Injectors

[KLockliear]

d90boy - WHOOPS, don't do that. The TTPM/EZ gets it's power from the rail pressure connection. If you unplug that, it also kills the connection to the MAP sensor and the truck will defuel. Here is a dyno graph of a truck with DD3's, our turbo and a Quad box turned off (the boost fooling doesn't work when it's off). The other graph is of the same truck with our TTPM on level 0.

So, make sure you go plug it in and set it on "0" if you want no power gain. This is why we put "0" in the box - because you can't just unplug the rail pressure plug.



XCX, we don't know what timing/duration will do yet - haven't tested it... but it should piggy back on the truck. How they work together remains to be seen.

Thanks for clearing that up, I got it plugged in now. Just to verify when looking at the adjustments the circuit board is on the bottom and the jumpers are on the left and middle pins of the set on the right. Kinda like this:

Correct.

What does not make sense to me though, is how can you dyno a truck with BIG injectors, and no electronics. I say this because 2gen's with 200+ hp injectors and no electronics when dynoed (such as my bro's truck) will not produce the HP the injectors put out, let alone it isn't even driveable with the box off.

I'll dissagree with this. Only because I know better. My truck dynoed 456hp yesterday on just injectors. I do have twin turbos but between them and injectors I made 250+ hp over stock. With the box on I made 651hp. I do drive it on the street that way but generally the box is on 1-1 to help control the low end smoke. All of this was on a new set of twins without doing any tuning.

I guess this was not very clear. What I mean is with just Big injectors the truck drives sluggish when compared to 100 HP injectors. For EX. when you put it to the floor the boost wants to climb really high suddenly but when it does the response (espeacially in overdrive) is sluggish because of the computer. The stock electronics are not as compatible with the BIG injectors as the 100 HP injectors are. Which is why the box would have to be on to measure the HP curve accurately as it goes thru each gear (espeacially overdrive).



Does this make sense, or not? Don't bash me over this cuz a lot of you are twice my age and know twice as much as I do about diesels.



Elite1 I think you got me confused, the 260 HP stock is my dyno result out of my truck which is a High Output.

 

[KLockliear]

Blake, what I was trying to get across is that WE rate our injectors based on what they do by themselves. Not with other parts on the truck. If they make 100hp by themselves, but with a box make 180, we still rate them at 100hp.



Other people may rate them at the higher number, but it's a deception to get you to buy. Bottom line for me is that if I install JUST the one product, will I get the gain advertized? With our stuff, you will.



From our own testing, I would say it's very unlikely to have a set of injectors in a 3G truck make 150hp by themselves with no box to add power (boost fooling is OK - boost will go up due to the power). If you or anyone else can prove me wrong at this time, I certainly say my hat is off.

 

[d90boy]

Keith I just want to clarify one issue. When you said you tried injectors greater than the stage 3s but they caused a misfire/stumble, was this due to the stock lift pump starving the CP3 or did you have your pusher pump kit on and the CP3 was just plain maxed out?

 

[KLockliear]

CP3 and rail volume are maxed currently.

 

[TShaver]

Keith, is boost fooling needed with your DD I injectors? Also, at what horsepower levels does one need to start thinking about an upgraded clutch (H. O. model)?

 

[XcumminsX]

can we buy a modified CP3 and rail?



Nick



P. S. Kieth i decided to wait on the airbox. I will just have to wait for the next turbo you guys are gonna make for the bigger power. I dont want to have to re-buy a whole airbox.

 

[Greg Boardman-RIP]

I have a set of DDIII's in the back seat of my truck. They will go in on Friday morning. I have the pusher pump from DD and hope they won't misfire. I'll post more on Friday.

 

[KLockliear]

Greg, you should have no problem. The only time the 3's will misfire is if the FP is low. As long as you are above 6psi, you're fine.



XCX, not yet on the rail/pump. The airbox we sell now works with the stock turbo, our current turbo and will also work with the next one.



TShaver - boost fooling is needed on the HO's with Stage 1's, Stage 2 on the other models. The stock 6-spd clutch will take about 350rwhp before being problematic. On an HO, you are at the limit with just a TTPM.

The reason large injectors feel sluggish is because you are putting out the fire (so to speak) when you romp on it with little to no boost. Basically you put in more fuel than can be burned with the available air. With smaller injectors this isn't as exagerated as it is with the larger injectors, thus better throttle response.



You can't dyno a 24v truck without any kind of electronics, unless it is stock or very mildly bombed, and expect good results. You do need the boost fooler feature of the box to allow higher boost without defueling but that function works when the box is off. So basically when the box is off it means the additional fueling the box provides is off.

Now that somebody finally understands what I'm saying, does any of THIS (Idaho CTD post) apply to a 3gen? Why, or why not?

 

[obie1]

Unless I missed it what was the answer to the question from badunit?



What's the max fuel pressure the Edge EZ allows?





This is a good question because if we have an EDGE EZ and the pressure pump on the 3rd generation fails (this is the right forum right 3rd generation) we need some ammo to discuss with the DC bunch.



I am sure there is a way to get the fuel pump pressures downloaded form either the error codes or somewhere there would be a pump pressure history. If the pump fails in the same pressure range as an unmodified machine then how can DC prove the EDGE EZ caused failure??????



It would be difficult

Could one use an Edge EZ with DD2 injectors with the stock turbo? Would this combination work?



Thanks,

I ran the stock turbo with DDII's and towed very heavy. Upwards of 25,000 lbs in tow. It will get warm not hot on a hill. Keep your RPM's under 2700 and you will be fine. You will need Exhaust and intake mods for sure. I am saving for the DD Turbo now.

I had two misfires tonight. WOT up hill at about 90 MPH (3000 rpm's). Fuel tank was down below and eighth. Just kind of stumbled for a couple of seconds then fine. Looks like I need to get a FP guage. HUH?

Thanks Greg. I'm working on the intake now and just bought a 4" straight through Mack muffler to put in as soon as weather gets more comfortable. I figure I'll probably go with an EZ first. Then maybe injectors down the road sometime. That should take care of everything.
