The AEM EMS costs 1900 euro over here and the FIC only cost me 500 euro so there is a big price difference.
I have pasted the features below for the FIC:
Percise Fuel Delivery
The F/IC intercepts the signal to the stock injectors, allowing the user to modify pulse-width by +/-100%. The F/IC is the only piggy-back system that can decrease injector pulse-width, allowing the user to drive larger aftermarket injectors* while still maintaining proper air / fuel ratios. This powerful system can also tap into the factory injector signal and work independently to drive up to six (6) additional injectors
TIMING RETARD CONTROL
The F/IC has the ability to retard timing by intercepting and delaying the outputs from the cam and crank position sensors to the engine- with no adverse affect on applications equipped with variable cam timing. The F/IC can retard timing from the factory system based on engine RPM and load inputs.
SENSOR CALIBRATION & CONTROL
The F/IC can also be used to recalibrate / clamp the MAF sensor, eliminating common problems with non-boosted factory MAFs. The on-board MAP sensor allows for proper fueling in boosted applicatons.
I will have this installed on October 10th...
