I would like to just say thanks to all the staff at Dobeck Performance for their help on the AFR+. The AFR+ is the easiest thing to tune and it allowed me to make peak horsepower on my vehicle. Thank you.....View More
SYSTEM INFO:
The AFR+ brings together two technologies within one system to make it the most powerful, user-friendly tuning device on the market. AFR+ combines an EFI controller with a wideband O2 sensor and AFR gauge to provide a user instant fuel trimming ability and feedback about their vehicle's state of tune.....Learn More about the AFR+
This system DOES NOT require the welding in of an O2 bung. The Bosch wideband O2 sensor will install through a supplied O2 Bung adapter into the factory narrowband O2 location. This AFR+ system uses the factory narrowband O2 system to trim to desired AFR values. The factory O2 sensor connection is plugged into the DP wideband controller. The factory narrowband sensor will be removed from the vehicle.
NOTE: Torque specification on 12mm to 18mm O2 Bung Adapter is 180 in-lbs. DO NOT OVERTIGHTEN!! Recommended to use anti-seize lube on adapter threads.
Recommended to reset GROM ECU after installing any after-market performance modification. Watch YouTube video below.
