Fixed Frequency Mini AFC

EP-FFAFC-LSJ $129.99
Regular price $129.99

This product is intended for very high horsepower builds. It will lower your MAF frequency to 82% of the original value. This allows you to work around the 11,100hz limit in the ECU that creates tuning issues on cars making 350WHP or more.

This device lowers the MAF by 18% so you’ll need to multiply the PCM MAF table by 1.45. It is not adjustable.
