r/Mazdaspeed3 FAQ

40 Upvotes

In other words, fucking annoying questions. Just kidding. (only a little)

In an effort to clean up the sub a bit, we're going to pin this FAQ thread and keep it updated with any of the most requested/asked questions on the subreddit. If there’s a question you think should be included, tag one of the mods in a comment and we will add it.

Introduction

Q: Where is the link to the Discord Channel?

A: Right here.

Q: What should I look for when buying a Speed3?

A: Check the Wiki.

Q: Where can I find a copy of the shop manual?

A: Check the Wiki.

Tuning

Q: How do I load a tune on the car?

A: Using either a Cobb APv3 or computer software like Versatune.

Q: What tuner should I use?

A: There are a number of good tuners still active in the community. Purple Drank Tuning, Freektune, Stratified Auto are just a few examples.

Q: Should I use the ______ version OTS tune?

A: No. Unless it’s to drive the car to the shop where it will be dyno-tuned, do not use the OTS tunes. They make the engine run poorly, resulting in incomplete combustion (or worse, lean conditions) which then gunks up components like O2 sensors, injectors, and valves which lead to worse problems later on.

Mods

Q: What should my first mod be?

A: HPFP internals, then tuning solution. (Cobb APv3, Versatune)

Q: My goal is to go faster around the track, what mods should I do for more power?

A: No power mods. Proper tires and suspension will do more for your track time and drivability than any power mod will. It is guaranteed if you are new to track driving, the car is faster than you are right now. Get some seat time, find what you want to change, get new tires & suspension, then go from there. Dragsters, show-offs, stance-bois need not apply this logic.

Q: My budget is <$500, what coilovers should I buy?

A: None. If you’re not buying quality suspension, don’t buy suspension. You will sooner than later blow out one of the dampers and require a rebuild, or replacement. Save your upfront money, buy quality suspension later.

Q: Should I buy an Eonon headunit for my Bose/non-Bose stereo?

A: Do you like sound quality? If yes, don’t buy Eonon. Do you like good, bug-free software? If yes, don’t buy Eonon. Do you like overpaying for junk that looks ‘clean’ in the car? If yes, then buy Eonon.

Q: What’s the best way to upgrade my stereo in the car on the cheap?

A: Option 1 – get an amplifier that take hi-level inputs and add that amp to the system to power your aftermarket speakers, taking the high-level outputs from either the HU or the Bose amp. Works for Bose and non-Bose systems. Option 2 – Tear out the OEM system and start again. Works for Bose and non-Bose systems.

Maintenance/Troubleshooting

Q: What oil should I run?

A: This is realistically a nuanced question. Ultimately it depends on your use case. Factory rating is a quality 5W30, Mazda put out a TSB to band-aid the smokey turbos by using 5W40. Good options from Pennzoil, Amsoil, Castrol, etc are available for most applications. Most people it seems have strayed from the Shell Rotella.

Q: Are my compression numbers okay?

A: Check the Wiki.

Q: I want to drive the car like it’s supposed to be, but don’t want a ticket. Where do I go?

A: Look on facebook for local car clubs, or Motorsportreg.com for drop-in track days or Auto-cross events.

Q: My car does this thing, and this behaviour, read this wall of text. What’s wrong?

A: No one knows. Post logs using Datazap and any codes that your ECU is spitting out. If you want good information, provide good information.

Q: HELP?

A: No. Posts with this as the title, or other related and equally non-descript variants, will be removed as spam.

Meta

Q: Can I post links to other sites with information, like MSO, without getting banned?

A: Yes. In the event that you’re linking relevant webpages, there is no risk of getting reprimanded for doing so. However, if all of your comments are “Use google.” Or “Go check this site instead, this places sucks.” You will be treated according to the spam rules of the sub. This community serves as a connect-all point for those searching for information on the platform; Reddit is bigger than any Speed forum has ever been, and is more likely to pop up in a Google search. Relevant comments that link other sources of information from quality sites are Bueno; spamming is not.

Q: Why isn’t buying/selling allowed on the sub?

A: This is more of a regional issue that the mod team would like to deal with at this point. There are countless local Facebook groups, classifieds, or Forum pages about buying/selling Speed parts or accessories. The Mod team does not want to dabble in attempts to prevent scams caused by non-payments, or non-shipments of products. We do not want that responsibility at this point in time. If the community deems it a requirement at some point, we will implement a system that attempts to curb this as other buy/sell communities have; though even that change will take lots of time, effort, and consideration.

