The Nexiq USB Link 2 is much improved design

The Nexiq USB Link 2 is much improved design, and we are sure that it will sell very well for a long time given its history and distribution network. We are constantly lurking in message boards and forums, and there have been reports of it not working with various equipment, but these are usually unfounded. We have yet to run across an application that would NOT work with the NEXIQ-2 USB Link. If you do have one, please leave a comment below and let us know!

For all its popularity, the original Nexiq USB Link had some serious design issues. The main issue was with the USB connector at the bottom. The original design was very poor, and lets face it, these devices are being used by diesel and auto technicians. To say they are rough on tools would be an understatement. The main problem is that due to the bending of the USB cord and constant plugging/unplugging of it, the USB port would break off the motherboard inside the device.

When this happened, you would have to send it to Nexiq to be repaired. Although the cost wasn’t bad (Around $150), the downtime of 3-4 weeks is what made it difficult for people. Nexiq did go through a couple “fixes” for this, such as creating a USB Link 2 (shown below) and upgrading the USB port to the heavy duty “orange” style. By using both of these options, it did tend to help the issue. I only bring this up, because the new USB Link 2 appears to have solved that issue. The design they’ve come up with made it so that the USB cable really can’t be pushed around, and it gets “socketed” into the adapter.

MY Tech2 scan tool has reported this issue for a while. My car has been throwing a mass airflow deviation code sporadically while driving. I reset my ecu, drive around for a while but the code will pop up again. When it throws the code the ecu also limits torque (the 04’s way of limp home mode).

I have gone through all of the vacuum lines and was not able to find a single leak anywhere. I think the MAF sensor is bad but I just wanted to get an opinion before I buy a new one.

Here are two pictures showing what the GM Tech II is reading, one is the fuel adaption and trim which should be close to 0% I believe and the car is doing this because of the air deviation. The other is the actual air deviation test; normal fuel correction should be closer to zero, I think it says normal range is between +/- 5% and same goes for the air deviation at idle.
