HObduino PNP v1.0

Step up in the Honda mapping game with this 100% brand-new standalone ECU, tailored for Honda B/D/H/F series engines installed in 1988-2001 Honda.


HObduino PNP is a standalone ECU based on Speeduino (Arduino MCU) with a modified software and hardware designed to suit Honda OBD1 and OBD2 distributors: no engine modification is needed to run the HObduino.


This new system runs with Tunerstudio: a powerful tuning software offering a complete list of features for fine-tuning all your engine maps and parameters.


Tunerstudio free version includes basic tuning to get you started, but some extra features are only available in the paid version (VE auto-tuner, high-speed analysis, etc.)



  • Complete standalone ECU based on custom Speeduino 0.4
  • Plug-and-play on a OBD1 Honda, no wiring modification needed for basic N/A tuning (needs a conversion harness on OBD0/OBD2 engine loom)
  • Real time programming with Tunerstudio software


Extra features included:

  • Coil-On-Plug output (using OBD1 "C" connector plug)
  • E85 Flex Fuel (needs a flex-fuel module)
  • Boost Controller
  • Optional LSU 4.9 AFR controller module
