What BOV are you using, and can you adjust the spring pressure? I use a Tial, which is fast enough to minimize this problem with the stock MAF in blow thru. I have to switched to the newer slot style maf (im using mustang HpX from vpn tuning) as these are not bidirectional mafs. They are much less s...

Street Tuning my Z31 using Nistune and the stock sensors wasnt providing the capability I wanted. I did some research online, and here is what I found. Much of this is already covered through various resources, but here it is all in one place. DLP Designs A/D Converter $30 http://www.dlpdesign.com/u...

Screw was in PO position. Which is same as P1 in terms of voltage output. Update: Tested AFR output using a Fluke 87 V meter, and a lab grade power supply to power the guage. Before I had been using a craftsmen non-auto ranging digital meter, and power through the car battery. The fluke meter shows ...

Matt, That is the method I have read about, and I will be trying that method next. IF the blue wire outputs incorrect data also (and I refrain my self from punting the AEM UEGO across the street) then I am going to make my own calibration curve: 1.) Record voltage with sensor unplugged (14.7 AFR) 2....

Further testing today. I grabbed an extra automotive battery. I connected it to the AEM UEGO as its power source. I then unplugged the wideband o2 sensor, this defaults the gauge to 14.7 AFR, which should be around 2.3 volts (IIRC). Using a Digital Multi-meter, voltage between the ground of the batt...

Just an update gentleman, The W/B reading's on Nistune were not matching my UEGO gauge read-out. They appeared to be off by 1-2 AFR's. To investigate, I monitored voltage output (white wire) of the AEM UEGO and compared it to the UEGO gauge read-out. Using a digital multimeter, I connected the white...

Okay. I have solved my own problem, it was a driver problem. This may already be stated somewhere, but I didnt see it. Here is how I installed: 1) Attach up to 8 0-5v input signals to the DLP board, Attach the ground to the vehicle chassis, and ensure each of the sensors your logging is also properl...
