Why HP Tuners for US cars?
Cars from the American market (GM, Ford, Dodge/RAM, Jeep, Chevrolet, Chevrolet Corvette, Cadillac, Buick, etc.) differ in their ECUs, strategies, and security. HP Tuners gives us:
- Deep diagnostics (VCM Scanner): live logs, hundreds of parameters, active tests, quick fault analysis.
- Control over calibration (VCM Editor): access to key fuel, ignition, torque, boost, and transmission maps.
- Full documentation support: datasheets, calibration guides, and technical notes - we don't rely on "off-the-shelf" solutions.
- Secure workflow: backups, calibration comparisons, change validation, logging every step.
What do you, as a Client, really gain?
-
Better throttle response and flexibility – the car pulls "from the bottom," without dead zones.
-
Stable, repeatable power – without jerking and "floating" AFR.
-
Lower EGT/oil temperatures during dynamic driving (correct mixture and ignition).
-
Smoother, stronger gear shifts (AT/TCU): optimization of points, pressures, lock-up times.
-
Adaptation for fuel E10/E15, 95/98/100, Flex Fuel.
-
Disabling inconvenient functions: e.g., DOD/AFM in V8, start-stop, speed limiter, VATS after SWAP, etc.
-
Full documentation with measurements – logs, graphs, description of changes, service recommendations.
Our process
-
Interview and goal – what are we focusing on: off-road, comfort, track, city/highway, trailer towing?
-
Logs + diagnostics – we identify real limitations (fuel, ignition, EGT, TCU slip).
-
Dyno baseline – initial state (power/torque, AFR, IAT/ECT/EGT).
-
Calibration with HP Tuners – edit → logs → verification.
-
Road test – different driving profiles (city, highway, load).
-
Final dyno run – results + documentation package and recommendations.
HP Tuners innovations that make a difference
-
MPVI4 - fast read/write, stable communication, logs
-
Broad ECU/TCU support for US brands and constant definition updates.
-
Documentation and dev community – real descriptions of masks, not "forum legends."

FAQ
What determines the pricing?
Depending on the ECU - HPtuners credits are a cost on our side. Dependent on the complexity of the project and engine generation.
Does changing the map void the warranty?
It can. We inform about the risks before starting.
Is a dyno necessary?
We recommend it. It gives us a baseline and repeatability.
Will you only do the transmission (TCU)?
Yes, as long as the TCU is supported.
Do you deactivate DOD/AFM/MDS?
Yes.
