I run mine at 12degrees... 87octane and no pinging. Don't no why. I probably could go higher, but power is fine as it is.

Also, I have the same experience as you... 5degrees is much lower power. Unacceptable. Starting around 8, acceptable. And, 12 best.

Others have reported pinging as you do, at a higher setting. And a lot have the same experience as I have. I've no idea why. Maybe carbon buildup, gas, timing belt... but they are barely educated guesses.

 

1 mark? My 3VZ-E's looks exactly the same as the 3VZ-FE's shown here.

What engine are you talking about? 22RE, right? Looks like it goes higher than 12*.

 

The 1 mark? I am confused now, I thought that there was only 1850 marks.

Can you tell me what *'s the timing is at if it is in between the 8 5 mark?

sorry wrong pic

 

Oh...I dunno. Pick a number between 5 & 8. How 'bout 6*, or maybe 7*.

I'll guess around 14* BTDC is where the red arrow is pointing at there. It's marked at 12*, 8*, 5* and 0* BTDC. The last * mark(furthest left/indicated by the red arrow)has no number designating what * it is, but it would have to be more than 12* numerically.


Does that answer your question?

 

6 or 7.
it really doesn't matter what your timing REALLY is. 5 is stock, and you push till you like the power and don't ping, unless you like tossing money for higher octane. hell, your eyes and your timing light aren't that frickin accurate anyway. i'm just under 8, so i'd guess 7, but it doesn't matter. i'm going to keep pushing till i like the power, without the ping.

 

So is this on the v6's only, or does this apply to the 22r's? When I bought my toyota used, it was BTDC and not on the mark. The truck started hard and shut off hard. I set it to 5 BTDC with te1 and e1 shorted and the truck warmed up, and it stopped the hard starting and hard shutdowns. Now the engine is rebuilt and it is set on 5 BTDC. Should I try 10 BTDC or so. Will this make it run a little better. The truck is a 94 22r EFI. Bored 20 over.

 

i'm only talking the 22re, don't know about the v6--sorry, didn't mean to confuse the issue.
shouldn't think +20 would make that much difference, unless you've done head work or changed pistons.

 

Wow I’m so glad I read this thread.
I’ve been trying to figure out why my 95 3.slow running so bad on the highway. I have no power when I climb valley highways. Its seems there’s no power. I almost have the pedal to the floor and still not enough power and very poor fuel consumption. I always thought it was just the under powered 3vze motor. I’ve never checked my timing before and I think it time to tinker!
I’ll keep you guys posted to let you know my progression.

Thanks for all the info! I love YotaTech!

It could. You've got nothing to lose by trying, I would. As far advanced as possible is where your engine will run best. Just try to keep the pinging at a minimum. It may take a little experimentation to find the exact number you feel comfortable with.

 

The pistons are new and the head was redone. But kept cam stock. So I will give this a shot after I finish painting the damn thing. Keep ya posted! Thanx

 

I got the timing at about 8*. I really like the power! I guess it pings a little. I have lower than a quarter tank... But there is a really bad dead spot in the power band, down low, it just falls on it's face. I will try better gas, maybe 89

 

everyone who has advanced there timing at night after driving for awhile u should look to see if your exhaust manifolds are glowing red on yalls 3.0s because mine are and im kinda worried about it let me know if im not the only one

 

does anyone have glowing exhaust manifolds

 

Running at 12 on the 4Runner.. I could measure the temp using infra-red(next time I run), but definitely not glowing red.

 

No glowing manifolds on my 12 degree setting. I was thinking of going up to 14 but that glowing manifold remark will probably keep me from doing it.

 

Other reasons can cause that like a clogged cat or bad O2 sensor.

thanks to this post I bought a timing light at sears today (craftsman advance pro) for $69. A bit pricey but it's a really nice one and I hope to have it for life. After installing the Boyle's Alt Deathcougar and I boosted the timing to 16*btdc (my request, I wanted to see what it would be like!), and the pinging was pretty bad. So, today I bought my own light and lowered it to 14*. The power increase is excellent! I like it here very much. Unfortunately it is still pinging some, however mostly when I am just starting to accelerate. After giving some gas, the pinging stops.
I am wondering if some pinging is acceptable as a tradeoff for the power? In the Toyota (Chilton?) writeup from Mudhippy earlier, it says that some pinging is fine if it goes away under accel.
I am wondering if this is true, or if I should further drop the ignition timing down to 13* or 12*.
This has been a very enjoyable exercise and I am very glad for this thread, I would never have bought my timing light and spent this time working on the timing otherwise, thanks to all!

 

I had a Datsun 510 back in 1969 (still have it) which did/does just as you describe... right from the day I bought it. Never hurt it.

But I'd try backing off to 13 and 12 just to see if the pinging goes away and the power gain is adequate.

 

I just played around with my timing, and didn't find much difference by going to 15- 20 BTDC. I am at 10-12 now and it pings a little.
