Engine/Transmission (1998.5 - 2002) timing boxes

[ASimpson]

sorry to ask a stupid question butwhat does changing the timing do to these trucks? i see posts where people say they are using edge and other boxes for timing stacked with other boxes? just wondering thanks adam

A negative view on stacking

Adam,



Stacking refers to combining electronic performance modules, or boxes, for high levels of engine output. This is a hot rod trick.



A popular 'stack' is a timing box with a fueling box, i. e. an Edge Products EZ (famous for it's low rpm torque boost through an aggressive advance in diesel ignition timing) with a TST Products PowerMax fueling box. The TST box is famous for it's ability to give the VP-44 injection pump copious amounts of fuel ONLY, no timing.



These two products together perform as if they were manufactured together, instead of in Utah and southern Indiana. Horsepower and torque are DRAMATICALLY increased and come on hard and EARLY in the powerband. This is the Edge timing box. It will give you off idle smoke and fuel in the low to mid rpm range. The timing will spool your turbo sooner and the rear tires will break loose as you build boost sooner than a stock rig will. Behind your bumper you will notice a giant cloud of soot like a big rig leaving a light. A grin will light up your face as you approach 1700 to 1800 rpm... ...





... ... and then your fueling box begins to dominate the fcm on your VP-44 fuel injection pump, it will piggyback a SECOND fuel pulse signal on the ECMs original injection solenoid signal and hold it closed a bit longer to cram even more diesel into an already hot and burning combustion chamber.



Now you are in the upper rpm band and your transmission is in overdrive and you are approaching 100 mph, 38 psi and 1400 EGTs and you gotta back out of it, or you will turn your pistons into a liquid but MAN! THAT WAS FUUUNNN!!

WASN'T IT??!!



Or was it? While you were having your little joy ride, you broke two teeth off your ring gear and cracked your spiders, twisted your input shaft on your transmission, your clutch wont hold anymore and you boosted your turbo out of it's mapwidth and the backpressure your boxes made actually pushed your headgasket OUT from under the head!



And you still gotta make payments on this bad boy.

ok i have a blue chip apb its fuel only so should my next mod be injectors or find an edge ez box for timing.

The EZ does pressure only. I have the TST/EZ stack. EZ for pressure and the TST for timing and duration. I think one of the Quad boxes does all three.

 

[wtfd6]

the tst does fuel only and the ez does timing. i have the tst and love it.

 

[ASimpson]

ok those last two posts sorta contradict each other. i was under the impression from all the posts ive read that people use the ez for timing ?????????????

 

[ThrottleJockey]

Those two guys are talking about two different generations of diesel injection systems. The VP-44 electronic control and the newer common fuel pressure rail injection.

That's for the common rail...

 

[ASimpson]

so all this being said should i look for an ez or just go ahead with injectors? just asking opinions. thanks adam

Leave it stock! that way when it comes time to upgrade or if you wreck it you wont have all sorts of money in it. Your truck will do great stock and last longer!

Were Already Past The Stock Point.

 

[SKneeland]

an EZ would be a nice addition, but you might want to check out a smarty. it can do the timing like the EZ, but also some other cool stuff as well.



if you want a real kick the in pants feel add some injectors at the same time. mach 1. 5/2s would probably go well with this combo and stock turbo. you should gain some mpg from this mod as well.

i only know facts about second gens. i know the tst for third gens does timing. but i have first hand knowledge on second gens only.

I have a edge comp and would like to stack it with a smarty. Should i use my comp and just not use the timing feature of the smarty?Or sell the comp and put a tst pm3 or some other fueling only box on and use the smarty to its full potential ?How much power increase would this have?Thanks Jason

 

[Bob Wagner]

tst or bc/smarty is a better stack

 

[monkeyman]

Owning a Cummins is like owning a Harley, I don't know to many people running a stock Harley either. I am running the Smarty, A comp Edge stacked with a TST Comp. But I would not do that as a option on a stock truck.

how are you stacking 2 fuel boxes?? and why??

i've got the EZ and haisley box stacked... works well together, i'd sell my ez though as i wanna p pump
