So... I'd figured I'd post something..

Since I cant seem to find a tuner I've decided to learn how to tune myself..
For last few months.. I've been "mastering" Vipec/Link ECU and tuning techniques..

Overall concept seems relatively simple..
1. setup your knock and make sure its working properly
2. tune the fuel map for proper AFR
3. finally tune ignition for power

So far its been ok.. did few pulls in total, trying to get the AFR in line..

Here are the last 2 pulls exported to a Virtual Dyno..
Wastgate pressure about 14.7 psi..





And a 2nd run

Tuning is something I've always been super interested in and how you broke it down just made a lot of things click in my head lol I don't know why it took so long to figure that out.

Is the tune analysis software useful?
I use megalog viewer (full version): 3 axis scatter graphs for eg spark table are grouse

Once setup properly the Link log analysis seems to be very good.
You can trace back and forth through and see exactly how each table was used.

I've watched few vids on other engine mgmt software and not because I have Link, but I think this one is one of the better ones.

Started playing around with wipers and making them work with the PDM..


Once I figured out and tested how the park function is supposed to work I think I've burned out the "parking tracks".




Flushed the tranny and rear diff and now filled up with them Motuls synthetics...

Last piece of "synthetic" puzzle..
Finally switching from conventional.



Sometimes I wonder who the genius was that overtightened the filter...



I always fill the new filter with oil..
Here is how much the filter actually takes..




And here's whats up next..

As the weather cooled off a bit..
to about 86F inside the garage, it was safe enough to do some work.




Pretty much all scales except the RR were within 0.2 degrees.









Looking at the scales the car has not lost any weight since the last weight in.



Yeah.. with me in the car.. looks like I have not lost any weight either...
Now.. starting with 52.50% cross weight balance..




Wheel off.. wheel on .. wheel off.. wheel on.. and so on...
And poof... we have a number...




Mind you.. this was my first time corner balancing a car..
All around spring height deviation is no more than 3mm.
Front/Rear balance is not perfect.. but will have to do..




Any of you corner balance experts in here?
How does that look?
Would you go for cross weight more or for left<->right weight distribution. (trying to match the front left and right side weights)

What I am saying is that I could have had 51% cross weight and difference between my fronts would have been 25lb vs 50.

As the temps drop to a comfy 88F in the garage...
I can start working again..




Anti-seize the world !!! I use it as a rust protector as well. Marine grade does not wash off that easy.



Spacer or no spacer.. Once the car was lowered, it ended up not needing one.



Up next was the front.



Seems that the bolts supplied are too short. Engagement seems to be the thicknes of the bolt but I think they will need to be replaced.



Forgot if there needed to be some tension on the links...
I do have some butits marginal.

Since I had some more wire laying around it was time to start twisting again.
This time with some help of "iced lemonade".




Looky here a very pretty diagram.



What seemed so complicated is so easy.. The PDM needs only 3 connections.
Slow, Fast and park. It senses where park switch goes to ground and stops the motor.




Tough jobs call for some creative thinking.



There you have it.. punched through behind the motor for a clean look.



Just need to figure out which lead "parks" to ground.



Since I dont have any wiper arms had to use some tape.
Once parking was configured it worked but the wipers parked in the vertical position. I had to flip the motor arm around in order to fix that.




Last but not least the keypad earns another sticker !!!



Played with intermittent settings but couldnt get it to work yet.

Them trannies leak sometimes I guess.
With new Motul passanger's axle just started to piss instead.




Sucks not having the right tool.
Hope its close enough..




Last but not least.. Here is a fun fact from local Subie dealer.

Very cool work
Be careful with that sun-dial, you'll want to have that set correctly of course. You can quickly muck up your front diff gears...

Made a trip to a local U-pull since they showed they have a 2000 RS...
It ended up being a wagon.


Anyhow.. there was a 1993 Impreza as well..
Managed to swipe those beauties.




Having issues with fuel gauge displaying low fuel I managed to find a 05 Fozzy...
Pulled the floats out of it just in case mine were bad.




It was a bitch to pull it out but I got tired of not knowing how much fuel I have.
Tested the resistance and it fell withing specs..
For those interested this is how they read:

Left float:
Full 2.2 ohm
Empty 44 ohm

Right float:
Full 0.5 ohm
Empty 50 ohm

Both Fozzy and Sti floats read the same.




Pulling the passenger float is always a bitch...



I was about to switch them for ****s-and-giggles and noticed that the arm arrangement is different.
Since the pass fload read lower than the drivers with 1/2 tank I've bent the float arm a bit.. Figured with it laying in the garage for 3 years it might have gotten bent.




What do you know.. It magically started working.
Somehow I feel it was binding somewhere and after removing it and putting back it re-aligned.
Had a 5 gal jug and filled it up, while watching the gauge....