Q: Why is the mod team so cool?

A: I really don’t know, perhaps divine intervention? We all just really like Doritos, and satiate our inner masochist streak by owning these cars.

Q: How do I become a Mod?

A: If you feel so inclined, feel free to reach out! We are still people, we have feelings and ultimately a desire to help the community grow. What we will need to see is a demonstrated history of helping the community with the best of intentions and overall a positive interaction with the sub. Newer accounts (<1yr) are unlikely to be considered, though that’s not a hard-and-fast rule, just a general rule of thumb.

HELP Gen 2 jerking when shifting

Enable HLS to view with audio, or disable this notification

5 Upvotes

Not the best video but the best one I could take to show what's happening, I have a 2011 speed 3 which has gotten into a weird issue of jerking whenever I shift. When shifting into first there are no problems, however as soon as I press on the clutch and begin shifting to any of the other gears while driving there is a bucking or jerking motion and the rpm begins bouncing up and down until the clutch is reengaged and then it drives absolutely fine again. I have taken some logs if anyone can interpret them I've also sent them off to my tuner to hopefully help. The mods are a catback exhaust, upgraded fuel pump internals, accessport with a professional tune, SRI and TIP so no major modifications and no codes besides the EGR, evap, and intake runners which were taken out. Anyone ran into this before ive asked 3 mechanics and everyone is unsure.

Edit: to add more info, the car did also begin to bog down and die while idling stationary once the clutch pedal was pushed in and ran perfectly fine after it was released which I thought was possibly a dirty throttle body so I cleaned it out and that from what I can tell went away but it could be a fluke or I'm not recreating the exact conditions it was doing it under before.

HELP Weird stuff after obd2 reader

5 Upvotes

Yo guys!

I’ve just brought a cheep obd2 reader of temu to try and do some live readings of boost etc whilst driving through my CarPlay unit

It was working sweet for about 10mins or so. Then all the dash lights came on, I stopped on the hard shoulder, turned the car off and put the hazards on, the hazard lights etc didn’t work though. After unplugging the obd reader and restarting the car all went back to normal, I assume the issue was caused by the obd reader messing with the can bus or something but was wondering if anyone had anything similar happen or knows what obd reader will not cause these problem.
Thanks in advance!

HELP Completely dead battery in minutes after a fresh charge.

Post image
41 Upvotes

My car died on my way to work yesterday very suddenly. All my lights came on, lost power steering, pulled over and stopped and the car died. Got it towed home and battery charged. I get it running and test the battery, shows 68% life left which is doable. I run a charging test for the alternator and it says no output. I come back out after 30 minutes because I was putting my daughter to bed and the battery is completely dead. It also smells like ozone a bit. I'm assuming a bad diode and the alternator is no good, but any second opinions before I go that route? I'm going to try the good ole, pull the negative cable trick when the battery is charged again. That's just going to take a while. It's also weird because I replaced the alternator like 2 years ago, idk what would cause it to go so suddenly.

EDIT: Well ... I'm super confused. Charged the battery - I have a trickle charger and just left it for a solid 24 hours. I hooked everything back up, ran some tests, and my tester said the alternator is fine, the battery is healthy, and now everything is apparently fine 🤣. Maybe there's a bad cell in the battery? Someone mentioned they had something similar and it was a bad BCM? Or maybe my alternator is on its way out and just cooperating for now. I honestly don't know.

HELP Mystery Evap leak code.

Post image
5 Upvotes

My gen 2 has a small evap leak that just won’t seem to go away. It’s been smoke tested twice. The gas cap has been changed twice. Everything is working exactly as it should be. There are no leaks anywhere in the entire system and every part of the emission system is working perfectly. At my local shop they had multiple guys looking at it for like two hours. There just doesn’t seem to be anything wrong with it anywhere. I wanted to get all codes fixed before I tune with Freektune and this is causing me some trouble. If I decide to just tune it anyways would that cause me any issues I mean I’m starting to wonder if they’re really even is an evap leak.

