I need to have the ECM inplace and connected to the be able to read out of the CCM correctly..
After reading through the post and fixing some Arduino code, I got it working. I need to improve my bench setup and clean the wiring up
Setup my bench to read a couple CCMs. but I keep getting the Bus is too Noisy.. I have not changed anything on my setup. Suggestions on what to check?
EDIT:
1990-1991 works but 1992-1993 keeps...
nevermind, I am looking a basic stuff and realized I can use the Max232 which will allow 5v on the ALDL side, Power but 3.3 volts and just work
Hello,
I am working on a project whee I am currently using an Arduino Mega to interface with the ALDL line and reading the data. However, I would like to use a Raspberry Pi Pico to do the same...
Sent and Email to ALDLDroid but I am having issues with my BUrn1 erasing PROMs. The burn1 and PROMs work fine on my PC. but just the erase seems to be an issue. Hopefully there is a n easy fix to get...
Oops sorry 30-60 seconds
I have a friends CCM, powers on them about 30-60 later shuts off. I know he cooked something but don't see any signs of a cooked part, anyone have schematics for these?
New screen in progress.. thinking of making an page for the ALDL full stream

Scott, going to look over your code again and make sure it will work for the 1990 and...
Thanks to all the efforts in this thread I have this:
made some display improvements today after finding that it was hard to see yesterday on my test drive

So I am not sure why, but i was doing something convoluted.. I used the above calculation now from spfautsch. Sometimes I just can't see the simple solution.
As for my comment of it not being...
I think I know where I might have gone wrong. I am going to look at my code tonight
I totally agree with you. It confused the hell out of me. I had it, I checked it 2 or 3 times. it should have worked that way for for some weird unknown reason it is not that way. Like I said I was...
I think this is still CCM related..
First, I was looking to do the Arduino Datalogger that spfautsch has, but I was going to tweak it for my car. Well that is still a plan, just not right now. I...
That is a good find!!
As for my project, it has been on hold due to weather and other things I needed to address on the car. I have a logger setup like spfautsch (hardware) but in the interim I...
Not on his website but is offered.. $100 I believe, email him and ask for it.
1991 CCM installed in my 1990 thanks to those in this thread.. https://youtu.be/AUCy_FxxNGg
Before anyone asks about the LCD, I have the interface board from BATEE, that allows the later LCD to be...
So it warmed up enough to get out in the garage to try some stuff. I was using NoMakeWAN's Arduino code to see how well I can just read the bus and grab the data.. that was not working too well. it...
NomakeWan,
that particular corvette is not named Christine or is red by chance is it? :laugh:
Good to know. I just brute force programmed a new value to it and called it good.. LOL
I also bought a set of resistors off eBay, all the correct VATS values.....
Would be more than willing to try out this when you get it further along. I am running out of driving time, weather getting crappy. I am also working on my Display and going to try an read messages...
yeah the C81 and C41 are CCM DTCs when the ECM/PCM is not present or not recognized.
As fit the code stuff. Yeah that always happens
Actually the error I would see for the 90-91 want C41. So it could be either, C81 was not on the 1990-91
Here is my better version of my bench. The green PCB is an old ECM setup made on Thirdgen...
Not sure Lingenfelter bought them all. Jerry's Gaskets has tons of parts. Only had to find parts, CCM, ECM and Ignition Module, but the IM is pretty stout.. As for Power, yeah I only have headers on...
