Illustrative drive display. Simulated readings, not a live connection.
A modern workspace for
a car with a little history.
Your engine readings, rolling trends, and vehicle health, together. See what’s changing before the details get lost.
Actual ZDash app.
Shown with simulator data.
A reading tells you what’s happening. The history helps you understand why. Keep both in one workspace.
Remember the work. Keep dates, mileage, service notes, and follow-up context with the vehicle they belong to.
Bring the evidence. Return to a recorded drive, review its statistics, compare what changed after a repair, and export the data.
Pick up where you left off. Keep the intermittent symptom, the investigation, and the eventual fix in the same ownership story.
See where it all goes. Track the part on order, the modification you saved for, and what the work actually cost.
Make room for the garage. Keep the details and history of each vehicle together, with core ownership records stored locally on your computer.
Your hunting idle. That hard-to-find part. The next thing to check. Work through it with an AI agent that has your car’s context.
Less starting from scratch.
More picking up the thread.
My 300ZX hunts at idle. Where do I start?
I can review the available fault codes, recent readings, and service notes together, then help you narrow down the next useful check.
Does the idle change when the engine is cold, warm, or both?
Your investigation is saved. Reply when you’ve checked.
Illustrative examples of the planned subscription. No live diagnosis or parts search is performed here.
The tools should, too.
ZDash started with a 1990 300ZX, and a familiar problem: live data in one tool, parts notes in another, receipts somewhere else. The most useful context was the part you had to remember.
So we’re building a place for all of it. Every drive, repair, question, and decision becomes part of the story. Built by an owner, for the long run.
Khalifeh Basiri, creator of ZDashKeep your ownership records without a cable. When you’re ready for live data, here’s what connects the car to the conversation.
An available USB port, or a matching USB-C adapter.
A USB or serial interface recognized as a COM port.
The gray Nissan CONSULT-I connector in a supported vehicle.
Check your model, model year, engine, and ECU against the final compatibility guide before purchasing. A standard OBD-II cable is not a substitute. Some interfaces need the maker’s USB driver.
No cable yet? Explore with the built-in simulator.
The desktop tools are yours for a one-time purchase. Add the AI agent when you want another set of eyes.

Explore the agentA few things to know about the app, the connection, and the launch.
ZDash is in active development. Purchase will open after the release build and vehicle compatibility guidance have been validated. Until then, ZDash is coming soon.
The first release is Windows-first and focused on selected classic Nissan and Infiniti vehicles. The exact vehicle and model-year compatibility list will be published before checkout opens.
Live vehicle features require a Nissan CONSULT-I USB or serial interface cable connected to the vehicle’s gray 14-pin CONSULT-I port. Windows must recognize the cable as a COM port, and some cables require a USB driver. A standard OBD-II cable is not a substitute. The built-in simulator works without vehicle hardware.
Core vehicle and ownership records are designed to stay locally on your computer. Any optional connected feature will be identified clearly so you can make an informed choice.
No. ZDash helps you capture evidence, see patterns, and bring better context to the next decision. It does not replace a qualified technician or professional diagnosis.
ZDash is planned to open at an introductory price of $39.99 USD one-time, then move to a regular price of $49.99 USD one-time. No payment is being collected while the product is coming soon.
The planned $9.99 USD monthly subscription adds vehicle-context investigations, parts research with fitment evidence, saved follow-up conversations, and draft cost, performance, or modification entries for your review. You approve record changes. AI guidance does not replace professional diagnosis, and a possible parts match is not a guarantee of fitment.
No. Live diagnostics, drive mode, saved sessions, and your core ownership tools are part of the desktop app. The AI agent is an optional subscription for help investigating questions, researching parts, and preparing records. Both the app and subscription are coming soon.
The planned AI subscription is an online feature. Your core desktop records and non-AI tools remain available without the AI plan. Live diagnostics still require a supported vehicle and cable.
