Mod timeline
Every saved pull labeled with the mods on the car at the time, plotted across your build. See the WHP at the moment you installed each mod. Answers “did this mod actually do anything” with a chart, not a guess.
Free shows you what your car makes today. Pro is for people who want to track it over time.

What's coming next
In development for Pro
Coming next: Mod timeline, Cost per WHP, and Community baselines. No promised dates, but Pro buyers get all three as they ship. No re-buy.
Cost per WHP
Add what each mod cost. See which mods gave the biggest bang for the buck across your build. Useful when deciding the next mod or planning a budget.
Community baselines
Your number vs the median NC2 or ND2 from other users who opted into research data. Anonymous, aggregate only, no individual rows exposed. Lands once enough opted-in runs accumulate.
$19 one-time. No subscription. No ads. No account required to try it. No data sold.
DynoMiata Pro · $19 one-time
Built by a Miata owner, for Miata owners
I'm Danny. I daily a 2011 NC2. Every mod my friends and I installed on our NC Miatas left us with the same question. "It feels faster" is not a number.
Pro is the version I use on my own car. Free is where you'll start. Pro is where you stay once you've logged a few runs and want them to mean something next month, next season, next mod.
Danny, founderIn plain English
What each row means
The table is the reference. Here's what each new line means once you're using it on your car.
- Saved runs, forever Every analyzed run persists. Run from this morning, the morning after your last mod, the morning your buddy let you record his car. Today, six months ago, year and a half ago. All there.
- Overlay comparison Pick any two saved runs. They render on one chart, color-coded, with a numeric delta at peak and across the curve. The killer feature for "did this mod do anything."
- Clean PNG share No watermark on the export. Peak WHP and torque, your gen and trim, mileage, and mods. The version you actually want to post on the build thread.
The math
Same calculation in free and Pro
Pro doesn't add new math on top of Free. Both tiers use the same J1349-corrected calculation from your OBD log. What Pro adds is the workflow around the number: saved history, comparison overlays, unlimited uploads, clean exports.
Methodology →Works with any $25 OBD adapter
Any standards-compliant Bluetooth OBD-II adapter will do. We don't sell hardware. See the hardware page for adapter requirements, logging-app suggestions, and sample-rate guidance.

The promise
FIVE RULES I HOLD MYSELF TO
01 · Your runs
Saved forever in your account.
Every analysis you save lives in your dashboard. No subscription that strips them when it lapses. Delete your account and the cascade removes your runs, vehicles, and pending tokens within 30 days. Your data is yours either way.
02 · Open math
When the math changes, I post the change.
The road-load model is on the methodology page. When it changes, the change log posts the date and the diff. A saved run keeps the number it was computed with; re-upload the log to see it under the current model.
03 · No trackers
No ad pixels. No data resale.
No third-party scripts. No analytics that follow you off the site. Your data is not a product I resell.
04 · It's an estimate
Physics, not a measurement.
DynoMiata runs a road-load model over your CSV. Every share card carries the math so any forum reader can verify what produced the number.
05 · If I have to stop
You'll get plenty of warning and your data leaves with you.
I'm a solo founder. I can't honestly promise five years, or twelve months, or any other number that sounds reassuring. What I can promise is that if I have to stop building this, you'll know in advance and I'll publish a way to get every saved run out before the site goes dark.
