This is my first post. I searched throught the forums and learned everything I could about connecting my Laptop to my newly acquired 86 Iroc - Z Camaro in just 48 hours. It was frustrating but well worth it. I even reported myself sick to work for two days and went to bed at 2:00am for two nights in a row. but finally managed to get data to WinALDL making my own adapter. Now I have lots of questions, maybe someone can help me with what you can.

Specs: 1986 TPI Camaro Iroc Z w/ 305 stock engine w/ about 145K miles. The only mods to this engine is a set of Hooker headers. The ECM says 16198259.

For those doing searches, this ECM is the one commonly known as "165". The connector I made is the first of the two shown in this page: http://w1.601.telia.com/~u60113744/s.../aldlcable.htm I'm using WinALDL software. You can find it here: http://winaldl.webhop.net/

Now for my questions:

1) I was able to connect at 160 bauds through the E pin on my car's ALDL connector. The M pin is empty. Can the E pin transmit at 8192 bauds as well? Or is this only for the ECMs that have the M pin?

2) Why are the MAF sensor readings fluctuating between 8.03 and 7.88 if I have the MAF disconnected?

3) What are the different $6E, $32B, $XX I keep reading about? Are these .bin files to burn into chips?

4) Why does it start really rough in cold mornings, but starts perfectly well if I disconnect the MAF? What should I look for in the captured data?

Any help greatly appreciated.

Also, if I can provide with any help just ask.

Yes, if the software will allow 8192 it will X-mitt it on pin E
Default settings

Those are the "masks" that are used for reading/writing the .bin files. Different bins were written with different "keys" or "masks".
Might want to check your Cold Start system to make sure it is functioning properly. You are looking for your BLM's, INT and knock counts, at least thats what I'd be most interested in when scanning a stock engine.

Thanks for that reply. I'll look into that right away.

Just a little more, 86 is $32
I would really advise going to the $32b at least if you plan on programming your own stuff.

Hey Blazer,

I have been working for the past six hours or so trying to get the ALDL connection working on my '86 TPI. It worked just fine on my friends '94 Z28 a few minutes ago, but I am having the hardest time getting it to do anything with the '86. The cable I am using is the MAX232 style that is powered from the computers serial port, and has a seperate lead with a 10k resister build into the cable for ECM's like the 165 that need it it can be found here. I checked it on my digital voltmeter to ground and it is at 10k, but I didn't trust it so I went and bought a pack of 10k resistors from radio shack to no avail. I was curious what you ended up doing to convince your '86 into giving up its secrets.

I used the first of the two diagrams shown here: http://w1.601.telia.com/~u60113744/...l/aldlcable.htm

The Max232 connector never worked.

The I downloaded WinALDL. I could only connect at 160bauds, though.

That was it. Good luck.

winaldl is nice, but ecm852 from craig moates is a tad better. I like it cause its a bit easier to understand.
