Can I run a 2.0 L gas MAF on a diesel TDI with a chip?
Yes, but your car may produce excess smoke under all rpm conditions. It may also exhibit a hesitation when coming off steady part throttle conditions. I recommend adding a trim pot or fixed resistor to the maf signal to reduce it to match the requested signal. Check with Fred’s TDIclub site for details. If and when the maf modification is dialed in correctly, you can log a vagcom run and watch the actual values closely follow the requested up to 850 mg/R. The 2.0 L with out the resistors will read upwards of 1275 mg/R and may throw maf code.
