(Engine Trashed?) Thread of Unfortunate Events

I took tomorrow off so ill get those thrown in. I can display as many parameters needed. I do have an obd2 scanner that can freeze and delete codes. Just cant delete the permanent one.

 

This one has both front view and side view, short range focus bright enough led light and pretty decent definition...

 

Just got off the phone with procharger. The said they won't supply me with a factory tune because of the age. I have to go to a custom tuner.

What a joke.

 

damn

 

Here is some files for guys who can read them. The truck didn't drive worth a damn. Complete loss of power if getting the truck under load. looks like i chose b2s2 by accident on long fuel trim. meant to do b2s1.

 

Can you check if you are running in Closed Loop?
The data suggests a lean condition at 20% of accelerator and 2500 rpms

 

seems like the whole side of the engine is struggling with misfires. cyl 2,4,6.

 

sure thing, let me get the truck back up to temp and see if its in closed.

 

My EVAP pressure seems high? Don't know if it matters but throwing it in here for troubleshooting purposes cause there's a lot more smarter people in here than me lol.

 

Just a shot in the dark,
Have you pulled That sides valve cover to visually inspect cam systems?

 

I haven't yet. I haven't done too much since I got it back from the repair shop. They had the heads off. Hope they noticed if there was something wrong with the cam...but who knows lol.

 

Fix your vf logging for fuel trims. Add total fuel trim.
Add maf, coolant, injection mode, engine load. Knock FeedBack, cat temp
I would add vvt i change angles target and actual.
Look at lambda at 0 accelerator (fuel cut). You have 1.38, ltft is at +7%. Normal lambda is 1.23 and usually ltft is in negative.
Also see this segment
Ltft is rising with no affect on lambda. Lambda is rising and is in lean condition.
I would smoke the intake for leaks, etc.

 

I'll get a smoke tester heading my way. Thank you sir!

 

You low fuel pressure numbers are normal. Those high-pressure number are in kPa?
But here are normal values



Low is about ~400 regardless of rpms

 

High pressure is in kPa yes sir.

 

Based on pics in post 102, your high pressure #'s are the same i have in my logs.

 

How about: F#^ck any forced induction, install new stock engine and enjoy life?

 

Because a supercharged Tacoma is the most enjoyable thing ever. (When the motor runs correctly)

 

So I'm going to lean towards a vacuum leak of some sort for now. Won't know until I properly smoke the whole system. I know the truck ran amazing after fixing that hole in the tube. Then all of a sudden after 50min of driving. Went back to misfiring. Maybe blew a line or something somewhere else
