no. as stated quite a few times in the auction page, it is meant for OBD1 vehicles with an OBD2 connector. this only happened with certain 94-95 models.
Ok guys. Finally got a chance to play with the ft232 adapter. Test for valid interface=cable found and working. click on connect says connecting then a second or two later changes to no connected. Never says connected also shows no data (i know the two go hand in hand) ;) working on a '7747 ecm using driver version 2.08.28 any ideas? Thank you in advance.
i'm not a definitive source on anything 160 baud related... but you have a correct, known to work ADX selected?
also, if you have it accessible, is the Rx LED lighting up as if the ECM is sending data?
Using adx v5.2 one of Marks. No, when i plug the cable into the usb port on my laptop all lights go off, otherwise with adapter hooked to aldl pins E and A both red & green lights flicker with the key on run. Odd thing in TP is when chcking interface i found that even with the cable unplugged it show cable found and functioning. Now that is on comm 4 if i switch to comm 5 or 6 it doesnt detect hardware. Something is t right here.
if the cable is detected even when unplugged from the computer, the wrong port is being used. my laptop does that with COM3, it is essentially a ghost port.
Also, I am using the osepp ft232 adapter and have the tx and rx pins soldered together if that makes a difference.
Ok so i gotta find out which comm my adapter is using then? Win xp yeah
i don't remember exact steps on XP anymore, but you'll need to get into the device manager and look in the ports section. when you plug the cable in, a new serial/COM port should show up, that would be the cable.
i want to say, open start menu, right-click on "my computer", properties, then one tab shows the option to get into it.
Got it workin! After changing from "use plug in" to autoprom and back to use plugin, switch to comm5 and im logging data. Bout time lol. Thanks Robert for your input. Have a great day. Now i can start tuning this thing.
strange..... i've never seen that process be required before. i'm not complaining, if it works.
