Engine/Transmission (1998.5 - 2002) Old bucking problem with EZ/Will Smarty Fix it?

[Kent Kuykendall]

Does anyone know if a smarty will remedy the buck that I have with dd2s and an EZ. Does not buck with EZ unhooked.



Thanks

DD2's and EZ

I ran DD2's and EZ in my '99 for six years and no problem. I did encounter slightly poorer fuel economy. Sent injectors into DD. Two were below standards. DD replaced two and balanced other four to match. Turnaround time: one week. great service. Lifetime warranty with DD. I sold them to a member at a great price. I think the bucking is EZ related. Contact Edge. Good people.

I have sent first a ddufm back to dd and with the replacement still bucked. then traded it back in for a ddfm and still have buck. I have bought a fass and am going to try it even though I have ample fp. DD thought it may be a fuel delivery problem. Do not have a noticible buck unless I am towing. DD thought it was in the stock fuel curve and when it is multiplied by the box it made a difference but at stock fueling it was not an issue.



Any thoughts?



Thanks

Oh, I have a 95 gph FASS full meal deal, DD2s, Scotty2, EZ, Rips 4", and a trany upgrade



The FASS may be the difference. Sticks came frirst, EZ next, then the 4", that lead to trany issues :-laf some place along that, the Fuel pressure gauge didn't recover after a FF change, 8 at cruise <5 at WOT. That lead to the FASS system. Mo better now! Oo.

When I get my 95 gph fass on I will post results.



I do not notice bucking unless I am towing. DD assured me it was not a DD issue?><????????????



I am thinking if the fass does not take care of it I will try a smarty because from what I have read on here it is smother than the EZ set up.

maybe its your apps?

 

[Kent Kuykendall]

What is a an apps?

Nope, APPS does not buck.



I can tell you one thing though. I've seen and tested a few original ECM softwares that would do the bucking thing. A simple thing to do would be to have the ECM updated with a new software version. Maybe... .

Is this the bucking like you get with bigger injectors and lug the engine? My Mach II's have done it since day one. My fix? Dont lug the engine.....



I hear that its the ECM/Pump uses a certian amt of fuel for lower RPM. Well with the bigger/more efficent sticks, you get more fuel per "Pop". SO based on RPM..... the computer gets more than what it wanted, and cut back... . then its not enough and hits again... ... . then cuts back... ... . and so on... . is its a fair assumption?

If it is a software issue, would the Smarty software be smooth?



Thanks
