Greetings.
Bought and installed an AEM 30-0300 wideband. Running HPT version 4.4.4.
No matter what I do or set it to, be it AFR or Lambda, HPT is not reading the output correctly...
AFR= Constant 19.18, even though the gauge shows actual AFR
Lambda= Constant 1.32, even though the gauge shows actual Lambda
Im so fricken mad. Im going to contact AEM tomorrow and see if they can help.
Can ANYONE help me with this?
Thanks in advance!
Not reading the output... which output would that be? Serial via USB or analog? If analog what's it connected to? MPVI2 pro or an unused ECM sensor input?
If its the analog output, the problem usually is the Analog- wire not being grounded to the scanner.
To double check things, a single fresh AA battery usually has a voltage of about 1.6v. Connecting it between the analog input and ground ( with the gauge DISCONNECTED ) should cause the scanner to show about 11.0AFR or 0.75 Lambda.
Analog. And it's been connected to the prolink via the red and blue wire. Forgot to mention I'm using an MPVI2. I was so upset last night that I failed to mention that...Quote:

Yeah... I have a MPVI2. Pro Set and Prolink. Ive scanned a 30-4110 and a Innovate MTX-L with no issues. Im wondering if the WB is defective. I have tried all combinations of input and offset with no success. The output NEVER changes. CONSTANT 19.18 shown in the scanner while the gauge shows true. ARRRRGGGHHHH! LOL!Quote:

Not yet. I was in a situation where one wasnt available. I will check it at lunch, if I can find a DVOM here at work.Quote:

Gotcha. I was going to try that anyway. I will see if I can find a meter. Thanks!Quote:
