I got some of my stuff in today. Harness is being made, and should be here at end of march. I wound up going with the mono blade, as they were out of 58mm and I figured if they were the same price, why not. The throttle is noticeably lighter than my BBK coming off of the car. I cant wait to get this engine running with this setup.

I also noticed how much lighter the LS1 PCM is.

Anyways here are the pics. OBTW I have way too much into this build at this point, and should have probably changed platforms. I on the other hand really wanted to see my built LT1 live, and I think it will.

Yeah I ate my steak and stared at it and asked it if it wanted me to caress it.

Is that a Toyota gas pedal assy? Don't forget to upgrade the brakes.

Looks good! First person I have heard of doing the drive by wire on a 4th gen. Far as the plat form stuff goes, I could have been on my way to a C6 by now.

Is the drive by wire conversion required?

Got the pedal installed. I wound up using wood to come up with dimensions, then welding a bracket. The bracket works off of a pre existing bolt going into firewall. I also wound up drilling out part of the upper pedal assembly bracket running some all thread with a nut through that and then stacking metal bar stock that had been drilled to appropriate size. After all that the CTS V pedal bracket sat level and in a good position. (I also drilled this to accomidate the all thread and put a nut on the other side) I am still going create a triangular reinforcement to the existing bracket to make things even more stable.

Hopefully you just got all that.

As of right now the pedal feels like it is in a great position and natural to my foot, (it was a big concern to me) It is very sturdy and almost done. I am so pumped because I think startup is going to be this week or weekend! I just need to bleed brakes and do a little more adjustment on the strange strut springs height, and its time to see if all my hard work has payed off.

very trick setup, i cant wait to install my LS1 PCM. Not a fan of DBW though, ill stick with a cable!

Enough to show you really love LT1! I could have easily went to LSX with the extra cash I spent on my 24x setup. Its about an extra 1k in parts, on top of the 24x setup.

I know there has been one other setup installed other than efi connections engine on the engine dyno. (it is in a 3rd gen) From what I know I am first to install this into a LT1 Fbody.



Drive by wire gets rid of a lot of idle problems since the computer takes control of the blades vs a valve to control idle. I am running a larger cam, so I figured this would relieve some of the headache. . DBW only seems to mess up in the toyotas! From what I understand you get the blade open faster with this type throttle.

lol aint that the truth!

for dealing with an idle issue that sounds like an excellent solution. I know that it is also an excellent solution for working with cruise control, and eliminating the need for a system capable of defeating the throttle spring [requires significant electrical power].

However, Ive heard several people say DBW is faster, but i don't understand at all how that is physically possible. Seems to me the only way you could get any lag with a throttle cable is if the cable was stretching like a spring (aka dynamic loading). Throttle cables are static loading, therefore they should be opening the TB at the exact same rate your foot is moving. Unless DBW has some sort of "advancing" system that can be added in, a cable is not going to be beaten.

I owned a 99 V6 camaro with a stick and factory DBW. Im sure that system was not built to the same par as this one (not really a performance based engine) but it had terrible throttle lag. When speed shifting at full throttle, it would consistently 'negative chirp' the tires as if i were engine braking, even though my foot was already to the floor. Not saying I would expect this issue with yours though. Ive driven many corvettes with DBW and never noticed anything of the sort.

I think you're right.

Cannot wait to get my LS1 pcm tune now...

Here is a small idle clip that I took on my first startup!

Not getting any throttle response though even though the blades on the throttlebody are functional. I think it has to do with the tune, but still checking into it. I got a base tune to get engine running, and will be taking it to get aligned/dyno tuned after I get this ironed out and broke in.

I need to readjust lash and re-tighten header bolts now.

Glad to see she fired up! did you have any other problems with the setup?

I recall renting a new Express Van last year about this time and the throttle response was terrible. For a 6.0L engine, that van was very slow on acceleration. We logged data with EFILive and found a very "lazy" tune in the ECM. The commanded spark advance was a huge culprit.

Now my Silverado SS (also a 6.0L engine) is very responsive. My S10 (V8 with 03 Corvette electronics) is also very responsive.

Don't let the "lazy" calibration work from GM deter you from drive by wire. Not only is that the present/future of throttle control, but it has its benefits when embrace it and make it work for you.
