Info for the 1gr

As someone mentioned earlier, this text was pulled from the FSM (Factory Service Manual) for a Tundra apparently. Since I do all of my own service I have one for all three of my Toyota's. An FSM is a must have for anyone who owns a Toyota and plans on doing any of their own work. Even if you don't do your own work you will be more knowledgeable when you have to take it to the shop.

They cost about $125 and you can get them in hardcopy or online. I prefer the hardcopy because I'm old school and my laptop doesn't get dirty when I'm working. Don't waste your money on a Haynes or similar shop manual, suck it up and buy a manual from the people who built your vehicle.

Although FSM's are not cheap they will pay for themselves after you do one repair yourself.

 

all the information you'll need along with the original file the OP posted.

enjoy!

 

Awesome!

 

Wow, after reading it I'm having a wish to buy such car....it is really very comfortable for country racing

 

That's great I am glad you found this info! Pretty helpful!

 

Can anyone tell me how the knock sensor cycle works?

I've read that our trucks make more HP & torque on premium gas. So, let's say I fill up with 87 octane pee water, the knock sensors pick up some pinging, and retard the timing. What happens from there? How does the ECU know when to re-advance the timing?

When I fill up with 93, if no pinging is heard for a while, will it advance timing? How long does it take to do this?

 

Hmm...I guess no one knows

 

Hey; cool stuff, thanks!

 

Great! Now if I could only understand most of it! Looks High-Tek!!!

I was looking for the link on the first post, I thought there were more pages to read the 1GR-FE? But thanks for that anyway

 

There was, I’m looking for it.
I will see what I can find.

 

I think this is it?
I didn’t download the whole file.
But it looks correct

Many thanks for your research, but I'm not able to download it without credit card I don't want to register

 

I didn’t even try. I shall search again. Lol

 

Here is the Dual VVT.
The Tacoma doesn’t have Dual VVT.
That’s what I’m having trouble finding.

 

I believe the original one have deeper information but thanks for that I will read it tonight, good to know all the differences between dual and single VVTI

 

@bra
