Engine/Transmission (1998.5 - 2002) Edge e-z adjustments

[BarryG]

Rattler:

I ran mine on the 3rd position most aggressive for several months. I had noticed a decrease in mileage. So I moved it to the center setting. After doing so I noticed a little decrease in power at takeoff but once the turbo was spooled up to approx 10 psi or so it was the same (which when you hit the go pedal doesn't take long to hit especially if you are already at 5 or 6 psi). My mileage came back and then some from stock. I also noticed a definent decrease in smoke at takeoff. I dont race from light to light and rarely unless really needed to do wot takeoffs so moving the setting helped me at least in the mileage dept. I still have the full power where I really need it passing etc.



PCarlson: edge told me (now this was several years ago so it may have changed with subsequent models) that the settings for the EZ were 20psi, 10psi, 3psi, no flame intended just passing what they told me.

I called Edge Tech Support last week. I was told that putting a jumper on pin 1 and 3 would DISABLE the timing advance and just do fuel. However the tech did not know what fuel level the 1 - 3 combo translated to (ie 1, 2, or 3 level in that position). I would be curious to know what fuel level that would be at, in that position.



He warned that performance and especially mileage would suffer if I disabled the timing advance in the Edge. He said the timing advance is 100% OK to use with my DDII injectors or any injectors for that matter. I talked to Diesel Dynamics also. They also reassured me that Edge EZ in any of the settings WITH the timing advance is perfectly fine and in fact made for a very good combo with the DDII's.

Can anyone confirm this? Anyone from Edge products on here? Been hearing some rumblings from some that the Timing portion of the box might not be the best for the ETH????

So you say you have a switch on your EZ that lets you control the jumper settings remotely. Sounds like somthing I'de like to try. Which of the jumper leads are common and can you switch settings on the fly?

It would be nice if we could find out if it's possible to turn an EZ into a TTPM with the addition of another jumper. If so, it would also be nice to know the equivalent fueling settings/jumper positions.

Well I called Edge's tech support and got that information. As I said above he told me putting a jumper on pins 1 AND 3 disables the timing, but he didn't know what fuel setting that translated too.



It would be good information to have, but I would like to KNOW more about what that setting actually does, besides supposely disabling timing.



Maybe another phone call to them would yield some results?

 

[Muleskinner]

So my question would be, with the stock transmission, would I be better to switch to one of the settings that would require more boost and throttle before fueling begins to better lock up the converter, or to leave it at the factory setting?

 

[Mingoglia]

This is definitely for the gen 2 trucks and not the 3?

WIth an Auto I'd use 1 or 2. With mine on 3 the bottom end hits HARD as hell. Makes it fun to drive when it's wet. I might try to call them this afternoon. I'm hearing reports on this site where the timing function could be leading to deaths of piston number 6 and head gaskets on ETH from high cylinder pressures. Can't prove it but I don't want any part of that... The sky is falling... .

Let me know what you find out. I had to call edge the other day and spoke with Jason. He told me the stock setting is for stock injectors. Setting #'s two and three reduce fueling only at lower boost for folks with bigger injectors to reduce smoke. He said all of the settings retain the same amount of timing increase over stock.



I took the jumper off of #3 and put it on #2 today. Felt flatter off of idle, but strong when I punched it a bit more. I pull a large horse trailer that weighs about 8000 pounds with my animals. My main concern is not to blow the trans with the box. I asked Jason about it the other day and he assured me the EZ was designed for towing. I hope he is right.



You are right. I put on a Jardine 4" system two days before the EZ. Not much seat of the pants difference than the stock exhaust. When I put the EZ on, it pulls like a freight train at part throttle. I can pass cars at 1/4 throttle like it was wide open before the EZ. What a difference.



I tried the Super Chips Tuner prior to the EZ. The power increase was not even close to the EZ. Nice unit, but not what I thought it would be. Sent it back for a refund. Although I will miss the speedo change ability.

Muleskinner,



Look at Superlift's Speed Re-calibration box. It's straight forward to install, and has infinite adjustability to get the speedo dead on. It also helped my shift points a great deal with the 315's.

 

[Muleskinner]

You say it helped your shift points. Does it actually change the trans shift point through the computer?

 

[Udaloy]

I think so. The vehicle's speed must be used in the computer's calculation as to when to shift. With 315's, my speedo was 10 to 11 mph off, so it makes a difference. I know that without the box, the truck was running third gear out to 2500-2600 rpm before going to overdrive on the acceleration ramp. Now with the box, it shifts to overdrive around 2000, given a normal throttle position (not WOT).

 

[JSandusky]

I'm certainly no transmission expert, but I've been told by an expert that our trasmission 3rd to 4th shift in completely controlled by the ECM, as is lockup of the convertor in 3rd or 4th gear. However all other shifts are done with tradition methods in the transmission, using line pressure's. I'm sure the ECM uses speed input to help determine the shift into overdrive and lockup points. I would bet it also looks at other sensors too, such as RPM, and throttle position.



What doesn't make any sense to me is why a gear or tire change would change the RPM of the shifts. The spedo to tach ratio ramains the same after a tire or gear change, even though your real speed is different. I think the only difference should be it shift at different REAL speeds. The speedo and tach should stay close to where they were after a gear or tire change, as far as shift points are concerned.

 

[Udaloy]

I'm certainly no expert either, but if the ECM thinks the truck is traveling at 55 mph, when it's actually traveling at 65, wouldn't that make the rpm's higher at the point it shifts? All I know, is this is how it acts.



The Tru-Speed calibrator has an A-B switch in case you run different size tires. In position A, it's set for my stock tires, in position B, it's set for my 315's. Every time I try it in position A, I get the same results: higher rpm's at 3-4 shift.

What you say makes sense. The computer can only read inputs to it. If your speed is faster than what the input from the sensors are telling it, then the shift points will be artifically prompted.

I spoke with Jason at Edge this morning. I wanted to hear it from the horses mouth how the jumper positions on the EZ affect fueling and timing.



Per Jason, timing is advanced the same on all three jumper positions, only the rate of fueling changes. He assured me the default factory jumper setting should not make me loose my trans.



So. I will toss the coin and keep it where it is. Hell it sure is fun to drive like this. Pulls like a freight train in the lower RPM ranges. WOT from 0 to 90 feels strong, but not anything ground shaking. I find the low end part throttle torque is this box's performance advantage. Oo.
