I have a MY98 Impreza and i use a Power FC for about 2 weeks.
I am using the base map for this days and the car is making a clicking noise (like the turbo solenoid noise) when idle.
Any suggestions?

 

it is mostlikely the purge solenoid under the inlet manifold..
you can unplug it electrically as PFC doesn't use it.

If however the clicking is from the drivers side inner wing then it will be the boost solenoid but my money is on the purge solenoid.

The base map is not safe on uk fuel by the way.

Thanks Simon
I hear the sound coming under the manifold, i will try tomorrow to unplug the purge solenoid.
I am in Greece and i am using 100ron fuel.

 

your driving around on the base map!

base map is only safe enough to get the car started and onto the rollers.

 

if he is using 100ron fuel the it should in theory be okay or as Apexi intended
assuming it is an STi?

Although the map is pretty agressive.. what boost you running it on?

Simon

 

Yes it is STI and i am only running 0,9-1.0bar boost.

 

most likely find then.

Make some det cans and you might be able to run more boost.

Simon

 

oh and can you post me some 100ron fuel please

 

NOoooooooooooooooooooooooo

do not run your car on a base map

a base map is put there for the mapper not for u

simple as

phone any tuner that uses tthe powerFC they will tell you not to use the base map

anyway even if it is the same map as the one on the standard ecu than what is the point in taking the risk of using it ????


TAKE IT OFF!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! untill yopu get it mapped.
I CANT STRESS THAT ENOUGH

 

Craig, maybe a mapper has already posted on this thread! The base map is to0o much for uk fuel, however skydiver is in greece and is using 100ron fuel which is what is available in japan

 

Craig, take a deep breath and step back from the keyboard..
Jay has pointed out that the base map is for 100 ron juice and we dont get it here in blighty.
In greece they do.

 

I have a knocklink in my car and i have seen only the two first green lights in hi revs (5000>) and the knock readings on PFC is playing from 7-18 max.
I don't know anyone here in Greece to map my car and i am waiting the answer from a mapper in UK.
OK for the the 100 ron fuel, send me your address and i will post to you some

 

All sounds good..

What did the knock link show on standard ecu?

the only issue would be what AFR it is running which you cannot check with out a wideband but I would expect it to be slightly rich.

Simon

 

Before the PFC i have used a GGR ECU with the same knocklick readings, i am waiting a new sensor for my AEM wideband Gauge.
I am sure that the car is working to the rich side because i have seen some black smoke from the exchaust, i will try to lower the inj duty.

 

Sounds like engine noise only then..

I wouldn't play until you have the wideband on it..

Simon

 

You can stop the clicking by turning the 02 feedback control off. This will then run open-loop all the time.

Or set the idle fuel cell(s) to be greater then 1.047 IIRC. This will still run closed loop for cruise, but will switch to open loop at idle and in turn switch the purge solenoid off. It may run a little rich at idle though.

 

I have unplug the purge solenoid and the noise stoped.
To run more boost is the OEM restictor necessary?
