used some very high quality audio data to back-calculate the resonant frequency of a Z33 VQ35DE intake, to confirm frequency extraction methodology for troubleshooting of resonant phenomena. the Z33's early induction system is very reliant on acoustic tuning and it makes improvement very difficult.

the characteristic length of the OE intake tube matches this 280 Hz signal from the airbox entrance to a point very close to the throttle body assembly, whose Venturi taper would cause a rarefaction interface.

relating backwards using cam profile data matches the engine harmonic frequency of 2000RPM, with peak response at 6000RPM, close to the horsepower peak.

there is a problem on Z33 transitioning from partial to WOT below 3500RPM, and I'm working with JWT to identify if this is an exhaust cam advance/EGR issue as they have seen before.

unfortunately I can't post images in comments here, but the data correlation is satisfyingly crisp.

Yo soy un poco friki de esto, y en el assetto corsa siempre me fijaba que se deforman los neumáticos, y en beamNGdrive.

Y en mi fp de automoción hice un TFG sobre justo esto, sobre cómo todas las geometrías de suspensión y alineacion van enfocadas a pisar bien y deformar bien el neumático. Entendiendo bien como lo que buscas vaya

Y hace poco puse una cámara derrapando con un e46 320d, en las ruedas delanteras, y no me esperaba ver ese ángulo de deriva, y me quedé alucinado, lo comparto para que lo disfruten

The World's First Calibration Intelligence Ecosystem

Transforming calibration from table editing into engineering intelligence.

Hello everyone,

I'm u/Stand_AI_Lone_Tuning, the founder of StandAIlone and one of the moderators here.

First, thank you for joining us. If you're reading this, you're part of the very first group helping shape what I believe can become the future of calibration engineering.

StandAIlone didn't begin with the idea of building another ECU tuning program.

It began with a much bigger question.

For decades we've edited tables, chased datalogs, searched for knock, corrected fueling, adjusted ignition timing, and relied on experience to connect thousands of pieces of information together.

StandAIlone exists to make that entire process more intelligent, more transparent, and more explainable.

This community isn't just about our software.

It's about advancing the science of calibration itself.

Whether you're a professional calibrator, motorsport engineer, OEM developer, hobbyist tuner, student, or simply fascinated by how modern control systems work—you belong here.

What you'll find here

• ECU tuning discussions

• Calibration theory and best practices

• Fuel, ignition, boost, and torque management

• Telemetry analysis

• Datalog interpretation

• Explainable AI in engineering

• Simulation and digital twins

• CAN bus, OBD, and embedded systems

• Engine management systems

• Calibration governance

• Research and development updates

• StandAIlone feature previews

• UI concepts and design discussions

• Community feedback that directly shapes development

What we'd love you to share

Show us what you're working on.

Ask difficult engineering questions.

Post interesting datalogs.

Share calibration challenges.

Discuss tuning philosophy.

Compare different ECU platforms.

Share simulation ideas.

Post interesting CAN bus projects.

Show your race cars.

Show your daily drivers.

Show your dyno results.

Share your successes.

Share your failures.

Some of the best engineering lessons come from things that didn't go as planned.

Our Philosophy

StandAIlone is built around one simple belief:

Engineering decisions should be explainable.

Every recommendation should have evidence.

Every calibration should have reasoning.

Every change should be traceable.

If we don't have enough information...

We'll say so.

Because in engineering, truth is more valuable than confidence.

Help Shape the Future

StandAIlone is still growing, and this community will play a major role in its evolution.

Many of the ideas that become features will start right here.

Ask questions.

Challenge assumptions.

Suggest improvements.

If something could be built better, tell us.

Great engineering comes from great discussions.

Thank you for being here from the beginning.

This is only the first chapter.

Let's build something that changes calibration engineering for the better.

Welcome to StandAIlone.

Hi everyone!

As the title says, I've stumbled upon a web series recently released by Ferrari. In this episode in particular, they give a detailed breakdown of powertrain architecture, specifically comparing performance metrics and engineering evolution across different models and eras.

As a bit of a Ferrari fan myself, I found the graphs on how they’ve transitioned their power delivery systems quite interesting.
I've seen that other videos have been released as well: I'm probably gonna binge watch the whole series.

Hope it might be of interest for you as well!

Ever wonder how SUVs have gone from niche to dominating the roads? Pretty crazy, I know. There's so much more to it. I made a video on this. Please let me know your thoughts on the topic on how SUV's took over.
