As described and worked right out of the box. No additional power supply needed, wired correctly and in new condition. Recommend for Ls bench tuning with Hptuners.

I was a bit hesitant after reading a few negative reviews, but the unit I received works perfectly. I checked for the issues others mentioned—Pines in wrong order, and bare connections—and mine had none of those problems. Build quality seems solid, and it's doing exactly what it’s supposed to. Glad I took the chance on this one.

Had to completely re-wire. Came with power supply positive and ground reversed as well as ground pin in incorrect location. Very poor quality product.

5 stars because it does what it's intended. However, check the wiring before using. Mine was wired in reverse polarity, therefore, would not work. Furthermore, the ground pin was in the wrong spot and needed to be moved to pin one. I referred to the sloppy mechanics wiki to get the proper pin connections. Additionally, the connector to the PCM is pretty cheap and doesn't fit great. Lastly, this works just fine and does exactly what you expect it to do. I was able to read and write without upgrading the power supply though I was fully prepared and okay with doing so. UPDATE 4-16-2024, I ended up upgrading to a larger power supply as the one supplied would not work on the P59 pcm. If your on a 512 P01 pcm it should work but be ready to upgrade the power supply potentially.
