S4 Apexi Power FC Harness Adapter
I have looked at the N/A wiring diagrams and pinouts. There are 3 differences pins 1R, 2K and 3D:
1R is the Power Steering switch on the N/A and goes to the knock control unit on the TII
In the adapter harness we do not use 1R, because the Power FC has its own Knock control capabilities, the knock control unit is bypassed/removed. If the N/A does not have power steering then no problem.
2K is the split air solenoid on the N/A and the twin scoll on the TII
We do not use 2K, the Power FC does not control twin scroll. In most cars we remove it from the exhaust manifold. I still do not see this as a problem for an N/A install. Most people that are to the point of installing a standalone have this removed anyway.
3D auto inhibitor on N/A and fuel pump resitor relay on TII. This simply means that you cannot install it in a automatic trans car.
So after all that it looks like this adapter WILL allow installation of a FD Apexi POWER FC into an N/A car. You wall also be able to hook up a knock sensor and have readings on the commander.
Before we can say that everything will work perfectly we need to install it in an N/A car and do some tuning.

If I was going stand-alone, there are a lot better options with better resolution available.

The other standalones are good but they all require hacking your car up. The Microtech has far to many extrapolation points that are not tunable, and the fact that I can not save a map is rediculus. The Haltech is a bit better with exception to the DOS software. I have tuned all of the them the Power FC has a 20 x 20 grid allowing for minute corrections to fuel, leading and trailing timing, along with all other parameters of the engine management.
The Haltech and Microtech are much closer to the S-AFC as far as the tuning screens go.
So you come on this thread , **** all over the place, and don't add any real input. For what purpose?
Prove the resolution is better on the Microtech or Haltech and prove they are better than the Power FC. Thousands of PFC owners will disagree with you. Start listing your "better options" with facts to back them up, not just empty, open ended statements.

Blue TII im runing a FD uim and tps on my S4TII that means that i will be using a widerange tps,but what about the people with stock tps?do they need to upgrade to and S5 or FD tps?
It depends on what you pay for the PFC. I have seen them for as little as $475 recently in the 3rd gen section used. new $690 + shipping
Our install kit $215 (current S5 price)
FD map sensor (as little as $15) or GM 3 bar around $50
FD igniter $50
FD intake air temp new $60ish

Try and ask A'PEXi about your FC3S, and they will be confused.
Try to get warranty work for your Power FC when you tell them you're trying to use it on an FC3S, and they will ignore you.
So who handles the tech support side of things? Just you?
That AP Engineering unit made for the Kouki FC3S isn't going to be serviced by A'PEXi USA, so you're SOL if something goes wrong.

That's 1024 versus 400 - almost a 3 fold increase in resolution.
Haltech is user scalable every 100 RPM.
HalWin has been in use for several years now, so DOS is limited to E6X as an option.

Haltech also has a 3D graphical map if you're into that also.
Does the Power FC do data logging?
Hell, I think even the Microtech is able to do that.
Datalogit necessary?
****, more money to spend...

I think you're conveniently not mentioning a lot of disadvantages to hype up your product?
Sure, the Power FC is about $1,000 for the unit and the Commander, but how much are you selling the adapter?
I bet it's going to get close to what a Haltech E8 goes for?

1024 versus 400.
If your Power FC owners think 400 points are better than 1024, then I call you all stupid.
I think that's an obvious difference in resolution.
I think you need to do your research, cause your information is seriously outdated.

Thanks Mr. Spell Checker.
There is no product, I have only made one of these adapters for the S4 and can trash the project at anytime. It is not like I do not have a company to run building engines.
As far as support goes, there is a ton of support the Power FC, just take a look in the PFC forum. The maps don't change a whole lot between series.
I never said this was for everybody.....
I will respond to the rest of your post when I have a few spare minutes
BTW it is BECAUSE not cause

TED, I think some people just don't want to put in the time, money and frustration that goes with installing a Haltech or Microtech. I have been researching and researching my mega squirt info so when the time comes for installation I will be prepared for the long road of troubleshooting and tuning. Essentially the Power FC is convenient- plug in play(play regarding professional expertise with tuning) but seriously lets face it, majority of people including me at times don't want to go through all the detailed shenanigans of stand alones. Most want a effecient fuel/ignition computer that requires little maintenance and will provide them access to power gains.
I wanted to do the megasquirt for a lesson on tuning and building an ECU. If no one wants to learn anything in excess detail but wants great engine management system, the Power FC is the way to go.
I know it is hard to believe but some people dont have the time to invest it all in the 7. (kind of a oxymoron since the 7 requires so much time just to stay "happy")

Does it really matter that you have 1024 to screw with rather than 400 on a street car? Ive wanted a PFC for a long time and now this harness will allow me to run it in my TII without having to deal with the nightmare of adapting it myself.
But I guess if it isnt a Haltech or has 235987324 resolution then its just a glorified S-AFC huh.

Do you think maybe you are trying to force the Haltech because you charge a minimum of $500 to install and another $500 for initial tuning? That is not even power tuning, just “street drivability”. Hell, there is a reason to go Power FC right there.

How about you include the $1,000+ price tag for a brand new Mazda OEM engine harness with the costs?
Still think it's cheaper?
I doubt it...

Just so everyone knows, we do not sell the Apexi Power FC. We simply developed the ability to use it for our own car. When I shared this information with the RX-7 community, I got swamped with phone calls and emails asking how to do it. The S5 adapter was developed due to overwhelming requests. The same for the S4 prototype.
Actually I spoke to Sumitomo today finally and they wanted a 1000 pc minimum order on the connector body and 40,000 pcs of the terminals. I am now working my way through their affiliates, to see who stocks the connector, that may be willing to sell them in smaller lots.
