For instance, I had a narrowband audi TT MAF in my car, thinking it was a wideband TT MAF. These MAFs differ ever so slightly, the stock calibrations are pretty close. I tuned for the wideband MAF, and while fueling was "close", it hunted like yours. Once I figured out that I had a different MAF and updated my MAF scaling to match, it was dead nuts. |
