just got lt1 edit for 96 and when i try to download the tune it says trying to conn to the pcm... used edit on this pcm before but no worky now anyone had this before and know how to fix this...

 

check the cable connection, make sure the COM port settings are correct also.

 

na i ck them they where all good...

 

have you checked the com settings in OBD2Prog to make sure it's attempting to connect on the proper port?

Have you tried disabling your Antivirus software to see if it's conflicting?

Are you using a true hardware serial port or a USB adapter or something?

 

the or something i bought a 9 pin to 20 something pin printer port adapter no
other port... did this once before with tunner but he swaped laptops and it worked just trying to find a fix for this....

 

the computer is seeing the cable and the 1st light is on when it is pluged in...

 

To my knowledge the LT1 edit cable will not work on a printer (LPT) port. Are you talking about a 9-pin to 25-pin serial adapter? Some old serial ports were 25-pins. I have had problems getting the 9-pin to 25-pin adapters working in the past with some mice, so maybe that's the problem.

If you REALLY have it connected to a parallel port (printer port), then I'd bet that's the problem.

 

ya but edit is seeing the cable and the two are talkin but it wont get to the pcm if it will not work with this will it work with usb adapter...

 

some USB adapters work, some don't. It's hard to say.

My cable doesn't blink when just connected to the computer. But it will blink when connected to the car even if it's not connected to the computer.

 

thanx for your help just tryied to go cheep and it did not work but got it with usb adapter...
