right this is what i have got,

A 93'suzuki cappuccino ( stay with me peoples...) stripped out, roofless, stiffened up , welded doors n seam sealed and with a 93' fd3s lump shoehorned in the engine bay with a single turby conversion.

I bought it off a member on my suzuki forum as he sold it as a 95% finished project ( got it for a steal of a price :-).... ) he was moving house and it needed to go quick.

he slimmed down the wiring and got the car all plumbed in and running but it has a misfire , now this chap i got it from is a very knolwedgable chap but it seems he overlooked a bit of info on the std ecu's . As far as i have read up on these cars the ecus dont like much change and even though you may be getting the same psi pumped in the volume is different from a single setup as to a twin right? im thinking this is one of the reasons why the ecu is not having a good time making my death sled run sweet.

Right , after searching this that & the other i went down the route of getting a power fc , here is where i slipped up...

I was watching loads on ebay and other places etc, i ended up NOT seeing a vital bit of info on the ebay page saying that the ecu i just got was from a 96 model.

so have a laugh on me peeps i deserve it lol, but i have just bought today a s7-8 loom to go into my later power fc and plan on splicing it into my existing loom, I was planning on ( if the metal pins are the same) removing the pins from my existing ecu connector and putting them into the plugs off the loom i just bought or just getting some sort of jumper cable block which connects into my old loom connector and then using the jumper wires to solder onto my new s7-8 loom.

All i ask now is some pointers on how to get the wiring pin out data for the power fc please? i cant seem to find any on here and all i have downloaded so far is a vi-pec ecu pinout of the different series looms , im not sure if they are going to be correct as it may only list the wires they need to plumb in to suit their ecu's.

I started at the expansion blue block connector and can found that the wiring nos were not corresponding to what i have on this new loom so i stopped right there..

So long winded i know , can anyone help me please??? I felt like i should at least give a fair bit of info first to save any unecessary questions after this post etc :-)

Thanks in advance

 

Wait, what are you looking for again?

 

im after the wiring pin data for a power fc so i can label the wires on this new loom i have just purchased so i can get and idea how to mate this loom to my old one. Im guessing the wiring pins would be the same as an original loom setup as the power fc's pretty much plug in and play ? so i guess ideally i need the pinout data for the 93 and the post 95 spec too ? more i have the better i can understand lol

 

You have a series 6 Power FC that you are trying to match up to a series 7 harness?

 

Hi,

You are easily at the point where a stand alone computer that comes with its own loom for you to wire in would make more sense.

Compared to debugging something like you are trying, wiring in a computer is easy.

Also, you are assuming the cause of your poor running is due to the factory computer not liking the single turbo conversion? That *might* be a bad assumption. It would be best to first verify each and every engine support system.

Things like

Thermostat functioning
Engine at correct running temperature
Sensors giving correct readings (temperature etc)
Correct and good condition spark plugs
New or good leads
Good coils
Clean and new fuel
No vacuum leaks in the engine system between the throttle body and engine.
Clean injectors (they could be partially blocked).
Fuel filter
Oil contaminated with fuel/water
Ignition timing set correctly

I could go on...

 

yeah using a plug-and-play system on this kind of engine swapped car is sometimes a bigger headache

 

the misfire is not a constant , it starts and runs then it misfires if you rev it up or give it a handful of right foot.

The car engine itself was a runner, it was his rex and fully running until he played ballerina and spun it through a hedge in the wet and stuffed it back n front - it still ran fine after the smash. I know i have got a headache and a can of worms here but the rotary specialist near me said its possible and i have read on some page that you used to be able to get a direct jumper cable which ran a later spec pfc on a 93 loom via an adapter loom. Its gotta be a do-able thing if you can get an fc series running on a power fc with only a few mods?

All im asking is to just have a link or tell me where i can get my hands on power fc pinout data or mazda pinout data for my existing 93 loom and this 96 loom i got which plugs into my later power fc i have.

when the bloke i got it from got it up and running he used the on board diagnostics blink procedure and it didnt ping any faults in the system- I know it cant tell you if the plugs are bad / coils etc are not up to scratch but like i said it does run just not perfect . Gimme a bit of slack and point me in the right direction where to investigate and learn more ;-)

I know you may be thinking ' why doesnt he just go consult the rotary specialist ' but i just had an ankle op so mobility aint my forte at the moment so consulting the forum with an abundance of peoples input is far easier for me and it doesnt pester the specialist with my noobie questions and him possibly hating me before i get anywhere he he

 

http://foxed.ca/foxed/index.php?page=rx7manual go here and get the workshop manual. The ECU pinout for series 6 is in the fuel & emissions control section. For series 7, good luck. I've never seen anything for series 7. I have a supposed pinout for series 8 that I found on here but I am not sure how close they are between series.

Series 7 and 8 were much lower production than series 6 and were never sold in America. There is far less information available on them. I've never even seen a series 7 or series 8 even at car shows and big meets due to the very strict US import laws.

 

wired in the pfc last weekend, i got it going !! i have explained more on a thread of mine ( just updated it )
