About Midgard Industries

Midgard Industries provides LS swap ECU programming, startup and base calibrations, HP Tuners services, Holley EFI tuning, ACES EFI tuning, remote tuning support, and related automotive calibration services.

Services may be provided locally in Longview, Texas, through remote communication, through tune-file delivery, or through mail-in ECU programming.

The exact scope, price, turnaround time, and included revisions depend on the package purchased or written quote accepted by the customer.

Orders and Service Acceptance

Submitting an order or payment does not guarantee that a particular ECU, vehicle, engine combination, or tuning request is compatible with the selected service.

Midgard Industries may review the information supplied before accepting or beginning an order. We may request additional information, photographs, part numbers, tune files, data logs, or other documentation.

We may refuse or cancel an order when:

The ECU or vehicle is not supported
Required build information is missing
The requested service cannot be performed safely or lawfully
The selected package does not match the combination
The ECU appears damaged, modified, locked, or otherwise unsuitable
The customer provides inaccurate or conflicting information
The order presents an unreasonable risk of damage or improper operation

If we cancel an order before programming begins, amounts paid for unperformed services will be refunded, less any nonrefundable payment-processing charges where permitted by law.

Pricing and Payment

Prices displayed on the website are in U.S. dollars and may change without notice.

The price shown at checkout applies only to the service package selected. Additional work may require a separate charge, including:

Unsupported or unusual operating systems
Segment swaps
Operating-system changes
Locked or previously modified ECUs
Additional tune revisions
Extensive diagnostic work
Replacement hardware
Expedited service
Additional return shipping
Changes requested after programming has begun

Payment may be processed through PayPal, Stripe, or another provider disclosed at checkout.

Midgard Industries does not directly store full payment-card numbers, banking credentials, or PayPal login information.

Payment must be completed before programming begins unless otherwise agreed in writing.

Customer-Supplied Information

The customer is responsible for providing complete and accurate information, including:

Engine year and displacement
ECU or PCM type and service number
Drive-by-cable or drive-by-wire configuration
Transmission type
Camshaft specifications
Injector part number and flow information
MAF and MAP sensor information
Fuel-system configuration
Fuel type
Tire size and rear gear ratio
Fan settings
Vehicle modifications
Current symptoms and intended use

Midgard Industries relies on the information supplied by the customer.

We are not responsible for poor operation, engine damage, transmission damage, ECU damage, or other losses caused by incorrect, incomplete, outdated, or misleading build information.

The customer must notify us before programming if any part of the combination changes.

Customer-Supplied ECU Condition

The customer represents that they own the ECU or have authorization from the owner to have it programmed.

Customer-supplied ECUs are used electronic components and may contain hidden defects, corrosion, damaged circuits, prior programming errors, locked calibrations, failed memory, damaged connectors, or other problems that are not visible before service begins.

Midgard Industries may photograph, inspect, identify, connect, read, erase, reprogram, bench-test, or otherwise handle the ECU as reasonably necessary to perform the purchased service.

Programming does not repair defective ECU hardware.

Midgard Industries does not guarantee that a customer-supplied ECU is functional before or after programming when failure results from an existing hardware defect, prior damage, corrosion, improper wiring, incorrect power or ground, reversed polarity, voltage spikes, water intrusion, or another condition outside our control.

Startup and Base-Tune Limitations

A startup or base calibration is intended to provide a reasonable starting point for the combination described by the customer.

It is not automatically a complete dyno tune, road tune, wideband-verified tune, emissions certification, or guarantee of final drivability.

A base tune may include settings such as:

VATS configuration
Engine displacement
Transmission type
Injector data
MAF or MAP configuration
Fan controls
Startup airflow
Idle airflow
Startup fueling
VE or MAF starting calibration
Power enrichment
Speedometer and gear settings
Applicable swap-related diagnostic settings

A base tune cannot correct:

Mechanical engine problems
Vacuum leaks
Incorrect cam timing
Low compression
Fuel-pressure problems
Incorrect injector data
Wiring faults
Bad grounds
Sensor failures
Exhaust leaks
Transmission failures
Incorrect parts
Installation errors
Incompatible hardware

Cammed, boosted, high-compression, unusual, or heavily modified combinations may require data logging, wideband oxygen-sensor information, additional revisions, dyno testing, or local tuning.

The customer is responsible for monitoring engine operation and stopping use if unsafe conditions, detonation, overheating, low oil pressure, abnormal air-fuel ratio, misfires, or other problems occur.

Custom and Remote Tuning

Custom or remote tuning is limited to the work described in the purchased package or accepted quote.

