Help Running Rich - Power Fc!

[DMDRIFTING]

Hello,

if anybody can help that would be great!


My FD has just come back from a Rebuild (Street Port etc),
Power FC
Air Intake
After Market IC
HKS Slient Power full exhaust
Uprated fuel pump
HKS Twin Spark
850cc Primary Inj to be fitted
Boost Controller to be fitted


Im running it in and close to 400 miles so far, will do the next 100 tonight wahoo.

Its running a base map on the power fc

It is flooding itself every time I turn it off? I have taken 5% off the base fuel pressure @ 1000rpm, it seems better.


Anyway after returning home today from work 12pm (Seriously hot day) i stalled it :spank , started after a few turns with foot on the floor to clear fuel, I wanted to raise the revs to 4k before turning off to prevent it from flooding and as soon as it got above 3k it popped and banged like an angry gunship.

I would like to know if I can adjust the water correction temp \'80 degrees C\' to prevent this? and also could I take another 5% off the base fuel pressure at 1000rpm to help with the flooding?

What is your current base pressure on idle?

[DMDRIFTING]

Just the man, have you got a contact number to ring you on? No drama if your busy I understand.

I\'ve gone into the \'normal\' setting on the Power FC, opening the
 
 8000rpm -100%
7000rpm - 100%
6000rpm - 100%
        " etc
and adjusted the
1000rpm - 100%   to  94.9% iirc

Hey Blitzboy,

just gotta head out again now, if you can e-mail your number that would be great!


Could the ecu be in a limp mode?


Forgot to say it backs the revs off automatically above 3k

hi, not allowed to do private calls in the office im afraid.
The Apexi does not have a limp mode.

They way you would adjust base fuel pressue is the Fuel pressure regulator itself, do you have a guage on it? what does it read on idle?

[DR SCHNITZEL]

Am i right idle should be 28psi at .7 vacuum and 0 barr should be about 38psi?

Speak to your engine builder.

Unfortunately i don\'t have a gauge on it at the moment!

Will give Tim a ring tomorrow, he said it has a break in the ignition higher up in the rev range but they couldn\'t source the fault??


I was just a bit confused on why its flooding all the time!

Is this any good?

[DMDRIFTING]

Right....


car stalled on me again today halfway to work...


RAC couldn\'t sort it....


Tim pointed me in the direction of water temp...

No water temp reading on ecu, this explains the hunting/stalling etc


Has anybody got the FD ecu pin outs? Will route a new water temp wire as the original in the loom is fooked and not getting any voltage now


Much love

[BlitzBoy]

There should be an electrical section in here dude

[DMDRIFTING]

Again many thanks :Thumbsup!

[DMDRIFTING]

Ah, i\'ve got the service manual, and still after studying it for a good while a cannot find the location for the water temp sensor on the ecu pin outs???
