This is long overdue!!

Here is my '96 Type-RS weekend/track toy. I've owned it 3.5 years so far.

The Type-RS has additional goodies over some models

• stiffer dampers
• momo steering wheel
• 4.3 final drive
• tight type lsd
• 17" enkei wheels
• 314mm brake discs
• 280ps

At the moment it has a few basic mods/upgrades

Recaro drivers seat



ARC Airbox and ARC Super SMIC(double stock thickness)



RE-A Gearknob, RE-A boost gauge mount, period Greddy boost gauge



Mishimoto Radiator



HKS Twin Power



Knightsports AST



Dixcel 314mm Heat Treated discs and Extra Speed Pads





Exedy Stage One Organic Clutch

 

I've done a few track days with the car.

Brands Hatch (twice)



Bedford Full GT Circuit (on a 30C day - highlighted the need for an upgraded rad!)













Cadwell Park (AKA mini Nurburgring)

 

The plan for the car had always been OEM+, i.e. retain the stock twins and do small upgrades over stock to make it a reliable track car.

This morphed somewhat after at least one solenoid failure per year since owning the car.

The last failure happened whilst on track at Cadwell causing me to lose all boost on the secondary turbo roughly 3 hours into the day and resulted in me heading home dejected at lunchtime.

So, retaining the stock twins went out the window, and more goodies were purchased

Turblown EFR 7670 IWG cast manifold kit





Greddy V-Mount Kit





SMB Twin Pipe 3" rear section







Still to be purchased

• fuelling parts
• ECU (most likely adaptronic modular plugin)
• midpipe
• ohlins
• bushes
• 4.44 Final
• poly bushes, engine mounts, diff mounts

The car is still on her original paint, and whilst it scrubs up OK it wants repainting, all the corrosion sorting, and the underside treating to make it rust proof.

I'm likely to repaint it a metallic green, possibly BMW Oxford Green which looks really dark unless the sun is directly on it

 

Looking good!

 

Great car, one of the first to have the 17" brakes.

That ARC intercooler is one of the best you can get, that ARC induction box however is one of the worst it pulls air strait from your radiator, stock intake would be a serious upgrade.


"[*]ECU (most likely adaptronic modular plugin)"

I want one of those as well, you are in the same boat as me though, the JDM 96-98 FD3S-4XXXXXXX does not have an adaptronic available. Matter of fact I cannot get them to acknowledge that we have the 16bit harness so I just gave up. Maybe some day I will track down the pin out, translate it, and publish it but have not found the time.

 

I'll be fabricating a cold air pickup when the turbo and vmount go in

I had no idea the intercooler was well regarded, to be honest I had no idea ARC did a double thickness SMIC till it appeared for sale on the UK Forums. I'd seen the Trust and RE-A stock mounts.

It's a bit beaten up to be fair.


Yep... my vin is FD3S-4. I had no idea that they didn't make one for our car! Fsck....

How/when did you confirm this with them?

Maybe Power FC it is then.... I bought a PFC+Datalogit about 18mths back, then sold it as I was set on the adaptronic. At least I made a profit on reselling it...

 

The most highly regarded SMIC unicorn, MAZDASPEED, was made by ARC only difference is cosmetics. They are both a big deal.

Their website says you can use the same adaptronic on 1993 to 1998... Considering that the harness changed to 16 bit in 1996 that does not work out. Even though they are both the 16Bit harness, you cannot use the 1999+ ones either (aka "Series 8" a designation completely made up with no basis in reality for wikipedia...) because the pin out is different.

Do you have a link to the pinout for your car ?

 

Ok - I got what I feel is non-comittal reply from Adaptronic overnight. I'm not filled with confidence.

Basically suck it and see, maybe an agreement to refund if it doesn't work.

 

Apparently this is it

Comparing that to the Adaptronic supplied RX7_S8_Sel_pinout.pdf, it seems to match the S8 adaptronic plugin ECU pinout

 

FD-RX7 Enthusiasts Forum

Also here, pin out for version IV - VI seems to match S8 pinout from Adaptronic.

 

I think the S8 plugin is the one for my car afterall

There's a guy on the UK forums running the S8 ECU on his 97 RS so it should work on mine. I think.

Guys on the Aus forum seem to think the only wiring difference is AC fan control

 

Hi Marf,

I apologize for the confusion but this is rather simple. Please email me a picture of your stock ECU connector. Its either going to be an Adaptronic Series 6 ECU or a Adaptronic Series 8 ECU. My email is shawn@turbosource.com

Thanks,
Shawn Christenson

 

Hi Shawn

Thanks. I will whip off the ECU panel on Saturday and snap some pictures.

Thanks for your offer to help

Cheers

Marf

 

I went line by line and that wiring diagram posted in the above link is identical to an S8 Adaptronic PNP.

If you open Wari, then load the S8 base map, and open wiring pinout you can look at the wiring diagram( same goes for any unit).

As you can see here( I only uploaded the 1st connector) they are identical. So if you're plug looks like this Marf you need an S8 PNP.

One of Adaptronic's tech guys( mark) has tuned few of these S7 & S8 cars too...

 

Thanks Elliot. I had a cursory glance over the first 4/5 items for each plug at work when I posted the links, but didn't get a chance yet to check the rest.

Storm in a teacup then, thanks all

 

It is not simple... There is enough English on this page that you can get the idea.

A'PEXi - ?????? - ???FC???????????

Apexi had the 96-98's separated from the 99+ models, they said it is because of fan control. Which is no minor detail.

I would not bet the farm on that link being 100% accurate. My friend has a digital copy of both electrical service manuals I will try to get them from him and translate but it is going to take me quite some time.

At a minimum I would watch things very closely, especially your fan control.

 

The HKS Fcon harness is the same as 96-02 but it is just a piggy back.

New purchases

RX7Store Midpipe

Resonated Midpipe 93+ RX-7






Innovate LC2+sensor+serial patch cable

 

Right then

Here's my ECU plugs(and my unholy army of the night)



and here are the plugs connected

 

Series 8

 

As I suspected. Thanks Shawn.

 

So my rear dampers are shot to bits. I cannot justify spending out on a set of Ohlins right now, so just picked these up from Japan




Bilsteins taken from a 2000 RS model. They've covered around 15000km

 

I've got these one my 96 RZ they ride great.


also for the ECU issue im not sure how adaptronic deals with it but the 96-98 powerFC does not work on 99+ just tried it last week on a friends car and car would crank but not start up. plug back into my car car fires up just fine.

A'PEXi lists the exact same manual for the 96-02 so im not sure if thats a thing.
