What a difference in Fuel Economy!!

[Subby]

How does this affect power/driveability when pulling?



Thanxs

 

[dmurdock]

this is all the info on their site:



This crankshaft sensor perfectly replaces the stock Cummins sensor, allowing a timing advance without codes or a voided warranty.



Improves mileage, reduces exhaust temperatures and reduces smoke and greenhouse gases. Undetectable, will pass emissions testing.



Two-minute installation



Made in USA



You do not need special tools to set timing, and do not have to worry about damaging "knocking". It will simply not allow timing to become so far advanced as to cause any damage.



The timing sensor is compatible with the following aftermarket boxes, as verified by users.

Banks 6-gun w/ speed loader, verified by users.

EDGE EZ, verified by users.

Quadzilla, all boxes, including race. Verified by users.

TS ramifier, verified by users.



We will add others as they become known. Let us know if you are successfully stacking one of these sensors with any other aftermarket boxes.

How much of an improvement in mpg when hand calculated? Many of the electronics will fool the onboard computer but not when hand calculated. Also there is a tendancy to drive different when you have an improvement that is designed to increase mpg. What are the real world experiences with this mod? At todays fuel prices it won't take long to pay for itself if it works as claimed!

Your First Mistake

RGardner

Your first mistake was to assume that I trusted an easily fooled idiot device on the overhead to tell me what my fuel mileage is. If you look at my auto signature you will see this is my 4th CTD since 97. When I post information it is accurate and proven. I do not drive it one bit different than I used to except for the fact that I don't hold the fuel pressure down as far as I used to because if I did it would get me a ticket because now the engine is running at the proper timing, not something to make some government compliance happy. My engine is happier at the 2 degrees advanced setting. I know of no one that has used it and had detrimental effects. some people only seem to gain . 5 to 1. 5 but they tend to be the 555 engines because they were not as retarded as the 600 and 610. The HO was retarded in order to meet 50 state CARB limits (thanks California). All i can tell you is that it performs snapier, than it did stock, the posted MPG results I gave you are Hand calced, the truck will have a decent additional amount of low end torque and your EGT's will drop up to 150 degrees. Please do not assume all TDR members do not verify before they post.

I did not mean to question your honesty or integrity, I was just asking? Maybe you should not wear your feeling on your sleeve!

Dewd! Lighten up!

Dewd. This is appears to be a major over-reaction. We all have read threads that claim things, ordered the part and then realized the claims may or may not have been true. When they were true it was with caveats or only in certain contexts.



He was just trying to decipher mods that seem to help and those that really help. Then at the end of his question, he stated, "At todays fuel prices it won't take long to pay for itself if it works as claimed!" I think this is a positive comment and I think his questions are fair. Hey -- I'm ordering mine today because I believe all the claims, especially for those with series 600 / 610 engines. But there is nothing wrong with trying to clarify and it's not a "mistake. "



From the ROKK technologies2005 website:

Will I feel a performance improvement with your timing advance sensor? What about my mileage?



You will definitely notice an immediate increase in torque from idle on up (about 5-20%, highest at idle), with a stock engine or a "chip" that does not alter injection timing (e. g. EDGE). This extra torque is most evident in manual transmission trucks, and automatics with low stall torue converters. In stock automatics the extra torque becomes most evident after torque converter lock-up.



If you use this sensor with a "chip" that advances timing, you risk over-advancing the timing resulting in knocking and reduced performance and engine life. For a list of user verified boxes click here.



Your fuel mileage will improve about 0. 75-1. 25 MPG (some users report in excess of 2 MPG empty, 1+ MPG heavy towing) depending on the fuel cetane, driving habits, etc. Your engine will run cooler also.



The cooler running engine has noticeably improved air conditioning performance due to less cycling of the compressor in hot weather, as brought to my attention by several users.



Based on some user reports, trucks that get especially bad mileage, such as 14-15 mpg empty, are brought back up to 18-19 mpg. This has to do with less soot being produced, which allows fouled-up injectors a chance to clean-up after a few hundred miles.

Just curious to a couple items, TST?? Sorry for my ignorance but whats that? Also, I'm very interested in the Rokk crank sensor - does it adjust the timing automatically or do I need to do this manually?



Anything for better fuel economy...

This looks like something I need to try... .



Tim from Illinois, is this thing ok to use???

The TST PMCR= TST Powermax CR (Common Rail). It is an electronic box that adjusts timing and duration. Sorry, not sure if it does pressure or not. I have noticed about a 1mpg improvement but I usually run it on 1/1 or 1/2.



The ROKKTECH sensor adjusts timing all by itself. Nothing manual to do unless you want to take the timing back down a little bit if you run a box that adjusts the timing. Their description of this is on their website.



Don't worry about your ignorance. Stick around this site and your knowledge will increase. I was dumb as a box of rocks about diesels before I joined.

Dually's with 48RE's do not get as good a mileage as the SRW's. My 04 only get about 14 in town and the best I've ever gotten on the road is 16. 97 mpg.



That's just the way it is.

This one is different in that department IMO. Boxes that add pressure are actually adding more fuel with less throttle input so its easy to see how the overhead would be fooled.



This mod adds no fuel, so in that case I would think you could trust your over head as a guide if it increased or stayed the same. The amount of change may not be accurate but if it goes up with no more fuel then I would think the hand calc should do the same.

Best of all, Rokktech crank sensor Works.

Installed mine a week ago, immediate improvement in MPG's. Oo. Oo.

Based on what I've read in this thread, I ordered one. Sounds like now my Banks setup will truly be a timing, duration, and pressure setup.

 

[steved]

Just ordered the crank sensor myself (after seeing the reviews).



One question, how do you set the timing... or is it just bolt it on and it is there? I have no mods other than exhaust and airfilter.



I have never messed with timing on a CTD before... I guess what I'm asking is how do you check it or is it just trust what you get is right?



Thanks,

steved

 

[TexBamBam]

Just ordered mine too... hope it kills the KNOCK...

Actually, the more you advance the timing (2 more degrees in this case), the more you're susceptible to pre-ignition. I don't think this is a knock alleviator -- but can give you a knock if you don't have one.

 

[steved]

How do you know when you have enough or too much? Is this a guessing game... trial and error... or just dumb luck??



I guess what I'm asking is whether this is just a simple swap or if you need to somehow measure the timing to confirm what you did??



steved

 

[67guzzler]

Trial and error, if necessary. It might not be necessary. But if you're combining this with other mods, cetane boosters, biodiesel, etc... then you have to monitor it closely to see what effect it has.



If you have no other upgrades that already advance the timing, then this can add between 0 and 2 degrees of advancement to stock timing. The starting point should be the full advancement and then drive the truck. Depending on your fuel quality and if you do or do not use a cetane booster you may or may not have a knock at lower rpm's. The instructions suggest that if you use a cetane booster it might knock and they suggest you stop using it. They imply that more times than not that will stop any knock.

 

[steved]

Good deal... sounds like it is a plug and play, then adjust as necessary.



I don't have any "computer" related mods... just exhaust and airfilter. I was going to buy a box to get the benefit of the mpg gain, but didn't really want the added power. So this sounds like the ticket.



I take it the knock is very apparent? Last thing I want to do is damage anything... I occaisionally run a cleaner/booster through... running Marvel Mystery Oil right now, but don't on my cross country trips since it makes the fuel red.

Rokk the pup

Anybody tried a ROKK with a Power Pup? If so what setting on the pup?

 

[TexBamBam]

I got the knock now... but at least it's on all 6... . not just one like before. I like the sound and the fuel economy... + 1. 2 MPG
