DBW vs DBC

[YAAPP]

I may have posted my question in the wrong place, if I did my apologies.

I apologize in advance if this has been discussed a ton, but I am a bit computer tech challenged. I am gathering the parts to do an LS3 swap in my 67 Camaro and a "friend" who may help me with the swap is pushing me towards a cable throttle body. He has apparently completed a ton of swaps and swears I will be happier with cable.

I have the Terminator X Max kit and am running a t56 Magnum. Opinions?

I researched this a lot with my swap and it mainly comes down to preference. Cable throttle bodies are arguably more reliable in the sense that the tb it self won’t really malfunction. The main failure point is the cable which can easily be field repaired or a new cable sourced on the road. A DBW tb will at some point malfunction or the pedal will and it will be a lot less easy on the road to source parts or limp it home. When it malfunctions, you will be in a limp mode and going home at 30mph

Thanks for the response 1985. The points you pointed out were also what I was told. Thanks

The DBW is a superior setup because of the advantages it offers. IAC is eliminated, DBW response can be tailored to your preference, voltage smoothing can be applied at part throttle cruise, DBW can be used in part with traction control, etc. Not a GM guy, but most OE's use the DBW components from the same few manufactures, and speaking from the Chrysler side, these parts do not fail. I have never seen a throttle body or pedal assembly fail in almost 20 years. I've see many get replaced due to poor diagnostics (i.e. vacuum leaks, etc.), but bottom line, DBW components are dead reliable.

Absolutely, there are advantages to dbw! For you average hot rodder they may not be usefulness though. There is no doubt that oe dbw parts are extremely reliable. That being said I wouldn’t say they don’t fail. I have replaced both pedals and throttle bodies (mainly or all Gm) over my 15 years as a mechanic. No come backs for bad diagnosis either.

This is what I am being told, plus the feel is superior, whatever that means.

the feel thing is just a delay in the response to input. You can feel it in some modern cars. It’s not the end of the world, but can feel a little disconnected. It can be tuned out, but I believe there are some downsides to that, but that is outside my lane
