"The E67 is the high-line controller in GM’s new family of three
engine control modules (ECM), which will direct nearly all the engines in
Powertrain’s line-up. It features 32-bit processing, compared to
conventional 16-bit processing, with 32 megabytes of flash memory, 128
kilobytes of RAM and a high-speed CAN bus. It synchronizes more than 100
functions, from spark timing to cruise control operation to traction
control calculations, and it will work in vehicles with different generation
vehicle wiring systems, or LANs."

I just bought one to take apart and tinker with. It's supposedly the
most advanced ECM in GM's lineup. It can handle VVT phasers, DoD
solenoids, and all kinds of extras. There are many applications and
calibrations for this ECM, including I4, V6 and V8. Considering mine just cost
me $60, I think this would be a great base for a cheap aftermarket
controller.

Is anyone interested in working on a project like this?

I don't have the electronics skills for such a project. But I'm definitely interested in the final product. IMO, an ECM capable of running any engine you decide to stuff into your Fiero would RULE!

Edit to add: would this type of ECU allow on-the-fly tweaking/tuning?

It most definitely should have the bandwidth to do it.

I am interested in it for sure. I suppose you will be flattered that after talking with you about your Northstar kernel and how the proverbial average Joe can do it that I want to program for GM after I get my EE degree.

What sort of things specifically have you in mind for the project and what engines?

I'm really curious as to how they plan on utilizing these new boxes. They are kinda cute compared to what I am used to seeing. What I am really curious about is how many different ones are they going to make. Perhaps one part number for most cars??? If they keep it down to just a couple of units, I would invest some time into their inner workings.

Lets see, how much OBD 1 Inventory do I have anyway?

Thanks Ryan
.
No trans controlling in this ECM correct?
Is that why it is called an ECM and not a PCM?
You will need a GM High Speed LAN trans controller if you use an auto correct?
This will open up may more trans and engine combos correct?
.
GM has a smaller version of this controller that are used also. By smaller I mean less power and options

Imagine megasquirt to the nth degree.

1) You don't have to assemble anything
2) It will work with ANY engine.
3) Tuning capabilities of a GM computer - i.e. infinite parameters to change
4) Cheap - $60... 1/4 the price of megasquirt
5) Once someone has tuned it for an engine, that tune file could be released and anyone with that combination would just have to download it to their computer.

It's like getting a $4000 aftermarket EFI package for $60 + misc parts and time.

Don't know. I don't have access to any wiring diagrams past 2000

But it makes sense that it is just an ECM from their description.

Sounds like the way to go for future swaps. I will have to start looking for one of those nice supercharged N*s

So, are you rallying support for future financial endevours, gauging interest, or looking for programmers?

How featureful are the ECM hardware and controllers? How many inputs and outputs are there, and how many does your average engine need (Northstar, Series II, Ecotec, etc)?

Thanks. Just take a look there to see the kind of I/O it has. 2 MAP sensors, 2 IAT sensors, e-throttle control (which means 3 TPS inputs), 4 heated o2 sensors with heater control (PWM), 4 cam sensor inputs, 4 VVT phaser solenoid outputs,sequential v8 fuel injection, "coil on plug" ignition ....

How does one get this information and is it "illegal" to give it out?

Any luck with getting the pinouts for the 2.9L V6 Caddy diesel?

Makes me all warm and fuzzy inside: http://www.carkeys.co.uk/ne...7/march/07/12615.asp

If you want to program one that can run a series II 3800SC with a manual tranny I could make up a harness and try it on my next manual tranny 3800SC swap. Sort of use it as a test to see how it compares to the stock PCM. It would also be very helpfull for use in an LS4 swap into a Fiero but it would really help if it could control the 4T65E auto tranny as well. Dan

So, I asume the first step is finding easy ways to get programs on and off of these pcms, the software can follow from there.

Arent the OBDII controllers soldered to the board? I would assume the same design would follow through to these newer ECMs. Arent they normally reprogramed through the OBD port?

My understanding is that CAN based setups are MUCH easier to reprogram than previous OBDII hardware. We're back in the early '90's when getting the program off the computer was as simple as pulling out the EPROM.

Ryan, or anyone who wants to access repair and wiring data, I found not only the Chiltons database but the Alldata repair database access at my local library. The chiltons can be accessed from home, but unfortunately, the Alldata database can only be accessed from a library computer because of their agreement with Alldata, but it is available. Haven't really looked to see how much 2000+ data is in the database.

This ECM sounds like a very good option. Can you give us the ECM form factor, connector data, and manfacturer of the CPU? That would enable us to look up the factory data book and assembler coding.

Pretty sure the CPU manufacturer is going to be Motorola under the 68xxx architecture.

Aha! Sorry, my question was answered in AJ's post. It's a motorola controller. That is going to make things easier, motorola pretty much keeps the same assy encoding from cpu to cpu, why reinvent the wheel? Much of the same assy language programming works from their early 6502 all the way to 68332 and beyond. Wonder if the L67 could run an Apple operating system? Perhaps add ram to it? Say, a touch screen that communicates directly with the cpu? Should be able to run the engine controls at the same time, no problem.

I am doubting it has much along the lines of a video output controller But it does sound like there are a few inputs we can use, outside of normal sensors.

My biggest thing I want is a nitrous controller, o yea!

Interesting idea. Perhaps a peripheral port that will output data and allow tuning on the fly instead of having to carry around a laptop?

