Okay so i have a 93 s10 blazer (tbi) with the 8625 ecm and im using tuner pro. I have the right com port selected right mask. I also tried win aldl with no success (8625 is not listed as one of the supported ecus). And i had my computer engineer brother build me this cable.

if that pic didnt show up here is the link (2nd one)

And here is my aldl plug. i plugged my data into the one with the orange wire going into it and my ground i plugged into the black with a white stripe and didnt use a resistor that comes off of the data.

Finally here is my problem... Im not getting data and the computer doesnt even recognize the cable ( tried it on 2 different laptops) i need help.

 

16168625 is a later P4 series PCM used in TBI trucks. P4 PCM is an advanced version TBI/CFI powertrain control module before GM transitioned to OBD-II in '96. Early C3 ECM interface will not work with PCM. PCM I/O operates at higher speed - 8192 baud vs 160 used in C3. Check Moates website for more information, but IRC 8625 PCM used $E6 mask. Use TunerPro-RT for data stream capture.

Pin M is 8192 is data.

Ok thanks for the help... I guess i bought the wrong chip adapter too i have the G2 but it has the blue memcal inside... So i guess that means i need the g4 right?

 

actually I believe you need the G1 adaptor, not the G4. To be sure, ask Craig at moates, he is a lot of help. I have an 8625 out of a 93 S10 PU that I am putting into my 87 TBI 4x4 PU, so I have looked at all the things I will be needing. RFMaster is correct, that circuit will not work for your application. If your brother is really handy with building interfaces, there are several available that will work with the 8k baud computers, go look at the "aldl and usb Q's under diy prom forum. there are also designs based on the MAXI232 chipset

 

Ok i will ask him. My brother is off at college so i guess im on my own building a cable. Or can i just use a cable1 from moates?

 

I would probably buy the cable from moates, it just works no hassle
