@satibel The pump sprocket should have a hard "index" or some sort of indicator for timing. A notch, small drill mark, or other hard reference that cannot be "smudged". Make certain the sprocket is super clean and inspect for some sort of witness mark. A repair manual for that vehicle may give an indication of exactly where this mark is located. I would advise against guessing, as the injection timing may be well in advance of TDC.

(But exactly how much is not a good guessing game to play.) My buddy with a similar BMW 2002tii race car decided advancing the injection timing one notch on the Kugelfisher (petrol einspritze) belt would give him an edge. And it did. Until the rather violent "BOOM"... I'm happy he did the experiement, not me.

@Pᴀᴜʟsᴛᴇʀ2 what's cooking?

@Zaid - Nothing much.

You?

Waiting for a meeting

That's always a plus ... (not)

I'm wrestling with R code today

Mucho fun

Your code? My code? R code?

;-)

You can have it all bro. I insist ;)

I don't believe I've ever looked at R code.

You working it for Unix, Linux, or Windows?

Windows

Great fun.

@Zaid - And yet they use a Fram oil filter ... argh ...

Never heard of it

I mean the brand

anyone have any familiarity with the turbo design in the 2018 Mazda CX-9? Just picked one up and it seems pretty responsive, but was wondering how truthful the salesman was about it

and the service manuals aren't up on alldatadiy yet, so don't have access to much technical data yet

@AJHenderson - What is it he told you and you have concern over?

not really any concerns, just wondering if it is really as innovative as he said. He mentioned something about the design focusing down the air in a different way to reduce the turbo lag

but he didn't describe it very well and the engineer part of my brain is curious about it

I know mazda in general takes a slightly different view to engine design, so it wouldn't surprise me, but the details were a little fuzzy

I have a pretty good idea of how their direct injection and compression ratio stuff works for the combustion side of skyactiv, but my understanding of turbo's is a bit more limited. I get the basic idea, but have never really worked with them so I don't completely get the difference between a typical turbo and what Mazda is doing with their new design

oh, that's interesting, apparently the 2.5T doesn't use the compression ratios for it's efficiency, though it is still direct injecting

automobilemag.com/news/…

here's a relevant article, guess they've been using the design since 2016, not sure if anything's changed in the 2017 or 2018, but it does appear to have the variable nozzle

@AJHenderson - I've read about Mazda's Skyactive engines, but I don't know enough about them to speak intelligently. I do believe they are going to perform at the level Mazda is talking about. Considering the engine has over 300 lb-ft of torque @2000 rpm is amazing. That should be a real seat of the pants thing going on there. You should be really happy with it, I'd bet. I'd assume the salesman really didn't explain it well, because, well, he's a salesman and not a mechanic :o)

He's excited and sold you a car, so he's done his job! haha!

@Pᴀᴜʟsᴛᴇʀ2 yeah, this particular sales man has worked in more technical jobs before though. He actually used to be a sales guy at where I work now

so he has atleast some understanding and Mazda apparently does do a basic technical training

@AJHenderson you can't have high compression ratio and a turbo together. At least not usually

@Zaid yeah, I saw that

@AJHenderson - I used to sell Mazda's back in the day. Then they were a pretty good vehicle and I have no reason to believe it otherwise now.

@Pᴀᴜʟsᴛᴇʀ2 really? I didnt know that

yeah, my Mazda3 used one of the naturally aspirated high compression ratio designs and was fantastic and this one adds even more torque and it seems to drive very well

Unfortunately I don't have the time right now to do a real "deep dive" on the Skyactive system to give you any real feedback on it.

it's my third Mazda in a row

Any issues with the EGR clogging up?

@Zaid - Yah, I sold them for a while while I was between contracting jobs (got laid off from one company and nobody was hiringm, so had to do something).

On the Mazda3, I mean

no, I had a 2012 Mazda3 for 6 years and it ran flawlessly the whole time other than a firmware issue with the voltage control on the alternator that was a simple software fix

but it was also only at 51k miles when I traded it in

had to get a bigger car for growing family

Maybe those will help?

possibly

Could you imagine this engine in a Miata? :o)

just the article itself that I found gave a pretty good idea too

Dude on EE explains things pretty well.

I couldn't believe that the CX-9 has .5 second better 0-60 than my Mazda3 did

had a 7.8 0-60 on the 3, but 7.3 on the CX-9. Gave up a bit on cornering, but .89 lateral Gs is still almost a full 10% better than the next closest competitor in segment at 8.1

err .81

it's about the closest thing to a road hugging 7 person SUV ever

and if it gets anywhere close to the 22-28mpg it is supposed to...

havn't gotten a good feeling for that yet though since it's been saying 7.8 to 12mpg due to spending a couple hours idling while I configured all the personalization settings

@AJHenderson I'd bet there's a way to reset the counter if you wanted to c:

@Ceshion oh yes, there is. I know exactly how to

there's actually two or three different options

I just haven't bothered

I made the life of the person that does the new owner training at the dealership really easy since I'd already read the user manual front to back twice before picking up the car

not to mention the quick start guide and had scanned the navigation system documentation

I actually ended up correcting them on one point and then just asked if they knew of any little shortcuts that I might have missed in skimming some of the sections, the only things they had I had already read, so it was quick

I will say one thing about the new car that was super disappointing though not something I cared about anyway was satellite radio. It came with a free 4 month sub and it's so laughably bad I don't know how they are still in business. Especially not with how much they charge. I get unlimited internet for my smartphone and FLAC streaming for less than double the price and that's assuming I did nothing else with my cellphone

@AJHenderson - At this point, I'd agree with you. It was a great feature when it first came out, but with cell coverage as good as it is now and how cheap data is getting, it really doesn't make sense. If you are in cities with tall buildings, you can't get Sirius/XM ... but you can still get cell coverage.

@Pᴀᴜʟsᴛᴇʀ2 yeah, I could possibly see that, but I can't believe they've kept the price so high

in 2001 it might have been worth it, though honestly, FM seems better most of the time. It beats AM most of the time though

@AJHenderson If there was only the choice between AM/FM or Sirius/XM, I'd take satelite every time. The reason is, it's available throughout the US (for the most part). If you are on the road a lot, you can listen to a single channel without worrying about finding the new channel when you leave a broadcast region. It becomes moot with cell coverage, though, as I can listen to my favorite channel anywhere using iHeart radio.

The other big draw from satellite is the availability of channels without commercials. Almost worth paying for that alone. But, then again, you can use online services without commercials and for free, so there you go.
