The work

What rolls in, rolls out better.

Petrol or diesel, import or domestic, daily or weekend car. Bring it to Los.

  1. ECU tuning

    A calibration built from your stock read for your hardware and your fuel. Fuel, spark and boost dialled in, checksums repaired, the stock file archived.

    • Stage 1 / Stage 2
    • Custom & E85
    • Revisions from your logs

  2. Diagnostics

    Check-engine lights, limp mode, derates, the weird intermittent stuff. We plug in, read the codes and the live data, and find the actual cause.

    • Codes & live data
    • Data logging
    • Module programming

  3. Performance builds

    Turbo and supercharger builds, intake, exhaust, cooling and suspension, planned as one build and tuned so the parts actually show up at the wheels.

    • Forced induction
    • Exhaust & intake
    • Suspension

  4. Parts & install

    Not sure what to buy? We'll spec the supporting parts for the power you're after, then fit them and map them into the tune.

    • Supporting mods
    • Fitment
    • Install + tune together

  5. Remote tuning

    Out of town? Our tuner can work on your car through your cable over the RC Flash relay. You flash, you log, we revise.

    • Your cable or ours
    • Flash & log anywhere
    • Same file standard

  6. The hard ones

    The controller nobody else will touch. If it needs an unlock, a checksum or a feature the factory never shipped, RC Flash's stack is built for it.

    • Unlocks
    • Checksums
    • Custom features

Coverage includes:

  • VW / Audi
  • Subaru
  • Ford
  • GM
  • Mercedes
  • Hyundai / Kia
  • Toyota
  • BMW
  • Petrol
  • Diesel

Don't see yours? Call or text Los with the year, make and model.

Emissions stay in

No deletes. Ever.

We don't sell deletes or defeat devices. We make cars stronger and more efficient with the emissions systems in place, and every file change is versioned on RC Flash with a full diff and a byte-exact revert.

Questions

Straight answers.

How do I get started?

Call or text Los at (737) 747-2233, or email hello@guerrilla.sh. Tell him the year, make, model and what you want from the car.

What's the connection to RC Flash?

Guerrilla Automotive is RC Flash's Austin branch. Los does the hands-on work here; tunes, projects, files and payments run on the RC Flash platform at app.rcflash.io.

Is a tune safe for a daily driver?

That's most of what we do. Safety strategies stay in and we calibrate for the long run, not a number on a graph.

Do I need my own flashing tool?

No. Bring the car to Los, or for remote work use your cable or ours over the RC Flash relay. Tunes are delivered as a plain binary.

My car isn't on your list.

Ask anyway. Supporting a new controller is engineering time on RC Flash's own stack, not a request to a tool vendor.

Do you do emissions deletes?

No. Not on road vehicles and not on anything else. It isn't the business.

Hit up Los.
