There's a comment I hadn't heard before...why does safety dictate removal of the DBW? I was planning on using it.

The drive by wire is of zero concern is a factory ECM is used. 99% of the LS motors we sell and install use a factory / GMPP ECM.

As Pantera mentions, I too have concerns with aftermarket ECMs and DBW even though some aftermarket systems do have DBW capabilities.

Thanks Frank. One of these day you should write a book...:thumbsup:

DBW=Drive To Death
 

At the OEM level, I know about 9,000,000 reasons why it was a BAD idea !

Good info Lance!

Lance - please exlpain that one. I'm sure you have experience, so please share?

I always thought LS3 + VVT = L99? What's the difference between the two?

DBW is the way to go.

How long have the OEM's been using DBW?

Other than Toyota trying to kill their customers, it's been good.

DBW has been treating me good so far in my DD. I will say that tuning it isn't as hard as I expected. It's nice not having to worry about the Idle air circuits, plus the PCM can easily modulate throttle so it can compensate for many drive-ability issues you see with a cable operated TB. You tell it desired air flow and it does the rest.
From an aesthetic standpoint; It also looks much nicer sitting in the engine bay.

The only issue I've ever had is a wiring issue caused my truck to go into limp home mode. It essentially sets the throttle at about 1500 regardless of pedal input. It's a little bit of an inconvenience, but a necessary evil. At least it lets you drive it back home.
If I didn't already have my PCM and harness I'd easily switch to DBW.
