Engine/Transmission (1998.5 - 2002) Little Less Smoke?

[firefighter_2000]

Got an edge EZ, a set of 275's, and the boost elbow is turned to about 28psi. Im looking to build a little less smoke. Would simply turning down the boost help this? Im not doing any heavy towing or anything like that. Don't want to loose much in the go pedal, but for a little less smoke it would be okay.

Thoughts?

Thanks

Less boost = more smoke, so don't do that.



Have you tried moving the jumper behind the cover on the EZ? You can move it over a position or two to delay the extra fueling until a higher boost is achieved. I think the setting are something like 5psi (stock setting), 10psi, or 20psi.

The only way to get less smoke is the change the fueling. Boost has an effect on smoke but the less boost the more smoke the more boost the less smoke. The edge is designed to lower the fuel as the boost is peaked. It will fuel more till the boost is reached then plateau.

If it an old school Edge box, there is a jumper you can move. If I remember, the ez can add fuel at 3lbs, 10 lbs and 20 lbls of boost. Move the jumper to fuel at a higher boost level.

Edge EZ

This is a pic of the edge ez I have opened up at the end. It was made in 2002. Apparently not quite old school enough. IF I were to bump it back to the second setting, I wouldnt loose much HP, but what about smoke? Would that help in that respect?

Thanks

Craig, all the jumper does is determine at what boost level the extra fueling kicks in, the amount extra fuel at max boost on all three settings is the same. On my Diesel Dynamics box( a rebadged EZ) that setting you have is the low boost setting, which smokes more. Put the jumper on the left and try it, that should be the high boost setting. I'm sure someone here still has the manual and can help out, or call Edge and they surely can help you.

Older

So are the older EZ's different from the new ones? The new ones have three different horsepower levels selectable via a switch. Do the old ones produce the same horsepower level through all three jumpers just change at what times the extra fuel is added?

Don't know about the new ones but you are correct regarding the old one.

Jeeeeze. Remember the days when we were trying to make smoke? Romp on the throttle and leave the little ricer with the fart can muffler in a cloud?

 

[firefighter_2000]

I like that too

I LIKE to do that... But there just arent enough chances to do that. I live outside of town and work & drive in town quite often. I just kinda prefer to not have it smoke so bad. When I take off.

You're just under aired is all. Get a bigger turbo, preferably quickspool.

See my sig for build. Last emissions (July) was 3% opacity @ 40mph, 4% @ 50mph, and 2% @ 60mph. That's cleaner than it was bone stock.

Smoke is all in the right foot.

Have you checked to make sure you don't have any significant boost leaks? With just 275 injectors and a EZ you shouldn't be making much smoke unless you're romping on it. I put an EZ on my 2001 HO once and with DD2 injectors it wasn't hard to keep the smoke in check, DD2s were a lot more injector than RV injectors. What kind of EGTs are you seeing? Have you ever cleaned your IAT sensor or checked your MAP sensor?

Yeah, but wouldn't it be nice to shove your foot to the floor and get immediate power response without the cloud?



The stock HX35 is absolutely, positively more than enough turbo for the ~300 hp that an EZ and 275s give. That's where I"m at now, and it's pretty much smoke-free. Try the middle jumper and things should clean up.



Never heard of, seen, or ran a larger-than-stock turbo that didn't smoke more than that stocker on the bottom end. And twins would just be silly for that power level.

Well, then you would just be under fueled, and need to add some more. Oo. Viscous viscous circle.

If you like having to stomp the throttle to light off the turbo from every start and leave in a cloud of smoke, then yeah, I suppose...



I dunno... I've been down the big sticks and big turbo route for years and have recently returned to stock turbo and 275s. For around town, towning, and highway cruising (I guess, everything I use my truck for), the combo I'm at now has significantly more throttle response and bottom end power, and burns cleanly too (and added a solid 1 mpg). Wish I'd realized that several years ago.

I'm working on picking up a 24-valve and will be basically doing the same thing. . . smaller turbo, small sticks and mild box. Just to be an easy daily driver with enough power to be fun. Maybe all the BOMBers are turning into seniors :-laf

That is why I like the Pulse which I just upgraded to the New V2, you set the fuel and Boost ramps the way you like on the fly, no switches etc to mess with.

Could be. I know there was a push for a while to dump as much fuel as possible into the cylinders looking for that 900hp mark. 500 was considered a newb level and barely worth mention.



I opted for towing power and mountain driving rather than race. I found a great balance with my build. Hardly any smoke from a stop even with the edge comp turned on, and still have the ability to play a little.



The OP is running an auto, makes it harder to control the smoke from a stop and still get the truck moving. May have a boost leak somewhere as previously mentioned, or a flaky sensor.

 

[firefighter_2000]

Auto

True Im running an auto (ATS stage 2). What is the correct procedure for cleaning and checking the MAP & IAT sensors? I've got some time might as well give that a shot too. How is it you check for boost leaks? I remember someone telling how but I cant remember. I also just took the jumper and moved it to the center position. Less smoke for sure but still somewhat noticable.

Thanks

Loose the RV275's and go to a more efficient injector and watch your smoke become more managable. Also of note,some of the older EZ's had two more settings deeper in the box a guy could change also.
