Hello everyone. I need to find out the ignition timing for my 07 double cab 4x4 1 GR-FE. I've got my tacoma in Japan, and I'm trying to get everything done so I can get a damn number plate for it. Your answers are appeciated.

Thanks

if no one has done any fiddle fartin around with your truck

the ignition was set at factory ....... needs NOT be touched EVER !!!

no less it changes by the seconds ALL the time
even while idling
or running in any gear
slow.....fast
does not matter

the ECU is constantly changing it

it is NOT a static timing
like back in dinosaur days

I just need the numbers/ degree's ( I guess). The place that is doing my emission test needs to know. For what reason I'm not sure. :confused:

Let me get this straight. You are in Atsugi, Japan and someplace there does not know that there is no timing that can be changed or adjusted on a Toyota??

Even though Toy-Taco can be hard to decipher, he is spot on. You have to have a distributor (something the Tacoma's haven't got) to adjust the timing. Everything is controlled by the ECU.

If you are dealing with someone in the BX/NX garage it would explain the ignorance. If this is a shop off base, I find it really, really hard to believe that they do not know that engine.

qft!

The only thing that can be gained by looking at the engine would be TDC (top dead center) by the marks on the crank pulley. The whole ignitor and coil are all on a "stick" that fits over the spark plug. Ergo there is NO timing numbers to be learned or used. You could plug into the onboard diagnostic port and maybe learn what the "timing" is for each polling interval. But there is no way to advance or decrease the timing.

Sorry bud.

The paper that I'm filling out just has a place for numbers. There isn't a box to check for ECU. I guess I will write ECU in the spot. The shop is out in town, but I wish it was on base.....it'd probably be way easier. The emission test cost $1500....so I want to make sure all the paperwork is correct. Thanks for all your help.

yeah I know tell me about it. If I have someone do the paperwork/ leg work, it would cost me $4500 (which isn't going to happen). This is Japan where everything is mad expensive. Since I'm in the military I had the truck shipped here for free and I didn't have to pay import tax. 1500 is ok with me. It's pretty cool driving left hand drive Yota in Japan. There aren't a whole bunch here. There are some places here that are selling 07/08 Taco's for $45,000.

You know, rather than running the risk of screwing up your paperwork do two things first. If you had a sponser check with them, chances are good they had similiar issues. If not, check with the base security office. They are going to have a local or two on staff as translators, if nothing else, that should be able to explain the finer points to you.

You are not the first, and you won't be the last, person that has gone through this and someone on the base should have the answers to your questions. Especially if this is your first overseas tour, you should be asking lots of questions and no one is going to hold it against you for asking them. Even if it is not your first, every country is different.

I wish my sponsor had done this, I'd be done by now. Now that I have the answer to my question, the rest should be rather simple. Again I appreciate all the help/answers.

My question is how do you adjust the timing if it is off? Let me guess, a computer right????

You don't. The ignition timing is electronically controlled by the engine ECU via feedback from the knock sensors.

So, the timing should never be "Off".

If im not mistaken Tacoma's are still built in Japan and shipped over. If you live in Japan why not contact one of the manufacturers and get the orig.l specs from them?

Just got back from a 10 day stay in Japan. Wife's family is still there so we go every year for the past 18 years. It always strikes me as weird that I have yet to see an 05+ Taco on the road. Forget about ever seeing a new Tundra. Dam roads are so narrow in the city that you could never get around, that is if you were rich enough to afford the petro and road taxes! Great country to visit but expensive as hell.

A few Japanese guys I know have new Taco's and an 06 Tundra. Yes the roads are incredibly tight. Gas on base is way cheaper than out in town so that helps a lot. :)
