So you about got that Motec about figured out. I been thinking about them a lot if i start making Exotrucks. I'd like to set it up so the body wiring is seperate from the engine wiring so that I can have a variety of power plants.

Thats basically what mine is.. "modular" I call it.

The PDM still ties into the engine.
But you can make "universal" with given set of outputs.

I was looking again though, the price tag on those is a killer. Started looking at regular fuse blocks again lol. Wifes got me making another one soon. A pink automatic!

It seems expensive.. (well.. it still is more expensive any way you look at it)
If you add all the components separately...
15x20A circuit breakers = $300 (klixton)
15x20A relays = $75
connectors = $50

Thats almost $500 right there.
Wiring up all those will add time.

But yes.. you'd need a keypad. (additional $500)

On a bright side.. you have CAN communication with your dash display.
If you going to provide a "universal" engine solution then you need a dash display.
Unless the owner installs his own engine and engine harness, cluster and misc switches like wipers.
Lots of things tie into the cluster.

If not then you'd need a standalone ECU.
This now limits your market to off-road vehicle in many states.
OBD laws ?

I'd think your production would need to be on pre-order basis.


Unless of course if you sell it as a turn-key solution.
Tuned and ready to go..

Then comes a reliability issue. You'd need to stand behind your product.
And them ex-Honda and now vaping Subaru owners are just standing by and ready to throw you under the bus any way they can.

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 and lets see..

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.


:rolleyes:

New jet-pump is on order.

Not entirely relevant but I've found that Seafoam does wonders for wonky fuel floats. The car I just put back on the road wouldn't read any changes in fuel level above where it was when it was parked. After a few days of Seafoam in the gas the gauge works a treat.

And... 9 days later this guy finally arrived.
Extended wait courtesy of the local Subaru dealer.




Installed and looking good. (or is it?)



And here we go again... 10 gallons in !!!
Out it comes again. :censored:




It was still binding somewhere but I cant see where...
Started looking at pictures and the siphon tube was bent past the float.
It should have been "below" the float as it is now.




Empty, refil, Danielo son..
Once the passenger fuel bay was empty I bridged the return hose to test the new jet-pump.
Works like a charm sucking fuel into the passenger's bay.
This went on back and forth few times as I couldnt tell if all the fuel was pumped out of driver's bay.




Final re-fuel..

0



5


10


15



So.. now you have your gallons to gauge reference.
You're welcome.

I am sure all of you are so anxious to find out "whats in the box".


So here it is..
KnockBlock
A little device that lets you hear and record the actual knock sound.

But you have a knock sensor you might say..
Yes.. I do.
Then y the expense you ask?
Well I cant tell if what the knock sensor "sees" is actual knock, thus I need to make sure that knock is knock and based on that tune the stock knock sensor.




The unit comes with 2 additional knock sensors.
And with the stock sensor already mounted there arent many options for mounting.

Meet the M10 bolt.
The small problem is the knock sensor takes M8 bolt.




Now meet my "lathe". Not to be confused with latte.



Aaaand ... Done.



Assembled and ready to be mounted.



But wait.. there is more..
Why stop with one bolt ????




A little "lathe" work and a little tap tap later.



Why the nut you ask ???
Well.. this is the Power steering/alternator bracket.. and the torque for that bolt is around 30ft_lb, plus I dont want any tension on the sensor either.
So the stud with the nut is tightened to 30ft.lb and the knock sensor to 20ft_lb.




And here they are ... mounted. (Left one)



And the right one.
Hopefully the location is not that noisy.

So.. Did my first run with induced knock.
Added about 15deg to timing.


This is apparently what knock looks like.




Frequency range seems to match the calculated frequency.
Since the knock sensor uses 2nd harmonics this is the formual if you ever wanted to double check.
2nd Harmonics Knock (kHz) = 3600 / (3.14 * piston diameter in mm)

Ex: 99.5mm bore.

3600 / (3.14 * 99.5) = 11.5 kHz

Altought I've seen Subaru knock settings at 13 kHz.
Which is weird.



Correlated the audio with my log and looks like my knock sensor settings are working properly. ECU took out 6deg of timing at both occurences.

Just spent the past few days reading this build thread during down time at work. My mind is blown! Your ingenuity, attention to detail, and dedication to this car are mind-boggling! I definitely have a question, if you feel like sharing. I can't imagine what the sheer cost of a build this detailed amounts to. Is this something that was funded personally and purely out of love for the car or was this funded through a sponsor of some sort? If this is all you, aided by colleagues and friends donating skills in construction, it adds an entirely new level of respect for the build. Anyway...I've thoroughly enjoyed this thread. Thanks.

No sponsors here. Fully paid for by myself.
I've bounced the idea around few vendors but got blown off and nobody gave 2 :poop:.

The project is a colaboration between 97WRXwagon and me.
After all, he sparked the idea and had the knowledge to build it.
And for that he spent hundreds of hours in the garage.If not thousand + ??? :D
Must say.... I've learned quite a bit from him.


Glad you liked the build.
I tried to make it somewhat entertaining.

GUI seems to be very intuitive. Log display is thing of beauty compared to some that I've seen.

Feature wise.. Everything seems to be there.
I just havent gotten to many things yet.

Online support is good too.

Only downside I see is that I cant seem to be able to save the knock audio right off the Link software.
So synchronizling the knock audio off a 3rd party app and link logs might be a pain if you doing more than 1 pull.
Just more tedious.



How are you liking the Link so far?
