This made me buy one of the last 2 NB timing wheels!
We'll make more! :)
For NB it can be FREE too! Just use a file and make the holes adjustable
these are so good! Thank you thank you thank you for this content! Love you guys
excellent explanation
excellent, excellent video
I've always run my NB on 98 RON (93 AKI). Regardless of running any mods. Australia's fuel quality is pretty poor compared to the US, and I only kinda trust the 98 octane.
Mazda actually recommends 95 RON as a minimum for the NB2 here. I don't know if thats because our cars make more power than the US' version, or if its due to the kinda poor fuel quality here.
Like for example the base NB2 made ~152hp, whilst we didnt get the Mazdaspeed, we got the SP/SE turbo NB, which made like 210hp.
Not sure why the differences in power though. I'd be interested in seeing what the differences are, but no one has really made a comparison side by side. If its just due to emission regulation differences, or something else like timing or compression.
Jeremy this is really interesting stuff. Not mentioned is that advancing the spark from 10 degree to 14 degrees before TDC increases combustion temperatures, and that increases production of nitrides of oxygen (NOX) in the exhaust. This can cause the engine to fail a smog test. One of the jobs of a catalytic converter is to remove NOX. An extra load of NOX shortens the life of the cat. CARB legal cats are about $1000 at the moment. So, in California the extra few horsepower from advanced timing comes at a price.
Just change the timing back when you get your inspection mate then advance it again
Everything on Flyin' Miata is always exceedingly helpful, and this vid was no exception. Learned a lot about timing the NB and I am thankful. However, I do have a question off topic of the video and about the car in the background... It's an NB, yes. It has the same spoiler on the trunk lid that mine (2001 Base) has but I have not been able to find any info about that particular spoiler. I see very few of those on the road. I was wondering if you could tell me about that design (versus the little smooth "humpy one" that I usually see), it's particulars, is it somehow special, or what? Or at least direct me to the source of all things Miata body parts. Thanks!
Is the timing advance on the 1.6 the same?
hey guys, just wanted to order one of those adjustable timing wheels mentioned at the very start for my 99 N/A NB1. Small issue: my two options for shipping are both over 120USD. I'm located in Australia. Surely it cannot be that expensive for a relatively small piece such as this. I paid less shipping getting my exhaust delivered internationally. thanks
Our shipping costs are usually automatically calculated using the current shipping rates we have in our system. If you think something is incorrect, please drop us an email at support@flyinmaita.com so that one of our Customer Support Reps can research the matter. Thanks!
You can make your own by filing the holes into slots, just do your research.
With the engine off the the driver right mark should be on the T? When using strobe 10* one mark on the 10 and other on the T?
Sorry but I'll need more info to answer this correctly. It's probably best to head over to Miata.net which has an article on base timing miata.net/garage/ignition.html or our instructions for the adjustable timing wheel here flyinmiata.com/support/instructions/ecu/adjustable%20timing%20wheel.pdf. Thanks for watching!
Hi, just curious if (na6) has timing set at 14 and 1.8 injector upgrade, what is you opinion with this setup. 91 octane.
The 1.8 injectors will not provide any extra power unless you are running a turbo. 14 degrees and 91 octane are a good match.
Does the 14 degree timing modification help on a 1.8 engine too?
Yes. It's complicated though. Go read about it.
I can't tell if my car is pinging. Any tips on detecting it?
You'll hear it. Sounds like someone is shaking a spray paint can.
To echo Key, if you can't tell then it's likely not happening. If it is happening, it will sound like a small diesel tractor (think Kubota) under load going up hill when the engine starts to lug. So on a long hill where you would normally shift down from 5th to 4th gear to maintain speed you will hear it as the motor starts to lug in 5th just before you would downshift.
Knock sensors can pick up knock before you can hear it. If you hear it, it's significant.
Shaking a spray paint can is a good analogy. Also marbles in a can, or popcorn, are ways to describe it.
Any idea why a MP62 positive displacement supercharged 1.8 would have no torque down low and build linearly like a rotrex?
It’s either way outside its efficiency range or there’s a leak. Look at the boost curve.
These things are correct, and to add, another possibility is if the fuel or timing are way off. With a supercharger, if the fuel & timing is anywhere in the safe ballpark they are less sensitive & will make what they make.
@@FlyinMiataVideo It makes 7psi at 4k and peaks at just over 12psi at the limiter.
@@TIGHTENmetal Fuel is definitely richer than i'd like. 12.5 mid range and rolls to low 11's on top end. Timing is retarded about 6 degrees but that's linear, so 6 at redline.
@@ricepony33 I'd definitely be looking for some sort of leak. At higher engine/blower speeds, it's able to overcome it. A loose clamp on a post-blower pipe, for example.
All is great, but could SOMEONE at FM answer ANY of my numerous emails? I am a return customer, yet I am treated like I do not exist...
We're truly sorry for any delays in email replies. Every customer is important and we are working hard to reply to every e-mail we get.

they're probably just really busy and short handed. They are good people. May not be Starbucks, but probably better
Patrick Ukemi Wrote third emails yesterday. To ALL the emails listed on their website. No reply. I really needed a brake kit for an event I am taking a part of in a few days. I guess it ain't happening. 😦

PLEASE ANSWER: I have coilovers that don’t have much ride height adjustability in the rear on my NB Miata. What’s the best solution for filling in the negative preload I receive from maxing out the ride height? Because it only goes as low as I want when I have about a -1.5inches of preload. And the car has been sitting unevenly from me taking the wheels on and off and readjusting ride height but I just can’t get it even without going back to the stock ride height. Should I buy new coilovers? Tender/helper springs? I’m tearing up the internet looking for answers but no luck please help!
"Negative preload" is a new one!
If you're looking for something to keep pressure on the unloaded springs so they stay in place, you need helper springs. You could also potentially use longer primary springs.
As for sitting unevenly, the best way to get in the ballpark is to set the perches in the same place on each side. Keep in mind that the car won't sit properly on the suspension until you roll it. See our cornerweighting video for some more details.
Flyin' Miata That’d be perfect except I can’t find any NB helper springs anywhere. I see flyin Miata sells them for the NA. Shouldn’t the NA helpers fit fine, especially since most coilovers that fit an NA are also compatible with the NB ?
@@AramysFS7 There's not really any difference. We sell some that fit any platform, although usually as part of a kit.

You've confused yourself
Kind of pisses me off that you're just totally blowing off 1.6 you're like and then 16 whatever. Not whatever I would like to know the information for the 1.6 computer that would why are you ignoring it
Dudes doing a good job, he doesn’t have to do anything for you lol
It’s an amazing amount of support for a 30 year old engine
I don’t recommend the timing advance especially on higher mileage cars. Would be interested in getting actual dyno charts that show an increase in power.
There have been dyno runs showing a power gain with 4 degrees of timing advance on Miatas for the past 30 years. It's pretty well documented.
would this be beneficial for an nb2?
Most of it is, yes. The NB behind him is an NB2, actually.
@@FlyinMiataVideo ahh ok, Im thinking of running 14 degrees with a stock ecu on my nb2, will it cause pinging? we only have 91 octane in California
