hi everyone.

I have a is300 2005 and doing a budget build

Just a question as i have a greddy emanage ultimate to be wired up to the stock ecu.

My question is the ecu has 3 ingition inputs how do they wire into the emu?

Do you cut them and splice them to make 6 inputs to the emu then 3 back to the ecu?

You cut the three wires and “butt” the emangle in between the stock ecu and the igniter. So three in Emanage, three out emanage. The is300 runs a wasted spark config so it has three coil packs for all six cylinders. If you look at the coil packs, you can see how the cylinders pair off 1-6, 2-5, 3-4. So a spark is wasted each time because one cylinder is at compression phase (active) and one cylinder is at exhaust phase (wasted).

I don’t have the manual and I am too lazy to search for it. That sounds right though. It’s a series connection, so out of the stock ecu > emanage> igniter. The wires are easiest to intercept in the ecu box. Same for injection, but there’s six wires.
