[QUOTE="Rednaxs60, post: 227823, member: 4617"] Decided to bite the bullet and make a new ECU wiring harness. I had a spare OEM wiring harness from the 1200 carcass I bought in Ontario. There are a number of power/ground interconnections that I would think input noise into the OEM wiring harness. I have mentioned that I theorize that the newer aftermarket ECUs are more susceptible to issues with an older CFI system. Spent the morning removing the required OEM wiring needed for the Speeduino ECU: [ATTACH]49173[/ATTACH] The wiring on the right is what I need for the Speeduino - significant difference. The harness on the left is for spare parts. Have to splice into the OEM wiring for the output/inputs for the spark igniters, fuel pump relay ground, and injector signal to the travel computer. Have a few other connections to make as well. The MacBook Air has a new application called Freeform. Have been using it to do the new wiring schematic for the ECU install. One of the few drawing type applications I have taken to without a problem - have to be creative for some of the symbols. This is the ECU wiring diagram: [ATTACH]49174[/ATTACH] I still have the ability to revert back to the OEM CFI system. Wherever I have had to splice into the OEM wire harness from the new ECU wiring harness, I use OEM style connectors. A couple of more days for the wiring. Modifying the design to suit as I go.
