Tuning box questions

[krabman]

Might want to head over to the DTR. A fellow has posted a response from VA on the addition of timing to the duration box. It isnt good news for folks who bought the duration box. http://www.dieseltruckresource.com/dev/showthread.php?s=&threadid=46358

I would hope for a trade in program as well! I know I bought my VA early and I still am very pleased with it. I am hoping for timing to cool off the EGT on the full setting. In the meantime I was thinking of looking at the Volumizier. If I'm not mistaken it does some timing (although not sure how looking at the connectors in the web pic!) and some pressure. Maybe the timing will help on the EGT's, that and maybe a little water injection... ... ... .....

Well, lets hope for a trade-in program similar to what Edge was talking about for EZ owners wanting to upgrade to Juice.



the volumizer is like the Ramifier in its pressure function, plus it adds a touch of timing (it connects to the cam and the crank sensors). From looking at the HP figures I'm not convinced that there is much timing in the Volumizer. Its strengths are a lot like the Ramifier -- it remaps boost signal (tells the ECM that boost is really higher than it is) so the low end is very strong. Yet, at the top end at high HP / high RPMs, it is on equal footing with the other pressure boxes at the same pressure in terms of its ability to make HP. I'm not yet able to report on what exact pressures these boxes attain, other than what the mfgs say. working on that part...



In my opinion that (strong low end) makes the Volumizer a bad stack with the VA duration box, simply because, like the Ramifier, it is too strong down low, i. e. too much when you stack with the VA. But thats just my opinion -- if you want lots of black smoke you should get it! Indeed, you can make black smoke with just the two VA boxes stacked, so imagine a boost-fooled ECM trying to fuel hard down low



Again, this is my opinion, but it appears that the EZ or Quadzilla or even Bullydog would be a better stack for the VA. they have omplimentary torque curves. that is, a pressure box that isn't so aggressive at the low end, but finishes strong. Ramifier could do that with a custom program. Or off-the-shelf Quadzilla, EZ or bullydog.



If you want to add timing and pressure to the VA duration box, there's always the Banks six gun w/o speed loader. I'm not sure how aggressive the Banks is at the low end. it may be too much as well.

Doug,

I was just looking at the Quadzilla website and they say thier box for the 03 does timing as well as pressure. I sent them an e-mail asking for clarification on that but if it's true I wonder if it has enough to help cool the VA duration box?

Edit:

Just checked your fueling box summary. Are you still running the two boxes stacked or was that just a test setup?

 

[lawdog]

DLeno,



I reviewed your summary several times before, very nice.

I have the Edge EZ and I set it on level "3". I have not towed heavy, only about 5500 lbs, and I am very pleased with the power and performance. Edge says that level "3" is 60hp and 200 ft lbs.



Have you done, seen, or heard of any EGT issues with this set up. I have an AMSOIL airfilter only, no other mods besides EZ.

Thanks

lawdog,

I ran an EZ on 3 on my 99 CTD for several years before I knew enough to worry about EGT, Turbo shut down temps and all the things I've learned here and never had any issues with it.

 

[DLeno]

yea I think what we've learned over the past few months is that moderate pressure (60HP) is your best bet for usable HP. if you live at sea level and you don't tow, you have an advantage. If you live in Denver and pull 14,000 lbs, you'r gonna have some issues.



In any case, drive by the EGT gauge, and add as much air as you can (intake and exhaust).

 

[SLinse]

Lawdog,

I have mine set on lvl 3 and towed about 13,000 lbs up some steep, long hills. I can go up them and not loose speed (65mph), but my EGT's can/have hit 1300-1400. I'm sure they will go higher. I am also around 500 ft above sea level. I like the box for towing. I do wish there were in cab controls, and had more for playing when empty.

 

[GWaggoner]

Gwoody as in IH8MUD?

 

[Greg Boardman-RIP]

Lawdod,

I have been running an EZ since they were doing the beta testing. My box has six levels. 0, 25, 40, 60, 75, 95. I have run this box on level 6 for almost two years now. I can tow in upward of 15,000 lbs and keep EGT's in check. But if I go to a WOT run uphill I can see 1500* no problem. The thing with the EZ is you don't have to go to WOT to maintain speed while towing. I see better mileage in the truck with the EZ installed. Lower EGT's, and better boost building. As Doug said, you must have an EGT guage and drive by it.

Scott,

The he was me and I'm none too happy about it either. Here's an interesting new problem with the C3. 2 also. It appears that since it also does away with the defueling in the off position that my "stock" egt's are about 50* to 100* higher on the top end WOT. Going to try an AFE next if I can't figure out the new BHAF that I located and then on to turbo's.

 

[SRadke]

I have the AFE and exhaust and both helped cool things down but not near enough for these duration boxes.

[Gypsyman]

Scott,

Have you started looking at turbos yet? BTW, what changes in driveability have you noticed with the TST?



-Richard

 

[SRadke]

This truck is still very driveable and very capable of towing. The beauty of this box is the range of adjustability. I told Mark when I went back for the reflash that I drove 2000 miles because I wasn't willing to drive the truck without it for the week it would take to ship the thing to him.



I have looked at turbos and there are a few options that interest me. DD's Jammer has good reviews and now I hear about a wastegated KSB-1 that is a direct bolt in. This one really has my attention.

[Gypsyman]

Thanks for the input, really appreciate it.

Thanks for yall's input. keep the progress updates coming as yall have successes and failures. I am looking to get a box soon, but really want to eliminate the stupid pilot injection (no, I don't care about the "diesel clatter", I am a 12 valve fan!!) I am looking to purchase who ever has a power adding box that will do this and is adjustable. Thanks for yall's input!

john

 

[DLeno]

nobody can eliminate pilot injection at this point, and I'm not aware of any one who is working on that. I think there may be work going on in the 600 world to eliminate the late (third) injection event.



the major box types out there are pressure, timing/duration, and duration. more detail here . if you want to skip all the verbiage, scroll down too the bottom and find the link to the comparative matrix. If you haven't seen that before it will get you started.



The last I knew, the Ramifier and Predator (pressure boxes) are the only ones not adjustable. The EZ is the only adjustable box that is not in-cab adjustable (it adjusts under the hood with jumper settings).

Thinking of upgradeing are we? Perhpas modifying the one you have?

[Dieselnut59]

Based on the comparisons listed, I like the "PDQ Volumizer" box, especially for timing/egt control and the low end punch and low boost fueling. I want some black smoke... just a little anyway!
