APEXI AVCR PDF

The next step is to program the AVC-R. There are some ground rules that apply here: When making boost adjustments, always get a friend to drive. This frees you to make the computer adjustments. You are heading for a crash if you are trying to drive under extreme boost conditions and fiddling with the little buttons at the same time. Trust me on this. Always make sure the pedal is fully to the floor when reading the boost.

Details The Apexi AVC-R Boost Controller allows flexible control over virtually every aspect of boost control, such as injector pulse monitoring and gear specific boost control. The Apexi AVC-R is a digital boost controller that allows the user to modify the boost pressure level on turbocharged vehicles. While there are many boost controllers on the market, none includes as many features as the AVC-R, period. Despite all of the complex features included in the unit, the AVC-R is flexible enough to be used by beginners.

Peak hold function embedded for data playback at anytime. Superior starting up and stability on the high RPM range. Possible to control boost at any engine RPM. Scramble boost function embedded. It is a function that boost can be up and down within a certain time at initial starting to meet the driving purpose. Embedded with intake pressure, engine RPM, vehicle speed, throttle opening, solenoid valve duty, injector valve opening rate and 2D trace mode with engine RPM in Y axis.

Various vehicle information can be displayed in digital, graphical and analogue forms. Data is backed up even when the battery is disconnected. Installing bracket is included. Analogue meter can display maximum 2 pieces of information. Digital data can display maximum 4 pieces of information, when peak hold is on, it is possible to terminate the real time display.

In setting mode, engine RPM is displayed in bar graph for easy selection, it can be checked on the display before setting. Gear position setting is to minimise the hunting and dropping from high RPM during boost control. Even at overshooting, gear control can still be performed freely.

Unit size: mm x 50mm x 23mm. This includes everything needed to change the boost pressure along with wiring diagram in english.

How to Install and Tune an AVC-R Boost Controller

Once we have the NE points set we need to take the car out and do a boost level check. Now we can go along the graph using the arrow buttons and raise or lower the boost at any points that had troubles. In most cases turbos that run internal wastegates the boost tends to taper off slightly at the higher end of the RPM scale. Go and check your boost level again, and this time monitor when the AVCR comes onto full boost most cars with smaller turbos should acheive this around rpm basicaly when we have learnt where full boost occurs on the RPM scale, simply take rpm off this number and we get an RPM number that i like to call a SAFE rpm zone. SHould look like the graph below; graph is only an example, different engines will vary. Now when we check the boost level it should be very stable if not perfect accross the entire RPM range. Only trouble is, this is all good but it is only for 4th gear.
