EZ jumper settings

[Gonzo 1066]

I just installed a EZ on a ETH with 275 injectors. The instructions show 3 jumper settings. #1 (as shipped ) The smokey setting, Maximum power. #2 Smokless acceleration with mild injectors. #3 Smokless acceleration with stock injectors. . Does the #3 setting deliver more fuel than the #2? I assume that the pump has to deliver more fuel with the stock injectors to gain the same amount that it would with the 275s? Comments?

EZ Settings

Gonzo, what did the people you purchased your EZ have to say regarding your questions?

I have not checked mine, but i thought it comes from the factory on setting three, not one? Anybody know for sure?, or should i open it up and check.

EMD, You are right, should come in #3 position (far right for jumper). As per my instructions anyhow. Had to check mine right after I got it just to make sure. Very easy to check. This last weekend, switched to middle setting on way back from K. C. MO. for 1 tank, just to check mileage difference. Unfortuneately it was at least 1 m. p. g. worse . Didn't take any longer than that to switch it back! Gotta love a little smoke anyhow!

Setting #3 is for stock injectors and larger injectors if smoke is not a worry.



setting 3, extrafueling begins at 5 PSI boost

setting 2, extrafueling begins at 10 PSI boost

setting 1, extrafueling begins at 20 PSI boost



The settings are there to allow you to match the fueling curve to your injectors so you can avoid excessive

smoke ( is that possible ??? ) in low boost situations.



The settings have NO effect on the fueling once boost is achieved only how soon the box begins to add fuel.



I may be off a little on the 5,10,20 numbers, but I had a LONG discussion with them regarding how this thing works. BTW, the boost elbow is a good idea. A little bird told me you could remove the OEM elbow and rubber hose by twisting and pulling the hose off the wastegate while the engine was warm. And then be able to reinstall it if you needed to return it to mother I wouldnt know...

Here is an old post I dug up from the end of july...



"The EZ does have a timing only setting. The settings are accomplished by

moving 1 or 2 jumpers from one set of terminals to another within the front

cover. Bottom line is there is timing only and three positions that combine

timing and fueling. This is to delay the fueling so as to keep the low end

smoke down to reasonable levels. " --- HVAC



This was in response to a post started by JyRO...

Now I'm confused... . Timing only??? I discussed with them the operation of the 2001ETH version, perhaps different versions function differently. I was told the connector that goes to the MAP sensor is how the EZ decides when to add fueling, and the other connector that goes to the Cummins computer is where the EZ can advance the timing. If i wanted extra fuel only and NOT change the timing I could NOT hookup the Cummins data connector and it would stay with OEM timing curves. This was confirmed by my mentor here on the TDR.



DOES ANYONE KNOW FOR SURE HOW THE DARN THING WORKS???

WEIRCUMMIN WHERE ARE YOU? HELP US OUT HERE.

Alright George,

This is how I understand it after Brett at Edge had to pound it into my thick skull. The EZ does not have timing only. The different settings are not there for when more fuel is added but to change the percentage of fuel added up to (I think) 20lbs. of boost. After that, there is no difference in the amount of fuel added for the 3 settings.



The map sensor connection is two fold.

1. to clip voltage and prevent the ECM from sensing over boost, defuel and set a code.

2. let the EZ sense minimum boost and start the extra fueling.



The data connector is where all of the timing and fuel curves are changed. If you disconnect it all that the EZ is going to do for you is act like a boost module.

WeirCumin Thank you. That is one of the answers that I am looking for. Up in the North East we get snow. Adding extra fuel on a nice snowy day makes smokey six wheel rooster tails.

Gonzo,

I was very confused following the thread Rob just posted about. The settings on the EZ are 20, 10, 3 psi of boost before fueling is increased and the EZ has NO timing only setting. I emailed HVAC but he did not explain how it had a timing only setting so I desided to go straight to Edge for the answer.



The following was the reply:

The EZ is just like you said 20,10,3 psi. when things happen. In regards to the timing only setting the EZ does not. Hope that helps give me a call if you have any more questions.



I run the EZ with 275s on setting two most of the time and one on longer trips and when towing. It only goes to three when a friend wants to play. One is virtually smokeless, two is ok and three I blow alot of smoke. ON 2 I can leave a standing cloud if I choose. I seem to be smoking alot more with the hot and humid weather right now.



I hope this clarifies things for you. It has only taken me since january to get a definative answer on this.

Sorry for the confusion... I just assumed since the info came from HVAC and that he sells Edge Products, that it would help... . I used the copy/paste so as not to misquote... .

Thanks for your help. I am not going to mess with it anymore.

 

[Gonzo 1066]

Thanks guys

Thanks, after rereading the instructions I was able to figure it out. It sure helps to get information from this site. I am going to try #2 first and see how it goes. I do tow 100% of the time with this truck so I dont want to overdo it.

I spoke to WeirCummins today.



I can assure you that the EZ modules that are sold by Performance Diesel are capable of timing only. I have posted about this previously.



Now, why would you want timing only? Would you purchase an EZ for just the timing? What do you expect from running the EZ in timing only mode?

 

[WeirCummin]

I have to concur with Nowel, why would anyone invest the money in the EZ and not use the available additional fueling.

Timing only.......

I set the jumper to timing only when I hook up to my travel trailer. I have PLENTY of power for towing with just the timing and the stage 3 injectors. The smoke was somewhat managable before I upgraded the torque converter, but now, (thankfully) the engine doesn't spool up to 2200rpm's before the load starts to move. Thats a good thing.

The jumper goes back to the max fuel @ low boost setting when I drop the trailer. I have found that I can't interest folks into joining the TDR when my truck just "smoked" everyone entering or walking thru the campground behind me. I'm not against smoke: I just save it for the weenie tired, body piercing sub-culture types.
