Sorry for replying on this old thread. I am in the process of making an interface for my 1990 chevy van to show this data. I was wondering if you made more patches of your gauges software. A nice addition would be calculating the gas mileage, but there are a few variables you will need to have extra such as airflow.
If you have newer versions made, could you post it here?

My chevy is at the garage for repairs, and I will need to buy an aldl cable.
I have downloaded your source files.
If you think it is OK to use your sources. I am going to have a go at parsing the ds files posted here, it would be really useful so your solution isn't only for the regal you owned. There is a big change some of he fellow vanners here in the Netherlands will be interested too.
Probably most code will be refactored. Adding the options to view the meters you want etc. Is there anyone interested in new versions of this software on mp3car? (if I can get it to work off course  )

I am going to add a parser to understand multiple datastreams based on the following ds files:
http://www.mp3car.com/vbulletin/engi...ml#post1080254
would there be more people on mp3car interested? If I get it working I will post it here, if I gt it working and someone will is interested. Some Dutch vanners are already showing some interest for this software.

Sign me up. I own a 1993 Chevy G20 and plan on doing something similar. However, I'm not sure if I will use the ALDL port or if I'll just custom wire all the gauge sending units to a Fusion Brain.
The turn signals will require a Fusion Brain anyway.

i am in the proccess of trying to get data from my ecm. it is a 1227730, and that runs at 8192 baud. so far it seems the only thing that is going to work for logging with this ecm is the APU1 from moates with either Tunerpro RT or i believe tunercat. but i am also trying to tune it to get the new engine/ecm combo to work together. its the 3500 from an 06 malibu with a obd1 ecm.
ok, i think im done bragging. but i am definantly going to keep up with this.

I have an 87 camaro with a '165 ECU, and wrote my own interface. If anyone is interested in some of my c++ code, I wrote it using a cross-platform library called Qt, so you wouldn't be able to compile it without that, but the concepts in it are useful for the communication. protocol.
I warn you, the UI is ugly and the code is very dirty as it is still in development, but maybe it would be of some use to someone. Once I get my carputer into the camaro I'm going to be running this software full time.
the MPG display doesn't work right, I'm still working on the function to calculate it, so don't get your hopes up on that one :P

is that ecm 160 baud or 8192? im guessing 8192 unless a conversion of some sort was done. i am waiting for my max232 chip to come in from mouser to finish up my 8192 baud aldl cable.

Mine is one of the "hybrid" ecu's. It does both, but I run it at 8192. usually. The 160 baud shows less than half the information that the 8192 does on mine.

im still learning about all these late 80s gm ecm's, never knew there was a hybrid. but from what i have been told, 8192 baud ecm is much better because it samples data and outputs it quicker than the 160 baud ecm. i dont remember how many times a second each samples. i just know from experience and what people have said after the conversion done on their fiero that it idles better, runs better, transfers power better, has better throttle response, and no rev at startup. along with other things that arent coming to me at the moment.

The hybrid thing I think was purely the '165 ecm. I get around 10hz sampling from mine in 8192 baud mode. I actually just upgraded the code in my chip to the 88' code, THAT runs much better than the '87 code, and the ALDL doesn't stop responding like my 87 code used to.
The APU1 is pretty good from what I hear. I have the Ostrich 2.0 + ALDL cable combonation, but the APU1 allows you to read your stock chip, and burn new chips too (which is awesome) I should've gotten that
Interfacing with the APU1 via ALDL should not be difficult at all, but TunerProRT is a good program to use, it's what I use to compare against my program and make sure I'm doing things right
I'd like to finish my touchscreen compatible data logger, Tuner-Pro is very untouchscreen friendly.

I just got my new engine back from the machine shop, I'm hoping to have it in by the end of Jan. so I can start working on ALDL stuff again. Been working on OBD2 stuff in the meantime
