StreetTunedAI LS/LT Tuning Portal

Know what your log supports, what to change, and what to check next.

You’ve got HP Tuners or EFI Live. You can record a log and open your tune. The hard part is figuring out what those channels mean together and which change you should make first.

Is the fueling off? Is that knock repeatable? Is the MAF curve wrong in one area? Did the fuel pressure drop during the pull? Can you work on cruise without a wideband? Is the combination ready for more power?

StreetTunedAI helps you work through those questions using your vehicle’s logged data.

Built for LS and LT owners, builders, and tuning shops, the portal brings log analysis, vehicle information, saved reports, follow-up questions, Startup Builder, and Tune Compare into one place.

$74.99 includes LS/LT portal access and your first 30 days of unlimited log reviews.

After your included month, choose $10/month for 10 reviews or $20/month for unlimited reviews. No separate AI subscription required.

What happens when you upload a log?

Upload the CSV exported from your supported logging software. StreetTunedAI checks the available channels, evaluates the recorded operating conditions, and builds a structured report.

The review covers the areas your file supports, including:

• Idle and part-throttle behavior
• Short-term and long-term fuel trims
• MAF behavior and supported airflow corrections
• Knock retard and spark observations
• WOT and Power Enrichment fueling
• Fuel-pressure behavior when the necessary channels are recorded
• Temperatures, throttle, load, and related diagnostic evidence
• Transmission observations where usable channels are available

The goal is a usable next step. That may be a supported calibration correction, a mechanical check, or a specific logging change needed to answer the question properly.

Real edits when the evidence supports them

StreetTunedAI can provide numeric correction guidance when the required data and calibration context are available.

That means identifying the supported table or correction path, the logged operating region, the amount of the correction, and what to verify afterward.

It also explains what should stay unchanged. You shouldn’t have to change five unrelated tables and then wonder which one helped or made things worse.

You make the final decision and apply the changes in your tuning software. StreetTunedAI does not flash your vehicle.

Power tuning is part of the workflow

Power Tune is for evaluating supported performance changes.

When the log contains trustworthy measured fueling, a valid loaded operating region, and the other evidence required for the requested edit, the analyzer can calculate fuel corrections and evaluate whether timing changes are supported.

Having zero logged knock is only part of that decision. Fueling, temperatures, fuel delivery, channel quality, and the actual calibration region also matter.

If fueling needs correction first, the report should move you through that correction and a verification log before adding timing.

Selecting Power does not manufacture missing evidence. It lets the system evaluate power changes the data can actually support.

You do not need a WOT pull for every review

A useful cruise log is still useful.

Missing WOT or wideband data should not stop supported idle, closed-loop cruise, fuel-trim, and drivability analysis. The report identifies which work can continue and which particular edits need more evidence.

A trustworthy wideband is required for WOT fueling correction. It is not a blanket requirement for every observation or every closed-loop correction.

What the AI actually does

StreetTunedAI’s core is a deterministic analyzer: programmed checks, calculations, channel validation, and evidence requirements.

The AI helps explain those findings and answer follow-up questions in plain language. The system is designed to check recommendations against its evidence and safety rules.

That does not make software incapable of mistakes. It gives the review a defined process, and you remain in control of the tune.

More than a single report

Your portal includes:

• Saved vehicles and build information to keep each combination organized.
• Saved reports and downloadable PDFs so you can review previous findings.
• Follow-up log reviews to check what changed after an adjustment.
• AI Tuning Assistant for questions about your combination, findings, and next steps.
• Downloadable channel files to help set up supported HP Tuners logging.
• Startup Builder for initial setup guidance on a new combination using the information you provide.
• Tune Compare to review differences between supported calibration exports.
• Direct support from Bryan through portal support tickets.

What you need

An LS/LT vehicle or project, supported HP Tuners or EFI Live logging equipment, an exported CSV, and internet access.

For Startup Builder and exact table-level guidance, provide the relevant hardware details and calibration information. The system cannot inspect the vehicle or confirm parts you have not identified.
