Scanner just reads zeros.

[yellowfever]

Can someone check out my scan and scanner setup. The maf tables will only read zero and the wideband is reading rich. Why.

reads more than 0 for me.

really.Boy I'm confused. All I get is zeros in the maf tables. Except the wideband one.

so why does it read zeros in the maf histograms, except the wideband one. I have tried to use two different ways to set it up that I have seen on here. I'm not sure why its not working. Everything worked fine on my old laptop. When it crashed I downloaded hp tuners on this laptop, and I cant get it to read in the maf histograms.

Sound like your config file not set up correctly or you are missing the Histograms themselves.
Upload current config or find a good one to download.

If your referring to the fuel trims staying at 0 in the Maf histogram, that is because your in open loop. Look at your table display, your STFT & LTFT are 0. And you need to delete bank 2 fuel trims, O2 sensor and injector pulse from your table display. As your car doesn't have a bank 2 fuel control and also any bank 2 pids in the table display can cause histogram/chart display fuel trims and injector duty cycle values to be halved.

Thank you Russ. Yes that's what I was referring to. My fuel trims are staying at zero. Thank you, I will give that try.
