[QUOTE="Rednaxs60, post: 226982, member: 4617"] Resurrecting an older thread. It's time to get on with this project. Have been reviewing notes, forum threads, Speeduino information. Have the bones for the replacement ECU, Speeduino board and such. Time has a good way of clearing/focusing a person's thoughts. I realize from my renewed reading, that I am just replacing an older ECU with a newer one. This does, or should not, require any wiring or component changes. There will be some reduction in the components used such as the cam sensors - have two, only one required. A new trigger wheel, thinking 16/24 tooth, no need for the missing tooth aspect because of the cam sensor. I do lose a bit of functionality. The OEM ECU diagnostic program, as well as the dash indicator light. The cam sensors, Gr/Gl, were Honda's answer to sequential injection and faster starts. My reading indicates that the benefit of sequential injection instead of batch firing is not that much. The Speeduino can use either. The Speeduino does not need to use a cam sensor, but that would require a missing tooth trigger wheel. I have updated my pin-out spreadsheet. Have the 95% solution regarding this. Need to get the components out, get Tuner Studio and such back on line, and read the Speeduino info again. Have not been on the Speeduino forum for some time. Cheers [/QUOTE]
