APEXi V-AFC (Vtec controller)

anyone know if this is going to come out for the tsx? or if the current one is compatible with it?

edit: because i hear people saying how the tsx hits v-tec with only about 1k rpm left and its not enough



DIGITAL VTEC AFC


Piggyback Fuel Computer with Integrated VTEC Controller


Modifies manifold pressure signal and alters VTEC engagement point on Honda VTEC engines; Vacuum Fluorescent Display (VFD).


A'PEX introduces the first digital fuel computer that combines fuel computer functions with a VTEC engagement controller. The V-AFC features a user-definable, eight-point, adjustable fuel curve that can be set in 500 RPM increments. The range of fuel adjustment is +/- 50% at each of the user-defined setting points. The Fuel Adjustment function considers wide/narrow throttle and low/high camshaft settings, from which four different fuel maps are created (wide-low, wide-high, narrow-low, narrow-high). The integrated VTEC Controller adjusts the point at which the engine switches from the Lo to Hi cam during acceleration, as well as when the engine switches from the Hi to Lo cam during deceleration.


and also what u guys think about:

REV/SPEED METER w/ G sensor



REV/SPEED METER


Multifunction monitoring and timing device


Variety of functions such as tach, speed, 0-400m time, etc… in one unit.


Like the original, the new Rev/Speed Meter GP is a complete multi function measuring device designed to measure and monitor data such as vehicle speed, engine RPM, and elapsed times. However, the strength of the new unit lies in its differences. Probably the most obvious being its completely redesigned look. This new aesthetically pleasing model was crafted to match the likes of other highly popular A'PEX electronics such as the VAFC (VTEC Controller) and the AVCR (Boost Controller). The new screen utilizes the easy to read VFD (Vacuum Fluorescent Display) with built in light sensor used in many of A'PEX's line up. The new unit also delivers a host of new functions. Standard features include: Engine RPM, Vehicle Speed, Travel Distance, and Battery Voltage (All which can be displayed in real time graph mode, numerical mode, or analogue mode; 1-4 channels at a time.), Peak Hold, Replay (With 60 second playback.), Speed Limiter Cut, 0-100m/200m/400m times with trap speed, 0-100km/h/200km/h/300km/h times, Mid Range Acceleration (The user can preset any range of speed to measure.), Stop Watch functions, Best Time Memory, RPM Warning, Speed Warning, RPM and Speed Outputs (For external devices requiring an RPM or speed signal.), Tire Size Correction (For acceleration and timing accuracy.), and Vehicle weight input. One of the most exiting of the new features is the option to utilize the revolutionary A'PEX G-Sensor (Sold separately.). The G Sensor allows the unit to measure G forces in 4-way front/rear/left/right directions. This data can be plotted in a graph display to map acceleration characteristics and lateral G's on the race track, or used in an array of new features including: Highly accurate 100m/200m/400m times with trap speed and wheel-spin correction, Horse Power Calculation, and Loss Power Calculation. By taking advantage of the optional G Sensor, the user can produce extremely accurate power measurements. Usually, when measuring 0-400m times through the speed sensor signal alone, the meter will end measurement too early (shorter distance) due to wheel-spin. Using the G Sensor modifies the speed sensor signal, compensating for wheel-spin and producing impeccably accurate acceleration times.

Hits vtec with only 1k rpm left??? The engine has 3 lobes on a cam. First lobe is from 1k to roughly 4.5k. Second lobe is from around 4.5k to 6k and the last lobe is from 6k to 7k. Not certain what you meant, but the car is far more dynamic than previous vtec motors.

And, depending on the type of day/driving, you can feel the kick overs.

Is it bad that I like screaming the engine?

k20s in the rsx don't work well with a v-afc..i'm assuming the tsx won't as well. There is some logic with lowering the final lobe vtec engagement down a few hundred rpm. It would probably get ride of that nasty vtec dip.

I'd imagine the usefulness of such a divised would be hampering to the K24 since that device is not an iVTEC controller. Remember the k's use "intellegent VTEC" now. Gotta play with the switch over and ignition timing retard. Plus the cam now can change degree some what I believe.

I'd say its not worth it, even if it gets released for our cars. What we need is Kpro and 45-50 degree vtec cam gear, not our standered 20 degree.

Our K24a2 is a monster motor, but just not in our cars.

But if we get Kpro . Things will change fast.

edit: WOW just notice this threads from 03. LOL

It's true, I'm always happy to see an old thread bumped because it meant whoever did it was searching rather than being lazy.

not correct. the tsx does not have a 3stage vtec, it has a fixed vtec-xover point at around 6000rpm. but it is altering I think cam angle and timing all the way through the rpm range.

the engines that run on 3stage are the economy vtec engines found in the "lesser" cars. like the base rsx. there you have a engine that uses only 12valves under 2200rpm if I remember correctly, then opens the before 4 closed valves just barely, and then after x-rpm it opens up all 16valves to the max. also opens all 16 from a start if you mash the throttle. it does this for lean running and maximum economy.
