I know there's a big junkyard right around Jackson. I've got a friend from there. I'll ask him and get back to you.

hey nova any luck on the PCM?

No, I havn't talked to my buddy in a week or so. Soon as I talk to him I'll let you know.

anything come out of this?

hey, speaking of electrical engineers, my neighbor is one. He's doing contract work for NASA right now (building satellites). Maybe I could gather some info from him? This is really exciting and I wish I could do something to help, but I have pretty limited programming knowledge (C++, Scheme)

I've thought about all this before too. If we could make some progress that'd be great. It might be too complicated to try and decode what is actually in the stock computer so making a seperate computer might be a good idea then you could do whatever you want. Although all of the parameters to deal w/ could get pretty complicated too: cam postition, both crank position, O2's, rpms, speed, throttle position, IAT, IAC, MAP, ext...Another thing that might make it easier would be to intercept the signals going to the coils and the injectors, modifying them, then sending them back to the former mentioned output items, just like the DIS-4 modified the ignition. Maybe using a PIC programmer and controller type dealy...
I know basic c/c++ stuff and matlab. I don't know if it would be easier to find a curve fit for a set of points to profile the ignition and fuel curves or just to use a table. Does this spur any more ideas?

You can very easily do something like that utilizing Matlab Simulink and the Real Time Windows Target package and an I/O card. I know some companies use it to develop fly by wire control systems for aircraft which requires even more complex systems integration than a PCM.

It would be sweet to finaly be able to change computer settings on our cars. Could you take off the top speed limiter? I would like to see just how fast we can go.

Do you guys know if this would work on the 3.4's? It looks promising.

[StockV6Cam2]

TTT... anyone look into that Hal-tech computer?

I read through the site. I don't know enough about the PCM on the 3.4L to know if it would interchange.

[StockV6Cam2]

Well how about with the 3.8?

(i didnt get an attachment in my email, so im asking them if i did something wrong or if they forgot it. ill letcha know what i get)

You can use the E6k or E11 to control fuel and ignition. The price sheet is attached.

&gt; my 1994 3.4L V6 Chevrolet Camaro?
&gt;
&gt; Its a manual transmission car too. OBD I. i've been looking for a
computer
&gt; i could program myself, and you guys popped up somehow on my radar. hope
&gt; you have something i can use.
&gt;
&gt; thanks

hey that thing looks pretty cool, but not sure it will work. I was looking under specifications says stuff about different setups it works with all had distributors.

Might work for the 3rd gen guys.


I too really want to start getting inot figuring the computer out... for what its worth I have done some stuff with VB.NET no ace or anything but relatively familiar with the program.

I doubt the programming in a OBD-I computer would be to hard to crack.

Im looking at some code pulled from a auto 95 pcm and wow, alot of stuff...during xmas break I will play with it more, I think Ive found some of the tables ,but tehre is lots more..... good stuff....
