Didn't get a chance to go to wreckers to get
A tps, will the sonata ones work? They look
The same. I got few tr magma ones here but
They have 4 pins(for memory) instead of the 3 like the oz
Spec vr4 tps.

Wanna get new one cos around the top
Mounting screw the plastic has been broken off
And if its like the isc motor it'd be full of oil
Too like the rest of the throttle body. I should've
Split it and cleaned it all properly :( first

Will try this weekend. Mechanic is too busy
To look at it anyway. So got a chance to have
Another play this weekend I guess.

Hey all,
Has anyone worked much with fiavs
On oz spec throttle bodies?

Do you have to replace the whole bottom
Part of throttle body? If so any more
Common cars use the same bottom
Half of throttle body?
Or can u replace the fiav itself. Thanks

This car is really starting to pee me off.
Spent so much time and money on it and
Still can't drive it. And it's coming up to 2 years
Since I bought the shell.

And my mechanic is busy. And I want it back
On the road before end of year.

ok today i decided to play with a spare TR Magna throttle body i had
Image
i split it in half and inspected the bottom half of the throttle body.
Image
Image
I went through the magna manual on testing the FIAV, i heated it up with
hair dryer and saw it move. and when it cooled down saw it move back.
it did say in the test procedure to blow air through it and check it opens
and closes but i don't have a tiny little right angle fitting for air compressor.
but the valve moves so i guess this magna one is ok

then with great difficulty once again removed the throttle body
lots of swearing and coolant everywhere again,and have to clean all the coolant of the new paint again :(
Image
Image
i also split the aus spec vr4 throttle body, it was fairly clean inside i was expecting more oil.
low and behold someone had blocked off the Fiav port with rubber hose, come on :/
guess that explains the bit of rubber in the ISC port also. homemade ISC and FIAV Block off plate.
surely there not that expensive? :/
Image
anyway i heated the aus spec FIAV up with hair dryer, doesn't move so confirmed its faulty.

now the "homemade" FIAV block off explain the difficulty in starting when car is cold as everyone
who puts a fiav block off on says (the downside of one).have to help it idle till warms up ie have to
help it with the go pedal.


but doesn't explain when warms up 1500-2k reving itself violently up and down.
as what happens with a faulty FIAV apparently but it was blocked off hmm maybe the hose was still letting
air through???

any way the two bottom halfs of the magna and aus spec throttle bodies look identical
Image
(auspec on RHS)
also roughly measured port hole sizes seems the same. so im thinking of using the
magna bottom half on the aus spec top half. i would get a block off plate. but wanna keep everything standard
dont wanna be knocked back again.
the only difference i can see is the front coolant pipes of the magna one is one a weird angle and
not straight like the aus spec ones. bending or cutting modification should fix this hopefully. although
they are in the completely wrong direction :(

also can the fiav be removed? looks like a welch plug looking thing around it, how do you remove? and
reinstall without leaks? think using magna one is the easier option hopefully

can anyone confirm the two bottom half of the throttle bodies are the same internally?

today cleaned the magna bottom half up
Image

removed the hoses, dammit the coolant lines are so corroded
cleaned up as good as i could for now only need temporarily
Image

compared the sonata tps with the auspec one
look the same, roughly measure the same resistance wise also
(auspec on the right)
Image
Image

fitted the sonata tps to the top half of throttle body
Image

looks like i need a new gasket, both the magna one and auspec
are nearly gone on the cooling ports.
Image

also wanted to replace the biss screw but wound it all way out but
cant seem to fully remove it.

ok so early last week i ordered a few FIAV rubber gaskets, couldn't
find a aftermarket type, so had to get mitsi genuine
Image
Image

fitted the the new FIAV gasket
Image

Whacked the TR magna bottom half of the throttle body, with
the working FIAV
Image

i knew the coolant pipes would be a problem was hitting egr, so couldn't bolt
to the plenum
Image

so had to cut it shorter, because very hard to bend without kinking.
i just hope it doesn't blow off under pressure, because theres no lip on the pipe
now :/

set the sonata tps, 10percent at closed throttle - 500mV (0.5v)
Image
checked full throttle was about 5v- yeap(god my engine bay is a mess wires, vacuum hoses ev where, gotta tidy it up)
Image

whacked it all back together again

tryed starting, wtf went straight to 4500rpm
throttle cable had slipped off and jammed, so throttle wasn't closed properly

idle seemed to be ok till warmed up the did its 1500-2000 rpm surge, up and down up and down.
then thought id tryed swapping those green and white wires on the ISC motor, because put it back to
the jap spec wiring. hmmm think its ok now, prob didn't need to do all that stuff. grr oh well helping me to
learn i guess. fiddled with the BISS screw a bit too, to get it idle bout 800-900. and when cooling fans come on
drops to bout 750rpm.
Image


I will start it from a complete cold start tommorrow, and check again hopefully i have finally got it :/

Did you get that "thank f*cking god that is done" feeling when it idled at 800? the way you are trudging through all these little issues is a testament to cordias and the resilience of their owners.

No matter how many times you want to through in the towel, you just keep on spinning the spanner and eventually your in the hills pulling 2nd and steaming up to the top of the mountain :)

Nice one Marc........but I would be checking your coolant temp.......from the photo it's showing over 3 quarters!

You were right to swap the wires over on
The isc motor. To match the auspec.
I swapped em back to jap after my first try at starting
Didn't work. Prob cos the fiav port was blocked. Making
Cold starts hard. So prob didn't need to do all
This lol.

Yea prob got a bit of air in it. That's
Usually when the fans kick in. Would the
Temp sender of vr4 be the same resistance
As the original cordia turbo sender? I had
Same prob when put the tr magna efi
Set up on my sigma. Was diff resistance and
Was showing a lot hotter than it was on the in dash gauge.
That's why I got an aftermarket gauge for that car.

Tried a stone cold start. Just before. Revs around 2k
When dead cold, then down to 1.5k
Then when warms up goes to normal idle
Looks like that fiav is working right.

The king springs where right on the 250mm
Limit and one side was below that

Now she's
Sitting at bout 270mm approx just to be safe
For the inspection.

hey man, i think your right, she is getting bit warm, looked at my old vids of blue cordia
sitting alot cooler bout quarter of way , normal operating temperature?

did your engine get alot warmer after you reconned it, bare in mind done pretty much no km's
apart from what was done on the dyno, do reckon its cos it hasn't been run in.

too me it seems the fans come on too late, just wondering if the little thermo thing at bottom of radiator
can go faulty, i might try the one out of the blue cordia radiator (means loosing coolant again lol) as i used brads radiator as was in better condition core wise.
did he have any cooling issues?

Marc,
The sensor can be faulty especially if it's covered in encrusted coolant, the engine may also have air in the cooling system allowing a higher temp, just a matter of removing the cap, running the engine until the thermostat opens....top up, replace the cap and top up the overflow and allow to cool. Next day you should see the level drop in the bottle......if not replace the cap.

My engine doesn't get hot at all...........runs at 1/4 and the fans activate at 1/2. (for the AC 62).......the VR4 is custom set by the wolf but the fans only blow for 10 -20 seconds at the most. :)