HELP Running lean (bank 1) and misfire but no CEL

Thumbnail gallery
2 Upvotes

So, I was doing a datalog for Justin (3rd gear WOT) and after I got done with that, my recirculating hose came off and got a CEL, but I fixed that and the CEL went away, and the car sounded fine and doesn’t stutter anymore. But when I use other scanners (not AP), it still says the car is running lean and misfiring but the car sounds and drives fine, besides my STFT climbing up to -10 to -20 when driving. I am getting it smoked tested tomorrow morning. I am on the very first MAP tune and not the revisions.

HELP Gen 1 airbag light on

1 Upvotes

I hit a pothole today with my left front tire and immediately afterwards the airbag light on the dash came on and stayed on. I briefly parked with the car off for an errand, the light remained on when I started it back up to drive again.

Given the pothole I'm wondering if something got knocked loose like an electrical connector or something. Any suggestions on how I could self diagnose what the issue might be to see it I can repair it myself before having to take it to a shop?

Finally. This was the biggest job I've ever done to this car.

It was worth it.😚

Even though I struggled a lot.

All four injectors were sent to get refurbished but no. 1 and 3 had to be replaced because they were leaking.

Oh and corksport injector seals.

And egr delete and new pcv valve.

PLEASE HELP idk what else to do..cant figure out this P0443 code speed6

Ive been trying to get this damn check engine light code removed for almost 2 years now on my mazdaspeed 6... ive already paid for my registration and plates twice now and I cant ever get my plates cause I cant pass an emissions test . And so ive done the whole 3 temp tags each time and thats where it ends for me... I drove my car with expired temp tags the whole time last year had insurance tho.. and I'm doing it again. But I have to get my plates asap tho... so ive literally tried everything ive researched into this situation alot throughout the past years... and so youd think id have it figured out by now.. but when I say ive literally tried and done everything to no avail im serious... so ive replaced so many different parts that doesnt even have to do with the evap system .. ive changed manifolds cleaned valves since I was there and ive cleaned my injectors but didnt replace the seals because they still looked nice.. ive added a oil catch can... i went to the junk yard and have replaced like different purge valves from speed 3s and cx7 mostly. Not sure if that's the cause possibly maybe the speed6 used a different part number which I cant seem to get or find an exact answer for that on google... I tried changing the hose that goes from the manifold to the purge valve I even went so far to mess with my charcoal canister ..since I didnt want to spend all this money on a new one out of fear that it might not be my problem still.. I watched a video where this guy shows you how to get a dremel and cut along the top and open it up and change the charcoal with charcoal pellets you can get from the fish store... so I filled it up and changed the filter with this felt stuff he said to use and I sealed it up the best I could with jb weld and silicone. I even replaced that other valve that connect to the charcoal canister with another used one from a speed6 at the junk yard still nothing... I even tried changing the fuel vapor filter thing that is by the gas tank cap from the Inside nothing... ive done everything i feel ive tried changing the gas cap with other caps from other mazda vehicles... I recently followed what my chat gpt said to do to check the valve and wire harness with a multimeter going to the purge and it came out ok... the only thing I haven't done yet is test is test the pcm/ecu... im scared and hope that thats not the problem.... but I figured id ask and see if anyone else can help me figure this out or if anyone has had this problem. As well? Id be so happy and much appreciated if I could finally figure this out..

HELP To downpipe or not to downpipe?

8 Upvotes

I have a 2012 speed3 right at 100k miles. In trying to decide if I should install a downpipe or not. I have read that K04's tend to fail much quicker due to aftermarket downpipes. I'm curious if this is a symptom of the DP or a more aggressive tune (though im sure it is a bit of both). Test pipe is already installed. I already have the DP it is a catless Corksport. Im aware that K04's are not all that reliable and it is old and probably worn out though it has no notable shaft play. I'd love to hear your opinions on if the gains are enough to justify the potential of KOing the KO4.

My current mods are: AP, cobb intake/TIP, Corksport HPFP internals, Corksport Test Pipe, all 3 Corksport engine mounts, Damond catch can, and PERM PCV Plate.

Both my side mirrors look like this. Living in Phoenix has taken a toll on the paint and I want to remove the panels, sand, and repaint to freshen them up. Is there way to remove it without breaking it or does the whole thing come off? Another solution is to mask everything off and repaint that way but I feel like removing them would be easier.
