Any of you guys gotten on a dyno at all? I'm pretty sure i'll make a few runs on one this weekend. Just curious as to other's results...

Sean, did you advance your timing yet. I think you told me you were planning on it the other day. Let me know what happened, becasue I would like to do it next.

When I asked my friend if he knew about an timing controller or if he would bump my timing to 14, he said there was no point because the computer would reset it anyway. Please give me some facts so I blow him away.

I told my Dad I wanted to advance the timing on my car and he said no. He said that it would damage the engine. My Dad knows a lot about cars and he said that I shouldn't be doing that to my car.

Eric,

Your dad is right, to a point.

I wouldn't let you advance the timing on my car either... ;-)

It is a simple task, but you need to be informed to do it properly.

First, get the service manual for the car (Engine only, about $100)

Then read the manual in the ignition section. It will tell you how to safely advance the timing to the maximum permissible.

Show this to your dad, I'm sure he will agree, and let you change the timing. You should notice a small improvement in engine response and power.

I would have to run the car at say 93 octane gas then right?

aerodyne

No.

91 is the requirement. If you stay within spec, you can run 91.

I would not recommend you adjust outside the allowable range, and neither would you dad, from the sound of it. It can be done, but it doesn't sound like it will happen.

You need to get a manual, or post this thread on the maintenance section.

from the maintenance forum. If you car is at 8, and you move it to 12, you WILL notice the difference.

Base Timing
Steps to check the base timing:

1. Connect the E1 and T1 terminals of either DLC1 or DLC2. DLC1 is the diagnostic socket located on top of the engine, and DLC2 is located by the driver's side left knee bolster.

2. Connect the timing light pickup to the No.6 ignition wire.

3. Start engine and aim the light at the graduation marks next to the crank pulley.

4. Factory base timing is 8 - 12 degrees BTDC.

The timing is controlled by the ECU, and as far as I know it is not adjustable. The ECU calculates optimum timing by using signals from the 2 cam position (g1 and g2 signals) sensors located in the left and right distrbutors and the engine speed sensor (ne signal). If you find that your base time is not in the factory range, double check your timing belt for proper tooth position.

I didn't understand a bit of that. I guess if I want it done, I will be taking it to a place that will do it for me. I doubt my LEXUS dealer will do it.. but there are some other places, and I would tell them to move it up to 12. Here, the gas we have is 87,89, and 93 octane. So I would be buying 93...

I have to differ my opinion the timing is adjustable their are 2 bolts holding the distributor loosen them the distributor moves the stock timing at least for my year is 10 degrees not 8. I dont know were you guys are getting your info but people have been increasing timing for years without any problems a computer chip is going to do the same thing what do you think they do they change the timing electronic insted of manually and then they want to charge hundreds of dollars for it.
