APEXi POWER FC & FC COMMANDER

This is a full-replacement computer, which can be just swapped with genuine computer and makes it possible to control high performance engine. Genuine computer doesn't have to be traded in when purchasing this POWER FC, so you can keep your original computer with you for the case of emergency.

The ROM in the POWER FC has specially programmed data, which offers maximum performance to each engine model. This sporty engine management system programmed by APEXi is not only reprogramming the ROM but also it uses controlling system which is much superior to genuine ECU.

Also POWER FC can be set to your own desired setting by just connecting the hand-held controller called FC COMMANDER. By reprogramming the each control MAP and data, POWER FC will evolve into the special computer that is programmed by you. Of course it's also easy to get back to original factory setting when needed.

FC COMMANDER will show you three functions in the menu after powered on . Then you select one of the three functions, which is "monitor mode" for multi-function monitor, "setting mode" for programming original MAP and "others" for setting of each devices on the car.

In the monitor mode, you can see ten kinds of reading such as engine rpm, speed, injector opening percentage, ignition timing, air flow voltage (or pressure voltage), boost, and so on. These data will be shown by the numerical value and also can be shown by graphical picture. For the other function, if you select MAP trace mode, you can trace the MAP of fuel injection and ignition timing. Each function is just controlled by pushing button on FC COMMANDER.

In the setting mode, you can reprogram any setting for the engine, which are the change of ignition timing MAP, the change of fuel MAP, the correction of air volume signal of air flow metre, the correction of fuel injection interval, boost setting, the correction of the extra fuel volume for acceleration, the correction of fuel and ignition timing, the change of the fuel injection volume at cranking, the correction of coolant temperature, and the tacho setting. These factors can be changed or corrected very easily. Just select the point which you want to change from the MAP or graph and change it in the setting mode.

And also you can control the boost with optional POWER FC BOOST CONTROL KIT.

Brand APEXi

Category Electronics

Concept:

The Power FC proudly stands as A'PEX's answer to the constraints and limitations associated with most piggy-back style fuel controllers. The Power FC is a complete, stand alone, total engine management system capable of handling virtually anything thrown in its path. From multiple point fuel and ignition control to VTEC engagement (Honda applications) and boost settings, the Power FC is capable of accommodating even the most demanding performance enthusiasts.

Characteristics:

Currently available only through Power Excel Shops, the Power FC replaces the factory ECU and controls all engine parameters.(Off road use only, no OBD-II) Installation is as easy as replacing the factory ECU. (Some minor rewiring is required on select vehicles.) The factory engine harness does not need to be replaced and all critical accessories such as air conditioning continue to function. By using the optional FC COMMANDER, the user can adjust and modify a wide range of settings. By changing various parameters and data, the Power FC will adapt to any of your performance needs. Since there is no need to upgrade ROM chips or trade in ECU's, the factory ECU can be kept by the original user.

The Power FC operates off of three Main Menus. These menus are : Monitor, Setting, and ETC.

In Monitor Mode, the Commander can display up to 10 parameters of data in real time.

Monitor Mode can display:

Engine RPM

Ignition Timing

Vehicle Speed

Air Flow Voltage (Pressure Sensor Voltage)

Injector Duty Cycle

Boost

Knocking Level

Battery Voltage

Intake Air Temp

Water Temp

In addition, there are 4 display patterns allowing 1-8 parameters to be shown on screen at once. The data displays in numerical real time values with the option of a real time 10 second graph display. Peak Hold values and Display Hold functions only require the touch of a button. The Map Trace Mode allows Ghost Map Tracing of the Fuel Correction and Ignition Timing maps. This allows the user to visually see what point of the map is being used in real time. The Ghost Map Trace function leaves markers on the used portions of the map for easy reference.

Setting Mode allows full access to the 20x20 ignition timing and fuel correction maps. The user can adjust any portion of this map in 5x5 sections. Air flow correction values can be entered for vehicles upgrading air flow meters. Injector pulse correction menu is used when upgrading injectors on the engine. The Acceleration Enrichment Correction function improves response under hard and sudden acceleration. The Cranking Fuel Injection menu corrects the amount of fuel when the engine is being cranked, or when the water temperature is cold. A separate Water Temp menu allows fuel correction according to water temperature. The RPM menu allows rev limiter settings and idle RPM levels. Access menus also vary according to specialty engines. Rotary engine Power FC's accommodate leading and trailing ignition maps. Honda engines Power FC's allow for VTEC control. Complete boost control is possible by using the optional Boost Control Kit (Not necessary for vehicles that come factory turbocharged.). Changing data is easy: just access the desired point on the map or data, and push the FC COMMANDER keys in the appropriate direction.

The ETC Menu contains utility parameters such as : version information, LCD screen Brightness, and Initialization of all Data. In addition, the ETC Mode allows the user to monitor all factory sensors through one screen. This screen can tell the user if any sensor is in use or malfunctioning.

The Power FC also comes preprogrammed with several base maps. (Currently with Japan Domestic Market Vehicle Maps. Minor initial tuning may be required. Please contact your authorized Power Excel shop for more information.) This makes the initial tuning process much quicker. As with all other fuel controllers, the POWER FC should be tuned on a dynomometer by a trained professional. A high grade air/ fuel ratio monitor is also recommended during tuning to ensure best results.

      Mistakes were made, my R34 Story

      Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.

      How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP

      I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use

      I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.

      You are all good then, I didn't realise the port was in a part you can (have!) remove. Just pull the broken part out, clean it and the threads should be fine. Yes, the whole point about remote mounting is it takes almost all of the vibration out via the flexible hose. You just need a convenient chassis point and a cable tie or 3.
