Thanks
This makes sense. I would be willing to bet that the stronger magnet is a fix for the different depths that are in use due to the machining/casting variances of a mass produced part. So basically you take the old sensor that can't detect much due to the big gap and replace it with a new one with a stronger magnet.
OR you could just tear down the front of your PSD and mill/sand/machine it if it needs to be tightened up. But since that is costly they just produced a stronger (magnetic) part.
Hope this helps.

Since I started this thread, it is my duty to be the bearer of bad news. See this post:

Now that its running though, I put bluey back in just so I could know if it was a problem, and poop. Truck would not go. The black one is in and its ok. I wonder if DPP will replace or refund this thing since I've only had it a month or so.

Sanding and or grinding down the cover is not a big deal. It can be done with out removing anything but cmp. I use a 3m cookie wheel to do the job. I have also had to do this many times with the DT 466E which uses the blue sensor. It all comes down to getting the correct air gap regardless of what sensor you use. All the navistar engines used to come through with shims on the cam sensors. Shims and + or - on parts are due to poor/innacurrate machining which keeps costs down in the end.

I took the blue CPS out last night. I wanted to see if I noticed a differance. I had the blue one in for 2-3 months now. And I did notice a change. The truck doesn't start as fast, Throttle response is a bit sluggish. I don't know about mileage yet. But I will.

If they could fix at a reasonable cost as to why they fail so soon, I would think they would. They have had numerous updates and revised part numbers over the years trying to repair the problem. Navistar did away with this sensor in their new engines VT 365 and the I 313. I still don't get why people install parts that were not meant for there application and then recommend it as a great mod two days after the install, especially with no testing done to verify as a good replacement.

When we do something and the SOTP labs that we use here OKs it, we get the word out. I'm afraid if Ford had it, we still wouldn't know about the Kwik Filter or the fuel bleed systems that Kwik came up with.

Things have gotten quiet in other places about the blue cps. Even the sites that were pushing them hard with their "improve mpg" advertisements are no longer promoting them as much. Me thinks somebody knows something.

Hmmmm. Oh well. I guess I get to keep runnng my blue one because I like the way it runs with it. I'm glad I ran across this thread because I found a simple, inexpensive way to increase my mileage and and quiet my engine down (if only slightly). I say inexpensive because I needed a new CMP sensor anyways for a spare (which is the black one now).

SOTP feel is nothing. Understanding what you are doing and why it does what it does is the important part. Any idiot can change a part.
The KWIk mod and the fuel line mods are nothing more than a variation (homemade version) of what navistar puts in there 3000 and 4000 series trucks and buses. Its nice to see somebody offers his ideas without a price tag to people that don't know what works and doesn't instead of stealing there money for a mod that doesn't work.
