fyi...my crank sensor is a plastic bracket with metal bushings as well, on a '98. looking around for a used one. not even going to try to modify the plastic one.

This mod will advance the intial timing.Think about this...The computer in your DAK is designed by engineers that contemplate and anticipate the changes in your driving.The computer is designed to read varying inputs and decide what the best output will be..Enter the crank sensor..The input,and therefore the output on this device are dictated by a FIXED sensor.That is,the computer thinks this sensor does not move nor, is it capable of moving(just like IAT).The engineers don't anticipate every dak owner doing this mod.So, in sync with their thinking,the PCM cannot recognize when you move a fixed sensor.The PCM sees the crank sensor as never moving.Once it is moved,the computer has no idea that it has moved,it can only detect knocks or pings and adjust timing as it(PCM)sees fit.So it is correct to say the base timing is advanced while it doesn't neccesarily change the behavior of the PCM when it detects a situation which warrants the advancement or retardation of timing.These adjustments will all be done as compared to the base timing.And the base timing is changed when you do this mod.So you will see differences with this mod,be they good or bad.and nobody here can guarantee it's success or demise.

Good description, but we CAN guarantee that an extra 4 degrees of timing will give you better performance over the stock setting. You'll just need higher octane if the extra advance makes your engine knock.

Did the mod a few mo.s ago. Noticed no performance increase. I only notice the idle slightly higher during cold start warm up. Thinking about undoing mod. and getting a coil. Why change things just for the sake of changing things if there are no significant improvements?

I wonder if the newer models don't notice such a difference in performance and gas mileage? Seems that others with older Dak's notice more improvements than the newer models.

I would guess that some owners are just more perceptive. Mj's idle increase is from the extra power from this mod and present throughout the whole rpm range, but he just doesn't notice it. I don't know why he would consider undoing the mod to try a hotter coil, those mods would work fine together. If he wasn't happy with this mod, I don't think he'll be happy with the coil either. I doubt he saw as much increase relocating the IAT. Small gains can add up, but can be hard to feel as you go.
