I'm really hoping this is the correct place to ask this question, and I apologise if it isn't!
I have an Rx7 S7-8 pnp G4+ Ecu that I'm using on my Bridgeport 13b.
I'm ditching the stock ignition set-up in favour of the LS1 coil packs that are known to handle ignition demands much better in higher power situations. I'm hoping to figure out a way to run the leading plugs in direct fire, the same way the trailing plugs are. As the coil packs will struggle at higher RPM in the original wasted spark set up.
I've found the factory three ignition outputs from the ECU for Leading 1 and 2, Trailing 1, and Trailing 2 and I've de-pinned them from the Ignitor plug ready to wire into the LS1 Coils. I'm now at a loss as to what to use for Ignition 4 as according to the manual that has been appointed to the Aircon-clutch (Which I intend to keep in the car). Is there another output I can set that to? Or will I need to purchase an expansion loom to gain Igntion 5,6,7 and 8. (I'd rather not purchase an expansion connector if avoidable, just to be able to run one more Ignition output for direct fire). I've used the help system to determine how to change the ignition mode to "Rotary - Leading Direct".
I'm sure there is a very simple answer I'm missing and I apologise for that in advance!
