vagon2014?

 

You are correct. Assumption only. AFAIK, there is no PID to read if/when the knock sensor picks up detonation. There might be some way the HDS can read knock sensor activity, but I don't know.

As far as other comments re: impact of temperature... I'm guessing yes, temp does play a large roll. I'm not seeing any retard at all with 87 (up to 70% load) during highway driving, but it's very cold up here right now. I'll be interested to see if that changes as the weather gets warmer.

I'm also curious as to how I get ~34.0 timing at 45% load (highway cruising at 74 mph), but 6sp-GERCO (with an identical car) only got 29.5 with slightly less load (70 mph). [post #210]. I've seen no change in timing for temps from -10F to 40F (again, highway driving), so I'm really confused why there is such a large difference between his numbers and mine....

I'm still waiting for good roads and enough time to run back to back tests of 91 vs 87 on the same day. Here's what I have in mind:


3 hard pulls in 3rd gear from ~20 mph to 6K rpm
3 runs pulling through each gear with a shift point of 4K rpm up to 75 mph

 

I look forward to seeing that too!

 

How long is this going to continue?

 

Hopefully forever!

Run your own tests....

 

I'm sorry. I haven't saved enough money at the pump to afford that. You could buy it and ship it to me as a gift.

 

I ain't putting 87 in as a test

 

The engineering staff here in this thread concluded that 87 will NOT cause any harm or damage to your engine because the knock sensor will become retarded. Further more, it was also concluded that everything pertaining to use 91+ is all a MYTH, made up story like 50 shades of assholine. Now if you aren't willing to run these tests and post up MS paint graphs, you should kindly remove yourself from this delirium thread.

Don't be a vagina..

The old girl probably likes drinking the cheap stuff nowadays.

 

Dang that's cheap..

 

Maybe if you filled up with 87 you could afford it.

 

What if I can't afford 87?

 

Then you can't drive! And now with gas prices heading back up ...............

wow, this thread proves that most acura owners are more emotional than a 15 year old emo girl living in downtown LA. rusty is coming from a analytical point and giving information and people are seriously getting pissed off. book says recommendation not requirement. grow up, if people want to put 87 thats fine, doesnt affect any of you all crying and moaning.

take the time to research and get your own information that can prove different other than talking your garbage "you're going to damage your engine" "ferraris owners don't put 87" "arguing for the dollar, they will never own a ferrari"

people here drive an acura, acura themselves are a cheap company. thats why they dont compete with lexus, mercedes, or bmw. they are "smart luxury" acura compares themselves to them but actually competes with volvo, honda, kia, hyundai and the deceased saab that's in your neighborhood junkyard. acura (a nicer honda) is a company concerned about saving the dollar. sales and information coming from acura themselves in the past decade proves that.

 

Thanks for your valid input.

You've been a great contributing members from your starting date on Acurazine in 2012.

 

Ok buddy. Whatever helps you sleep at night.

 

Onepumpchump_sam can't hear what you're saying over the sound of his engine knocking on 87

 

He also used some great choice of words which CLEARLY goes against OP's rules in this thread. This now concludes that Onepumpchump_sam may get Ban

 

8 posts in 3 years.. I wouldn't wait for a response. He'd get banned and wouldn't even know it.

 

Wait.. Wait.. Woah.. Onepumpsquirt, you can't compare an Acura to a Kia or a Hyundai. Lexus does have a good track record for reliability, but overall, imo, the cars themselves don't look or ride any better than Acuras.

 

Exactly. This is what I've been saying. Rusty says he has data which includes RPM. I offer to plot his data so that the ignition advance is shown as a function of engine load and engine RPM. Ask Rusty for data file. Rusty tells me to sod off. Tells everyone to post data or GTFO but won't post his own data. What a hypocrisy circus.

I actually have torque and an ELM327. I'm going to collect my own data on 93 octane and post it here.

Rusty, you might want to read this too. Your graph clearly proves that there are other inputs which determine ignition timing.

Lol, Vlad, your boys nfn and rustytrombone are both long gone. All that's left is the occasional tumble weed blowing through

 

ur dumb.

 

and newsflash.

all companies are concerned with "saving a dollar". It's called a profit.

 

If companies are saving dollar that is
But when it comes to an individual saving a dollar that is

 

Haha I think rockstar was just pointing out that all automotive companies will save money where it makes sense, not just Acura.

And I'm pretty sure nobody here is opposed to saving money where it makes sense either. We just seem to disagree on the where it makes sense part of it lol.

 

We still haven't proven that 87 saves money for all cases. In previous threads, I mentioned that if extra unburnt fuel is being thrown down the pipe, you might be damaging / clogging your primaries as well. Those aren't cheap to replace unless you intend on coring them out.

 

Acura is big into going cheap. At least other mfgs go cheap, their cheapness is durable.. at least the interior trim items.

 

Get outta here Frosty....

 

i am glad you are able to decipher numbers and read when i joined, shows that you are able to read. you want more opinions? grow up. i dont care if i get banned from this childish site. i came on looking for mature people.

thank you for your contribution of making people who drive acuras look like douche bags. i did not realized i joined an immature racer fanboy page. on the side note i will be warming up big ass bottles for all the big ass babies. i still have to go buy some maxipad ultraflows for those who need it.

on the side note, rusty's information that has been gathered is very valid, i do run premium but i work in the oil and gas industry and ive been told do the elevations, you can get away with 87 octane versus 91. but to each their own. let people put what they want, its their car. knowledge is golden and lets try to act as adults. if people want to act like children then they get treated like children.

ill put it in a language these non analytical childeren that just talk crap can understand rusty

this is data gathered about gas, if people have data about engines being damaged then please show your information rather than just saying "it could be more costly"

could this could that, prove your point rather than baseless comments, there is possibility casing damage using poor fuel, not changing your fuel filter, cleaning injectors, regular maintenance. but if acura is saying recommends and not require, thats all it is. acura will say if it requires something. my manual says recommends. if it is a type s i would imagine it says requires.

 

 

With all you ranting and raving, guess you don't read the posts as your manual has a heading Fuel Recommendation which is 91 and to add, the Type S is the same.
Actually the following use the heading Fuel Recommendation, so I guess in your mind, that means 87 is/can be used without a problem:
2012 Porsche Panamera
2013 Porsche 911
2015 Corvette ZR-1
2012 Cadillac CTS-V
2015 BMW M5
2013 Nissan GTR

I sound like a broken record, but trying again.

Also, to add, you can post all data available and will the data ever show engine damage or future concerns? No, it naturally will indicate timing adjustments as we all know, but will the use of 87 do any harm, I say no as long as the driver doesn't think and use his/her car as if they were on a drag strip. Also stated before, I know many that use 87 in vehicles designed for 91 and no long term problems, nor any mpg changes, at least measurable.

 

So I've been running 91 in this last tank, waiting for good roads/weather to run more tests. Interestingly enough, I've found that as ambient temperature drops, so does timing advance (at least in cold weather, in certain ranges).

For an ambient temperature of 25-30F, timing advance was ~34.5 (the same as it was for 87) for ~45% load (~2600 rpm). When the temperature dropped to 0F and then again to -20F, timing advance dropped to ~32.5.

It's interesting to note that a ~25 degree drop from ~25F to ~0F resulting in a timing decline, while a ~20 degree drop from 0F to -20F did not.

I'm still waiting for warmer temps and better roads to run the full 91/87 comparison. Might be a couple of weeks before that happens...

 

good info...