The customer is responsible for:

Using supported and properly functioning hardware
Installing and configuring required scanning equipment
Providing accurate data logs
Using a properly installed and calibrated wideband sensor when requested
Following logging and testing instructions
Operating the vehicle safely and legally
Not performing unsafe testing on public roads

Additional revisions, major hardware changes, or tuning performed after the original service period may require an additional fee.

A revision is intended to refine the same disclosed combination. Changing the camshaft, injectors, MAP sensor, MAF housing, intake, fuel type, transmission, converter, power adder, engine displacement, or other significant hardware may be treated as a new tuning service.

Turnaround Time

Typical turnaround for supported mail-in ECU programming is approximately 2–3 business days after the ECU and all required information are received.

Turnaround estimates are not guaranteed.

Delays may occur because of:

Missing or inaccurate build information
ECU incompatibility
Hardware problems
Locked or corrupted files
Payment issues
Shipping delays
High order volume
Equipment failure
Weather or events beyond our control

Expedited turnaround is available only when confirmed in writing.

Shipping and Packaging

Unless otherwise stated, the customer is responsible for shipping the ECU to Midgard Industries.

The customer must:

Package the ECU securely
Protect the connectors and case
Use adequate padding
Include the customer name and order number
Use a trackable shipping method
Purchase appropriate shipping insurance

Midgard Industries is not responsible for damage, loss, or delay occurring before the ECU is delivered to us.

Return shipping will be handled according to the selected order package. The customer is responsible for providing a complete and accurate return address.

If a returned package is refused, undeliverable, or sent to an incorrect address supplied by the customer, additional shipping charges may apply.

Customers should inspect returned property promptly and report visible shipping damage within three business days of delivery. Photographs of the package, label, packing material, and ECU may be required for a carrier claim.

Midgard Industries will reasonably assist with a shipping claim but does not guarantee that a carrier will approve or pay the claim.

Unclaimed or Abandoned Property

Customers must respond to requests concerning an ECU, unpaid balance, shipping address, or service decision.

If customer property remains unclaimed for more than 90 days after written notice is sent to the most recent email address or phone number provided, Midgard Industries may treat the property as abandoned to the extent permitted by Texas law.

Before disposing of or otherwise handling abandoned property, we may charge reasonable storage, return-shipping, administrative, or unpaid service costs.

Refund and Cancellation Policy

Orders may be canceled for a refund before programming or custom work begins.

Once ECU programming, tune-file editing, custom calibration work, diagnostic review, or other personalized service has started, the service charge is generally nonrefundable.

Custom digital files and completed programming services are not returnable simply because the customer changes plans, changes hardware, sells the vehicle, or no longer needs the service.

If Midgard Industries cannot complete an accepted order, we may provide one of the following:

A reasonable correction
A replacement file
Reprogramming of the same ECU
A partial refund
A full refund for the unperformed portion

The appropriate remedy will depend on the circumstances.

Shipping charges, expedited-service charges, completed diagnostic work, and third-party processing fees may be nonrefundable where permitted by law.

Corrections and Service Issues

The customer must notify Midgard Industries of a suspected programming error within 14 days of receiving the ECU or tune file.

The customer must provide enough information to evaluate the issue, which may include:

Current tune file
Data log
Wideband data
Diagnostic trouble codes
ECU service number
Photographs
Description of vehicle behavior
Confirmation of fuel pressure, wiring, sensor operation, and mechanical condition

Midgard Industries must be given a reasonable opportunity to review and correct a verified calibration error before the customer seeks a chargeback, outside repair, replacement, or other remedy.

This correction period does not cover hardware changes, inaccurate build information, installation problems, unrelated mechanical failures, or customer modifications made after delivery.

Chargebacks and Payment Disputes

Customers should contact Midgard Industries before filing a payment dispute or chargeback.

Filing a chargeback for a completed and properly delivered custom service without first allowing a reasonable opportunity to address the issue may be treated as a breach of these Terms.

We may provide the payment processor with order forms, customer communications, tune records, ECU photographs, shipment tracking, delivery confirmation, and other documentation relating to the transaction.

Emissions and Legal Use

Customers are responsible for complying with all federal, state, and local laws governing vehicle modifications, emissions systems, registration, inspection, racing, and public-road use.

Midgard Industries does not authorize unlawful emissions tampering or the use of noncompliant calibrations on pollution-controlled vehicles operated on public roads.

Any competition, off-road, or emissions-exempt service is offered only where lawful and only for vehicles that qualify for that use.

The customer represents that all information concerning intended vehicle use and emissions status is accurate.

Vehicle Operation and Safety

Automotive calibration involves inherent risks.

The customer is responsible for:
