Hi to all

My PFC arrived today and I'm going to install it tomorrow but before are there any tricks for clear install and setup? Yes, I've read the manual but I've some concernings about the fuel octane. Three years ago I had used Prodrive ecu on a MY96 and rebuilded 3 engines in a year because of there were no mapper in my country.So still there is noone to tune PFC and I'm afraid doing smt wrong. Since the PFC tuned for 100 octane fuel I need to retard timing isn't it? Can some please inform me how to do these first steps.

I've wasted my money on hks bov and installed it today and I think it will make some idleing problems near future. Other than this I've a Blitz Nur Spec axleback so we may say that its a quite stock MY98 car. I've also ordered Defi EGT,Boost and oil pressure gauges but they havent arrived yet. I'm going to order a zeitronix or innovativemotorsport's wideband in the near future. All informations would be appreciated.

 

What country are you in? Andy F is known to be a good Power FC mapper, he could answer your questions.

 

Well said first step would be to call/contact Andy

 

I'm in Turkey, would definetly contact him if i was there. Andy Forrest may kill me, I've asked lots of questions to him before ordering PFC I'm searching google and reading all documentaries I can find now and thats the only thing that i can do now.

 

im sure at a cost andy will fly out to you why not send a spec sheet sheet to andy and a cheque lol for him to do a safe, ish map for for you till you are in a position to get something done properly

 

I pluged it today and it didn't worked I think there are some wirings to work on it ... Everything seems okay when the ignition ON but when I start the engine I understood that fuel pump is not working. Even in ignition ON it does not pump the fuel. Looms are ok! I think I should call Andy.F before firing PowerFC

 

"I should call Andy.F before firing PowerFC"

Not a truer word said

 

Maybe
'i should have bought it from andy before calling him'

Unless you did of course.. then call him and pester the hell out of him

i think most people that put PFC's in have to do something with fuel pump wiring.

I'm not sure what the problem is, but they dont seem to run the pump on Scoobs!

 

Yes I knew that it was a wrong word but couldn't find the right one May be melting,burning? I think burning...

Scoobyduck yes there is probably something wrong with the pump but to solve that problem I need to find the diagrams for the PFC that I have and MY98 ECU pinouts. Somebody must know that wiring

I think it would be easier to find Andy's phone number. Anyone got it? I'll not tell your name and pester the hell out of him :P

RX7 community have a lot of information about PFC but does not solve my problems.

 

fuel pump is
B137 pin 17 (with immobiliser)
B137 pin 7 (without)

the apexi requiers it as the JDM cars are wired, which is in pin 7
but it still didnt work!

if its a euro spec car, then you will need to swap the cam & crank sensor connections too.

Steve

 

Do you have the same problem? Yes it is euro spec car and I have no immobilizer too

 

yes.
MY98's should have a factory installed imobiliser. not sure if ALL euros do tho.
Check if there is a wire in B137 17 or 7.

I have run the fuel pump wire directly to ground. this works - but runs the fuel pump all the time the ignition is ON. which is ok but dont leave the ignition on long!

 

******if its a euro spec car, then you will need to swap the cam & crank sensor connections too.*******

yes, this is something Andy did to my car before starting mapping.
sorry cant be of anymore help other than Steve's suggestion above about a spec sheet and try to get Andy to put a safe map in that you could then tweak (via the commander)

 

I don't know what is wrong with scoobyducks car but on a JDM of this year, the Apexi ECU is plug and play. On 100ron fuel the base maps are not too bad either !
On a UK/Euro then the 7/17 pin swap plus cam/crank sensor swap will get it running....of sorts.
The UK/Euro 97/98 will run way too much fuel and too advanced ignition on the original Apexi maps, you would be quicker and safer on the std ECU.

As suggested, I could install a 'safe' map on your ECU via post but it would be exactly that, safe. Not fast, not economical, not optimised to your car and not much value to be honest.
You really need someone to look at it who knows what they are doing.

Sorry I can't be of more help.

Andy

 

You and me both Andy !
it just wouldnt run the pump. am wondering if its faulty on the pump driver. ever seen that?

Sonica - my recommendation is to get someone who has some mapping experience (not necessarily Apexi) to tune it. or, get Andy to put a default map in, and then you can tweak it. or pay for Andy to have a nice holiday!

