Product Description
The AIC1-V6H/EV6 is a highly specialized version of the AIC1. It is specifically used to add six additional port injectors on in-line 6-cylinder, direct injected engines. As with the other versions of the AIC1, it is programmed with the R4 engine management software which is included. Connection to a laptop is made through a USB to serial adapter cable which is not included. The USB to serial cable we sell on this site is highly recommended.
Instead of an internal pressure sensor, the AIC1-V6H/EV6 has a voltage input with a 0-5 V range. The voltage input can come from a stock or external map sensor, or from an MAF sensor. This means the load can be based on either pressure or flow and is not limited to a fixed range.
The AIC1-V6H/EV6 requires a true-tach input signal which is a square wave signal that pulses for each ignition event. Many ECUs do not provide a true-tach signal because the tachometer is driven by a CAN bus signal. On applications without a true-tach, a tach adapter may be used. Fortunately, BMW does provide a true-tach signal on most vehicles which can generally be found on pin 9 of the diagnostic port. This unit is ideally suited for N54, N55, S55 and B58 BMW engines.
This unit comes with EV6 injector connectors. This unit does not come pre-programmed. It is essential that you load an appropriate map before running this unit on an engine.
Legal only for racing vehicles which may never be used upon a highway.