Yeah, that's the idea, a wholly contained PC/ECM system, just like the early Apples ( but the monitor would be optional. ) All U would need to do is program an apple GUI application for the interface to the engine control routine. In fact, it should be fairly easy to get some RGB signals to interface with a monitor, maybe be able to also interface with a HD, and with all those solenoid, sensor and other interfaces available, only your imagination would be the limit. Wouldn't be just for Fieros, could be for any swap, and for the price....it couldn't be beat.

Yes, you did. Can you access the programs as files on a hard drive, or are they in a protected or proprietary format?

The 12603530 "E67" ECM (click for extra huge pictures):



This thing is tiny, it's the size of a hard drive.





They did NOT design this thing to come apart. They used glue everywhere instead of screws. It appears as though they installed the connectors (with glue), then the PCB (with silicone), then soldered the connectors. I don't think this is coming apart without some damage. I'm trying to figure out a way to minimize the damage....

Note the only chip on the back side is the MC9S12C32:
* 16-bit HCS12 CPU
* Multiplexed External Bus
* 32K byte Flash EEPROM
* 2.0K byte RAM
* 8-channel Analog-to-Digital Converter, 10-bit resolution
* 1M bit per second, CAN 2.0 A, B software compatible module
* 8 channel 16-bit timer module
* 6-channel 8-bit Pulse Width Modulator

I think that might be pushing it. As other control modules are added, valuable I/O pins will be required. I'd recommend a USART bride to a separate controller which trasceives data to and from the ECM and writes to a screen. Maybe, maybe not. Technology has come a long way, but even the Reatta had to have an Intel 8080 to interface with its screen.

Hey Ryan, I thought you said it had 32-bit processing, or is that just its hardware multiplication module? The hardware modules dont seem to be complicated if thats all there is (although I am not well-versed in CAN), but what the hell is a 8-channel Timer module for?

Well I was able to desolder all the connectors, and pry around the outside to pop out the main board.

Now this is pretty surprising....... GM has stopped "rebranding" chips. Or perhaps that's something up to the manufacturer once GM stopped building their own ECM's? At any rate, parts are very standard...

Processor is a MPC565 from Freescale (formerly Motorola)

Datasheet:
http://www.freescale.com/we...mary.jsp?code=MPC565

Onboard RAM is IS64LV6416AL:
Datasheet:
http://www.issi.com/pdf/64LV6416AL.pdf

Onboard Flash is Am29BDD160G:
Info:
http://www.amd.com/us-en/0,..._2048%5E7466,00.html

Pictures of the board reverse:




It's amazing how far they've come....... 4 chips on a tiny paper thin board.

Oh, almost forgot... Searching for the flash, I stumbled upon a app note about interfacing the AMD flash chip with an MPC56x CPU... http://www.amd.com/us-en/as...tech_docs/25267a.pdf

Thats interesting. What is the other 16-bit processor for? Is it to interface between the CPU and engine using its hardware peropherrals?

Hey was it full of boogie gel?
.
I have a SDM open currently.
I also have a ABS/TCS open trying to cheat a code out of it.
.
.
That is something I wish you could do.
.
Example #1
PK III .... I used a DEI 555G PassKey III immobilizer bypass module. The 555GW uses a unique auto program sequence to learn the secure code from the Key Cylinder Module and repeats it when remote start is activated, eliminating the need to leave a key in the vehicle.
Basically I have a power, ground and Data wire connected to the module. To get a code I connected the module to any PK III cars DLC. The DLC has power, ground and Data. I had to ground one more wire to put is in the learn mode. The LED flashes and then the code is learned in the bypass module. I use a fresh PCM so it learns the first code sent out on the Data line.
.
The bypass module knows the type of code to copy.
.
.
Example #2
DEI universal Data Bus interface
I can not be sure of the model #, but it may be a 1700G.
I stopped in at the local install shop just down the road and talked to the installer about this unit. He says he needs to set it up with a PC. The setup is needed for the application.

This unit can be used to learn the code for many options all on the DATA line. Just one wire for all. It can be used for Passkey, Door locks, Power windows, Power sliding doors, heated seats, HVAC settings, Radio settings.
.
He connects it to a PC and then sets it up for you. So he need to know Year, Make, and model to set the module up to look for the Data Bus Code. He also told me he needs to turn on the functions I would want. An example of a functions being all the windows go down by using the remote.
To learn the code to run the windows, door locks or what ever you want. You put the module into the learn mode and then the module copies it.
.
.
Ryan can you build a Module to Learn state of health codes. If I could get a "bypass" module to look for and copy the codes I want it would be great.
I may need up to 10 SOH codes learned.
.
.
I hope you could follow my rambling

A datalogger would be trivial for what you are wanting.

I would use a microcontroller that would have an interrupt on a pin toggle that would start or restart a timer to time how long it takes a pin to change. After the line goes low for some time, you can assume the transmit procedure is completed and data logging will be complete. An RS232 cable would be plugged into a PC and it would transmit the toggle times and the PC would output some information that will tell you some information you want to know.

I suppose a mode can be set to take that information on the controller and replay it through the data line to see if it works.

$60 investment Hmmm. I am all for it especially because it is out of your pocket.
.
.
.
I know the is an ECM and not a PCM or VCM.
An ECM is an Engine Control Module VS a Powertrain Control Module or Vehicle Control Module. This means NO Trans functions.
Since Ryan has been Soooooo helpful I will post some info for him.
.
This is for the trans controller. just imagine $40 for a trans controller to work on GM High Speed LAN.