 

Thank you all for your helps. I get a bit disappointed with PFC now Of course I wish to pay Andy for a nice holiday in Istanbul but I can not. I'm not sure what to do now just driving my car home-to-school. I did not except to be quicker but at least safer.

Anyway thank you Andy again.

 

if your only after a safer map to allow you to run the pfc then Andy has said he could do that for you via post.
it would at least get you up and running.
you could then read up on mapping and make small adjustments until you get somewhere near what your after.
not ideal but it may be necessary.

 

Peanut I could not have succeed on fitting yet. I think wirings are different because Pin7 is empty.

 

In the end it works! Everything seems okay for now. Car is a bit slower than stock for the present. Knocklevel did not exceeds 7

Here is the information, just for sharing
Plug A(b137) Pin17 to Pin7 (fuel pump)
Plug C(b136) Pin8 to Pin10 (cam&crank exhange)

I'd like to thank Steve ( Scoobyduck) for his great assistance!

 

Hello Sonica

It seems we are sitting in the same boat, no PFC Mapper here in Switzerland, same car My98.
I did buy the Zeitronix unit now which is great to map the inj Map. However for the ign Map it seems a bit harder! Is there a general rule like 1 degree per 1 Ron or something like that??

Cheers, and my adive to you, don't give up! Together we will do this thing ; )

Chris

Did you order the FC-Datalogit Software? It should also help you to tune your PFC easier.

 

Hi Chris,

Yes, same boat and same route Yesterday or the other day I ordered Zeitronix too, it must be on the way. Actually I did not make anychanges on PFC because I wanted to wait for zeitronix and some defi gauges. At the moment, I'm driving with the stock ECU.

For now, I'm reading everything about the PFC tune tips. I was advised to retard the entire ignition map by -6 for 98 RON fuel and than start with small changes between cells for safe. Scale MAF to %78 on 8 points.

I haven't ordered FC-Datalogit yet, I should save money for it and a knocklink also. Have you achived any goals on PFC till now? My car was slower on a PFC with the base maps how about your car now?

Good Luck Chris! I wont give up, I like it very much

 

Hello Sonica

I haven't seen this message till now!! Did you get your zeitronix unit??
I have ordered my FC Datalogit about 2 months or so ago and haven't heard anything so far : (
My REX was also really slow at the beginning due to the high AFR. Thanks to Andy I could fix that. If you need help PM me.
Which Values do you use for loging the Zeitronix?
I managed to get the RPM, AFR, Lambda values. The boost seems to be hard to get! Moreover it has the wrong unit - not mmhg and kg/cm2
If you know where to plug the boost let me know - it doesn't work on the map sensor though - tried that already.
It seems that we need that optional boost sensor with it : (

Where did you plug the lamda signal from the PFC to? I plugged it straight to the zeitronix narrow band output but it seems strange to me as my apexi turbo timer can't read the lambda signal from the zeitronix unit which it should be able to.

Cheers Chris

 

Hello Chris
Yes, I got it yesterday or the day before but I couldn't install it yet due to the time insufficiency. Today I just work on installing my new gauges. Actually, I did connect the wideband wires(RPM,TPS,Power,GRND) but couldn't check if it works or not. On Monday, while tapping a hole in the header for EGT, I'll also tap a hole for the O2 in the downpipe and will check the wideband. What I'm thinking is that if connecting defi egt probe to zeitronix egt input would effect the accuracy of the unit itself.

PM'ed you.

Cheers Cuneyt

 

The same problem...

PFC, no mapper in my country (Spain), same car.. GT98

now working better, thanks to singang!

 

I just got a an email from the FC Datalogit guys, they sent my controller : ))))))))))))
What a great news!!!!!!!!!!!!

Funny 3 stupid guys from Europe with now PFC Mapper at the same time ; )
On the 13th of January I am heading to the Tokyo Autosalon 2005 - think I need to have a longer chat to the Apexi staff overseas manager *ggg*

Cheers Chris

 

eheheh I've a MY98 also and I think I'll be the first to blow the engine but happily we can make a 2.5l group buy

 

or the second

My old engine...

 

Hahaha....so funny ; ) can't stop laughing : )
Today I fitted my fuel pressure regulator. I set the fuel Pressure with the manometer and finally went for a test drive with Zeitronix for the AFR check. I was astonished! Lot more power at high RPM!! Seems I am getting even closer to my aim : )
The best is that my AFR is still on the rich side : )))

Cheers Chris
