question for people who tune

[silverado13]

i know this is going to seem like a very amatuer question, but those people using efi live and other tuning programs, how are you connecting you computers to your obd2 ports? i saw on the internet that they have obd2 to USB cables, is that what people use?

Yep just a 16-pin OBD2 connector on one end, and a USB at the other end.

no, there is hardware that needs to go between the vehicle and computer its not just a OBDII conntecter to USB....at least for EFILive, you connect a OBDII connector to the vehicle which connects to the EFILive V2 module hardware, then a USB connector from the module to the computer. I'm pretty sure its similar for HPT and possibly Tunercats.

You're OBDII on a 97.

The cheap ALDL cables are pointless unless all you want to do is data log.

Each tuning software package has a cable that is proprietary to it.

EFILive has it's cable, tunercatII has it's own cable (it's what I use) and all the rest do as well.

Tunercat is about the most open one and the hardware can be sourced separately if you know what to look for. I can't say what due to licensing agreements. Even then, it requires a pretty secure password to activate the software. To add insult to injury, tunercatII is no longer available for sale as a stand alone purchase. It was sold to JET which mucked it all up.
