Rev-matched downshifts on every corner entry, without heel-toe. It plugs in at the pedals and never touches your ECU or your tune.
01 / How it works
The module sits inline between your accelerator pedal and the ECU. It watches two signals your car already has, the brake light circuit and the clutch switch, and blips the throttle for you when it sees a downshift.
The module sees the brake circuit go live and arms itself. There is no time limit between the brake and the clutch.
Brake first, then clutch, is the downshift signal. Press the clutch without braking and nothing happens, so your upshifts stay untouched.
An internal relay switches the pedal signal to our programmed blip for a set number of milliseconds, then switches back. The revs come up and you release the clutch on a matched gear.
The module watches the brake and clutch circuits for their 0V-12V transitions and never injects voltage into them. It does not over-volt the accelerator pedal position sensor (APPS) signal, so it sets no diagnostic trouble codes (DTCs).
02 / How the blip behaves
The module sends your ECU the same throttle command on every downshift. How much rpm that command adds depends on where the engine is when the blip starts. Start higher in the rev range and the same blip gains more rpm.
The driver brings the revs up with his foot, lifts off the throttle, then presses the brake and clutch, exactly like a real downshift. That triggers the blip, and the tach shows how the engine reacts.
Every blip in this clip is 80% for 180 ms. The command never changes between runs. Only the rpm it starts from does.
Blip from lower rpm and the revs rise less. Blip from higher up and the identical command adds more. That is your engine and drive-by-wire responding the way they would to a heel-toe blip at the same rpm.

03 / The install
Inline harnesses at the throttle pedal, brake switch, and clutch switch. On 100% Plug and Play kits there is nothing to cut and nothing to splice. Most installs take 1 to 2 hours, and most of that time is on your back under the dash.
Every step of a Plug and Play install, start to finish.

Every module ships pre-programmed with settings for your platform, and most drivers never change a thing. If you want to tune the feel, plug in over USB.
| Parameter | What it does | Standard |
|---|---|---|
| Target throttle blip (%) | How deep the programmed pedal press goes | 50% |
| Blip duration (ms) | How long the blip is held | 300 ms |
| Minimum time between blips (ms) | Buffer before the next blip can trigger | 300 ms |
| Delay after trigger (ms) | Wait before the blip fires, for a sensitive clutch switch | 0 ms |
Some platforms ship with their own defaults. There is no calibration or pedal learn procedure at first setup.

05 / Behind the wheel
The module only reproduces the pedal voltages your own foot would. It does not alter your ECU, calibration, or tune, so it runs fine on tuned and forced-induction cars with stock pedal wiring.
Pedal maps are built from OEM pedals measured on an oscilloscope. The module does not over-volt the APPS signal, so it sets no DTCs.
100% Plug and Play kits include an on/off switch. Flip it, even while driving, and the pedal signal passes straight through to the ECU. The car drives exactly like stock.
The pedal harness uses inline OEM connectors. Unplug it and your factory wiring is untouched. On Plug and Play kits, nothing is cut or spliced anywhere.
Factory systems read a sensor in the shifter. We use the brake and clutch circuits your car already has, so you get downshift blips on cars that never offered factory rev matching.
The module has no gear, speed, or rpm input. Brake then clutch at a standstill will still blip. In traffic, press the clutch before the brake and it stays quiet, or flip the switch off on Plug and Play kits.
