Tuning software for professional Tuners and Users. On the website you manage Users, cars, credits and tune files. The Windows app connects to the car through a J2534 adapter to identify it, read its modules, flash tunes and run diagnostics.

Click Sign in, then Create Account. Enter your email and a password and click Send Verification Code. Type the 6-digit code from your email (it expires in 10 minutes, so check spam), click Verify & Create Account and choose your account type. You can't sign up inside the Windows app.

Choose Continue as Tuner if you run a tuning business: you buy credits, unlock cars, upload tunes and manage Users. Choose Continue as User if a Tuner looks after your car: you read it and flash the tunes your Tuner shares, but you can't download tune files or buy credits.

Users can upgrade to Tuner in web Settings. Upgrading ends the previous tuner relationship and keeps the account, credits and history. Contact Support to change from Tuner to User. The Windows app won't sign you in until you've chosen.

Sign in on your Windows PC, open Desktop App and click Download Installer. The app runs on Windows PCs only; the website works on phones and tablets.

The first time you sign in on a new PC, enter the one-time code we email you and click Confirm Desktop. An account can trust up to 5 PCs.

The years shown for each module are a sample range, not a promise for a specific car. In the Windows app, connect your adapter, turn the ignition on with the engine off and click Read ID. It reads the VIN and identifies the car's CPC, ECU and TCU. Reading is free.

STRATA FLASHER (USB-C) and STRATA FLASHER WIFI; Tactrix OpenPort 2.0; Autel MaxiFlash Bluetooth, Elite/Pro, JVCI, JVCI+, LVCI, VCI and VCMI2; CarDAQ-Plus 3 and CarDAQ-Plus 2; MongoosePro Mercedes; Mongoose-Plus J2534; Bosch Mastertech VCI; Snap-on Pass Thru Pro IV; and Scanmatik SM3 USB.

Install the adapter's 32-bit J2534 driver; the Strata Tuning app is 32-bit. The Strata Tuning installer also installs the STRATA adapter driver (Windows asks for permission once).

A Windows PC with the app, a supported adapter with its 32-bit J2534 driver, a high-current programming power supply, a stable internet connection, and a car whose VIN a tuner has unlocked.

Connect a high-current programming power supply and keep it connected for the whole flash.

For CPC-NG, the engine ECUs, VGS-NAG3 and VGS4-NAG2, the Flash button stays off until the adapter reads 12.0 V or more in the last few seconds. GS_AMG_DCT needs three readings above 11.0 V with the engine off. They're taken when you read the TCU, so read it again after connecting the power supply, and they're checked again just before erasing. TCM7FDCT needs above 11.0 V with the engine off. It's checked when the flash starts and again just before erasing; at 11.0 V or lower it stops before anything is erased.

Yes, a stable connection from start to finish. If it drops before anything is written, the flash stops and nothing is written. If it drops after writing starts, keep everything connected and follow the screen: depending on the module, the write finishes and its Flash record uploads by itself once you're back online, or the flash stops and you read the module again and flash again. Also leave Windows set to Set time automatically.

Only Tuner accounts buy credits, on the website Dashboard with Buy Credits. 100 credits unlock one car (one VIN) for one account, yours or one linked User's, covering every supported module on it and repeat flashes.

Packs (USD): 100 credits $100, 600 credits $500, 1,300 credits $1,000 and 4,500 credits $3,000. Your Dashboard shows whether tax is added.

Yes. Read ID and Diagnostics (Scan Modules and Clear DTCs) never use credits and need no unlock. Manual fault-code scan and clear isn't available for GS_AMG_DCT or TCM7FDCT.

Once any credits from a pack have unlocked a car, the whole pack is non-refundable. Restoring access to the same car for the same User later is free.

Each User creates their own account and chooses Continue as User. In Users & Access, click Add User and enter the email they signed up with; no invitation is sent. They connect their car and click Read ID in the Windows app. The car then appears under their email, and you unlock it with Unlock vehicle · 100 credits. A User can be linked to one Tuner at a time.

Users looking for a Tuner also post in Tune Requests. Reply with an estimate; when a User chooses you, they're linked to you right away.

On the website open Files, pick the User under Assigned Users, then their car's unlocked module. Click Upload File, choose the .bin and upload it. The tune is tied to that User, VIN and module, and they flash it from the Windows app. Each module has its own size limit, shown in the upload panel.

No. Users flash the tunes you share with them in the Windows app, but they can't download or edit them. Tune files are stored encrypted.

Create an account and choose Continue as User. Then open Find my Tuner, describe your car and what you want, and post it: tuners reply privately, and you're linked to the one you choose right away. Already know a tuner (see the Tuner Directory with View all tuners)? Give them the email you signed up with and they add you.

Then install the Windows app, connect to your car and click Read ID. Your tuner unlocks the car and shares your tune, and you flash it from the app.

Users open Find my Tuner, describe the car and what they want, and post it. Tuners see the request with a name like User 4821 and a city, never the User's email, and reply in a private conversation, often with an estimate. The User picks one with Choose This Tuner and is linked to that Tuner right away.

Up to 3 requests can be open at once, each for 30 days. Tuners find them under Tune Requests. A User's current Tuner doesn't see their requests.

A User can have one Tuner at a time. To switch, post a request in Find my Tuner and choose the new Tuner from their reply: the old link ends and the new one starts in one step. Leaving in Settings › Connected Tuner also ends the link. Access doesn't transfer automatically: the new Tuner unlocks the car again.

Sign in with your Tuner account and open Join Our Network. Fill in your business name, contact email, city, country and at least one service, tick both consent boxes and click Submit for Review. Your listing appears after Strata Tuning approves it; your contact name and email stay private.

The module only opens for the car you just read with Read ID, once its VIN is unlocked. Before writing, the app checks that the selected tune is approved for that exact module, that the battery passes the module's check, and that Strata Tuning approves the flash online. A CPC is read again automatically right before writing.

If a check fails, the flash doesn't start and nothing is written.

Follow the Before You Flash list on the Ready to Flash screen. Battery Support: a charger or power supply connected for the whole flash. Cable Check: OBD and J2534 cables secured. Vehicle Prep: ignition on, engine off, accessories off and doors closed. During the Flash: don't unplug the interface or power-cycle the car.

Leave the power supply and adapter connected and don't power-cycle the car. The app tells you what happened and what to do next: read the module again, then flash again. A failed or unfinished flash never blocks the car, on this or any other PC, and nobody has to approve or release it. A flash whose write finished while its Flash record is still uploading is complete. Only if the module can't be read at all, keep it powered and contact 24/7 Support.

Strata Tuning's own updates and pop-ups can't. During a flash the app locks its pages and the Close button, stops the PC going to sleep while idle, and holds its update prompts and pop-ups until the flash finishes. Strata Tuning maintenance pauses only new work.

Windows itself can still restart for its updates, so pause Windows Update before you start, and don't close a laptop lid, sleep or shut down the PC until the flash finishes.

Open Help & 24/7 Support in the left menu of either app for guides for the screen you're on. To ask Strata Tuning, use its 24/7 Support tab: choose the app and issue type, describe the problem and click Submit Request. Replies show under My Requests in both apps.
