Hi to all... i will come post here because i have a serious problem (but sorry by advance for my bad english, i come from switzerland and i'm not so good in english)

I have a problem with my97 impreza... since 3 months i have started the modifications on my car and i have fit the following parts :

VF35 Turbo
555cc Injectors
255lh Fuel Pump
Silicone Turbo Inlet
Aeromotive fuel regulator
NGK-R Iridium Plugs(cold plugs platinium)
Front mounted intercooler
HKS airintake kit
Ninja Downpipe
HKS Ex. Manifold
HKS Catback
HKS Up-pipe
Apexi Power FC

but now the problem is... i can't start the car because i have an overfuelling problem... the fuel regulator has the pressure at 30psi when starting the car

anyone know the problem?? because always overfuelling and can't start my engine... and i need to remove the plugs always and wait more than 12hours to try one more time... always no success..

anyone can help me? i need to start the car to put my settings and try it!

don't know why i have too much fuel...

anyone know how to de-overfuelling the car (sorry don't know the good term) more fastest than remove the plugs and wait??


Thanks for you'r help

 

when was the last time the car started? Did you do all of the mods in one go or in stages? did you check the car started/drove after each stage. Have you tried the original ecu in the car to see if it starts with that?

 

have you compensated in the PFC for the larger injectors? try 78 as a starting point.

Simon

 

The car has now started

but i have another problem...

i have no ignition with the PFC... so i have now the original ECU and put the fuel pressure at 30psi...

i don't know i have to change some pins on the ecu harness i think but i don't know where i have to change... anyone can help me?? how to modify the ecu harness to put the PFC (Switched cables??)

thanks

 

if it is an EU car you need to swap the cam, crank and fuel pump relay pins.

Many thanks i have make a mistake

 

Will PM you some other info.

I also have a map which may help which I can email.

Thanks
Simon

 

many thanks again

can you tell me the number of pins i have to change

B136 and B137 but the pins number i have to change?

thanks again

 

B136 swap 8 and 10.

B137 fuel pump is either on 7 or 17 and needs moving to the other position..
iirc it will be in 7 and need moving to 17.

Simon

 

But on the ECU Pinout pdf sheet i can't see pins 8 and 10 for the crankshaft and camshaft right?

it's right for sure?

on the sheet i see 1 and 2...

thanks

as for the fuel pump... removing the pin 17 to pin 7 right?

 

1* and 2* refer to the notes at the bottom of the page.

100% sure 8 and 10.

Move 17 to 7 if it is in 17 or 7 to 17 if it is in 7.. you can check by turning the ignition on and see if the fuel pump primes as to whether the fuel pump relay pin is now correct.

Simon

 

Thanks... but the problem stays

always NO ignition... whyy???

i use the original map on the pfc and not changed... only the injector %...

i have to change any other thing??

i need a map but here in switzerland there is no person know how to map the PFC...

 

Car is again overfuelling... but no ignition... only fuel

 

it just turned over?

you sure you swapped the right pins?

Simon

 

Yes rights pins... pin 17 to pin 7 for the fuel pump

and pin 8 to pin 10 exchanged for the crankshaft and camshaft...

whyyyy

Have no ignition and the fuel regulator at 35psi... and injectors open at ~68-75% or more... cannot start the car... we have try with a plug outside and no ignition

 

I'm waiting for a map from flat4online (But dunno who map for flat4 i just know he don't make himself the maps)... but i'm waiting for few months now...

 

if does not sound map related..

check and double check the wiring.. you are looking at the plugs from wire side not pin side yes?

Simon

 

At the Spark plugs i check the ignition... remove a plug and look at the plug when i try to start the car.. so i have no ignition on my car... dunno why... i have checked the wiring.. pin 17 to pin 7 i can hear the sound of the fuel pump it's ok.... but pin 8 exchange with the pin 10 doesnt work... i can't start the car...

my impreza is a MY97-98 model and AD200 original ECU... dunno if i have other pins to change....

it's so difficult to connect the PFC... i have no ignition dunno why...

and can't find any topic on the net... maybe the UK models and EU models are not the same for the pinout but i think yes...

 

I believe the wiring is the same EU to UK..

only other info I can give is the cam and crank wires are red and white from memory and on the 22way connector..

Simon

 

Yes red and white... i have change the good wires so dunno why have no ignition

i have no way to put this damned PFC on my car lol... all thing i make to try and have always no ignition... all is right so dunno why lol

i will come in UK with my car and look with you for the mapping and for the pfc

but 1000km's lol

you dont want to come in switzerland for a mapping day? lol

 

lol..

have you tried not swapping the crank and cam sensor wires?

Simon

 

No, lol, i will try

 

fingers crossed!?

 

Now Dunno... always overfuelling... always same problems... FPR at 30 to 40psi to start the engine... but always overfuelling... i think it's the 15th time i remove the plugs and wait a night to de-overfuelling the car...

The car will not start with the apexi...

and now the car will not start with the original ecu because of overfuelling...

i have put now 440cc injectors and connect again the Original ECU... but always overfuelling lol...

need a scooby specialist here in switzerland... anyone need a free trip to switzerland to map the pfc and make anything?? the goal : drive my impreza with the modificatons lol...

i have all the equipment to improve my impreza... a big garage - tools - lifts and more... any specialist interrested? lol



(sorry again for bad english lol)

 

mate i just had same problem change your plugs to bosh super4s i had the same as you and they were always dieing just try it

 

Fixed

ECU Wires problems!!

but my offer is always ok for any specialist lol... need a guy to map my pfc

 

well done.. couldn't see it could be anything else.

I would love to be able to come over and map it for you but I just cannot spare the time to fly over with a young family..

I am fairly sure there is someone mapping Scoobs in Switzeland.. just not 100% sure they are doing Apexi.. will check into it.

Simon

 

No Problems

Maybe with Andy F... a friend maybe can try with him and ask for coming...

he's making a Monster Impreza GT with STi7 engine for racing... and maybe he need a good mapper again but don't know when..

anyone know a good mapper here in switzerland`? lol
