this is a Speeduino based project regarding the modification of Magneti Marelli IAW 1AP ecu's to run on Speeduino firmware. These ECUs are found on several cars, but the board Layout is pretty much the same.
Speeduino is a powerful yet economy DIY totally open source (Hardware and firmware) Engine Management System (EMS) growing all the time and new features are added regularly.
- Support for 1-8 cylinder engines
- Fully interpolated 16x16 Maps
- Open and closed loop boost control
- Extensive list of supported crank patterns
- Detailed and high speed logging
- VE Analyze Live ('Autotune')
- Secondary map switching
The process brings to mind the old-times where we used to hard-wire PlayStation boards with modchips.
It requires soldering - desoldering skills and tools.
BEWARE!: you have to desolder both CPUs and EEPROM, you cannot undo the modification of your ECU. It is recommended to find a spare used ECU
All the work is a reverse-engineering method made by myself using a multimeter, an oscilloscope and some experience ;)
Best regards to my friend Dimitris Manolakis who inspired this project, donated his engineer knowledge and his car for tests
Voila!
