Introducing the SM3+ Micro!!
Everything you need for a proper standalone ECU, in a footprint that fits where nothing else could.
⚡ 4-cylinder full sequential
🎯 2x VR/hall inputs
📊 Onboard MAP sensor
💾 Onboard datalogging memory
🕐 Onboard Real-time clock
🔗 CAN bus
🛜 Onboard wifi/BT connection
🛠️ Our Custom firmware based on MS3 1.4

Same tuning software. Same power. Fraction of the size.

Coming soon.

⏰I know we said we wouldn't do CAN dashboards… but I couldn't sleep the past few nights, so 😅

💥Introducing KPDash running on the affordable Waveshare boards with onboard CAN hardware, available in 4.3", 5" and 7".

We built a full drag-and-drop designer for it fully customisable from fonts, colours and backgrounds to gauge layouts and warning behaviours.(Same style as our upcoming PDM)
Design your dashboard in the browser, drop the layout file on the SD card, and you're done.

✅Comes with presets for MegaSquirt, MAXXECU and SM3+ out of the box.
✅Custom CAN data?
No problem you can define your own channels for anything on the bus. Set up shift lights, tachos, gauges, bars, warning lights, alerts, GPS track logging(it will draw on screen track read by GPS data), RTC clock, night mode… whatever you need.

💰ESP32-S3 based → cheap, fast, powerful

‼️‼️On top during testing we found a bug in our custom SM3+ firmware,created by the multispark option!! Please download the new fixed firmware from the webshop‼️‼️

💣MAYOR UPDATE💣

Downlaod link Custom firmware and flasher:
https://kperformance.be/index.php?route=product/product/download&download_id=85

This took a serious amount of time, stubbornness and a healthy dose of autism, which is either a blessing or a curse depending on the day. 😄

Started from the MegaSquirt 3 1.4 source — the old 2016 dinosaur 🦕 — and built our own firmware on top of it.
Not a quick patch: reverse-engineering how the thing is put together, working inside its banked memory layout

✅The result is a proper SM3+ v2 firmware its still a WIP

Credit where it's due: MS3 is a solid, proven platform and a foundation worth building on. We didn't want to replace it rather add the stuff people kept asking.

What's in it:

✅ Our TinyO2 wideband over additional serial port — full digital data, no wasted ADC input
✅ Drive modes (Street / Sport / Race / Wet) — each one reshapes boost, fuel, ignition, launch RPM and traction control
✅ Haldex AWD control over CAN, tied to those drive modes
✅ RPM-adaptive misfire detection, tied into the engine light functionality
✅ EGT boost clamp — backs off the wastegate as exhaust temps climb
✅ ITB idle and overrun fuel-cut on individual throttle bodies, where the MAP signal is useless
✅ Coolant overtemp protection — warn, limp or cut as temps climb
✅ Resistor ladder inputs — read multiple buttons or switches off a single analog input
✅ Blink Marine keypad over CAN bus — with detection and LED feedback
✅ Stop / resume the engine from a button

Still on the list: on-board drive-by-wire and common automatic gearbox control.

We're staying on the MC9S12XEP100 — genuine automotive MCU, built for engine management. New software, proven hardware.

Need an integration or a feature?
Ask and I’ll try to make it happen — some of what's in here was added on request, like a few features we built for Wicked-Performance.

💥 TinyKnock – know what's happening BEFORE it's too late

An engine that's knocking and you can't hear it 💥 broken piston, snapped rings, or worse. 💣
A knock controller isn't a luxury, it's insurance.

The TinyKnock gives you real-time knock detection on your dashboard AND over CAN to your MegaSquirt,MaxxECU,Link or any other capable CAN logger

✅ Plug & play CAN integration (TunerStudio Passtrough compatible)
✅ OLED display so you see live when your engine starts complaining
✅ TPIC8101 chip – industry standard
✅ Works with the knock sensor you probably already have
✅ Analog output and/or CANbus data
✅ Auto Calibrate function

Ever thrown a piston from detonation? Once is one time too many.

🔥 TinyDBW — Drive-By-Wire for your MegaSquirt 🔥

Want to run a modern electronic throttle body with your MS3? Soon you can!

📸 Throttle body + electronic pedal + our TinyDBW controller = done.

✅ Plug & play MS3 passthrough — configure everything straight from TunerStudio, no extra software needed

✅ Dual channel 6A peak— run two throttle bodies (V6/V8 setups), or use channel 2 as a wastegate / boost control / supercharger bypass actuator

✅ Idle control built in — set your target RPM and let TinyDBW handle the rest

✅ Cruise control built in — works with VSS from MS3, brake cancel, stalk input support

✅ Safety first — soft &hardware watchdog, limp mode, plausibility checks on pedal & TPS sensors, fail-safe throttle close on fault

✅ Compact, CAN-based, easy to wire

✅ Designed and built in Belgium 🇧🇪

⚠️ Still WIP — final testing and validation coming up. Stay tuned for the release!
Ditch that cable throttle. Go DBW. Go Tiny.