Here we see a great example of 26 year old wiper arm.
For all its age and how its been beaten by the weather its still not bad.




Here we see such specimen taking a bath in Phosphoric acid mixture.
I think total of 2hrs was required.




Primed and 3 coats of paint... 15 min interval between coats and the **** still runs.



Next on list was a feature I wanted to add for a long time. I've read in few posts that said it's not possible and few other complained as well.
So after a short test.. 2 additional leads were created.




After fiddling around with scaling, the ECU now sees oil and fuel pressure off the Defi gauges.
Super stoked about this!!!
Now I can log both and include those in the "Engine Protection" features of the ECU.
Basically limit rpm or kill engine if oil pressure drops below X amount.
And drop boost if fuel pressure varies within X during boost.




For those that dont know about scaling..
in a nutshell...
you tell the ECU the voltage at 0 psi and the voltage at a 2nd known reference point.. 52PSI for fuel in this case.
since most sensors are linerar ..
based on that you interpolate the values in between and extrapolate beyond your 2nd reference point.
So with in tank pump on I get .3 bar on my gauge which is 8.7psi (@0.8V) and 52psi at 2V when is my 044 is on.
At boost there will be more than 52psi so the rest is extrapolated up to 100psi.

Ok..
did few runs with the oil and fuel pressure sensors hooked up and the output seems credible.


Spent some time fiddling around with "General Purpose RPM Limits".

GP 1 - is Oil pressure table
GP 2 - is Fuel pressure table

Basically what happens is Link will cut spark if a condition is met.

Lets take GP 1 - 65psi / 2000 rpm cell. (rpm limit is set to 2000)
My minimum oil pressure at 2000rpm is 65psi.
My normal pressure at 2000rpm is 75+psi.
So in case that I hit 2000rpm and pressure is still 65psi it will start to limit the rpm to 2000rpm.

The trick with the limit is that it kicks in 200 rpm early.. at 1800 rpm.
By 2000 rpm its a full spark cut.
Between those 200 rpm the cut is progressive so its much smoother on the engine.
2nd variable is "Activation Delay". The cut will start in my case 2 sec after it hit but only if its still in that cell.

At 65/1500 its allowed to go to 4000, but if the oil pressure does not increase by 2000 rpm its only allowed to go to 2000.



With fuel pressure its similar case but thats referenced on MGP pressure instead of rpm.
If there is no rise in pressure for given boost prressure the cut will occur.

Finally came time to close the rear parcel shelf hole.
Here we start with some CAD equipment.




Biggest challenge is getting to the back witout removing the seats.



Meet the sheet.



CAD template was transfered but I decided to do the arch with some string and a marker since my trace of the window wasnt perfect.



Installed pics coming tomorrow...

Last but not least for today...
I had to strip and paint the wipers again.
Finally a set of wipers installed !!!

So.. I've been playing around with knock sensor.. trying to get it "tuned"...

Since I cant hear it.. it was time to check them plugs...



Yeah.. I'll rub it in...

It took me about 10 minutes..

If I really rushed, half that time.






Plug #2



Plug #4



Plug #1



Plug #3



Post your opinions...

Decided to visit a local junk yard since there was a 07 impreza in the lot..
Scored glove box, air bag cover and license plate ligts




O yeah.. scored those two as well..
Some poor sucker left his tools.




Finally I could install the cig lighter and a usb charger.



Both light up..



As an added bonus I gained a passenger's foot well light.



... and that Nissan license plate light replaced the original Subaru one.

So.. after running the car to literally zero fuel the gauge was still showing a bit above 1/2 tank.


Since removing the floats is a pita... I was hoping that my last time solved the issue.

Little did I know that the float was binding on the jet pump assembly.



After putting some tension on the hoses and twisting the jet pump it was time to whip out the safety wire pliers and secure the jet pump as it was wiggling...
Those pliers dont see much use.. but create very nice results...




Here they are... resting after "once every 2 years" usage...



Frustrated enough.. it was time to put this problem to rest.
Since there was no gas in the tank.. I decided to do a empty-full-empty-full test.
20gal even was supplied.




After filling it up with 10 gallons the gauge showed a bit more than 1/4.



I've decided to fill it up to the max and to my surprise I coud fit about 12-13 gallons..
Emptied the tank again.
I run the fuel pump and pumped all the gas back into the cans.
Then I put some gas back in and decided to test the jet-pump.


I run the pump but... the jet-pump was pumping the fuel into the other side instead of sucking it out !!!


This is how the driver's side of the tank looks when the passanger's is empty.



Lesson of the day !!!
Dont be like this guy ^ drilling your jet-pump thinking it will make the fuel flow better.




New jet-pump is on order.
