I downloaded it to check it out. It looks a little intimidating beings it doesn't have any appealing graphs and such. The newest version I could find was from 2007. I don't have a lot of money to spend right now because I'm upgrading different areas of my car, but I got all winter to play around with this stuff and set tps, blm's, iac, etc. I've put bigger injectors in also so I'm not to worried about duty cycle and stuff like that. I just want to get my current setup tuned in until I get money for some real equipment. I just need it for getting a baseline. Is there any how to write-ups to understand it better or is it easy to get the hang of? Are there any programs out there for the bastard 93 t/a? BTW I am using this on my 87 buick we4. Unfortunately my midnight metallic blue 86 tpi z28 is no longer with me. 5 yrs of hard work, and I end up selling it to put furniture in my new home. My friend is obsessed with them still to this day so I'm sure I'll be wrenching on one very soon Thanks for savin from the crusher guys! I will be posting a nice autometer tach in the parts for sale section if anyone is interested.

One more question, has anyone figured out how to get data stream directly from the factory service port instead of the aldl port?

hectorsn

Yeah, the ecm board data retriever was figured out long ago for some of the much older ecm's like the low baud early 80's stuff and I thinnk the 7747 TBI ecm. Dont know if it applies to your ecm. The info was at GMECM archives and other pioneer ecm sites. I dont know if that stuff still exists though. Get ready for some searching. OOh, IIRC you can also use that connector to do on-the-fly PROM changes. Seems that's what the factory used to data collect and tune while R&D'ing.

The TB ecms are 160 baud. I'm not to concerned with the 93 t/a, that's gonna stay stock or stock appearing at best. It's the wifes so I'm not gonna throw a bunch of HP stuff on it. The buick on the other hand, that's hard not to mess with!

I don't know a whole lot from about this stuff, but isn't there plugs out there that can go right into the service port?? I thought I saw them on moates or something. But if they sell a plug, can it still be wired up to a serial connector and still be used with winaldl or tunerpro? I can't believe there aren't any threads on here about doing this. You guys seem to be a little bit more DIY than the TB guys.

If you have ANY info on tapping into this port and what connectors to buy, can you post them or PM them to me. Money is tight as it is, I can't afford to buy a pre-made interface for nearly 300 bucks!!!!!

Now you have me confused. Are you talking about the service port on the back of the ecm or the ALDL port uncerneath the dash? If you mean the service port at the ecm I was looking through some old posts in the DIY-PROM area and came across the name of that datalogger thats at the ecm port. Search for "lockers" either on this site or at DIY-ECM or GMECM or something like that. I havent done this for a while (like 5 years) so I cant remember exactly the where, what, how. Now to datalog at the ALDL I use the Moates ECM852 which is an old program he made way back when. Remember I did say that I havent done this for 5 years so all my equipment is old but it works just fine. The newer stuff is prettier and fancier and faster but it does the same thing in the end. Since I too am tight on money I wasnt going to step up to all the new stuff so I just went with what I had. I know he still sells all the basic stuff like the rs232 interface for the aldl to serial port and that is nowhere near $300 doing your own soldering. Back when I got all my prom burning stuff in 2004 I spent about $350 total for a prom programmer, aldl interface and tunercat with two ecm definition files. Adjusted for inflation and updated components today might be $500. Then again, tunerpro is N/C and is an excellent tool so that could replace TC and you can get back down to the $400 range. A laptop is necessary regardless and a good one off ebay is $120.

LOL ok I'll get things straightened out for ya. I know I got too many questions going on.

1st question, which was if anyone was still using winaldl and which was better-winaldl or tunerpro

2nd question-I would like to tap into the service port on ecm GM #1227148 86-87 vin7 for buick grand national. Is there a cable that can plug right into it and wire up to a serial cable or do you have to build an interface? Basically I just want to know where or how to build the cables and stuff to tap into this port. Could tunerpro or winaldl be used with this type of setup?

hectorsn

Sorry, I never used winaldl but moates ecm852 is also free. The service port question is "lockers". Thats the only thing I remember about that thing; almost certain it was a diy piece entirely as I dont think anyone sold anything for it. I am almost one thousand percent positive that the GN ECM is covered. It too was 160 baud. You're going to have to get your search on. DIY PROM might have something on it but GMECM definitely had what you are looking for.

This is a much better way to go about tuning (service port), why don't a lot of you guys use it? I thought I saw something on MOATES, but I really don't know what I need or what I'm looking at because I've never had my ecm apart. I don't wanna screw with it unless I get the interface parts lined up by somebody or get a spare ecm to rip into. The pics on the site are kind of small and can't tell which cables went to what If you have time can you help or at least find someone to help me with what to buy? I'm gonna search the web some more but I really don't know what I'm looking at that's why I brought this up. If I get any leads on my own I will post them. Should I start a new thread on tapping the service port?

Tapping into the service port is not nearly as easy as using the ALDL port. The original Lockers project grew into the Embedded Lockers (EBL) product. This is available for the C3 ECMs that are used in TBI systems. There is also a Port Mod available for use with MPFI vehicles while using those same TBI ECMs (batch fire).

Has high speed logging, auto VE Learn, a Windows interface, Flash memory on board for the calibration, along with a host of other features.

For the '89 TTA (aka, '86-'87 GN in a sleek body) there is the Power Logger. It is a more recent product that also taps into the service port. Although it is a data logging only system.

I am aware of the powerlogger setup. The problem is I don't have 269 to buy it so I'm trying to find out if I can find the adaptor to run off the service port elsewhere or find the plans to make it.

aldl updates 1.5 times per second at standard rate.

running off the service port updates at least 18 times per second. Big difference there!

I am aware of the update speed using the service port. It is only limited by the transfer rate of the communications link and the size of the hard drive.

hectorsn posted where you can find the plans for a service port logging setup. Note that I do not have any PCBs left from that project.

ok I will research it later and let you know what I find. I must have overlooked the how-to on making it when I was at the diyefi site. I'm surprised you guys haven't put up a sticky on how to do this. I think it would be a much better for tuning than using the aldl port.

I found this website http://www.diy-efi.org/gmecm/

I dunno, it looks like the info got wiped out at diy-efi. RBob do you still have the schematic for building this thing up? I remember when I first got into this thanks to good ole Grumpy and running across the board schematics and thinking how cool it was but since I was using the 730 ecm and it didnt support it and the ecm already had fast enough data transfer I never pursued it. Since I've been away for such a long time (5 years ago my life got turned upside down) and everything has changed to be more commercialized as opposed to DIY it would be nice to get back to some of the old feeling of learning more by putting things together yourself. Well maybe just for me anyhow since my learning got cut short. Dont get me wrong, I am in awe of your EBL and cant fathom the amount of time you have spent working on it and it is an invaluable resource for the number of people using it. I cant imagine a better ecm out there for anyone using a dizzy. Simple in design and inexpensive yet full of features. Its just that your original lockers was so cool and it helped so many people it seems wrong that such an awesome project from the beginnings of GM ECM hacking has all but been forgotten. Oh BTW, what data software was used with the original lockers? Or was it something all softwares could use?

i too would love to build the lockers for my 7148 turbo buick ecm. I am in work though, so i can't search to many sites right now for the specs, schematics.

Sweet you got a wagon! If I ever find a clean regal wagon around here I'm definitely gonna build it for a DD, even gonna drive it in winter. It might just end up being carb turbo to keep the costs low but I still wanna do suspension mods and all that. EMail me some pics of that wagon Are you on TB.com?

I have some pics on my cardomain site, I have the same username over at TB and maliburacing.
