Let me elaborate on the ignition switch idea, anytime the key is on the fan would be on. I have had some wiring bugs, but I have sorted them out for the most part. Here are some of the pictures of what I did.
This is how much crap wiring I removed, along with 2 non-functioning relays.
Here is the temp probe poking through the radiator.
I reused the the factory fan plug for easy removal.
I mounted the new relay behind the headlight on a factory bolt.
Also, I have been playing with the idea of killing 2 cylinders while cruising ( not while idling or accelerating) My car runs OBD0 so I only have 1 o2 sensor, and because I have tubular headers the o2 sensor only reads cylinder 3. so I do not have to worry about it trying to richen the mixture, because 2&3 are not affected. If I kill 1 & 4.
This is the firing order
When I disconnect 1 and 4 it remains balanced, and will idle and run (slightly rough at an idle) and will sloooooowly get me up to 75mph without a problem. above 2000 rpm you can not feel/here the dead cylinders. Also, it will pull small hills without a problem.
You do have to have a more aggressive throttle position, but that is to be expected with half the effective displacement.
By shifting the load of all 4 to just #2&3 (by deactivating them) to the remaining cylinders should operate under higher higher effective compression ratios.
Does this sound like it would work ok?
As a way to avoid the CEL, I will not be simply "Cutting the power" to the injectors, I plan on making the go to an alternate circuit with a ~6ohm resistor to fool the ecu to saying the injector is firing.
Any feedback would be awesome and appreciated!
