhaust, but no head work. Also this is a 1.6

It looks like you're boost is trailing off a little bit at higher RPMS which will hurt HP but not TQ. The barn doors will definitely affect virtual dyno and the effects show up more at higher speeds so that's going to hurt HP in relation to TQ as well.

I made 2 pulls headlights up vs headlights down a long time ago in a N/A miata and logged it. You can see what it does on virtual dyno.



Keep tuning that fuel map, you'll definitely find some power getting those AFRs into the 11's.
