Drive by wire reliability
hmmm, where did I say throttle body. Drive By Wire (DBW) isn't just for a throttle body in case you didn't know that, well apparently you didn't?
The discussion was about reliability and dependability and I was just make a point that the technology has been around for a long time and the pedal feel, calibration and been thru real world testing since at least 1994.

HOLY DOUBLE POST batman!!!
Yah well its been in planes alot longer than that and quite a few other cars as well. The fact that Gm tried it then, maybe, but the diesel side has nothing to do with it. It does not control a trottle body at all.
and please tell me what you meant by THEM then. i take them as throttle body because that is the topic at hand, but then again maybe you meant them by controller....then thats right.

Thanks for all the replies, I've become a little better educated from this thread. I still haven't come to a conclusion, but I'm leaning toward one of two options:
1. Running the engine with DBW and removing the VVT, replacing the cam with one tailored to the 3000-5000 rpm band, and using a retuned LS3 engine controller. I'd rather use a cable TB, but don't want to tear into it to replace the reluctor wheel.
2. Going to a dual, selectable Megasquirt setup controlling the ignition and fuel, a cable TB, and replacing the VVT as above.
I'll investigate the reliability of the MS, but so far I see no problems. Unlike a car, an airplane engine really doesn't gain much from the VVT, since all I need below 3000 rpm is simply the ability to accelerate the engine from idle to 3000+ smoothly and reliably. I don't need anything above 5000 AT ALL. The engine will never see over 5000 and will live at 3000-4000 except for a couple of minutes each flight for takeoff at about 4800.
Believe it or not, I'm also considering using the heads and intake from a LQ4 (new) that I have sitting beside the L92. I'm guessing the power and torque in the range I need it will be at least as good (maybe better) than the L92 heads. I already have a cable TB for the LQ4. I'd welcome any comments.

how exactly does the drive by wire work i'm not familiar with them. I'm going to bue using an L92 engine out of an escalade with the escalade harness and ecm. But is there a different controller for the DBW or is it controlled by the ECM?
