As many of you may know, we installed an FD Apexi Power FC into our project S5 Turbo Vert. We received calls and emails from many individuals asking us to develop an adapter harness for easier installation. We considered the fact that not everyone wants to permanently alter their engine harness, and/or take the risk of making a mistake with one of the wires that needs to be relocated. Long story short, we went ahead and developed a Harness Adapter Kit that makes the FD Power FC truly ‘plug and play’ for the S5 TII. One of the additional features is that the modification can be reversed, allowing the car to easily return to the stock configuration.

We have set up a special pricing webpage for the initial release. These prices will only be available until February 17th. After that date, the link will redirect you to the regular product page. The initial release pricing reflects a $10 discount when purchasing the ECU Harness Adapter only, and $15 savings on the Harness Adapter Kit which includes:


S5 FC3s APEXi Power FC Harness Adapter
GM 3-Bar Map Sensor Harness Adapter
FD Intake Air Temp (IAT) Harness Adapter
Base Map

This is an amazing offer, Im so jumping on this.

 

Any chance of you offering an adapter for the ignitor?

 

We are working on it, just as soon as we have a source for all the connectors it will be available.

Also the kit price reflects a $20 discount, that was our mistake but we will leave it until the 17th.

 

Im buying a kit as soon as I get paid next week.

 

Fantastic stuff! Hopefully we'll see some FC guys in here with PowerFC's .

Just ordered my Power fc. YAY!

 

Great!
I guess there will also be a S4 version.

 

Yes, we are working on the S4 version now. Hardest part is sourcing the ECU header connector. We already have the diagrams made up that reflect the changes needed.

 

So the next question is... where's the best deal on a PFC these days???

 

I would have to say Jap parts specialists at $690 + $40 shipping http://www.jappartsspecialist.com/

Which is the same guy that sells them on Ebay for $699 + $50 so you are better off just ordering thru the website.

 

what a fantastic setup!

The japanese when they built my car (built is a lose term) bastardized a series 6 wiring loom to work around all the bits that are not on a s5. Fondly enough this is also a series 5 vert'!

If only this came out 2 years ago! Awesome work guys

 

now you are refering to the chassie side harness when you say s5 right. because i am about to get a 88 gxl that has a jdm cosmo turbo motor with a single t70 turbo. And if i get the full PFC this will control ignition timeing too right.

 

In a short amount of time we will have an S4 adapter harness available. The S5 and S4 are very different. With the S4 adapter you will be able to run an S4 TII (or N/A) engine harness and S4 chassis harness.

 

I will probably start a new thread, but the S4 adapter prototype is complete. We just have to install it, do some testing and tuning and it will be available.

 

Keep us updated. I am eagerly awaiting the s4 product.

Question... would you recommend buying a brand new FD air temp sensor from Mazda? Do they tend to go bad, or could I get away with a used part? I don't want to halfass it but I don't want to waste money either. Also, the ignitor. I don't know much about FD ignition. On an FC, there is the coil + ignitor for leading and another coil + ignitor for trailing. What exactly do we need?

 

You can buy a used intake air temp sensor, but if you call Ray at Malloy Mazda they are not very expensive new. For the FD ignitor install you are keeping the FC coils just bypassing the igniters. Here is a complete How to:

We are trying to source the connector it is made by Sumitumo, but they are slow to respond with any pricing. If we can get a reliable source we will make an ignitor install harness, then the whole conversion would only take about an hour.

 

When you say use shielded wire... where can we source this? This isn't regular radioshack wire right? I'm just trying to understand everything in this writeup. My only experience is installing an MSD on a leading coilpack on my nonturbo.

 

You can buy it at Radio Shack or pretty much any electronics supply store. A 50' spool is $5-$10

 

keep is ipdated on the S4

 

Here is the link to the S4 thread https://www.rx7club.com/2nd-generation-specific-1986-1992-17/s4-apexi-power-fc-harness-adapter-626279/

 

We now have MAP sensor harness adapters to mate the stock wiring to the stock FD and Apexi 3 bar sensors without any cutting.

 

Just got my kit in the mail today, very good quality on the worksmanship. Cant wait to get everything installed.

 

If you have any questions during the install, feel free to email or call the shop.

 

Im still working on gathering all the parts, so it will be a few weeks before I do the install, but thanks.
