APEXI AVCR PDF

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.

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.

AVC-R Installation

For my 93 MR2 Turbo, I extended this section about 10 feet, then used a braided sleeving over the bundle. The first challenge was routing the wires. Since this was part of a larger project, I had quite a few wires to handle. I had already decided to mount the control module in the ashtray well, so I had a minor modification to make to that. After removing the ashtray, I cut a notch in the right wall of the inner housing to provide a spot to run the control module cable: Although the ashtray lamp housing is still attached in this photo, I later removed it, as it was totally unnecessary.

How to Install and Tune an AVC-R Boost Controller

Read directions to check, but these should be very close for all FDs. Grph Scale: These are units for the graphing view modes only. It works The basic idea is, if boost consistently overshoots, increase number; if boost oscillates, decrease number. However, I found no perceptible difference in boost pattern, no matter what I set this value to. With this turned on, I found that the unit kept dialing my transition spike back IN eliminating spike is later. But learn mode may work better in your car
