That's old lol
Yeah cause he was actually positive about it, now its a joke.
Sounded like he was talking shit there too lol
I only read that small spot then lost interest, our fore-fathers were douches.
Me too. I've only read the red post like 4 times, I've never even read the rest lol
Dead wrong bro.
correct him then james....what is VVT-I?
Variable valve timing, with intelligence.
Intelligence means depending on the situation (cruising, idle, high load in mid and high rpms), cam timing will be adjusted to meet the driver's needs.
This is the algorithm for single (intake side) vvt-i:
Look at Range 4 and 5. These operation states are exactly what I stated above as performance oriented cam timing states.
In low to medium engine speed with heavy load, the system will advance the intake cam for increased VE. More VE = more air + more fuel = more power.
In high rpm and heavy load, the cam is retarded to again increase VE. The engine's internal dynamics are different at a higher frequency, so the objective is different at high rpm. More VE = more power, and more emissions.
I've got VVTI supposedly. Not sure how to tell when it does anything though.
It's working all the time. Compared to an non vvt-i n/a 2JZ, you have a much broader torque band and better emissions.
You could try disconnecting your VVTI OCV and run with your cam locked in place. You would likely throw a CEL though.
...and throw the car into another wall
But you're right James. It was a long time ago though you see. lol
I remember aspiring to get a post count like rollatuner up there.
Sorry for the resurrection-roast, I'm on my post-count thrust right now, I know you understand.
It was a gentle pwn.
Wait, James didn't get to 10,000 over the past weekend like I thought he would!
Oh yeah.... that's right.... the site went "down"
That's why fuck you gold is in affect again.
You missed me, and you know it.
Separate names with a comma.
