ESC then but EST was what I considered 2 generation
As usually your full of it. It passed every Echeck with flying colors
and passed by very wide margins too and would still today except the
stopped doing checks. In the 10 years they did it here I never had any
of my vehicles fail. The TDC baseline timing is so that aomw consumers
can feed their addiction burn "cheap" 87 octane in them even though
performance and MPG suffers. 87 octane was designed in 70's when 8 to
1 CR was the norm. When I got mine new in 89 I tried burning 87 in it
for first 8K to 10K miles or so and it was a real slug in hot weather.
After that I advanced timiing and started using 93 and never looked
back still runs great today and 93 and timing change added about 3 to
4 MPG to highway driving on long trips and better power too. I also
found during frequent trips to Colorado and Wyoming that manually
advancing timing to 12 or 14 BTDC helped performance a lot above 5000
feet during extended stays because "EST" cannot do it on its own. It
has been a while since I checked it but I beleive it is set at around
8 or 10 BTDC right now. People that ride in the old burb today are
surprized at how well it runs and looks even today. I make many
commuter trip thake my daughters to and from college on weekend during
school year and it is about 75 miles one way urban driving and when
gas prices are stable I make 3 trips up and back before I refuel and
it averages high 16's to mid 18's on these trip cycles. ( if you keep
it under 70 it will do around 18 mpg and at 70's and above MPG drops
a bits towards the lower number of the stated range.) Not bad for a
4x4 burb with 180K miles too and using A/C when needed because I never
drive it with windows down. BTW, except for a custom 3 inch single
exhaust with a quieter flow master and timing change it is stock too.
(no lift or big tires either)
Meaningless since IM emissions checks are orders of magnitude
different and more lenient than the original federally mandated
emissions regulations. You really don't want to debate this with
me considering that as an employee of the vendor contracted with
the state of Ohio, I traveled to Ohio many times in late 95 and
early 96 laying the groundwork for Ohio's emissions testing
It's still considered tampering. No different than removing the
catalytic convertor or an air pump or the EGR valve.
You wouldn't have gotten away with it in a state where the
ignition timing is actually verified to be correct.
Sorry, I'm not familiar with the phrase "aomw consumers."
Your 89 is a 5.7 liter, correct?
The stock compression ratio is/was 8.2 to 1
According to you then, 87 octane was designed for that engine.
I don't know if you've noticed, but in all these years that
you've been touting your kludge fix for your poochy Suburban,
I've never once said that advancing the timing wouldn't change
the way it runs. That still doesn't rule out that there is a
malfunction that you haven't been able to diagnose in 19 years...
That pretty much dovetails with the TSBs we got at the beginning
of each model year instructing on how to adjust 49 state vehicles
for high altitude operation.
No surprise that they are surprised, they were horrible trashy
Please explain why this makes you special such that you are able
to ignore federal law and tamper with emissions components.
If you can't do that, please explain what it has to do with
anything, anything at all...
The correct ignition timing is where the engine runs best
using the fuel that is in the tank. Actual timing numbers
given by the manufacturer happens to be a statistically
good number, but rarely the best number for all possible
If there were such a thing as "correct engine timing" as
an ordained value automotive engines would never deviate
from that ordained number as they do on the fly. Nor would
the state allow cars with a stretched timing chain to
stay on the road (for vehicles using conventional
But then again you do sound full of shit enough to be
a civil servant.
You're plainly an idiot. It is a rather ordinary mistyping
of the word "some". If you look at your keyboard you might
be able to see how that happens. But belonging to the civil
servant class of person doubtless prevents you from understanding
the ordinary things of life that aren't in your officially
No it wasn't. 87 octane was designed for general use,
not "for that engine." (See how easy it is to act like
a civil servant who behaves just like you do?)
The answer is in his better performance. Get a clue already.
And your point is?
So there is no single ordained number for ignition timing
The more I read the trashier you get.
Cite the federal law. They're all on the internet. I'm tired of
claims like this with no teeth in them.
Old Crow, help!!!! i have no idea if im typing this in the correct
place or if im answering were someone else is having a conversation
with you. please let me know if you even get this. please answer me
sorry if i have stepped on anyones mail or notes PETE
