i have a stock r and someone got one for cheap, what exactly does it do?

 

Same thing that a regular (V)AFC does but slightly more options, and better looking display.

Crome/Hondata/etc.. Are usually a better option anyway.

basically what he said.. it's a smaller unit with a few more options. How cheap is cheap?

 

2 bills

"Same thing that a regular (V)AFC does but slightly more options, and better looking display" to quote but i don`t know about either.

what do they do and is it any benefit for a stock r?

 

You would spend your money better using Crome,uberdata,or hondata...as the other's said...The neo is the same thing as the other,just a couple more options and a color display

 

sorry man,i dont know what benefits these products do. the web site does not say what it does to the vehicle

Seems like you don't know the basics. the AFC is a piggy Back controller which allows stock ECUs to do things that they normally can't do, like run larger injectors or deal with boost. You can adjust the air/fuel ratios, VTEC crossover, timing and etc.. Why piggy back (VAFC, etc..) controllers suck: Remember that piggyback controllers work by altering sensor signals before they get to the ECU.

Most of the time, the primary signal being messed with is the Map Sensor. This is critically important in a Speed Density car. The Map Sensor is used by the ECU to guess how much air is going into the car, and therefore how much fuel to supply in order to match airflow. When you "lean" out a car with an AFC, you are simply decreasing the Map Sensor signal - the ECU responds to the decrease in manifold pressure by supplying less fuel. When you "richen" a car with an AFC, you are simply increasing the Map Sensor signal - the ECU responds to the increase in manifold pressure by supplying more fuel.

The change in fueling happens for a reason: if you look at a fuel table, Map Sensor values correspond with columns. When you increase or decrease the signal from the Map Sensor, you are simply making the ECU use a different column than it originally would have used. (see Understanding Maps if you need some help understanding reading Fuel and Ign tables)

But wait, isn't the Map Sensor used for determining ignition requirements too? When you "lean" out a car with a Piggy Back, you also in all likelyhood advanced timing. When you "richen" a car with a Piggy Back, you also in all likelyhood retarded timing. Look at trends horizontally (as MAP changes) in an ignition table, and you will see why this happens. This helps explain why so many boosted cars running on the "AFC hack" have issues due to excessive ignition advance.

The bottom line: Piggy Back Controllers suck because you cannot independently adjust fuel and ignition. Any changes to fueling will produce a change in ignition too, and often this is undesirable. Source taken from Phearable.

The products mentioned are engine management/tuning software. Which are used to adjust fuel, timming, vtec engagement, etc.

Neo_ just walked all over my response.

neo: did you write the book for Apex'i?

 

thanks neo, i understand now.cheers

 

 

It's a method of tuning the car...but not something you just want to hook up your self if you dont know anything about it...i've seen people put these in their car and just start pushing buttons... Maybe this will help a little...https://honda-tech.com/zerothread?id=1578524

-edit- Neo just typed all that while i just typed that...dam, he walked all over mine as well.... P.S. I'll stick with my chipped ECU

 

great WU Neo

Obviously, thats my ITR's tuner.

BTW, its from PGMFI. I never took credit for that.
