Ok, first-2 questions, when I hook up the connections, the engine fan comes on-is that supposed to? next the SES light come on and flashes-like I've thrown a code-is that supposed to, when I disconnect, it goes away. And lastly-but puzzleing, is my computer says "Not Connecting OFF line Mode, check default settings-any ideas?

 

Rick,
First:
This depends on what you're using to connect. I thought you'd bought the ALDU1 from Craig Moates. If that's the case, there should be a three position switch on the little box. Up is for 10K Mode. This is the same as putting a 10K Ohm resistor between A and B of your ALDL. It advances timing and fixes idle at 1K rpms. The middle position is open. This is normal and you will only be able to receive 160 baud data from the ECM in this mode. Down is shorted. This is the same as putting the paperclip between A and B of the ALDL and will flash your SES light and energize most relays including the fan relay. If engine is off (ignition switch on) it flashes your codes, if engine is on, it flashes to indicate mixture. I suspect you are using to down position if you are using the ALDU1. You may also be limited to 160 baud data in this mode. I never use this mode for scanning.

Second:
This would depend on the software you are using. I thought I'd read you had downloaded ECM851. This Moates product, like ECM852 is a DOS based application. The ALDU1 is USB and it is unlikely you are using the ALDU1 in DOS as getting USB drivers to work for COM ports in DOS is not for the faint harted. I'm not sure if you are running windows and have a USB driver for the ALDU1 that emulates a COM port, that it would work with the ECM851/2. Maybe others have made this work, but I haven't bothered. Try TunerPro by Mark Mansur.

That's all I have until you come back with more info. I've made way too many assumptions to be of any real help.

 

Thanks Ray, yes, I did buy the ALDU1 from Craig,and it's as you described-if I read correct then it should be in the middle, not up or down, sound correct? I am running windows and have plugged into the
USB port-however, I'm really computer illiterate as far as "DOS'" or "baud rate", the Craig Moates is on a floppy-I do know that much.
And I may have to use the Mark Mansur program, but I thought Morley
was running the Craig Moates program without any problem-but, I do not know if he's using the ALDU1, I kinda think not. I have to go to work from 3-6, my daughter (computer wiz kid) will be over by the time I get home and can explain some of this-to an old guy.Hope I've made sense.

 

Oh, you've made perfect sense. I think Morley uses a serial to ALDL cable. This type of cable plugs into a 9 or 25 pin serial port on the PC and then into the ALDL. Serial COM ports seem to be the most reliable for connecting to the ECM. When your laptop only has USB, things get a bit more complicated. Morley is probably better suited to explain all this, but for the ALDU1, you'll need a windows USB driver (available on the Moates site (Moates USB Driver). Next you'll need software that is compatible with the USB interface you now have to your ECM. I dont believe ECM851/2 will work. You'll need TunerProRT or WINALDL (free). There are others like Datamaster that should work with the ALDU1 as well. You may want to start with WINALDL as its free just as proof of concept. Then buy something if you think it will be of any value. WINALDL is 160 baud only. These baud rates I mentioned have to do with the data rates the ECM will output. Our 165 ECMs are always outputting data at 160 baud, but can be commanded to 8192 baud. This data rate contains much more data and is updated more frequently than the 160 baud. In order to connect in 8192, the ALDU1 must have the switch in the up or 10KOhm position. The middle (open) position should be fine for 160 baud. I hope this helps some. I know it is a great deal to get your head around when it's new to you.

Best of luck.

 

Thanks again Ray, won't be home til 6PM, then my daughter will be there. However, I'm kinda wondering about the ALDU1, I'm not sure I need to have that in the equation-because I do believe I have a serial port.Thanks for all the help-be sure ,I'll be back.

 

Yes, somewhere on Craig's site it should say that the ALDLU cable won't work with his ECM program.

 

Hi Morley, did you mean the ALDU1 ? for some reason, having spoken with Craig, I thought it would work. Incidently-now I'm wondering if his ALDL cable with the autoxray connection that plugs into the ALDL would work without the little converter or rather the ALDU1 in between?

Thanks guys.

 

The AutoXray cable that came with the ALDU1 will only work with the ALDU1/APU1 or the AutoXray. One end is ALDL, the other is RJ something, not RJ45 though, I think. At any rate, the cable you have (CABL1) is used to connect to the ALDU1/APU1, let's forget about AutoXray for now, that's just where Craig gets his cable from. The ALDU1/APU1 are USB devices. They connect to a PC's USB ports. A windows driver is then loaded that makes the USB port emulate a standard RS232 serial com port. The software will then communicate through this virtual com port, through the ALDU1/APU1 and on to the ECM. If your PC does in fact also have a DB9M serial port and you had bought an RS232 cable like the type from AKM, this would connect from the PC to the ALDL without the ALDU1/APU1 in between. The standard serial ports will work in DOS and you could then use the ECM851/2 software. You could probably even use this setup in Windows95/98/ME.

 

And this is why the cables won't work with his ECM software, it runs in DOS and the cable drivers are windows.

 

You know-sometimes I just need to slow down and digest. I in fact did
pose a couple questions to Craig about his cable and converter-if you will. My fault, his site does say it won't work with ECM 852, when I questioned wether it would work with ECM851 he reponded very quickly and honestly. In fact he stated not once but twice-that I should use the TunerPro RT software.Thanks for sticking with me on this guys Now, when the kid comes over today I'll have her download it for me. BTW, she was over last night-I do have the USB port, like I said, but no serial port. Sometimes I get just like a kid-to excited to think straight, at 62-maybe I'm going through that second childhood.Thanks again guys-will let you know.

 

You'll get there Rick. Next you'll be asking about .ads files!

 

ad files I don't know why I do these things to myself

Right now I'm taking a break from putting together one of those 10x10
yard sheds-geeeeeeesh, will I ever learn? You know-requirers assembly.
I'd been better off building one from scratch!

 

Well, my daughter came over, I had her delete the Moates program-well, I do still have it on a floppy. Nevertheless, I had her download the TunerPro RT, which Craig Moates suggested by the way. Haven't tried it yet-but, his paypal button isn't-or doesn't seem to be working-I'll send him an email Monday.
