Engine/Transmission (1998.5 - 2002) Bucking went away with Smarty

[Kent Kuykendall]

Thought I would follow up and report my experience.



I have always had a bucking when under load with any type of fuel/timing adding divice. It was not evident unless towing trailers.



Here is what I have found.



With the smarty on fuel only I have no bucking.



When on timing settings and towing I have bucking.



So when I tow I set it on mild catcher and truck runs flawlessly. Better that it has ever ran.



Truck will also build more boost than with other non pump wire tapping devices that I have tried.



I first installed a Fass thinking that it may have a fuel delivery proplem. It did not cure any problems. However I think the truck runs quieter and smother.



So if you are on the fence with this type of problem the smarty took care of my problems. I can't say it will help yours but it did take care of mine. . Great product.

Too much base timing, several of us are affected by this. I placed a potentiometer in parallel with the IAT sensor to fool it into pulling out some timing. It's especially noticeable in colder temperatures. With my EZ I don't have access to a fuel-only program and I believe the EZ has more aggressive timing than the Smarty's w/timing programs. I was fine until I added bigger injectors which add their own measure of timing advance. Combined with the EZ it was too much and would buck when pulling. IAT fooler fixed it At least until I replace the EZ with something else...
