I like the AEM 30-0334 for CAN vehicles (typically 05+, or GEN 4+ GM stuff)

The idea behind this cable is to allow you to go from vehicle to vehicle quickly as a tuner. Or perhaps you want to use a wideband to tune your car but not to leave installed. This simplifies that situation.

I've used a version of this cable for quite a long time now in the shop.. To the point I was wearing them out. So I asked our wiring dept to make a big batch of them this time. We intend for our remote tuning shops to use them mainly.

Plug the cable in under the dash, with your HPTuners cable and go straight to the gauge.. The Gauge will be powered as long as you leave it plugged into the DLC. This is a handy feature cause otherwise it's hard to catch startup AFR because the wideband is warming up. This cable will leave the sensor warm.
