DT466 CPS - Diesel Forum

PSDan000 · 12-31-2005, 12:31 PM

im sure this has been answered already, but will the dt466 cps that is being talked about so much in the super duty forum work in our trucks? i know they changed the connectors in 96 so im assuming it wont for 94-96, but will for a 97 [img]/ubbthreads/images/graemlins/shrug.gif[/img]. thanks

It should work. I thought the only change to the connectors was the contact coatings (zinc - early, gold - late). There was a current thread going on this, but I don't recall whether anyone is using it. Cheers!

OH NO!..........the rediculous CPS thread has invaded the dungeon now too [img]/ubbthreads/images/graemlins/tongue.gif[/img] lol.

If you want to change your timing, just do it with the program, don't jack it up in the program just to remove it with a cps lol.

I'm sure it will work but why?

Is that a reference to the High Performance CPS from International thread???

I have not read it yet, once it hit 6 pages I said screw it I am not even gunna try.

Yeah, it's totally out of hand, lol.

There's more than enough info on it up there, but as far as it going in your motor, the late OBS engines had the same sensor right?

well honestly i was just curious. with what i have read in the super duty forum (which wasnt all of it bc its over 20 pages now) is that the 466 cps helped increase mileage and made the engine run quieter/smoother (which would obviously happen with less timing). i figure it may be worth trying out, so why not?

Well, I could see how not having a chip that you can play with the timing on might make you want to go plop down over 100dollars for a cps to replace one that is working fine in your truck, but if you don't have a chip, and you're running stock PCM timing tables, then retarding your timing isn't going to help you anywhere except smoothness. I don't see how milage could increase with less timing than stock. For those running a chip with really advanced timing, I could easily see how retarding it a little could help out in many ways, but then again, if you have a chip, why not just change the timing yourself and keep the 100+dollars in the bank?

If you have a chip, change it yourself and keep your money, and if you don't have a chip, retarding your timing is not what you need.

IMO

I just don't see a place for it.

i personally have no way of programming my chip. a lot of people like to keep a spare cps in their truck so i figured with hearing good things about this cps why not give it a try, and hey if i dont really like it, i got a spare. [img]/ubbthreads/images/graemlins/cool.gif[/img]

johndeerebones · 01-04-2006, 01:41 AM

Just a thought, but couldn't you just slot the hold down bracket bolt hole and adjust it like that? Timing is playing with matches though. I don't think stock or even slightly modded would run right with too much timing, but with a little more than stock I would say you could toast something. Too much timing makes lotsa heat in places you don't want it. Maybe someone with more knowledge on the subject will chime in.

Guys, I've been following the "Blue CPS" thread in the SD forum and it seems like they might be on to something. So far, a lot of guys have tried it and most, if not all, report some benefits after putting a few miles on it. I put one in my '96 PSD about 550 miles ago and, I must admit, it does seem to be quieter and smoother. The power seems improved too.

I know all that seat-of-the-pants analysis is suspect at best and many people are suseptible to the placebo effect, but I have kept a log of fuel mileage for the last couple of years and continue to do so. We'll see how the DT466 CPS affects mileage in the next few tankfuls.

The latest theory on why this works is that the T444E commonly has too large of an airgap that the CPS has to read across. The DT466 CPS has a noticeably stronger magnet and is able to read across the gap more consistently resulting in a smoother running engine.

As for me, I'll be putting one in my wife's '02 soon and using the one I take out as a spare after putting on a new o-ring.

If the only benefit is a timing change, a chip would be a better way to go. However if the DT466 CPS provides a stronger more reliable signal, then that would be a reasonable reason to switch. I have over 80k on my current CPS, I may just pick up the 1807339C92 at IH and try it. Whichever I end up running, I'll have a spare.

Just checked Kurtt IH, $105 for the DT466 CPS, $12 less than the stock one there...
