I have completed my MPGuino kit from Fundamental Logic and here it is...
The buisness side...
The looking side...
Powered by USB...
I was going to show the step by step of assembly, however Fundamental Logic has already done a fantastic job of it on their web page so I decided to not reproduce their work. I do intend to make an enclosure for it at some point in the future but for now I'm going bare circuit.
I found the ECU pinout for the 99 Civic LX that I plan in installing the MPGuino into.
On connector B, pin1 is the 12V supply, pin2 is the ground and pin3 is the signal line for the second fuel injector.
On connector C, pin23 is the signal form the VSS.
Having identified my splice locations, as soon as I purchase some phone wire I will start the installation process. More pics to come.
