Hello,

here are PnP ECUs for Mazda Mx5 I designed. They all fit original ECU cases, come with step-by-step manual and have preloaded maps for particular car model/engine to have as much as possible features running out of the box. In stock car installation time is within 15 minutes.

specification
• 4 injector outputs
• 4 spark outputs. Works with stock ignition and COPs wasted spark or full sequential
• high current outputs for idle control, boost, VVT and spare (nitro/WMI)
• medium current outputs (0.5A max): fuel pump, fan, tacho, EVAP, VTCS/VICS, main relay
• built in MAPsensor 2.5bar, Baro sensor (mk2.5 optional, stock one can be used)
• hardware alternator control (mk2 mk2.5) with programmable BATT lamp
• works with stock o2 sensor or wideband using external controller via dedicated 0-5V input
• additional inputs:idle up (PSP), clutch (launch control/flat shift), VSS, 2 x analog 0-5V (fuel and oil pressure sensors)
• 2 digital FLEX inputs (active pulling to GND) for additional functionality for instance fuel/spark map switching
• software AC control
• Bluetooth option (serial0)

STP62NS04 mosfets are used for high outputs because boards were designed during chip-shortage period. New revisions will be with automotive-grade VLND drivers. Updated mk2.5 version works on the bench, waits for testing in a car

Are these available somewhere as components/kits or already assembled ? Would love to give it a try?
