Got the parts I ordered from https://www.diyautotune.com this Friday. I have now spent a couple of hours to build the Relay board and the MegaView unit and it did work at first attempt.
The Relay Board will be mounted in the engine bay and is connected via a DB-37 cable to the MegaSquirt ECU, 12V power supply, all sensors and injectors are attached to the Relay Board. The MegaView board are connected via a standard serial cable to the ECU. MegaView is an add-on accessory for the MegaSquirt system, providing real-time display of all engine operating parameters, and allowing for the edit of any configuration variable in the MegaSquirt ECU.
I'm now planning to mount all sensors used by the MS. By doing this I can monitoring all parameters and tune the system while I am driving the car still using the CIS system. When everything looks ok...
- Remove the CIS system's fuel distributer and injectors...
- Put the new Bosch injectors in place...
- Connect fuel hoses to the fuelrail and off we go...
