3.4 Camaro ESC module needed.

[NoMad]

Like the title says I am hoping someone who did the 3.4 conversion has a knock filter hanging about from post swap parts. I need it for the knock sensor on the new computer.

For reference the part is: Esc Control Module - GM (16171749)

Out of curiosity, does this eliminate false knocking?

[NoMad]

No, I think this is what interprets the signal from the knock sensor and feeds it to the ecm. Apparently it is a required part for this swap to make the knock sensor work. False knock is still an issue I am told.

I don't know of anyone who has run a knock sensor with a 3.4 7730 conversion unless f85gtron has.  I seem to recall that he moved the sensor out on an extension because the 3.4 was a noisy engine and gave false knock readings.  You can PM him and ask.

If nobody has one, search for that part # on eBay. I see them for $17 and up.

He does.  The extension has an angle.  Our engines are noisy, so have lots of false knocks.

Ended up driving to Lawrenceville today and buying a camaro 3.4L pcm just so I could grab the esc out of it.  But one thing sorted.

Hijacking the topic: When people put a 3800 in a Fiero, the usual practice is to also use the 3800 electronics (ECM/PCM, etc), instead of trying to make it run on Fiero electronics (or even the slightly newer 1227730 ECM). Question: Why isn't the same thing done for the Camero 3.4? Wouldn't it run better on the Camero electronics?

The Camaro and Firebird 3.4 is a sequential fuel injection system.  To run the engine in a Fiero in that manner, a complete new harness would need to be built to convert it from the multiport batch fire system, even with a 7730. 

I kept the ignition control module and coil pack and the digital EGR valve from my 3.4 so that when I install the 7730, I don't have to try to find it in a yard.  All the sensors of the 3.4 were left in place so that they are there and ready, and they help prevent leaks.  I have no idea where this electronic spark control module is located or what it looks like.

The esc module is a small module that plugs into the pcm under the cover plate on the ecm itself. It is needed to make the knock sensor work properly according to the Dynamic EFI folks. 

Only sensor I am now missing from the original 3.1 donor motor is the crank position sensor. I plan to locate and properly wire one as soon as possible but since it isn't needed to run the distributor ignition it isn't as critical for me at the moment.

I believe a lot of it has to do with the people doing 3.4 swaps wanting it to remain otherwise stock - or at least stock appearing - for the benefit of the smog referees or show judges.
Also, at one time, that was all that was readily available. The 3.4 was bolted in with all the Fiero stuff, including the stock injectors. The fuel pressure was "tweaked" to stop it from running out of fuel at high RPMs, and they called it "good". Nobody knew how to tune, and anything ECM related (especially wiring) was akin to sorcery and witchcraft.
Now, people are running Northstars on 7730s and LSx PCMs. Remember how "untouchable" those things used to be.
In addition, Fieros are now old enough to be smog-exempt in most states, so the cosmetics don't matter nearly as much.

Interesting.  I asked this same question 4 times in as many years, and got no answer.  You received 2 good answers.  I guess it needed the right person asking the question.

Anyway, the sequential injection also requires that the cam sensor be installed.  I think it could still look stock with the injectors wired for sequential fire.  Someone would have to be picky to notice.  The batch fire would seem to waste fuel.
