phil_smeeth Posted January 26, 2011 Share Posted January 26, 2011 from the apexi website:The AFC-neo is a multifunctional sub-computer that allows the tuner to fine-tune air-fuel ratios, calculate MAF/MAP transfer functions, control VTEC or other solenoids, address stall issues associated with open-air blow off valves, and monitor key ECU data.Changes in air-fuel ratio are achieved by correcting the airflow sensor signal or pressure sensor signal at 16 different RPM points, and at high and low throttle positions, all of which can be moved according to the customers needs. By changing this input signal, the tuner can alter the injector pulse width as calculated by the ECU.The AFC NEO is unique in the sense that it has a built in MAF/MAP transfer function, which is necessary when the tuner swaps MAF/MAP sensors from one vehicle application to another. By setting the sensor IN and OUT to the appropriate sensor numbers, the AFC NEO can act as a translator/emulator unit, eliminating the need for costly sensor or ECU reprogramming.The unit also has a VTEC solenoid control function that allows the tuner to change the VTEC engagement/disengagement point on Honda VTEC systems (not compatible with iVTEC systems). The VTEC solenoid control and also be used to control other types of solenoids as used in nitrous-oxide and water/methanol injection systems.On MAF applications with open-air blowoff valves, there is a deceleration air correction feature that allows the tuner to compensate for the over-rich condition that occurs at throttle-off. By adjusting the MAF signal at throttle-off condition, the tuner can reduce the amount of fuel injected and prevent stalling.In monitor mode, the driver can monitor digital engine RPM, throttle position, battery voltage, airflow sensor capacity usage, pressure sensor data, Karman frequency, MAF/MAP/Karman correction factor, and solenoid on/off status.The AFC NEO is a universal unit that can be used on a wide range of cars and trucks that have an air metering system that uses a VAF, MAF or MAP sensors operating within the 0-5 volt range, as well as applications using Karman sensors. There are some unique applications that do not allow for the proper functioning of the AFC NEO. If you are not sure, please contact Apex for assistance.

knight Posted January 26, 2011 Share Posted January 26, 2011 Does the Nero fiddle with IAB mate?this only lets you move/change the 4300-4500 rpm vtec point not the 5800pm one! Link to comment Share on other sites More sharing options...
knight Posted January 26, 2011 Share Posted January 26, 2011 wtf is that? where does it plug in? how does changing when the vtec kicks in affect performance?The AFC Neo plugs into the ECU mate! Link to comment Share on other sites More sharing options...
mackinfella Posted January 26, 2011 Author Share Posted January 26, 2011 There's no way to 'tune' the IAB mate.You can turn it off though There is a vacuum hose going to the disk looking thing at the passenger side of the inlet manifold.Without the vacuum hose connected the IAB's remain open all the time. You can't disconnect the hose or you will get a fault code flashing on the dash, but if you use a tie wrap, make a loop in the vac hose and block it off (a bit like getting a kink in a hose pipe!) that will majorly reduce the vacuum pressure and leave the IAB's 90% open.Don't think it will give you much of a performance increase unless use raise the VTEC engagement point though.I'd recommend raising the VTEC engagement if you are disabling the IABs..... fantastic... thanks alot for explaining that...im very tempted to do this.. raise the vtec point maybe also.. its purely for the sound tho ha i have a few mates that are vtec mad and they said be carefull as that engagement can be very adictive lol i know what they mean now Link to comment Share on other sites More sharing options...

johngreen537 Posted January 26, 2011 Share Posted January 26, 2011 lol, the B16 engines are a lot more difinate when you hit vtec mate.The Apexi Nero is an expesive toy though, £300 ish, but you can buy buddy club VTEC controller's for £50-£70 on ebay Not as flashy, not as cool, but will change the VTEC point for you Link to comment Share on other sites More sharing options...

johngreen537 Posted January 26, 2011 Share Posted January 26, 2011 Certainly are cool mate. You do get what you pay for too The Buddy club just hacks into vtec without the flashly lightyness of the Apexi.I know which one will be in my car 1st chance I get though Link to comment Share on other sites More sharing options...
