Anyone care to guess...

They are 3 pins. BAT+, GND and trigger. Trigger high to start dwell period, trigger low to cut primary current and fire the coil. I have a scope so I can get data on dwell as installed in the OEM application. This data can be used to populate the cells in the LS1 PCM coil dwell table.

Damn, the "French model" commercial just came on again.

Hey JEp,

how is the ECM swap/conversion coming along?

After reading this thread I realize I am truly a Z idiot.

A Zidiot?

You men keep up the good work.

Jep,

I thought all the LSx coils were 4 wire. Did you chose the 3 wire due to form factor? Is the 411 going to support a 3 wire setup? Sounds like you and Scott may have some collaborating to do.

Sorry for not posting any updates on this project. I went for quite a stretch there working 7 days a week and in the evenings as well. In addition to my day job, I was getting the offshore boat and two tunnel boats ready for racing season. Now that most of the racing stuff is done, I can get back to the forum and have at least some time to devote to the PCM project.

I'll post up all of the latest info within a day or two.

Thanks for the patience.

Jep,

Any chance u could provide disassembly of ALDL? Be worthwhile to be able to output params that currently are not.

Dom,

That one is easy to do. There is an ALDL data stream table. Each entry is the memory address where the value to be output is stored. The table is arranged from the first ALDL output word to the last. It just requires identifying what parameter you don't need, finding it's location in the table and then substituting the address of the data that you want to output in it's place. Once that's done, modify the data stream definition file for whatever scanner software that you are using (I use TunerPro) to reflect the name of the new parameter and specify units and scaling.

What year is your Black Rose? I can get you the table location if you need it.

Dom,

Look at address 08BB (if viewing an unstacked BIN file) or 88BB (if viewing a stacked one). You should see 80 00 80 01. These values correspond to the addresses of the PROM ID MSB and LSB, which is the addresses where the PROM ID is stored. Each additional pair of bytes will correspond to the memory address where the next data stream item is stored in memory.

Assuming that you are using the BPPA binary, the following table lists the address that the ECM retrieves the value from(column 1), the position in the data stream(column 2) and the description of the data item(column 3). If you view the values starting at 08BB(or 88BB), you should see the values in column 1(assuming that I didn't make any mistakes typing them in).
