[QUOTE="Rednaxs60, post: 230377, member: 4617"] More thoughts on this type of project. Have most of the components that I think are needed for a pilot project, bench test of such a project. Need a Hall Effect sensor, wouldn't hurt to have a spare available. I have the 36-1 trigger wheel. The 1500 engines have a 12-1 crankshaft trigger wheel that will work as well; [ATTACH alt="ICU Replacement Trigger Wheels.jpg"]50218[/ATTACH] Engine timing mark pointer, yours may differ, but this is the concept - just have to miss the timing belt. This picture is what I have installed on. my engine: [ATTACH alt="Engine Timing Pointer.JPG"]50219[/ATTACH] This picture is what I had installed with the 36-1 trigger wheel, two different setups but achieve the same aim: [ATTACH alt="Timing Mark Pointer.JPG"]50223[/ATTACH] Marking the 36-1 crankshaft trigger wheel for timing is easy. Each valley is approximately 5 degrees of timing, as is a tooth - the width of a tooth is approximately 5 degrees of timing. A piece of tape on the 1500 trigger wheel and marked for #1 TDC and then mark 4-5 mm for each 5 degrees of engine timing. 36-1 trigger wheel with timing marks: [ATTACH alt="Timing Mark - Trigger Wheel 3.png"]50220[/ATTACH] The CLT sensor can be installed using a coolant pipe from an FI model: [ATTACH alt="Engine 5 - 1.jpg"]50221[/ATTACH] The IAT sensor can be installed in the air box lid.

An engine simulator such as one of these: [ATTACH alt="Engine Simulator 2.jpeg"]50222[/ATTACH] Edit: have the software and some spare Arduino Mega 2560 microprocessors so I can do a mock tune (I think). Have some more homework to do, but a plan is coming together. This will not be a "quick get on with it" project. More to follow. [/QUOTE]
