I see this over-looked... A LOT.
WHY are the ignition systems between the JDM and USDM VH45DE's different?
-My JDM engine I bought has no Ignitors on top of the valve covers, and is confusing, since they cut the harness on both back ends... :/
If/after I make a sub-harness... could I use the USDM ECU with the JDM coils (directly wired to the ECU) with no problems, or would I need to switch over all the USDM coils and ignitors?
Which of the two systems would be more efficient to use..?
-I have both a JDM and a USDM engine...
-I have 2 (3 now) USDM ECUs, not the JDM president one
-JDM harness was cut, so I got 2 USDM harnesses
Pictures of the problem i'm talking about shall follow..
Any serious info
anyone can give me would be GREATLY appreciated.
Here's a pic of the JDM harness, without ignitor box, it just directly wires into the harness...
Here's a pic of how the USDM version looks..
Anyone else come across this? What did you do?
Also, I apologize for the novel... lol
