Never used anything but the original wetter stuff. I am digging around the PET CD to see if there is more info on upgraded cooling systems. Also curious mainly, no real problems.

No, - Does it improve the taste of straight anti-freeze?

It's the controller that is mounted in the nose, I believe. I looked around a little, but have had no luck finding any info regarding upgrade.

I plan on bypassing / redesigning.

Looking at the specifications that jayC67 posted above, I think it is an elegant solution as designed.........
Let me know what you do.........oh fellow "blown-sharkster"......

P.S. at one time I looked up the wire diagrams for this and from what I remember, it "should" be a plug and play swap from as far down as 1989.
