58750 ohms at 10 degrees??? shite....you sure its not 58.75 ohms?
Not a good idea to meddle with as you will move away from the optimal fuel air mix.
that was my point - at the moment most of our (6 cyl) cars (mine especially) run too rich at WOT, if we can lean it a little we get more power as well as less fuel consumption - i think the guys at the SA dyno day all saw hp gains on a dyno with an adjustable fuel pressure reg on their cars, set to less pressure than stock = leaner mixtures.
sure it will help at WOT, but what about closed loop lean burn cruising. It will run even leaner, i dont want to be the one with a burnt piston.
dont have to worry about that - at cruise the car is in closed loop mode - it pours in the fuel then checks the exhaust gasses to see if its too lean or too rich, then adjusts accordingly. the comp will learn fairly quickly to add a little more fuel than it thinks it should.
or you could put a switch on your throttle pedal that only adds the resistor to the circuit when the car is at WOT - easy.
i believe the optimum AF ratio for the I6 is about 12.7:1 or 13:1 of thereabouts, gotta figure out what amount of degrees temp above actual to send the computer to get it to go from 10:1 (which it is atm) to that figure...i suppose we would need to look at the fuel maps in the computer to get it right....or buy a few resistors and organise some dyno time, and just go trial and error.
is anyone keen to do this? i have a an aftermarket computer on order so its not a big deal for me, but if somone wants to save themselves the cost of a fuel pressure reg it might be the go.
what if we tell the comp that the air temp is 40 degrees instead of 30, we would need to get the resistance down from 24270 to 16150...anyone know how thats possible using a paralell circuit? i have totally forgotten how to work it out..
