Hi All, After 8 years of 240 ownership and multiple 240 rescues along the way I've upgraded to an 850 T-5R. Big drive home from NSW yesterday but it gave m...

Hows the tune going ?
Surprised no one else has tuned in on this .

Are you still on standard injectors ?
How's your air/fuel etc

I've got o full set of white and blue if needed .

Tune is going great. The guy who tuned the ECU (voldat) said it's OK to just plug into a stock T-5R. He did some vacuum checks to ensure my system was OK and then gave it the tick of approval.

It's going great and has a serious jump in power.but I'll be keeping an eye on things and see what bits I can replace as preventative maintenance.

I must research the injectors colours/ meanings. What do you run or what price are they?

rado

I'm on green injectors with my tune . Do see 18 psi from time to time , others here do to more than 20 etc , probably worth getting a boost gauge mate .

morch_66479

rado Mine seems very conservative at 10psi on this gauge or do i factor in atmospheric pressure or anything like that? Silly question but worth asking haha

ENGINE OIL:

I serviced the engine over the space of 2 days in the following stages:

Day 1:

After a decent drive to heat things up and slush things about I added Liqui Moly (LM) to the existing oil and drained along with the oil filter as per instructions

Oil came out pretty dark, so I used some spare new Nulon 10W-40 oil I had on the shelf to refill the engine & fitted new genuine filter.

Day 2:

Had a fun drive around country Victoria, came home and immediately drained the oil and filter, refilled with new LM oil

Image description

One day old Nulon on right and new LM on left 😊

TRACS/ABS Continued:

All error codes have been wiped and system seems happy but I must check that the ABS is working somehow. On a closed road of course!!

The sensor clean and brake pedal position sensor replacement seems to have done the trick 😳💪

SUNROOF TRIM:

the previous owner managed to get a stock 850 sunroof interior trim but it wasn't flocked. Turns out all 850 T-5R trims are flocked from factory so I had mine dropped off to Flock Finishers of Dandenong. I'd highly recommend them.

CD CHANGER:
Installed a period correct Compact Disc Changer sorted out the factory fitted wiring harness right back to the radio. Also had to adjust the internal anti shock spring orientation to suit the horizontal mounted position. It was previously set to the vertical mount orientation.

Now to fit the Amp bracket, and amp.
Does anybody know if the SC-815 accepts a Dolby unit that also plugs into the AMP port at the rear of the radio?

rado

What's a Dolby unit ? Not heof that one . Excuse my ignorance..

morch_66479

rado

Just figuring it out myself but it plugs into some radios and enhances the sound some how. I just need to figure out whether it works on my SC-815

Maybe I'll just get one and plug it in to see what happens. Haha

What does your audio system consist of? Have you got a amp and what changer did you say you're using?

Edit: I remember you have the amp I'd like in my own car (6816302) so just need to find one.

rado

morch_66479
Sorry for the late reply...... when I got the car it had an after market Philips DVD double din and the loom was all spliced everywhere , since then I've gone through 2 clarion and one alpine HU's . Now I'm running the oem HU into an aftermarket 5 channel amp that's Bluetooth compatible . Quite handy having the Bluetooth for Google maps.
The cd changer is oem in the boot on the left

TL_V70

Remove your radio and see it has the connection on the back. Its designed to work with the centre speaker in the V70/C70 range. It doesn't do much unless you have the centre speaker.

Dolby unit for reference.

morch_66479

TL_V70 ah OK, that makes sense then.

I'll grab a amp instead as I don't have a centre speaker. What does the the Dolby connector look like because it looks like it plugs into the amp port?

Would you happen to have an amp for sale?

TL_V70

From memory the connection is similar or the same as the 6 stacker port. I am pretty sure it had Dolby stamped into the metal on the back of the radio.

No sorry I don't have an amp forsale. Check under the driver seat I am pretty sure thats where they live. If the car had premium sound it should be there.

morch_66479

Yeah, the dolby connection looks similar to the amp connector which is different to the cd changer connection? I think!!

So the amp was mounted behind the radio on this model, c70 and later models was under the seat (from my reading). Now to find an amp!! :-)

PARTS COLLECTION:

I've been piecing together headlight parts:
- Wiper kit
- Electric headlight adjuster (not even sure if the wiring is in the car to make this plug and play? - I'm assuming No)

Volvo Guard 2 parts:
- Pretty sure i just need to get fobs & program it to the black relay i just purchased
- Horn and dash sensor on their way.

Is that with the standard ecu or the new one (tune) ? Does seem a bit low even for the standard .. how's your wastegate actuator rod ?

morch_66479

rado

It's the tuned ECU

ok, I need to dig deeper and get a better understanding of what's going on and what I may need to check over.

Feels good, pulls really strong so I was surprised with the 10psi result 🤔

What should I be looking for regards the waste gate rod? Guessing no slack?

rado

Yep basically no slack , just don't adjust it when it hot as not much room down there .

morch_66479

rado
I checked the rod and feels tight but i think a proper test is make sure the diaphragm isn't leaking and also setting it properly using a pump?
