I've got a E6K and need to install it, I still have the stock ECU. Have anybody install an E6K with out having the stock ECU install with the stock wiring? Can I install the e6k with the supplied wiring while keeping the Ignition system in (stock system;igniters and crank angle sensors).
Where can find the wiring diagram for an Install E6K in a 3rd gen rx7?

 

The E6K is supposed to replace the stock ECU and stock wire harness. The E6K wiring can be used with the stock CAS, ignition coils, and fuel injectors. It should come with its own TPS, coolant temp sensor, air temp sensor, and manifold pressure sensor. The manifold presssure sensor may have to be changed depending on what your max boost is.

 

its a universal thing.... the only thing you really need to worry about is ignightor and CAS and your e6k should have come with 2 seperate pieces of paper with diagrams for each. if it didnt, ask the dealer( who sold it to you ) for them....

on the 3rd gen you are able to use the stock TPS. the air tem sensor you will need to tap a 14x1.5 for if memory serves, and the coolant could either screw right into stock threads or you may have to tap a 3/8 for it dependign on what sensor you were sent.
other than that, you will only need to wire fuel pump which you should get the white/red wire under the brakecylinder because there are no relays after that point, and will need to wire you injectors up.
if you are no using any of your stock harness, you will need to strip out the trany side of the harness and do some small things in the kick pannel.
email me at rxrotary2_7@yahoo.com if you run into any problems.

 

Well if I can get the wire diagram to wire the CAS and ignitor circuit I will proceed to strip out all my stock wiring going to the stock computer. Can you lead me to where I can get that diagram?
And about the stock instruments which wire do I use for RPM indication on the stock gauge if i will pull out the stock harness and computer, and is there anything else the stock computer provides for indication in the instrument cluster and comfort like the Air condition.
