Ok guys wantin to buy a box. My truck has the 4:10 so i dont really need a box that comes on strong at 2500rpms. I need some thing that will come on at 1500-2000rpms. I want the low end torque. Which is the best way to go? Thanks for any help.

 

I'll second that, I too am not interested in improvements that only come on at high revs. Bigger injectors seem to be more expensive than a box, but they seem to offer more improvements across the lower end of the rpm range.

 

RPM's are higher with 4.10's than with 3.73's. Just an FYI...

yea thats right. with 4.10s your RPMs are about 10% higher than those with 3.73s.

But think about it: there are no boxes out there that can be distinquished between each other by how strong they come in at RPM differences of 10%. So your rear end gear ratio is of no consequence to the choice of fueling box.

But low end torque is a good thing, certainly, 4.10 or not. If I'm reading these forums correctly, TST is currently the king of low end torque, acheivable only via direct control over injection pulse width.

 

I agree,no box that i have heard or seen can make decent lower end numbers.Im about ready to make the move myself and i think its gonna be a set of D.D.2's and an Edge Ez,sounds like better low end,good egt's and no mileage decrease,or so im told

 

How's 1000 ft. lbs at 1700 RPM sound? Among the fueling boxes, TST is the king of low end torque -- it is very impressive.

2's and an EZ is great as well, but if you really do want to check out low end numbers with just electronics, then check this out

 

Points taken Doug,lol.I should have prefaced my selections with "I have a 48re and dont want to spend $4,000.00 in upgrades yet"lol. I hear a lot of talk about the T.S.T. and codes,i personally think they may have a bad case of "bugitis" although im sure they will work thru it.I just like the simplicity and results of the injectors/pressure box.Mark.

 

yup, good point. I hear ya on the simplicity. Actually have the same concern (complexity) of the TST box. that, and it is difficult to remove quickly. They'll get the bugs worked out though, you're right. But a TST on the lower levels with injectors might be another thing to consider. overkkill, but something to consider . Thats if you're like me and would prefer to keep the electronics from raising pressure. A TST without guages is not a lot more expensive than the EZ. the bonus is that you get power without stressing the fuel rail more than stock. the downside (in my opinion) is that the box is hard to remove quickly. then again, if you're committed to injectors, you can't return the truck to stock condition very quickly anyway.

BTW, if you're committed to a low end box, consider a pressure/timing box. Banks, Ramifier, others. to me, it sounds like these boxes might yield better fuel economy because of the timing capability.

man, think of DD2's plus the TST on low power settings. talk about low end grunt!

 

The only problem I can see is that the TST box will drop your fuel pressure to Zero without bigger injectors. I know that can't be good for the CP3. I would hold off untill some others do more research on the fuel pressure thing. I know I don't have any room to talk using an EZ, but I have never dropped my fuel pressure to 0.

 

Interesting points Doug.Have we been satisfied that the Ramifier does timing? I dont recall seeing any dyno sheets,seems like the pressure only boxes make their power at higher rpm's while the timing/pressure boxes make it earlier and longer.I just have tranny concerns with a TST,besides im hearing rumors of the stock turbo being maxed out on level 5/5.Dunno if its true,im sure the testers will let us know sooner or later.

 

So purchasing the TST might not be a good Idea? I dont want to always have my truck broke down. Maybe you could put it on hp-4 and tq-8 that should give you some low end.

 

Depends on what you mean by "does timing". In my way of thinking, The Ramifier box doesn't "do" timing. Timing may be affected by what the box does, certainly, but the box itself does not have direct control over timing. A box can only control or use those systems it is connected to, and the Ramifier is limited to the pressure port and the MAP sensor -- so it can only influence or take advantage of those interaces. But keep in mind that these are my current conclusions to date, based on lots of reading in between the lines in the absense of clear information. I may be wrong. the lack of clear information breeds speculation that may or may not be accurate. Dennis is telling us what he wants the public to know, and we just have to accept that.

What the Ramifier COULD do (but again I don't know this to be true) is influence the ECM by sending bogus boost levels. timing and duration could certainly be affected, within the stock parameters built into the ECM, but again be careful what you mean by "timing and duration". Make no mistake, the Ramifier is no TST. and don't be confused by the descriptive language. Ramifier probably influences small changes in timing and duration but not beyond stock levels of those parameters -- meaning that it could potentially bring in power sooner than the simpler presure boxes. But again, by way of contrast, TST takes direct control over timing and duration parameters and fires the injectors when and how it wants to.

re: tranny and turbo concerns. absolutely, the TST is capable of more fueling than the rest of the stock truck can deal with. With an otherwise stock truck, you'll have to resist the temptation to use the higher power levels. But this doesn't make the TST box bad, it just forces more responsiblity on the user. direct control over duration is to me an elegant way to add fuel while letting the ECM control pressure the way it wants to within stock levels. Turbo59pwr's suggestion is good I think -- use the lower power settings until and unless you have the other mods in place. No other box on the planet at this time is capable of direct control over the injection event. Especially at the lower power levels and especially without raising fuel pressure.

 

Okay, I'm going to play the dummy here. I'd like to "Chip" my truck but not for the reasons I see most guys want to. I have a 3500 for a daily driver. Okay, I know 40k workhorse doing a compact's job. But I wanted the diesel and the power. I want the chip for mileage. Is is possible to Chip the truck, get better fuel mileage, not loose any power, not void the warranty and not have to mess with any other parts?

I guess I want everything for nothing. Is this possible? Sorry for the ignorance I am a newbie to diesels

 

The short answer is "no"

Keep in mind that any time you modify the truck outside of stock parameters, you are taking on additional resposibility and risk in terms of the warranty. In particular, any time you add fuel beyond stock levels and work the engine harder than stock, you risk warranty coverage.

But there are approaches that minimize risk and maximize the potential to acheive your goals. A timing and pressure fueling box (there are a few out there, Banks comes to mind, I think Quadzilla is another, and there's more out there...) would be a good option. A enhanced pressure box like the Ramifier would also be fair game, but I'd expect a "real" timing box such as Banks to be better in the fuel economy department due to more direct control over timing (whether or not the difference is significant or important is not yet established). Anyway, there are lots of choices -- and you could run any of these adjustable boxes on one of the lower power settings, get the benefit of timing changes and fuel economy, and minimize mechanical risk to your engine.

But don't fool yourself -- you really want more power don't you . just kidding. But seriously, once that bug bites you'll be laying down rubber and having all sorts of fun, wishing you had more power, then more power, ...

So my advice is to seek out a pure timing and pressure box, and run it on the low power settings. Look for one that does timing only (I think Banks and maybe others will do this?) one of the lower power settings. But self control will be a word that comes to mind pretty quickly .

BTW, by "pure" timing I mean one that hooks up to the crank sensor and/or cam sensor.

 

Well, 4 out of 5 ain't bad
