problem with RS232 to USB with tuner cats i am getting an error message with my tuner cats and one of the potential issues is the rs232 to usb interface. i installed the proper driver. any advice?
I have an issue that my driver keeps changing my USB comm port to port 10, instead of port 2 where I keep setting it. Any time it doesn't work, that's the first thing I check. I have the adapter that radio shack sells, the more expensive one of the 2 they sell. I know this isn't an uncommon issue with these adapters. I've seen this happen with other equipment, that required these units. I've had the best luck with the Beldin units, but I poofed mine and didn't get around to sending it back yet and Radio Shack was around the corner when I needed a new one
What error are you getting exactly? Is it just throwing a comm port error or something more specific?
I've used the Belkin serial adapter and haven't had any issues whatsoever, but every other adapter I used was plagued by connection problems.
Also I'm assuming this is for your Iroc? I would double check that your ECU file is correct because IIRC 1985 ECUs were different than all other years and require a different file to read them correctly.

not the IROC. for the formula. it is using the correct port and the message i am getting is an "unable to communicate with PCM"

i am sure i have power. i have checked the CIG/ACCY Fuse and plugged the code reader in and it worked fine. so i know i have power.
Does the USB-to-serial converter/cable have any leds in it? I don't use a Belkin, but mine works (for a different app) and it has leds for power, Rx and Tx. I can see the power led when it is connected to the pc, and the Rx and Tx leds blink while communicating with the PCM.

The first thing I would check is to look a the pins on your RS232 cable and PCM connectors to make sure they're clean and not bent. Going from OBDII to serial and then to USB is a lot of converting, one little spec of dust or a kink in the wrong place could throw it off.

I almost guarantee that it's an issue with the converter communicating with Windows or the cable itself. There's a lot of converstions going on that add to the conplexity and Vista just adds another level. Can you datalog with any other program?
