Default Advancing the Timing and Dyno Tuning

I was wondering what are the ways to advance the timing. I know you can use a timing gun. Can someone explain who or how that is done. I had a 00 SI on which I advanced the timing by moving the distributor by about 6mm. Is that possible to do with the Type R as well? Does advancing the timing actually distribute equal power throughout the band? Lastly, I would like have my car dynoed but I am not sure how to go about doing it. Where can I find a local dyno and how much do the generally cost. Thanks!

It's the same on an ITR. But 6mm is too much!! It's more like 2-3 mm.
Advancing the timing will increase the power through the whole band. But you'll need good quality gas.

mine is set at 18 degrees BTDC (all the way) and been like that since last Dyno about a year ago. with good quality gas there is no problem and it gave me 2 max whp and + - 5/8 wtq at low rpm.

I would get a timing light before doing it. Blindly moving the distributor can get you in trouble. I don't understand why people are willing to spend $500 for an exhaust to get 5whp but then are unwilling to spend $30 on a timing light to advance their timing correctly for the same gains.

We have an article at Team Integra on how to do it.

What octane gas do you mean by good quality? I use 93 now. Would that work or would I need 94. Also, I am planning on putting a JUN ECU in my car very shortly. Will that effect anything such as...will that give me less or more whp? Would it still be safe to do with it? Thanks!

Those off the shelf ECU's sometimes don't work well when you have done specific mods. I remember someone with the Comptech ECU lost power after advancing their timing. There's just a no way an off the shelf ECU can tell how your specific engine breathes so if you do more to your engine than what the ECU was designed for you'll probably get losses somewhere along the line.

Can someone also explain to me step by step instructions on how to perform this task with a timing light. Lastly, can anyone tell me how you go about dyno tuning your car and how much it costs? Right now I have an AEM intake. I am putting a JUN ECU with a OBD1 conversion in very soon. I am then gonna advance the timing (would it still be safe/worth it to do it with an OBD1 and a JUN ECU). I plan on getting a Tanabe Racing Medallion within a few months. How much whp do you think I would get from all that combined once it is dynoed? Thanks!

Well, I have spoken to the guy who is selling this JUN ECU. He said he got a very good amount of whp. He also has the AEM intake, some headers and cams. He said with just inake and exhaust, I will still get around 7 whp but the best part about the ECU is that the redline is moved to 9600. He said that when you are racing your car, by the time you shift into the next gear, you will always be above 7000 rpms. What do you think?
